Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.

Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: "5 on 4-1/2" means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)

Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: "8 on 6-1/2" means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)

Bolt Pattern - Side

Measuring the distance from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

Video Transcript for Review of Kenda Tires and Wheels - Tire and Wheel - AM31985

Today we're going to take a look at the Kenda ST175/80R13 Radial Trailer Tire in a load range D on this 13-inch white eight-spoke steel trailer wheel with the 5 on 4-1/2 inch bolt pattern.Now this is a Kenda Karrier Special Trailer Radial Tire. It is a special trailer tire design so it does couple the strength of a bias tire with the durability and stability of a radial tire. It is created specifically for trailers. It's not intended for use on other vehicles. They do use double steel belts, full nylon plies, combined for a nice superior function and long life. They use a nice computer generated tread design in premium rubber compound materials.

Gives you superior traction in wet or dry conditions.The wheel it's mounted on is a Dexstar steel trailer wheel. Has an eight-spoke design to it. It is coated with a night e-coat first. Then the white powder coat over the front and the back of the wheel. This will help resist rust and corrosion.

This whole tire and wheel assembly does meet the DOT, Department of Transportation, specifications.A few specs on this. We'll start with the wheel. The diameter on the wheel, which is always measured inside to inside or bead seat to bead seat, is 13-inch diameter. The width on just the wheel is four and a half inches wide. The bolt pattern on this wheel is a 5 on 4-1/2 inch bolt pattern.

If you want to measure that on a wheel like this, that's an odd number of lugs, in this case five, you just pick one of the holes. Let's say this one and then you'll measure across directly to either one of these holes but when you measure it's from the center of the starting to the furthest edge of the hole that you measure to. On this one it'll measure four and a half inches. This'll give you 5 on 4-1/2 inch bolt pattern.The weight capacity on just the wheel is 1,660 pounds. The wheel lug size this uses is a 1/2-inch by 20.

The pilot hole diameter, it's the large hole here in the center of the wheel goes over the hub on your trailer. The diameter of that opening is 3.19 inches.Now the tire size, which will be stamped on the sidewall, right down here it'll say ST for Special Trailer. 175/80R13. The R means it's a radial tire. Section width on this is seven inches. Overall diameter from the bottom to the top when it's inflated, it's 24.1. This tire is a load range D, which means it's an eight ply rated tire. It does have a maximum load capacity of 1,650 pounds at 70 psi.The last thing I do want to mention is most all the new trailer tires are coming through with a speed rating. It's designated on the sidewall by a letter designation. Right after the size we just went over, you'll see two numbers after it and then a letter M. The letter M will stand for 81 mile per hour speed rating.But that should do it for the review on the Kenda ST175/80R13 Radial Trailer Tire in a load range D on this 13-inch white eight-spoke steel trailer wheel with the 5 on 4-1/2 inch bolt pattern.

Had a blow out not too long ago on a trailer while towing our pontoon boat. Decided to replace both tires and after a lot of research I decided to go with the Karrier load star tires and rim combo... I placed my order during the weekend... My order was shipped out first thing that monday morning and was at my home thursday... btw, shipping was free....Just mounted the rims and tires on the trailer today so I can't say how good or bad the tires are, but this particular tire got better than avg. reviews, which is why I ordered it. My experience with Etrailer has been wonderful... Before placing my order I emailed customer service with a few questions.. got a quick response the next day.. When I called to place my order, the young man that took the order was very friendly, very courteous and most importantly very helpful... After the product was delivered I got another email from etrailer asking if everything was ok with the order. Like I said, customer service at etrailer has been exemplary. IF and when I have a need for trailer parts or products, I'll be going back to Etrailer to place my order... couldn't be happier with the way they handled my order... Roland 43520

etrailer.com had the d rated tires i needed, at a great price AND shipping included. They held the shipment until I returned home to replace the C rated tires I needed to buy while on the road. Great service, tech information (such as going to a larger tire). Really an excellent buying experience!! 145343

My opinion has remained the same, etrailer.com is very responsive to pre- and post-sales questions and performed as promised..

