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"

Swapped out the steelies and low speed tires the trailer came with for the lighter aluminum wheels with higher speed tires. They tow great behind the sidecar and look a treat.

Wheels and tires are great, alittle taller and wider that the original trailer steelies so they ride the bumps better. Took out a couple of leaves on the springs which also helps given total trailer weight loaded is only about 350lbs.



by:

Had them for a year, 2-3k miles. They have been great! Solid to 110mph, handle well, the wheels still look sharp.



by:

I received my order and one wheel is four hole and one is five hole. I ordered four hole wheels.

I apologize for the mistake on our part. Customer Service will be in touch with you so that we can have the correct wheel shipped out.



by:

Tires and rims look awesome. Just wish they weren’t already a year old when I got them. They need a better way to keep stock newer



by:

I get a lot of comments from my fellow sailors now that I fitted these rims to my boat trailer. For me they weigh less than galvanized and never rust. The fact that they look great is a bonus. Took the trailer from California to Texas and back and the tires still look good.



by:

excellent service and back up on your products. there was a small hickup on the order and you made the correction the same day I called. couldn't be more pleased with the service and support.



by:

Excellent customer service. Aluminum wheels and new radial tires from etrailer are improved look and quality for the Bunkhouse camper.



by:

There was a mistake made but they corrected it right away.... Rims and tires look good



by:

Great quality and quick delivery. The 12” standard wheels that came with the trailer weren’t adequate and these replaced them well.



by:

These wheels and tire look like they will do the job, but i will not be able to try them on a long trip till spring, but they do look very nice.



by:

Great looking wheels! I would absolutely buy these again. Dresses up my restored Gator trailer.



by:

Order arrived fast and look great. With zero miles on them yet, I can't review further.



by:

Purchased a tire and wheel package to replace same, on a motorcycle towed trailer. My tires arrived already mounted on the wheels, making for a very simple swap out on the trailer. Thank you e-trailer for a painless shopping experience. I have no doubt that the radial tires will track and wear much better than the old two ply tires.



by:

I was very impressed with the informational videos to help make the decision and immediate follow up to my order. Furthermore a direct follow up with order from a live person. She was helpful and very willing to make sure everything is perfect. Fast shipping and was surprised how quickly it got here. On arrival everything is perfect. Thanks so much. I will be using you guys again! Can’t wait to pull my used trailer with the new wheels and tires!



by:

Great product



by:

Tires and rims are great. Customer service helped me in selecting the right tires. Couldn’t be more happy! Great products and great customer service. Will be back for sure.

Tires have worked out great ! Super happy!



by:

They arrived on time and in a very good shipping box. I am very pleased with my first purchase from etrailer.com. I talked with Jesse M. and he was very helpful. I will continue to shop etrailer.com for all my next purchases.



by:

Fantastic purchase. The wheels are exactly what I hoped for. The tire seems to be very good quality as well.



by:

Great looking wheels with nice tires!



by:

Hello Steve, Thanks for all you help. The lug nuts I called about were actually 12mm x 1.25. Les Schwab was able to verify the size. So close to the 1/2 x 20 that they would go on, but did not feel right. Again thanks for your help, I am happy with the wheels and tires and appreciate the time you spent hrlping me out.



by:

I ordered the Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel to replace the 12 x 5.30" tires that were on my tent trailer. I received the new wheels VERY fast, in only three days time and was very pleased. The tires are approx. 1/4" smaller in diameter than the ones they replaced, but since they have a flatter tread profile it is hardly noticeable. the tires are slightly wider than the ones they replaced, and the tread is a flat profile, like that of a car tire. The rims appear to be of high quality as do the tires. I am one happy camper!



by:

Stickers on the front of rims are very difficult to remove. There is no way to remove them without using a scouring material, even after soaking area numerous times since delivery. No very happy having to spend more than 2 hours trying to make brand new tires and wheels, right out of the box, presentable. Didn’t anybody realize that putting stickers that say “how to remove stickers” would be unnecessary IF STICKERS WERE NOT PUT ONE IN THE FIRST PLACE!



by:

