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"

by:

very happy with this tire & wheel combo....love having them come mounted and ready for installation also the galvanized rims give the appearance of chrome wheels also a plus




by:

My order was received ahead of schedule which was excellent. Perfect communication. The tires were excellent. The galvanizing isn't high quality from from 6 feet away it looks good. This is the best place to order parts for my pop up period.




by:

I couldn’t be happier with the wheels/tires I purchased. The galvanized finish is nice and shiny. They almost look polished. The tires felt great. Nice and smooth while towing up to 80mph. Had no issues at all on my trip. Huge thank you to Brent J who helped me purchase them, and provided excellent customer service.




by:

I ordered these to place on my boat trailer. I used them on my 2012 Trailstar trailer which carries my Tracker bass boat. It had load range C tires. I wanted to upgrade my tires and this item was exactly what I wanted. These fit perfectly. The tires were “fresh”....meaning that they were made only a months ago. The finish on the rims was much better than I was expecting. The welds on the back side of the rims looks to me to be quality work.


Comments
It’s been a year and I have absolutely no complaints. I would definitely purchase these again.

I'm happy with the Radial Tire and Galvanized Wheel package etrailer helped me with. Between the pictures and video of the product on the website, multiple questions submitted and answers received (even though I interfaced with multiple agents on the phone and email, they're all up to speed on customer information), packaging, product quality, price, ease of purchase, and follow up after receiving the delivery(which was prompt), It's been an excellent experience! I will use etrailer again for future purchases and recommend as first choice!




by:

Ordered wheels and rims , took 2 days to get them. That is fast easy ordering, shipping and galvanizing that almost looks like chrome.
Now to get another boat so I can re-order tires and rims...




by:

Tires are great but the wheels look loke they were chromed by
6 year old children. Have not even removed the plastic wrap from them.
I should have held out untill 2023 for the wheels I wanted in the first place. I will not be using these wheels till next summer anyway.
Never been let down by you guys before, thats a shame. Guess this is the way companies are run now a days. If you still want to trade these for the ones I ordered, let me know. Otherwise I am stuck with them.




by:

Fast shipping and great quality looks perfect on our Shasta!

I needed to replace the worn out tires on my flatbed utility trailer and had been concerned about the weight capacity of the load range C bias-ply tires that were installed by the local tire shop just after I bought the trailer - combined 2700 lbs on 3500 lbs axles, 5400 lbs total. A couple of times, I've had 4000 lbs of landscaping bricks from the home improvement store plus the 1300 lbs trailer weight rolling down the highway. With these load range D tires, the combined tire weight rating is now 6400 lbs. I'll gladly pay the extra few dollars per tire for the LR D's over the LR C's for that piece of mind plus these galvanized wheels look a lot better than the old white rusty wheels do.




by:

Tires were ordered on Good Friday and showed before noon on Tuesday. Great service as expected.

The tires are very nice and there was no shipping damage. I think they will work great on my camper for this years long distance tow.

Only little complaint is that the rims don't look like a lot of finish work went into them. They are rough, almost look like they were spray painted rather than galvanized. Surface has drips and runs. But otherwise is well covered and I don't anticipate them rusting like my old white painted rims did.

They may look better with a bit of hand polish work. But they are trailer tires not mag rims on a GTO so I can live with it.




by:

First time purchasing from etrailer.com and I was very pleased with the prompt shipping and quality of the products I purchased. Purchased a set of new pre-mounted tires and wheels for my boat trailer and spare tire carriers for my boat and jet ski trailers.




by:

Solid products with competitive pricing and excellent customer service. No reason NOT to shop at Etrailer. They check all of the boxes!




by:

Finding just what I was looking for was easy on the website and it was delivered on the projected date.




by:

After inadvertently ordering the wrong tire for my trailer I called the support number and was fortunately helped by Roger. He arranged for the return of the incorrect tire and placed the order for the correct one. Also gave me some good tips on proper tire inflation and load ratings. Thanks again for all your help!!!




by:

Good to go . Ordered a spare tire recieved it with no problems.




by:

Tires & Rims came fast. I purchased these because of the high load rating and the fact that they already came mounted on galvanized rims, ready to go. 1 year later and so far so good. I had a close call with a set of cheaper bias ply tires. It's just not worth your (or your family's) safety or the chance that a blown tire will ruin your entire weekend. Don't cheap out on tires. Get a good set like this and go out and have fun with the piece of mind that you will make it there and back safely.




by:

We are really pleased with our tires and wheels. The order was in a timely manner. Thank you




by:

Great service , the wheels and tires look great on my Tracker 175

Put these tires on my tracker 175. I have pulled the boat several miles and they still look new