Not a big selection locally and all were load range C. For a few dollars more I got the better load range D tires. Working in the landscaping supply business (mulch, stones, gravel) it is painfully obvious how few people know the weights of these materials. A small amount weighs a ton, add in the weight of your trailer and soon you are pushing the capabilities of those cheaper tires and axles. Play it safe, when fixing the trailer upgrade to better tires, springs and axles. A small price to pay instead of a broken trailer breaking down or causing car accidents. 554463

After swapping the tires to rims of the correct bolt circle all has gone fine. The tires perform well with no odd wear issues at all. I just wish e trailer would publish bolt circle info, my advice is to call them if you have an odd size like tracker marine likes to use. At least I was able to sell the rims to someone else. Its all good. 390628

Thank you for your review. If you need to figure out your bolt pattern I have attached a link below that will help determine that. I hope this helps.

I bought another one for a spare. My spare has to be as good or better than the road wheels. Once the spare is used, I'd have trouble if the other one went. 391492

These wheels and tires have been great, only lost 5 lbs of air in the last year. Much better then the tires I had put on my old wheels by a local big box tire store. A belt broke in one of those tires after about a year and I noticed damage to the other. The price was about the same to replace both wheel and tire as it was to purchase tires and have them put on the old wheels locally. 424547

Second set of 13" radial tires for my boat trailer. First set lasted 5 years with no problems until recently as one of the radial tires had a belt separate (but no blow out). I had never balanced the old tires, but had read comments that it is a good idea to balance trailer tires. Glad I did, as both wheels needed weights, and one needed 2 ounces to balance! I can only imagine how important that will be in the smoothness of the trailer and longer tire life. I'm very satisfied with my tires and hope I can get another 5 years service out this set. 411451

I started out just wanting to replace the tires. It didn't take long to realize it's cheaper in the long run to buy the new tire mounted on the wheel; new tread, new valve stem, clean paint on the wheel, etc. I am extremely pleased with this purchase. I opted for radial tires VS. Bias tires and can tell that the radial tires track better than the bias tires I replaced. This is a hassle-free choice. 85559


Comments

After a yearalmost two seasons of hauling the pop-up throughout New England, the tires are like new. Its worth the little extra money I spent to have the tire/wheel together. The result is ZERO issues or problems!

BTW, eTrailer is terrific to work with. Of all the purchases Ive made in the last two years, eTrailer is the ONLY seller to ask for feedback one year later!!! They are serious about building relationships. Bottom line: excellent products, excellent service with Patrick, AND the tireswheels were delivered several days ahead of the promise date!

Bolt on and forget. They hold air very well. They ride very well. They do not flat spot when sitting. The powder coating on the wheels has help up very well. No regrets other than I caught my trailer on fire and learned that these also burn very well. Too bad. 434130

I burned mine but I did recommend them to my father who put a set on his boat trailer. He is happy with them as well.

Wheels/tires arrived one day sooner than expected - great. Wheels look good, tires look like tires - time will tell on those. I was glad to see the date on the tires was 38th week of 2018 - fairly "new" tires. Great service always from etrailer. I will order again for sure. Keep up the good work!! 658226

The tires arrived quickly and look good. I was disappointed to find that the tires had a manufacturing date of 3818, which means they were manufactured in September 2018, over 7 1/2 months ago. I noted in the reviews regarding tires that people were writing about how new the tires were based on the manufactured date. I guess there's no way of knowing until the tires arrive. 644189

Had one complete camping season with our SCAMP 16 ft, We picked these tires for the D rating.

