Bias Tires vs. Radial Tires

Bias vs. radial tire graphic

Bias ply tires are designed for off-road or agricultural applications. They are built with thick, durable nylon cords that are positioned at a 30- to 45-degree angle to the direction of travel. The layers alternate in a crisscross pattern, making the sidewalls stiffer so that the entire tire is able to flex easily. As a result, the tire provides a smooth ride and improved handling when trailering on uneven surfaces.


Beveled Stud Holes

Beveled Stud Holes Front and Back

The stud holes on this steel wheel are beveled to ensure that the wheel stays tight against your trailer hub. This also eliminates the need to constantly retorque the lug nuts.


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"

I put these tires on a two horse bumper pull trailer when we moved across the country last year. I had a lot riding on them literally and figuratively as we loaded up our horses in the middle of the summer to move and had these tires failed, we may have been stuck on the side of the road in 95 degree weather with live animals that would overheat quickly. Despite going through states with poor road maintenance and a couple thousand miles out on them on their main voyage, they functioned just I had hoped and still looked brand new after. All good since then as well, however we don’t use the trailer often or for long distances at the moment.

I ordered the 2 Tires Monday afternoon and they were shipped Monday. I received the tires on Thursday and realized that I had ordered the incorrect hole pattern. I email Etrailer.com and they sent me return labels. The return shipping cost was taken out of my credit issued. I liked the tires and wheels very much so I reordered the correct size and ordered 4 more for another larger trailer.

Tires are holding up very well. Took a 500 mile trip with no problems. Put a lot of weight on the trailer, but it pulled very well, great tires for the price.

Tire and rim were shipped promptly and is an exact match for my tires and rims on my 2006 Sunnybrook camper. Reasonable price included shipping. My tire had shredded so I elected to get a tire and rim combo after having to use the spare to complete a trip. Customer communication was excellent and I am very happy with my purchase. Thank you!

A year ago, I ordered a set of (4) wheels and tires since I shredded an old tire on the way home one day, and my wheels on my second-hand trailer were rusted and did not match. Delivery was prompt, exactly as expected, and I am thoroughly satisfied with my purchase one year later. My trailer was once a "landscape" trailer and has faded, powdery blue paint which rubs off on you if you brush up against it. The new wheels and tires look fantastic and probably doubled the value of my trailer of twenty years and have certainly gotten my $$'s worth out of. I am now ordering new wiring and other trailer accessories from etrailer since I had such a great experience with them before, and I intend on keeping this ugly old trailer. etrailer has had my past business, they have my current business, and will have my future business as well.

It was a great shopping experience, even knowing I could have gone to a tire dealer I didn't think I could beat the price, and with free shipping it was a no brainer. Tire and wheel arrived yesterday, 3 days earlier than anticipated. Thanks for a great online shopping experience!

I am very impressed with this website. A few weeks ago, I had a tire blow out on my 10K 6'x12' dump trailer when I had 3 tons of wood pellets on it on my way home. As soon as the old tire blew I pulled over and changed it out. I found the old tire and rim was destroyed. I searched locally for a new tire and rim for my trailer. I found that Les Schwabb's price for a rim and tire was $250 and the tire was very poor quality. I searched the web and found etrailer. I found the tire and rim I needed quickly and I also found it for about $100 dollars cheaper than Les Schwabb. I could not believe how expensive Les Schwabb was and how much they charged for a simple trailer tire and rim. I am very happy with the new trailer tire and rim I got from etrailer and I will continue to do business with etrailer from now on when I need things for my trailer. The trailer tire and rim from etrailer was much better quality than Less Schwabb. Definitely don't buy anything from Les Schwabb as they are a total rip off and greedy!

I have been running these Loadstar K550's for years and they are good tires. I have used them on everything from utility trailers, RV's, boat trailers ect..... Great value and performance.

I saw the reviews on this wheel and tire and feel that it will do exactly what I need when the time comes I have a blowout on the highway and need to use this. As always with my orders from etrailer, they have shipped in a timely manner and they care about customers feedback to help manage there products they carry. I would recommend them to anyone with trailer needs

Tires shipped to my door packaged well and damage free. Solid set of tires and clean new rim. Purchased these to put on a 20 foot box trailer. We didn't get a spare with the trailer purchase so luckily, I now have two for a great price compared to local dealers and suppliers.

Ask the Experts about this Kenda Trailer Tires and Wheels

  • Does Loadstar # AM3S870 Tire and Wheel Come Balanced
    The tire and wheel combos that we have available, including the Loadstar ST225/75D15 Bias Trailer Tire with 15" White Wheel # AM3S870 that you referenced, do not come balanced like a standard passenger vehicle tire and wheel would be balanced at a tire shop. What the manufacturer does though is match the tire's heavy spot with the wheel's light spot when mounting them. This is a type of balancing that is sufficient for a trailer tire and there is no reason you would need to have them machined...

  • 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.

