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"

Purchased a new set of tires for my 22 ft enclosed cargo trailer. Moved from west coast to Midwest hometown. After several trips, the tries performance was flawless. Highly recommend! Thanks.


Our next trip is coming up fast so the quick ship time was very much appreciated. I've already installed the tires on our camper and they look great. The Rims are made in the USA.



Still very happy with these tires and rims. I cleaned the rims last weekend and they still look great.


I bought this as a spare tire for my trailer and it is an exact match both tire and rim of whats on the there now. It showed up sooner than expected and even the packaging was in good condition. I have been dealing with Etrailer for about ten years and have no plans on changing!


Parts arrived on time in great shape everything went together like dream no problems my trailer looks great and I know it will be easer to maintain, the info on the web site was great with having the bearings in hand picking the correct hubs was easy with them listed with the hubs.
Thank you for having great info to make finding what a person needs.


Tires came on time as sales said. So far a good looking tire and rim. Tires have a deep thread.


Arrived on time with no damage from carrier one year later being out in the elements the whole time, no rust or paint chipping off of cheaper 4 white wheels been on very rough terrain no flats. Took on about 18 trips so far this year about 4,000 miles. Very pleased.


I asked if the tires were balanced when I ordered them,and I was told they were, but they may need to be balanced again due to handling. There were no balance weights on any of the wheels. You draw your own conclusion whether (true or false statements) were made.

Etrailer Expert

Jenny N.


The wheel and tire combos we have are not balanced from the manufacturer. What they do when the tire is mounted to the wheel is match the high [heavy] spot on the wheel to thw low [light] spot on the tire. This does leave the wheel and tire somewhat balanced. You can have the tire professionally balanced if you want once you receive them, but having perfectly balanced tires is not as important with trailer tires as it is with a passenger vehicles.


This product looks great! Very well made. I am using it as a spare tire for my trailer because it did not come with one when I bought it. Delivery was on time and fast.


Got here sooner than expected ty to the agent for helping me switch my order to get faster shipping will definitely recommend


I had a great experience with the customer service team. The gentleman assisting me was extremely knowledge and guided me to the correct tire for my boat trailer


I bought these tires and wheels for my abused, manure trailer. The old ones were rusty and had uneven wear on the tires. Plus, they are pretty old and dry rotten. I like the simplicity of ordering tires and wheels online and having them delivered right to my garage door. Well packaged, good price and even set to the proper air pressure! Thank you.


Package arrived sooner and better than expected etrailer always a win


Great product, fit just as it should. Will buy again. Put them on a 32 foot Brook side travel


Great set of tires and wheels looks good but most of all matched set for my trailer and feels safer than different tire on each hub that came off cars that were used tires and already worn out before they were put on the trailer. 2 blow outs on this trip. That did it. I bought 4 new tires and rims and now no worry about safety. What a good feeling!


Wheel arrived on schedule and in goos solid wheel box for shipping damage protection.
Will order again through trailer as needed.


I had ordered this, and got a error part, but they fixed it immediately. I do much business with them & it was the first mistake ever. These people are awesome!


very informative website. Super fast order! got here in two days! everything was perfect! I would highly recommend them!


Recevied tires in great shape. Installed om my trailer very easily. They look great on our trailer.


Purchased four Kenda Karrier Steel Tires and Wheels for our horse trailer. They are great! And etrailer provided excellent customer service! My mechanic had me order one set of four, only to find out that our trailer has mobile home axles, so we had to return the first set of four and order a different set. Their customer service made that super easy, and they refunded for the first set promptly. On both orders their shipping was quick too. Service doesn't get much better than this!


Great price. Fast shipping!


I ordered these wheels and tires for a 31 foot bumper-pull camper and they were delivered on time. I checked the dates on the tires and all 4 had very recent manufacture dates. Tires were mounted and inflated, but were not up to the recommended pressure for the load. It's not a big deal to air them up a little more and you should check your tire pressures before every trip anyway. I just added this info to let people know that you can't just throw them on and go.


Much better tire than the factory tire. Sturdy rim, and good looking tire with good tread. Tire came fairly fast. Was here within a week from ordering.


Tires (3) were shipped SUPER fast. Tires were mounted well and aired to running pressure already. They were good quality at a great price.


These wheels/tires are for our High School Marching Band trailer so we have a lot riding on them. I did the research on the product before searching for a vendor and 2 coworkers recommended Your website was easy to navigate, you had the product I needed at the best price, shipping was free and the wheels arrived in a few short days in perfect condition. My experience could not have been any better from start to finish and I won't be looking any further than etrailer for anything else our band requires. Thank you.


Tammie was amazing and provided me with customer service that went above and beyond. I'm super happy with how the order went, and how quickly the tires were delivered via UPS. Thank you, Tammie!

  • Recommendation for a Tire for Use on Portable Dock to Ease Removing Dock from Lake
    You have a few different options to help you with removing your home-made lake dock from the water. One is to use a winch. The linked article explains the various types of hand winches available and if you have a place to mount one (such as on a vehicle, ATV or fixed mounting point near your dock) a winch will take most of the burden off you as you pull the wheeled dock out of the water. I also included a link to our main page for winches. Another option is to add a second wheel/tire to...

  • Are Tire & Wheel Combos Balanced at Factory
    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 FAQ article.

    An ST225/75R15 trailer tire like the Kenda Karrier # AM10256 that you're looking at will fit a 15 inch wheel that has a 6, 6-1/2, or 7 inch width. Your existing 265/75R15 size tires are compatible with 15 inch wheels that have a width of between 7-9 inches. This means there's a chance the smaller tire will fit your existing wheel but only if it has a 7 inch width. It's more likely though that what you have is too wide to allow for a proper mount.

  • Replacement Wheel and Tire Combo for 1994 Four Winns Boat Trailer
    Although the Loadstar Wheel and Tire Combo you referenced, part # AM3S870 would work well for you, had you considered going with the radial equivalent, part # AM32664? Both the bias-ply and the radial are rated at 2,540 lbs per tire. Radial tires generally run cooler, which will lead to longer tire life. For maximum tire life, be sure to keep tires inflated to the maximum psi as recommended by the tire manufacturer, which in the case of these tires is 65psi.