We boast the Karrier radials to replace the OEM bias tires on our 2011 pop-up camper trailer. The choice was made for possibly better stability and tire wear on the 5000 mile trip we took to the southwest this spring. Tires on wheels arrived as promised. Wheels were a perfect match for OEM and left us with a spare set for for the next replacements. etrailer price and service were excellent. 452358

Great experience with etrailer. My first order and I went with them because of the reviews from others.

The 175/80R13 load range D tires and rims were received in good condition. They broke the box they were shipped in. After inflating them from 41 to the recommended 65 psi, I installed them on my camper. A previous identical set lasted 18-19,000 miles. I am quite satisfied with them. 414341

After 6500 miles, the tires are in good condition. Plenty of wear left in them. I will buy them again when needed.

Shipping was fast as usual which I am always pleased about. On the downside, I had contacted etrailer ahead of time about wanting tires less than a year old so as to avoid shipping to exchange out of date tires for in date. Unfortunately 3 were out of date (always check the manufacture date of trailer tires, they only last 5 years!). However mistakes happen so the five stars are for etrailer's quick response to fixing the situation by quickly sending me replacement tires even before I had sent the old ones back! I have always been very happy with their quick customer service responsiveness and the courtesy to have free videos they post to help customers, and really anyone, who need help with various trailer concerns. :-) I do not purchase trailer tires from anyone else as a result of their outstanding customer service. 412207

Do you have a question about this Tires and Wheel?


  • Can Trailer With ST145/R12 Tires be Upgraded to 13 Inch Tires
  • We have ST145/R12 trailer tires with a load range E, the Kenda Karrier S-Trail # AM10140. If you wanted to go to a larger tire and wheel you could do so but you would need to ensure you have the needed clearance of about three inches from your trailer tire to rim and four inches to your trailer frame. A ST145/R12 tire like the Kenda Karrier S-Trail # AM10140 measures 21.3 inches in diameter when inflated and is 5.7 wide. The smallest 13 inch tire is ST175/80R13 quite a bit bigger, measuring...

  • Tire/Wheel Combo Needed that is Rated for 3,500 lbs and Compatible with Dexter # 35545E-ST-EZ-89
  • I do have a solution for you, however, the smallest tire we have on a 13" wheel is part # AM31985 which has a load range of 1,610 lbs at 65 psi meaning it won't be strong enough for the 3,500 lb axle. The best option that you have is the Taskmaster Contender ST205/75R14 # AC14R45SM which comes with a 14" wheel that is compatible with the Dexter Trailer Axle # 35545E-ST-EZ-89 that you referenced. This tire/wheel combo has a load range of 1,760 lbs at 50 psi which means 2 of them will...

  • Replacement Tire Recommendation for an ST185/80R13 Size Tire on a Travel Trailer
  • The load range D on the Loadstar ST185/80D13 # AM1ST79 actually gives you a higher weight rating than the C load range. For this size D is 1,710 lbs at 65 psi while C is 1,480 lbs at 50 psi. It doesn't hurt to have a tire that is rated for more weight and the benefit to this tire is that it has a max speed rating of 81 mph. If you need a wheel as well then I recommend part # AM3S331 as this is the same tire but it comes with a white wheel that has a 5 on 4-1/2" bolt pattern. Bias tires,...

  • Can a Jet Ski Trailer go From 5.30-12 Tire to a 175/80-13
  • The 5.30-12 tire size is 21.9 inches in diameter and has a section width of 5.6 inches. The 175/80-13 has a diameter of 24.1 inches and a section width of 7 inches. So basically as long as you have room between the frame and the inside of your current tire for 3.5 more inches, and have room for 1.5 more inches between the top of your current tire and the fender you should be good. For a 5 on 4-1/2 inch bolt pattern rim and tire you would want the part # AM31985, for a 4 on 4 inch...

This combo have a load range D which is 1,610 lbs at 65 psi and has a max speed rating of 81 mph. The galvanized finish on the wheel is perfect for marine applications. It is a bit of a rougher finish and helps to keep the steel wheel from rusting and corroding. If you would rather stick with...

