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.

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"

Bias tire has a ply rating of 6 and a 1,820-lb maximum load at 50 psi. The 15" diameter x 5" wide steel trailer wheel features a 5 on 5 bolt pattern and a corrosion-resistant powder coat finish.


Excellent experience. After being in a jam over the weekend with a blow out, I needed the correct tire and wheel. These were for a Big Tex utility trailer with 5 on 5 which is impossible to find at retailers in my town. I ordered a pair on Monday and had them by Wednesday noon. They were shipped in their own box. I would highly recommend buying from this company and will use them for future items I need. Excellent customer experience.


Bought a used UTV that came with a single axle trailer & the trailer had no spare. Got a quote from a local tire store that the spare would cost about $250. Found the same wheel & tire on eTrailer for half the price with free shipping. I'm a happy customer!


The product purchased was Loadstar ST205/75D15 Bias Trailer Tire with 15" White Wheel - 5 on 5 - Load Range C. The delivery was free. The choice of products on was greater that of local brick and mortars stores and I did not have to spend a lot of time driving around looking for a replacement. The tire/wheel was well packaged. Upon opening, the product met all expectation; it seems to be a quality product. The price was acceptable. When the occasion arises, I will shop again.


Good service from etrailer. Customer service was great. I ordered the wrong size wheel in the beginning. Lori was very polite and helpful in getting the right size ordered for me. Good company to do business with.


Impeccable service I have great respect for people who do what they say and say what they do you have restored my confidence in on line shopping. I will highiy recommend to anybody. I haven't seen this good of service in a long time. Thank you


The order was promptly filled and arrived quickly. They also provided tracking during shipment which was helpful. Very pleased!


I have never been disappointed with etrailer! Communication is awesome, delivery dependable, and products are first class.
I highly recommend this company!


this was a very...very... very fast turn around...unable to find the bolt pattern in my area...e-trailer had what I very much needed


I haven’t got to install them, but they look very nice. They’ll make my trailer look fantastic.


ON time shipping, installed easily and are doing great, trailer rides so much better


This was a very easy purchase for me. The wheels and tires were exactly as I ordered. The delivery was faster than I expected. I am very happy and will consider e-trailer again in the future.
Alyssa M did a great job for me. I thank her.

perfect, I am very happy

The product was exactly what I ordered. It is of good quality and the delivery time is very quick.


As always; Good product, Good price and GREAT service! Thank You!!


Trailer wheel and tire were easily ordered with the help of customer service rep Shawnee. Product shipped quickly and arrived on time and was exactly what I wanted. The shipping was free and the product price very reasonable. Thanks!


easy to order, excellent communication and delivery.


Very satisfied with the product


On time and just what I ordered very importaint as we are a MFG.


Wheel fits perfectly. Bought it for a spare for the trailer. It's a 15 inch 5 lug 5 in unit. The shipping was super fast. Ordered on a Wednesday late at night and it was delivered in less than 48 hrs.


Service was great and delivery was quick. Just what I needed at a great price.


They shipped quickly. I intend to use this as a spare so compared to my last one which i didn't have this is 100% better. But the tire and rim look great no damages or issues.

  • Can Changing From Bias Ply to Radial Trailer Tires Contribute to Trailer Sway
    There can be many factors that lead to trailer sway. In this case, the new tires have a lower load rating. If they are being overloaded, that could cause some problems. You will also want to make sure they are inflated to their maximum rated psi as indicated on the tire sidewall. Radial tires trend to track better than bias ply tires so I do not think the different style is leading to the problem. If the tires are a different size than what was on the trailer, that could lead to a difference...

    Yes, we can help you select a correct spare tire/wheel for your 5 x 8 enclosed trailer.

We offer tire and wheels by themselves, and also already mounted together. Tire size will be indicated on the sidewall and might be for example 205/65-10. You also need to match your wheel bolt pattern. In addition to the helpful articles I have...

  • Can Trailer Tires Exceed 65 Miles Per Hour
    I can't recommend you exceed the speed rating of a trailer tire. Doing so will cause the tire to heat up considerably and fail much easier. My sister used to exceed the 65 MPH speed rating of her horse trailer tires and wondered why she kept having blowouts. She finally slowed down and her tires stopped failing. I attached a help article on trailer tires for you to check out as well.

  • Trailer Rim Availability that Will fit a 5 on 5 inch Bolt Pattern
    A trailer wheel with a 5 on 5 inch bolt pattern like the # AM3S638 would bolt up to a hub with a 5 on 5 inch bolt pattern. However, I can't recommend you use a trailer rim and tire on a vehicle unless the hub happens to be on a truck bed that is converted to a trailer.

