Radial Tires vs. Bias Tires

Radial tire vs bias tire graphic

Radial ply tires are designed for trailers that are towed on the highway. The cords on a radial tire are positioned at a 90-degree angle to the direction of travel so that they lay across the width of the tire from wheel lip to wheel lip. This construction prevents the cords from rubbing against one another when the tire flexes, unlike the cords on a bias ply tire. As a result, radial tires have less rolling resistance and heat buildup, which leads to a longer tread life and improved steering at higher speeds.


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

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

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

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..

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.

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

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.

Item # AM31985: Good value in a wheel/tire combo. Shipped quickly and received in good condition. Installed on our single axle camper and worked perfectly on a 600 mile first trip. Bought these instead of tire only, so we could have spares. I like the tread on these tires. Very satisfied so far. 800667

These replaced the old tires that came on the trailer when I bought it. They looked good but were over 5 years old. Also, the speed rating was only 65 miles an hour. I learned a lot about trailer tires after I had a blowout on I75 at 75miles an hour. Thank God for the anti-sway bar. I went with tires and rims just because it was easier and always replace all tires at the same time. I also learned to always check tire pressure and after storage go slow for a few miles before going at highway speeds. 798086

  • Correct Tire Pressure for 5.30x12 Trailer Tires
    In order to realize their full weight carrying capacity, trailer tires should remain at their maximum pressure as stated on the tire's sidewall. When fully pressured up, your current tires have a capacity of 2170 lbs per axle. When you subtract the 1300 lb weight of the trailer, you're only left with 870 lbs for payload. Running at a lower pressure rating reduces the weight capacity of your tires, but the actual capacity is unknown because the tires are tested at the recommended full pressure....

  • 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.

  • 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. I attached a couple FAQ articles on trailer tires for you to check out as well.

  • Radial Tire Recommendation for Size ST205/75D15 Replacement
    I would recommend you stick with the same size tire you currently have except a radial like what others have suggested. For that you would want the part # TTWTRTM2057515C. For tire wear and capacity reasons you always want to keep your trailer tires inflated to their max psi. A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. A radial tire will normally run cooler than a bias ply tire, especially when the tire is under...

  • Can Bigger Wheels And Tires Be Used On Camper
    In order to be able to place bigger wheels and tires on your camper, the first thing needed is the bolt pattern you have on the existing wheels you wish to replace.

  • 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...

  • Best 13 Inch Trailer Tires and Wheels for a 1500 Pound Casita Trailer
    All wheels are not created equally! And the same goes for tires. The P in front of your tire size indicates that the tires are for passenger vehicles, not trailers. This is a problem because trailer tires and vehicle tires are constructed differently. Trailer tires are built with a thicker sidewall than passenger vehicle tires to handle more vertical load. You really need to switch to ST (special trailer) tires for your trailer. The wheel, since it came off of a trailer, will be fine...

  • Recommended Tires And Wheel Size 175/80R13
    Since speed isn't the big concern for you, I recommend the Kenda Karrier ST175/80R13 Radial Trailer Tire with 13" White Wheel - 5 on 4-1/2 - Load Range D # AM31985. It will have a higher ply rating which means a stronger sidewall. It has a load capacity of 1610 lbs at 65 psi. This is a very nice radial tire and the wheel has an e-coat base with white powder coat for rust resistance. This will be a great tire combination for you that will allow you a slightly higher load capacity. Another...

  • Can a Jet Ski Trailer go From 5.30-12 Tire to a 175/80-13

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.

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.

  • 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,...

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.

  • 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...

    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...

  • Increasing Wheel/Tire Size on Carry-On Utility Trailer
    You do indeed have a 12 inch rim. When you measure the diameter of the wheel, you'll need to measure the diameter of he wheel where the tire bead meets the wheel. 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...

  • Spare 4.80-12 Wheel/Tire for Yacht Club Boat Trailer
    As far as the tire size discrepancy goes, I believe you have 12 inch diameter wheels, if you indeed have 4.80-12 tires. You can't fit a 12 inch tire on a 13 inch wheel, but if you measured the wheel from the wrong spot, you can easily come up with 13 inches (see diagram I've provided). As long as the 4.80-12 tires/wheels are working well for you, there wouldn't be any good reason to switch to a different size. Unless you have an extra wheel lying around, you'll need a wheel/tire combo....

  • 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 4.80-12 Trailer Tires and Wheels be Replaced by 175/80-13 Tires and Wheels
    The radial tires at size 175/80-13, are going to be 7 inches wide; too wide to be able to fit without incident on your trailer, so you will need to go with a bias ply tire. The wheels that we carry, unless otherwise noted, have a zero offset. This means that the extra width will be split evenly on each side of the tire. However, there will be very little room if you just have 1-3/4 inches of clearance. Make sure you double and triple check the measurements before ordering. As you are...

  • 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...

  • Can 13 Inch Trailer Tires Be Used in Place of 12 Inch Trailer Tires
    The ST175/80-13 trailer tire size is approximately 3.6 inches taller than the tires you have now. Half of that is applied above the axle center line so there will be less than 1/2 an inch of clearance between the fender and the top of the tire. You should have about 3 inches of clearance to account for travel of the suspension. Going to a 13 inch tire will not work unless you can raise the fenders up about 2-5/8 inches. What you could do is go to a 145/80-12 tire such as # AM10140. It...

  • 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...