  • Difference Between Mini Mod Trailer Rim and Non-Mini Mod Trailer Wheel
  • The difference between the two rim designs you mentioned is just a visual difference. The mini mod wheels are a white rim that have small circles that run around the mounting flange of the rim whereas the other white style you referenced has triangles cut out instead. I attached a picture that shows the difference between the two styles with the mini mod being labeled. The rims in the picture are # AM31985 and # AM31991.

You will want to spend a few minutes spraying your wheels down after leaving the water to remove any saltwater residue, but most folks do that anyway. The Karrier ST175/80R13 is a load range D tire with a 1,660 lb weight capacity at 65psi. The # AM31998 uses the same tire on an aluminum wheel that is very...

  • Radial Trailer Tire to Replace Bias Ply 4.80-12 Trailer Tires
  • The closest radial tire size we offer to your 4.80-12 bias ply trailer tire would be the Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10140. This tire will be about an inch taller and wider than what you currently have. You will need to make sure your trailer has enough clearance for this.

These tires come in load range C (1,360 lbs at 50 psi) and load range D (1,600 lbs at 65 psi). Your tire load range should match or exceed your axle capacity. My research indicated that an unloaded 1998 Mesa with the standard manufacturer equipment weighs approximately 2,000 lbs, so while a lighter trailer load would let you get by with load range C tires,...

  • Trailer Wheel and Tire Recommendation for Pull Behind Camper with 2200 Lb Axle with 5 Bolt Pattern
  • I did some calculations and came up with two ST (special trailer) tires, one slightly larger and one slightly smaller than your 165/80R13 tire, which is 23.4 inches diameter. The slightly larger tire, Karrier ST175/80R13 Radial Trailer Tire, item # AM31985, is 24.1 inches diameter, has a 13 inch wheel with 5 on 4-1/2 inch bolt pattern and maximum load of 1,360 lbs at 50 psi. The slightly smaller tire, Karrier ST145/80R12 Radial Trailer Tire, item # AM10130, is 21.3 inches diameter,...

  • Does Karrier Radial Trailer Tire With White Wheel Have Offset
  • The wheels we carry will have the offset listed in the Specs section on the product page if one exists. The Karrier ST175/80R13 Radial Trailer Tire with 13" White Wheel, part # AM31985 you referenced has no offset on the wheel.

  • Availability of Radial Tire/Wheel to Replace 185/80D13 Trailer Tire/Wheel
  • We offer the ST185/80D13 tire in bias-ply only, that part # is AM1ST79. For most camper applications bias ply tires are more than adequate. But if you are towing your trailer often and over longer distances the radial tire will perform better and last longer than the same size bias ply tire. If you decide to go with the radial you can use the ST175/80R13 radial tire and 13-inch 5 on 4-1/2 wheel combination such as part # AM31985. Going to a smaller size tire like the 175/80-13 will not...

  • Upgrading Trailer Tire 175/80R13 from Load Range C to D Recommendation
  • A load range C ST175/80R13 tire has a 1,360 lb rating when inflated to 50 psi. So that would give you a total tire capacity of 2,720 lbs. It sounds like your trailer will be around 3,000 lbs when totally loaded to it's max so upgrading to at least a load range D would be a great idea as this will give you 1,610 lbs of capacity at 65 psi. For that you would want the part # AM10210. Trailer tires should always be inflated to the max PSI rating listed for the tire. If a trailer tire...

  • Capacity of 5.3 x 12 Tires and Wheels Compared to 175/80R13 Tires and Wheels on a Boat Trailer
  • According to our resident tire expert, trailer tires often fail because they are not used and maintained as much as automotive tires and/or they are not filled to the recommended psi which would cause a blowout. So it could be that type of issue, rather than the tires being too small. In this case, a load range D tire, 5.3 x 12, like # AM10068, is rated at 1,250 pounds at 105 psi. So total weight capacity of two would be 2,500 pounds. That is very close to the dry weight of the trailer,...