We Americans love good looking wheels and tires. They can usually make or break the look of a vehicle. These rims are beautifully crafted and appear to be of good quality. Time will tell..
I'm trying a D range Radial trailer tire for the first time. With a couple of cross country trips planned for this summer, I'm hoping that they will run cooler and longer than the bias tires which seem to age very quickly.



by:

These tires are as advertised and the wheels are also excellent. Excellent value, excellent quality. Additionally, when you call this merchant with a question they have an incredibly responsive customer service department, who bend over backwards to help you. Just an all around great business. With my two boat trailers and RV I will be back here exclusively in the future.
Thanks etrailer... Tow thumbs WAY UP!!!



by:

Stylish rims and radial trailer tires for the price of bias-ply. Awesome!!!
These tires provide a higher load range and a smoother ride.
Ordered on a Monday and delivered to California on that Thursday!
Very satisfied.

  • Replacement Tire and Wheel with Aluminum Wheels for a 1995 Jayco Pop-up Trailer
    To determine if any of the tire and wheel combos we have will work with your 1995 Jayco pop-up trailer you will need to look at the existing tire size and he bolt pattern. I have included a link to the right that explains how to measure for bolt pattern. If the wheels that you have now are held onto the hub using lug nuts then you can use the aluminum wheel that comes with combo # AM31208 provided that the outer diameter of the center of the hub is 2.8 inches in diameter or less. You will...

  • 12 inch Wheel and Tire Combo with 4 Bolt Pattern and Higher Speed Rating
    We have a 12 inch tire and wheel combo that has a 4 on 4 bolt pattern like you need with an 81 mph speed rating with the part # AM31208. The tire size is ST145R12 which would still work for you. We don't have either size you mentioned with the higher speed rating.

  • What Should 1/2 Inch Lug Nuts on a Trailer Tire be Torqued To
    For a 1/2 inch lug nut which is what is used on the Kenda KR25 ST145R12 Radial Trailer Tire with 12 inch Aluminum Wheel, # AM31208, you will torque then down to 75-85 foot pounds.

  • Lug Nuts Recommended To Fit Kenda 12 Aluminum Wheel
    You are correct that a longer lug nut is often needed vs a regular lug nut switching to this Kenda Tire # AM31208. There isn't enough space on a regular length lug nut for a tool to get a good grip. The Americana Trailer Wheel Lug Nut - 3/4" Diameter - Stainless Steel - 1/2" - 20 Item # AM26NR is my lug nut recommendation for these tires. You can also use Chrome Trailer Wheel Lug Nut - 1/2" Item # 12CLN. Both of these are are 1-1/4 inch long vs. your 1/2 inch current set so the additional...

  • Appropriate Air Pressure and Weight Capacity of # AM31208 Wheel/Tire Combo
    Both the wheel and tire are rated for a maximum capacity of 1220 lbs. The particular tire used on the combo should be kept inflated to 65psi, but the wheel itself can be used with tires that take up to 80psi. There is no minimum acceptable pressure, a trailer tire should always be kept inflated to the maximum air pressure listed on the tire sidewall. Due to the thicker tire sidewall used, under inflating a trailer tire can lead to excessive heat build-up and can accelerate tire wear. A...

  • Can ST145R12 Tires Replace 5.30-12 Tires On Jayco Pop-Up Camper?
    Yes. The Kenda KR25 ST145R12 Radial Trailer Tire with 12" Aluminum Wheel - 4 on 4 - Load Range D # AM31208 you were looking at will replace the 5.30-12 tires on your Jayco Pop-Up camper since the ST145R12 is only 1/4" wider and just over 1/2" shorter than your current tires. The # AM31208 has a wheel with the 4 on 4" bolt pattern, so if this matches the bolt pattern on your Jayco this would be a great replacement. If your Jayco has the more popular 5 on 4-1/2" bolt pattern then I recommend...

  • Replacement Wheel and Tires for a 1965 Aristocrat Lo-Liner Travel Trailer
    Tire sizes that start with the letter P are for passenger vehicles and shouldn't be used on a trailer as they aren't designed for the vertical loads that trailers will see. Your overall tire diameter is currently 22.7 inches and the width is 6.1 inches. For a setup that would be just slightly smaller than what you currently have and comes with a 4 on 4 inch bolt pattern wheel I would recommend the part # AM31208.