Quick service, delivery and good tires.




by:

great tires and rims




by:

Wheel & Tire package were exactly what I needed. After having not one but two blow outs on the boat trailer while going to the lake I needed replacement fast. E-trailer had what I wanted and their customer service is second to none. I really don't go anywhere else when it comes to getting things for my trailer.




by:

etrailer employees are really good! The only negative aspect was the shipping using UPS but could be related to local UPS service center!




by:

Wheels and tires look to be of good quality were shipped quickly and packaged very well for shipment, received prompt with no damage. Since I have not used yet I will update later if this site allows




by:

Fast delivery, great pricing. etrailer came through for me!




by:

Just got them, so don't know anything about tire quality. They look good though and I trust Kenda"s quality. The wheels galvanization is somewhat rough, but thorough. Your customer service is as good as any. and , That is the type of company I support.

  • Spare Trailer Tire for a 1968 Shasta Travel Trailer with ST175/80R13 Tires
    Trailers do not have a donut type of spare available as an option. Trailer tires are built differently than passenger vehicle tires. They are made with a thicker sidewall to handle more vertical load. A donut would not be sufficient. You would just use the same size tire and wheel as a spare as what is already on the trailer. In this case use an ST175/80R13 tire. I have included a link to the right to all of the tire and wheel combos we have in size ST175/80R13. We have a lot of spare...

This tire/wheel combo has a 13 inch diameter rim that is 4-1/2 inches wide, and a 5 on 4-1/2 bolt pattern. The pilot hole diameter is 3.19 inches. This is a Load Range D tire and has an 8 ply rating with a maximum load rating of 1,610 lbs at 65 psi.

  • Whats the Difference Between the 4.00x8 Tires and the 4.80x8 Tires
    There is no difference between a 4.00-8 tire and a 4.80-8 tire. We list them on our site as the same and as the size 4.80/4.00-8 to let people know that they are the same size. I attached a link to a page that has a chart on trailer sizing as well as a link to a page that has all of the 4.80/4.00-8 size tires we offer.

  • Are Kenda Karrier Trailer Wheel/Tire Combos Factory Balanced
    The wheel and tire combos we sell are not balanced at the factory. When the tire is mounted to the wheel, the high (heavy) spot on the wheel is matched to the low (light) spot on the tire, which leaves the wheel and tire somewhat balanced. You may have the wheel/tire professionally balanced if you wish, but having perfectly balanced tires is not as important with trailer tires as it is with a passenger vehicle. I have linked you to our Tire and Wheel help article that contains more helpful...

  • Changing Boat Trailer Wheels from 12 to 13 Inch Diameter
    For a 13 inch wheel and tire combo, the tire sizes would either be ST175/80-13 or ST185/80-13. The 175/80-13 measures 24.02 inches in diameter, while the 185/80-13 measures 24.65 inches in diameter. This is considerably larger than the 4.8-12 wheel and tire that has a 20.5 inch diameter. The wheels on these combos are typically 4-1/2 inches wide, with the alloy wheels being 5 inches wide. If your boat trailer can accommodate the larger diameter and width without having any clearance problems...

  • What Size Trailer Tires Will Replace B78-13 Trailer Tires
    A trailer tire size 175/80-13 will replace either an A78-13 or B78-13 trailer tire. A 175/80-13 is going to have 3 load ratings: B at 1,100 pounds at 35 psi, C at 1,360 pounds at 50 psi, and D at 1,610 pounds at 65 psi. This size will have a diameter of 24.1 inches. This tire size will fit on a 4-1/2, 5, or 5-1/2 inch wide wheel. If you choose tires rated higher than your axle, you still have to go by the axle weight capacity. If you choose tires rated lower than the axle capacity, then...

  • Recommendation to Replace 155R13 Tires on Boat Trailer
    The 155Rx13 tire is an older size that's not used much at all anymore, which is why you're having so much trouble finding an exact replacement. Because of this your best option is to replace the tires with the closest current/modern trailer tire size available, which is a 175/80R13 model. A 175/80R13 trailer tire has an overall diameter/height of 24 inches and a width of 6.9 inches. This is about 1.2" taller and 0.8" wider than what you currently have. As long as you aren't already cutting...

  • Best Radial Trailer Tire in Size of 175/80R13
    In the tire size of 175/80R13 the best trailer tire option is the part # AM31994 which is a radial, has the highest speed rating at 81 mph, and is Load Range D with a weight capacity of 1,610 lbs at 70 psi.

  • Best Trailer Wheel and Tire for Replacing B78-13ST
    Radials are definitely better for your application. At this point it's actually pretty rare that the bias ply is the better way to go but for what you mentioned radial is better for highway use. So for a wheel and tire with a radial construction, a higher speed rating of 81 mph, and a 5 lug bolt pattern the Karrier part # AM31994 would be your best option.