  • Replacement Trailer Tire Size for B78-13 Tires on Pontoon Boat Trailer
  • The tire size you referenced, B78-13, is a valid tire size. The metric equivalent size is ST175/80R13. The Kenda tire you referenced, # AM1ST74, is a radial trailer tire in this size. We also offer it pre-mounted on a 13-inch white wheel with a 5 on 4-1/2 bolt pattern as part # AM31985. This combination is rated as Load Range D, with a maximum load capacity of 1,610 lbs at 65 psi. Trailer tires should always be inflated to their maximum psi pressure as indicated on the tire's sidewall. An...

  • Availability of Replacement Wheel for Demco Kar Kaddy 3 Tow Dolly
  • We can indeed offer you a spare wheel for your Demco Kar Kaddy 3. The part number is # DM09296. It is a 14 x 5-1/2 inch wheel with a 5 lug on 115mm bolt circle. I've confirmed with Demco that is indeed the correct replacement wheel. You'd want to use a ST205-75R-14 Load Range C tire like part # AM10234. The # AM31985 you referenced wouldn't work well for you. It's a 13 inch wheel, not a 14 and the offset would be wrong.

  • What is the Speed Rating for Kenda Karrier ST175/80R13 Tire and Wheel # AM31985
  • The Kenda Karrier ST175/80R13 Radial Trailer Tire with 13 Inch White Wheel # AM31985 referenced in your question has a maximum speed of 65 mph, which is the standard rating for trailer tires. This is a really nice, durable radial tire and wheel combo that features a maximum load of 1,610 pounds at 65 psi. It includes a limited 2-year warranty. This is the highest speed rating for the ST175/80R13 sized tire in the Load Range D that we have available. If you are able to go to a lower...

  • Are Radial or Bias Ply Tires Better on Boat Trailer With 2 Axles
  • Given the choice I would recommend a radial tire over the bias tire because the radial tire will provide better stability and more ground contact resulting in a more comfortable ride. A radial tire is also going to have better tread wear over the bias ply tire. The radial tires will also run cooler and give you better traction. A cause for many tire problems is heat build up, especially when under a load, and the radial tires will dissipate that heat better than a bias tire. Bias...

  • What Needs to Be Considered to go to a Larger Trailer Tire Size
  • There are two main things to consider if you would like to use a larger size wheel and tire on your trailer. The first thing is the bolt pattern of your current hub. You will need to determine the bolt pattern of your hub so you can determine which bolt pattern rim you should purchase. The next thing you will need to consider is clearance. If there are wheel fenders you will need to consider vertical clearance. You will also need to consider the clearance from the wheel to the inside...

  • Comparing ST175/80-13 and ST185/80-13 Trailer Tires for a Coleman Casa Grande Trailer
  • First, you should go with the tires that are recommended by the trailer manufacturer. This information should either be on the trailer tongue or frame somewhere or in the literature for the trailer. Trailer tire sizes ST175/80-13 and ST185/80-13 do fit the same size wheels and are about the same height (24.1 inches and 24.4 inches respectively). The 185s are wider by 0.394 inches. If you went with the smaller ST175/80R13 then for up to 3,000 pounds gross trailer weight you would...

  • Choosing Between Radial or Bias Ply Tires for Boat Trailer
  • The only instance where we might conceivably recommend a bias ply tire over a radial tire would be for farm or agricultural use where the tire would primarily be used on non-paved surfaces. This is due to the fact that the thicker sidewalls used on bias-ply tires would offer more stability. For a boat trailer, or any other trailer used on pavement a radial tire is preferable. A radial tire will have a more flexible sidewall, which provides better tread contact with the pavement. Radial...

  • Could a 4.80-12 Wheel and Tire be Replaced with a ST175/80R13 on a Pioneer Pop up Camper
  • You would be increasing the overall diameter of the tires from 20.5 inches to 24.1 inches if you went with the part # AM31985 that you referenced. If you have room for 1.8 inches less of fender clearance then the wheel and tire you mentioned would fit just fine.

