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"

Still rolling after a year on the flatbed trailer. Just what I asked for and delivered in good time and condition


Needed a spare tire and wheel for my boat trailer and has a great selection with lots of option from standard to completely custom. High quality products and competitive prices will keep me coming back for all my trailer needs.


Fast delivery , all ready to put on & roll up the highway !



Great !

@Robert We're glad to hear that you're still happy with your purchase!


Fast, FAST shipping. Tires were just as described and good quality!


Order arrived on time and was the quality I expected. Thank you E Trailer


Spare tire was delivered for free and quickly and as described.


I bought this tire for a spare for our travel trailer so needless o say I haven't actually used this tire and wheel. The wheel is made in the US and tire is made in Taiwan, they both look really good and I hope will do the job if needed.


I bought this for a spare tire for my camper. Good, strong tire and rim.


This was a good deal on wheel and tire combination to replace the old ones on my flatbed trailer. One of wheels had a minor dent on the rim but shouldn't affect the sealing of the tire. Something happened in shipping most likely. Always happy with etrailer products which is why I keep coming back. Good quality and pricing and information about the product.


High quality RV spare tire!


Arrived quickly fit perfectly great com[any to deal with Thats why im a repeat customer, thank you


I ordered trailer tires mounted on rims just before Christmas and they arrived within the week. Decent tires and a good price. The boxes look like they could be used to return the items had that been necessary. Exactly as advertised. Great service. I would highly recommend them.


Natalie answered my call for help, She asked me when do you need the tire and wheel? I replied "yesterday" ! She said OK!
Then she said they would send it free shipping! I said lets do that! I placed this order on Monday morning, I received it on Wednesday late afternoon! THIS WEEK!
These people are absolutely AMAZING!
The day before I had a blowout on my portable emergency back-up generator. My tire and wheel was destroyed! I had it towed to my friends shop. I called my friends at Associated Power in Wilmington CA," Greg" recommended
I did, they saved my life!
I highly recommend them and I am now they're newest good will ambassador.
They are good, friendly down home good people.
Thanks, Natalie !!!!!!


Good product and value


My used Airstream Bambi did not come with a spare included. I purchased the wheel/tire as an emergency spare. This proved to be a prescient action as my first time out following the purchase resulted in a flat. The spare was a completely compatible and serviceable temporary replacement. Beyond what has been only a one time use, I cannot comment on the long term service of this item.


Tire and wheel delivered on scheduled day, product was what I anticipated. Mike who took the order very very professional and helpful.


Great tire and wheel


Great price. Shipping was really quick. Tires/wheels were in great shape when they arrived.


The new tires and wheels are on and look Great ! We will feel a lot more comfortable when we leave this Texas Heat and head to Colorado for a month or maybe more.


Bought this as spare for my dual axle boat trailer. Used it when an OEM tire suffered a total failure/explosion on I95 at 70 mph! Thankful to have had this.


It is exactly what I ordered and the shipping was very timely.


Great for a spare tire setup,affordable with the e rated tire and mounted on a new wheel.
Kenda is better rated than many import tire brands so its fine for just a spare.


I haven't been able to utilize this new spare yet (a good thing) but it seems to be a good tire and rim. Shipping was fast and easy.


Ordering a spare tire for my camper could not have been easier. etrailer had the right tire I needed for a great price plus unbelievable free shipping.


Very satisfied!!

  • Offset of the Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel # AM32680
    Nearly all trailer wheels including the Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel # AM32680 have a zero offset as that helps the wheel distribute the weight of the trailer evenly on either side of the wheel.

  • Recommended Spare Tire for an Airstream Travel Trailer That has 6 Lug Wheels
    The Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel # AM32680 will definitely be a good option for a spare. There is really only one bolt pattern used for 6 lug wheels on trailers, and Airstream follows that standard when they use them. Though I could not find a standard used for the tire size, this is a pretty common one so that should be good as well. With this also being a Load Range E, it is rated to 2,830 pounds at 80 psi so it should cover whatever you can throw at it.

  • Trailer Wheel and Tire Recommendation for 6 on 5-1/2 inch Bolt Pattern and Zero Offset
    Since you said you have a bolt pattern of 6 on 5-1/2 inch the smallest wheel diameter we are going to have is the 15", for that I have the Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel - 6 on 5-1/2" - Load Range E, Item # AM32680 which will work great. It has a zero offset as well. Since this is a larger wheel diameter it would require you to go with a new tire as well so that's why the part number I mentioned includes a tire.

  • Advisability of Increasing Tire Size and Tire Load Rating on Utility Trailer
    The general rule of thumb is that you'll want at least three inches of bump clearance with the trailer at full load. The 225/75-15 tire is about 2 inches larger in diameter than the 205/75-14 tire you're currently using. Using the larger tire will move the tire one inch closer to the fender, so in my opinion going with a larger tire size wouldn't be a good idea unless raising the fender is possible. Also, keep in mind that going with a larger tire with a higher load rating won't necessarily...