    For a 16 inch steel wheel with 1/2 inch wheel studs, 90-120 ft-lb is recommended. For a 16 inch aluminum wheels, 90-100 ft-lb is what you should use. Be sure to recheck the torque frequently.

  • Would Bearing Buddy BB2047SS Fit Trailer Wheel AM31208
    Bearing Buddies aren't normally picked out based on wheel size since they fit into the trailer hub bore, but the diameter of the Bearing Buddy # BB2047SS is compatible with the trailer wheel part # AM31208. The diameter of the Bearing Buddy is 2.047 and the center hole diameter of the wheel is 2.80 inches.

  • Trailer Tires or Tire and Wheels to Replace A78-13ST Tires on a ShoreLander Trailer
    The modern equivalent of the A78-13ST is ST175/80-13. Since that size will not work for you the only option is to go to a 12 inch tire and wheel. The other places must have only had a limited selection because you can get a 145/80-12 with a capacity as high as 1,520 pounds. If the trailer has a 4 on 4 bolt pattern, see link on how to determine bolt pattern, then you can use tire and wheel combo # AM31208. This is a radial tire on an aluminum wheel so it would be excellent for marine use....

  • Lug Nut Recommendation for Kenda KR25 ST145R12 Radial Trailer Tire with 12 Aluminum Wheel AM31208
    You will most likely have to go to a longer lug nut when switching to aluminum trailer wheel # AM31208. There isn't enough space for a tool to get a good grip on a regular lug nut. The recommend lug nut is Americana Trailer Wheel Lug Nut - Stainless Steel - 1/2"-20 - Qty 1 # AM26NR. It is sold in quantities of 1. You could also use Chrome Trailer Wheel Lug Nut - 1/2" Item # 12CLN. It is also sold in quantities of 1.

  • What is the Speed Rating for Kenda KR25 ST145R12 Radial Trailer Tire
    Kenda ST145R12 trailer tire # AM31208 is rated for 65 miles per hour. I do not recommend doing 70 miles per hour when towing a trailer if for no other reason other than the tires are not rated for it. What will happen is that the higher sustained speed will produce excessive heat. Heat is the number 1 enemy of tires. What can make this even worse is that trailer tires are built with a thicker sidewall compared to passenger vehicle tires. If under inflated the thicker sidewall will produce...

    Your ST145R12 # AM31208 wheel has a diameter of 21.3" so you were close with the # CE27410 but just needed to go one size larger to a cover like the Classic Accessories Custom Fit Spare Tire Cover - Model 1 21"- 22" Snow White # 052963751000.

  • 13 Inch Trailer Tire Recommendation for Landscaping Trailer
    You would need to go with a trailer tire that has ST before the size as they are the only tires rated for use on a trailer. You would need to go down to a 12 inch tire and wheel so that you can go with something that will fit your trailer. For that you would want the part # AM31208 for if you have a 4 lug bolt pattern or part # AM31202 for if you have a 5. These wheels overall diameter will be just a tiny bit smaller than the size you currently have that does fit.

  • What Type of Valve Stem Does The Kenda Tire and Wheel # AM31208 Have

The representative informed me that there is a regular valve stem on the Kenda Tire and Wheel # AM31208. She informed me that they have not had any customers have issues with the valve stems. The valve stem installed is sufficient to hold the air pressure of 65 PSI, which is the maximum PSI for the tire. With ST trailer tires, you want to make sure to have the tires inflated...

  • Recommendations for Larger Tires on Jayco Pop-Up Camper
    One of the most important things to do with trailer tires is to make sure that you are running the maximum psi that is listed on the tire. This will allow that tire to handle the maximum load capacity that it is rated for. The overall diameter on your 20.5 x 8 -10 tires is 20-1/2 inches and if it is a load range C tire, the load capacity would be 1,100 lbs at 50 psi. The smallest 13 inch trailer tire size is 175/80-13 and it has an overall diameter of 24.1. That will be a difference...

You would need to have them mounted at a local shop upon arrival. The # AM22318HWT is a 4 on 4. If you need a 5-bolt wheel, the # LH45FR would work instead of the # AM22318HWT.