  • Should I Upgrade From a 12 inch Tire to a 13 inch Tire on a Rockwood Freedom 2290 Trailer
  • I would recommend staying with the 12 inch 5.30-12 tire, like the Kenda K353 Trailer Tire, item # AM10068, for a couple of reasons. First, going with the larger, higher capacity tire will provide a stiffer ride for your trailer suspension and trailer. This will cause wear on the suspension parts. Next, going with a higher capacity larger wheel and tire than recommended by the manufacturer or axle capacity makes the trailer suspension the weakest link in the system. If a failure occurs...

  • Replacement Wheels and Tires for 2001 Rockwood Freedom 2290 Tent Camper
  • A 13-inch tire will go about 3 inches higher than your current tire and will have a width of about 6.9 inches—a little over an inch larger than your current tire. We recommend leaving 4-1/2 inches of clearance between the top of the tire and the trailer, so with 8 inches between your tire and wheel well, you'll still have plenty of space with the larger tire. We have several options for Karrier ST175/80R13 tires. The largest load range available, a load range D, supports up to 1,610...

  • Can a Camper With ST175/80x13 Load Range C Tires Be Upgraded to Load Range D Tires
  • Going from a ST175/80x13 load range C tire to a load range D tire in the Kenda Tires and Wheel, part # AM31985, is no problem. As you mentioned, changing to the higher load range will not increase the amount of weight that your camper can carry. If you are using radial tires there will be a bulge look to the sidewall of the tire because of the way a radial tire is constructed. Since the belts or cords inside the tire run from bead seat to bead seat across the radius of the tire it gives...

  • Increasing Wheel and Tire Size to Increase Trailer Ground Clearance
  • By going with the 5.3x12 tire, you will gain 1/4 inch in width and 3.8 inches in diameter which would gain you approximately 2 inches of additional ground clearance. Other than having to move or modify your existing fenders, going with the larger tire size will work just fine for you.

  • Age of Kenda 175/80R13 LRD Tires
  • We sell quite a few trailer tires, so for the most part, they don't hang around here for long. Most of the tires we have in stock in the more popular sizes will have DOT date stamps within the previous calendar year. Slower movers might go back a bit further. Since the 175/80R-13 is a very popular size, we sell through our shipments quickly. Keep in mind that a tire on a warehouse shelf isn't exposed to the weather or UV radiation which can break down tires over time.

  • How to Determine if a Trailer Wheel is Hub-Centric or Lug-Centric
  • First, I would say if there is any question on the road worthiness of the trailer, take the steps to correct it. Better safe than sorry. Some trailers have wheels that are hub-centric, the wheel is centered on the hub using the center pilot holes. Other trailers have wheels that are lug-centric, the wheel is centered on when you tighten down the lug nuts. To determine which one you have on your trailer, take a look at how the wheel attaches to the hub. If it uses wheel bolts, like...

  • Increasing Wheel/Tire Size on Carry-On Utility Trailer

I've provided you a cutaway diagram of a wheel showing where the measurement would be taken. Given the tire size, you have a 12 inch rim. There are a few things you'd need to check before going with the larger 13 inch wheel w/ 175/80-13 tire. The 175/80-13 tire is approximately 3-1/2 inches larger in diameter, which would bring...

  • At What Age Should Trailer Tires Be Replaced
  • Trailer tires should be replaced about every 6 or 7 years, even if the tread is still in good shape. As tires age, they can crack and dry rot. Continuing to use the existing tires would be dangerous. Changing to a 13 inch wheel will move the tire closer to the underside of the fender by at least a 1/2 inch. Typically, you'll want to see a minimum clearance of 3 inches between the top of the tire and the underside of the fender when the trailer's fully loaded. If you'd care to reply...