  • Difference Between Trailer Tire Size that Has a Letter D and Letter R
    The difference between the two trailer tire sizes is that the letter D in the first size you listed ST205/75D15 stands for bias ply and the letter R in the tire size that they put on your vehicle stands for radial. Radial tires are preferred over bias ply, but if the rest of your tires are bias ply and now you have a single radial you would want to strongly consider having all tires match. The main difference between a radial ply and a bias ply tire is how the tire is constructed. The...

  • Will a 205/75-15 Trailer Tire Fit the Same Wheel as a 225/75-15 Tire
    Every trailer tire can fit a range of different wheel widths. If the wheels you have are 6 to 6-1/2 inches wide (on the inside where the tire sits, not overall width) then yes, you can put a 205/75 on in place of a 225/75. The 6 and 6-1/2 widths are the 2 sizes that overlap between those 2 tires sizes.

  • Does Trailer Tire Weight Carrying Capacity Decrease with Less Air in the Tires
    Tire capacity will vary by size but for a 205/75-15 Load Range D it will be a max of 2,150 pounds at 65 psi. Trailer tires should be ran at the max psi to avoid overheating the tire. If you run it at 50 psi the capacity per tire decreases to about 1,600 pounds per tire but it is hard to say for sure due to environmental factors, tire condition, and so on.

  • Can 185/80R13 Tire Be Replaced With 165/80D13 Tires On Small Camper
    If the wheels on your camper can work with the smaller tire you should have no problem. The diameter of the 185/80R13 tire has an overall diameter of about 24.65 inches. The 165/80D13 tire will have an overall diameter of about 23.40 inches, so it will be a little over an inch shorter than the tires you have on your camper now. You are talking about replacing radial tires with a bias-ply tire. Radial tires flex more than bias-ply and will typically run cooler than a bias-ply. You always...

  • Why Does Trailer Tire Have Lower Weight Capacity When Used in Dually Setup
    This is a really good question that has come up before. I spoke with our local tire guru here at etrailer about this a while back and he offered the following explanation for the difference in tire capacity when a tire is used as a dually or single wheel setup: The load on each tire in a dual tire system is never the same. Tires can be worn differently, if wear is different the overall diameter will be different and the larger tire will carry more load. Also the inner tire can be more...

    In the 2 measurements you've provided, the 15 is the designation for the wheel size that those 2 particular tires will fit on; in tire measurements, usually the last number corresponds with the diameter of the wheel a particular tire will fit on. So, in both of these cases, you would need a 15" wheel. For the 7.00-15 tire, those would fit on 5", 5-1/2" and 6" wide wheels where a 205/75/15 tire will fit on 5" to 6-1/2" wide wheels. The one thing I noticed in those measurements is that you're...

  • Can I Use a Bias-Ply Tire as a Spare on a Trailer with Radial Tires
    It is not recommended that you use a bias ply tire on a trailer that has radial tires. Due to the different constructions of either tire the ride will be different on each wheel and would most likely cause sway that could be hazardous to you and other motorists. The main difference between a radial ply and bias ply tire is how the tire is constructed. The cords underneath the tire are run in different directions. On a bias tire, the cords run at a 32 degree angle from the direction of...

    I think you are confusing the tire size numbers with load range. This size tire is available as a ST205/75-D15 or as a ST205/75-R15. The D indicates that the tire is a diagonal bias ply construction and the R indicates that the tire is a radial tire construction. Beyond the size and type, there are load ranges for tires. Most trailer tires are load range B, C or D. This number indicates how much weight the tire can bear at a certain inflation pressure. The tire and wheel combo you were...

If it's 2-3/4 inches, its 5 on 4-3/4.

  • Can ST205/75D15 Tires Replace ST205/75R15 Tires On Camper Trailer?
    Yes, ST205/75D15 tires would be able to replace your ST205/75R15 tires as they are the exact same size, with the only difference being the D tires are a bias ply, and the R tires are a radial. I recommend sticking with a radial tire like the Karrier ST205/75R15 Radial Trailer Tire - Load Range D # AM10245 as they are going to give you better on-road traction due to the design of the sideway, and will stay cooler on the highway leading to longer tire life.

    The closes tire and wheel combo we carry to your 205/75-14 tire size and wheel that has a 5 on 5 bolt pattern is a 205/75-15 like part # AM3S638. Going up in size the overall diameter is an inch larger and it's the same width. You need to make sure you have clearance between the tire tread and the underside of your fenders. You want about 4 inches if possible. With that bolt pattern I'm guessing this is an off-road trailer so the tire I recommended is a bias ply. They're better for off...

  • Will Higher Ply Rated Tires Stop Trailer Sway
    The ply rating of a given tire size is going to depend on the load range of the tire. Tire # AM3S638 for example is a load range C so it has a ply rating of 6. A lower load range in the same size would have a lower ply rating. By comparison an ST225/75R15 tire in load range E, # AM10303, has a ply rating of 10. Bias ply tires will have a stiffer sidewall compared to their radial counterparts. The tires are likely not going to help much with sway. If you are using a single friction sway...