  • Recommend Replacement Trailer Tire For 7.00-15 Tire On 1961 Airstream Trailer
    For an exact replacement tire for your 700-15 tire, we have the Kenda Tire, part # AM10414, which is 7.00-15 tire. Since the LT on this tire is after the tire size, it indicates that the tire can be used as a light truck or trailer tire. The overall diameter of part # AM10414 is 29.3 inches and is a load range E tire which is rated at 2,376 lbs at tire maximum PSI. The item you selected, Kenda Tire, part # AM3S870, with a tire size of ST225/75D15, will be a little shorter of a tire,...

  • Recommended Spare Tire for a Venture VATB-7225 Boat Trailer
    You will want to get a spare tire that has the same size and weight capacity as your current tires do. If your spare was rated for a lower weight capacity and you had a blowout while under a full load, your spare tire might not be able to handle the weight. I looked up your Venture Boat Trailer model and it looks like your tire size for your VATB-7225 is ST225/75D15 with a Load Range of D. From what I gather it looks like your wheel has a 6 lug pattern. A great spare tire would be the...

  • Do Trailer Tires/Wheels Need to Be Balanced?
    Our trailer tire and wheel combinations, such as the Loadstar # AM3S870 you referenced, do not come balanced like automotive tires do. 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. This leaves the wheel and tire adequately balanced for trailers. You may have the tire/wheel professionally balanced if you wish, but having perfectly balanced tires is not as important with trailer tires as it is with passenger vehicles....

  • Recommended Air Pressure on Trailer Tires That Are Not Loaded to The Maximum Load Capacity
    We always recommend to run the maximum air pressure stated on the sidewall of the tire. That is the safest thing to do because then you have the maximum weight capacity covered for any type of load you will be hauling. On the Kenda Tire and Wheel Assembly, part # AM3S870, you have referenced, the maximum load capacity for the ST225/75D15 tire is 2,540 lbs at 65 psi. You can lower the air pressure in your tires, but that will lower the weight capacity of that tire. That would work...

  • How To Change To Smaller Wheel and Tires on Utility Trailer With 6-Lug 15 Inch Wheels
    If the hub on your trailer has a 6-lug bolt pattern, the smallest tire size that will fit is the 15 inch tire size. There are no wheels smaller than 15 inch with a 6-lug bolt pattern. You will need to change out the hubs on the axle to a bolt pattern like the 5 on 4-1/2 inch size to be able to use a smaller wheel and tire. To change out the hubs we would need the inner and outer bearing part numbers and the seal part number from your existing hub to select a hub with a 5 on 4-1/2 inch...

  • Trailer Tire Age and Methods to Prolong Tire Life
    Trailer tires made overseas are usually at least 6 months old by the time they are fabricated, shipped via ocean container ship to a distributor here in the USA and reach our temperature-controlled warehouse. It is safe to say that you will not find us shipping a tire much "younger" than 6 months old. It is also likely that the very oldest a tire would be when we ship it, meaning a tire that is not among the most common and popular sizes that we ship every day, is about 2 years. I went...

  • Lowering the Deck of a Car Hauler By Going to Smaller Tire/Wheel for Lowered Car Loading
    Going to a smaller wheel and tire would definitely put your trailer closer to the ground which could make your low race car easier to load. The current diameter of the tires you currently have is 26.3 inches whereas the size you are considering, 185/80-13 has a diameter of 24.4 inches. Hopefully your trailer has hubs with a bolt pattern of 5 on 4-1/2 inches because that is the only bolt pattern wheel we carry that is compatible with the 185/80-13 size you are interested in.

  • Looking For 5-1/2 Inch Wide Wheel for 7.00-15 Trailer Tire
    The narrowest 15 inch wheel we offer with a 6-on-5-1/2 inch bolt pattern is a 6 inch width. We don't offer a pre-mounted tire and wheel combo, but you could use a basic white spoke wheel like the # AM20532 and purchase a 7.00-15 load range E tire (2403 lb capacity) as part # AM10414 or a load range D (2156 lb capacity) as part # AM10412 and have them mounted locally. Typically, you'd want all your wheels to be the same size, but using a 1/2 inch wider wheel as a temporary spare...

  • Are Bias Tires Okay for Highway Use
    Yes, you can definitely use bias tires, like part # AM3S870 you looked at, on the highway. Bias tires weren't really designed for off-road use per se but they are better for it. Likewise radials are better for highway use than bias tires and you'll likely get more life out of them. But either work for either application. Bias tires were actually much more common on all trailers for quite some time because the cost of radials was a lot higher. Now that the prices are closer to the...

    Changing the hubs on your trailer would depend on the spindle size. You can remove your hub and look for the bearing and race numbers.

If you cannot find the numbers you can use a digital caliper like part # PTW80157 and measure your spindles in the places noted in the drawing I have attached.

    We do have options for replacing your tire and wheel. We don't sell used tires and wheels, but the modern equivalent of the 7.00-15 tires are here. They are in fact 225/75D15. A good combination wheel and tire is the Loadstar Bias White Wheel, part # AM3S870. This wheel has the same 6 on 5-1/2" bolt pattern and is a 15" rim. The load range is D, and the ply rating is 8 (so slightly higher than your original tire). I've linked to a video review of this tire for you to look at.