  • Information Needed to Add Electric Trailer Brakes to a Trailer
    I am sure we have all of the parts you would need to add brakes to your trailer, but we first need to determine what you have on your trailer so that we can get the right components. I attached a help article that covers the entire process for you to check out, but basically we have to first determine what spindle you have on your trailer so that we can pick out the correct hub/drums and then pick out the correct brake assemblies based on that. You will have to pull a hub off your trailer...

  • What Capacity Tire is Needed for Tandem Axle Trailer that weighs 10,000 lbs
    If your trailer tires are not rated for the total amount of weight your trailer is going to be towing you are asking for problems. The part # AM32680 that you referenced has a capacity of 2,830 lbs and would give you more than enough capacity. If you are interested in replacing your wheels and tires to something that will be rated high enough this would be the way to go.

  • Valve Stem Material On Americana Tire Wheel Combo
    The valve stems used on the Americana ST225/75R15 Radial Tire, part # AM32680, are constructed of steel reinforced rubber and rated up to 100 psi. Steel valve stems are recommended when buying tires that have a requirement over 100 psi, so with the psi for this tire at 80, you should have no problem with the valve stems.

  • Is # AM32680 Wheel Tire Combo Balanced
    Because trailer axles do not steer, it is nowhere as crucial that trailer tires be balanced. On a passenger vehicle, the vibration caused by an out of balance tire is immediately evident. For a trailer, most people wouldn't notice it. 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. This works very...

  • Origin for Kenda Karrier ST225/75R15 Radial Tire with 15-Inch White Spoke Wheel # AM32680

  • Where is the Date Code Located on a Trailer Tire
    The date code on a tire is a 4 digit code stamped somewhere with the other information on the sidewall of a tire. I included a picture showing what to look for. The first 2 numbers are the week and the second 2 numbers are the year. In the picture I included the code is 2511 meaning that tire was produced in the 25th week of 2011. This is obviously an older picture since we would not have tires that old still on the shelves.

  • Are Trailer Tires Still Limited to 65 MPH
    At one point if there was no speed rating listed on a trailer tire you'd have to assume that the speed limit was 65 mph. But what we have seen in recent years is trailer tires increase the speed ratings as customer really do want to be able to travel faster than that so most options are now higher rated. For example the part # AM32680 that you referenced has now the most common higher rating of 81 mph.

  • Will Incorrect Tire Inflation Pressure Affect Handling from Grand Design Reflection 28BH 5th Wheel
    If you were running your new special trailer tires a full 30-psi below their rated (and required) 110-psi inflation pressure then that is probably the cause for the degraded handling from your Grand Design Reflection trailer. Special trailer tires, the ST-type, must ALWAYS be inflated to their maximum COLD psi pressure as noted on the tire sidewall. It is never appropriate to under- or over-inflate a trailer tire for any reason; there is no benefit to doing so and this can cause loss of...

  • Correct Tire Pressure for Kenda Karrier ST225/75R15 Load Range E Tires
    Kenda recommends keeping the 225/75-15 Load Range E tires used on their # AM32680 wheel/tire combo fully inflated to the 80 psi listed on the tire sidewall, because the capacity of the tire is dependent on the air pressure. Some manufacturers, notably Goodyear with their Endurance trailer tires, has load tested their tires over several different air pressure levels, so at a given pressure the tire's capacity is known. Kenda only tests them at the maximum so if you were to run the tires...

  • How Many PSI Should the Karrier Radial Tire and Wheel Part # AM32680 Be Filled To
    I looked up your order info and saw you had purchased the Karrier ST225/75R15 Radial Tire with 15" White Spoke Wheel part # AM32680. The tire that comes with this combo will need to be filled to 80 psi while cold no matter if the trailer is loaded or not. This will ensure you are always receiving the full weight capacity and performance of the tire. It has a 65 mph speed rating as you mentioned and you will need to abide by this rating to prevent blowouts.

  • Will Wheel and Tire Combo part # AM32680 Work Well on 2010 Keystone Cougar 276RLS
    If your current tire size has the capacity needed for your towing setup there really isn't a need to go with a Load Range above it. If you are experiencing wear issues most likely that has to do with the inflation of the tires. Are they inflated to the max psi listed on the sidewall? They have to kept at this pressure at all times otherwise you lose capacity and have wear issues. That being said, if you have a 6 on 5-1/2 inch bolt pattern the part # AM32680 would work great on your trailer.

  • Can a Trailer with 205/75R14 Tires go to 225/75R15 Tires
    Your current tires that are 205/75R14 are 26.3 inches in overall height. The 225/75R15 you are considering is 28.4 inches in height. So that means that the new tires would take up about an inch more of your fender wells. If you have clearance for that you should be just fine. You will have to have a 6 on 5-1/2 inch bolt pattern to fit the Load Range E rim and tire part # AM32680 though. I attached a help article on bolt patterns for you to check out as well.