  • Smaller Trailer and Wheel Size for Trailer with 215/75-14 Tire Size
    Best option is the 13 inch wheel and tire size you mentioned of 185/75R13 like the Karrier ST175/80R13 Radial Trailer Tire # AM31994. The 195 -75r 14 size you mentioned is a passenger vehicle tire size and definitely should not be used on a trailer. The # AM31994 will fit easily like you want and would have more than enough weight capacity so it will work great. The wheel is also galvanized steel so it will fight corrosion too.

The pilot diameter is 3.19 inch too which is slightly larger than what you have now but will still work great. Overall diameter of the tire is 24.1 inches and the section width is 7 inch.

  • Solution for 14 Inch Tires Rubbing Against the Fender
    We do not recommend using spacers because it can cause otherwise avoidable issues with your tires and hubs. There are not smaller 14 inch tires and because you do not want to remove the fenders the best option is going to be replace both your wheels and tires with a smaller capacity. The most important thing to know before doing this is what your hub's bolt pattern is.

    You are correct, the older tire size of A78-13 is the current size 175/80-13 like the # AM31994. The 5 on 4-1/2 inch bolt pattern is the wheel bolt pattern size that the holes of the wheel have to mount up to the trailer hub. Not all wheel bolt patterns are the same but if the trailer has a 5 lug bolt pattern there's a very strong chance it has the 5 on 4-1/2 bolt pattern. The 3.19 inch pilot diameter is the center hole diameter of the wheel that fits over the bore of the hub. Most trailer...

  • Can a Smaller Tire be Used With Snowmobile Trailer?
    The ST205/75R14 tires you have are designed to fit on 14" wheels, and there are no tires which would be shorter you could use on 14" wheels. What you would need to do instead is get a new wheel and tire combination that would allow you to use a smaller tire but still have the right load capacity. To do that you would need to know your wheel's bolt pattern; I've added a link to a help article which details how to determine your bolt pattern. If you have a 5 on 4-1/2 bolt pattern, which...

  • Can 12 Inch Trailer Tires and Wheels be Replaced with 13 Inch
    The smallest diameter 13 inch trailer wheel and tire will have a diameter of 24.1 inches (ST175/80-13). There are 3 common 12 inch trailer tire sizes: 4.80-12 has a diameter of 20.5 inches, 5.30-12 has a diameter of 21.9 inches, and 145/80-12 has a diameter of 21.3 inches.

  • What Type of Tire Should be Used on a Motorcycle Trailer
    Some tires are specially designed to be used on trailers. These tires include the letters "ST" in the size specification that is listed on the sidewall. The "ST" stands for "special trailer". This kind of tire has a stronger sidewall than an automobile or truck tire so it can handle higher air pressures and higher loads. For a trailer I cannot recommend you use a passenger vehicle tire regardless of how small or lightweight the trailer is. The main difference between a radial ply and...

  • Do the Trailer Rim and Tire Combinations Come Balanced
    The trailer tire and wheel combination is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. I would recommend to balance the tire and wheel combination at a local...

Trailer tires do not really need to be fully balanced the way vehicle tires do but you could have them balanced if you wanted. These items are mounted together so that the wheel's heavy spot mates up to the tire's light spot; this is not the same as a full dynamic balance but it is fine for trailer use.

    Since this tire is 175/80-13 bias tire, tires of this size have weight ratings up to 1,100 to 1,610-lb maximum load at 65 psi. This information is based on current tires we sell that are the same size like # AM31994. So the rating that I listed is not promised to be accurate, but this information can be used as a guide. If you are trying to determine the load capacity of the trailer you will need to use the axle to determine that. The easiest way is to look for a plate or sticker somewhere...

    The wheel/tire products we sell, such as the Kenda # AM31994, have not been given a full dynamic machine balancing but what is done is that the tire's light spot and the wheel's heavy spot are aligned by the distributor. This is not the same as a full machine balancing that is essential for vehicle tires, but it is usually fine for trailer tires so they don't require any further balancing. Passenger vehicle tires must be dynamically balanced for proper operation. If you know a local...

  • Is it Necessary to Fully Balance Trailer Tires
    First, thank you for your many purchases from us here at etrailer, including the Kenda Karrier tires # AM31994. Trailer tires that we sell come from the distributor already mounted to the rims. These do NOT get a full dynamic balance the way new vehicles tires do but they don't actually need this. When the tires are mounted to the rims the light spot on the tire is matched to the heavy spot on the wheel. This provides a degree of balancing that is sufficient for trailer tires. You can...
