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"

I could not find this trailer tire and wheel in my size at any of my local suppliers. They also could not give me a date of when they might get restocked.

I am so happy I found your web site , I got my delivery in 5 days shipped in a box to prevent any damage. Great place to shop. 881500

- AM3S638

I got 4 wheels to replace my original trailer wheels which had lasted for 16 years. These new wheels arrived very quickly and fit properly, the web site had all the info I needed to make sure I was able to order the correct size (bolt spacing). I haven't driven the trailer yet, and obviously not enough time has passed to say how well these tires will wear and how long they will last. I need to update this review every 5 years or so.. (I put very few miles on my trailer) 786736

- AM3S638

Very nice tire and wheel. 785150

- AM3S638

After a year, the tires are performing as expected. They are on a dump trailer that gets occasional use. The service from etrailer was good. After an error in shipping one of the 4 mounted wheels and tires with the wrong bolt pattern, they quickly sent the right one and picked up the wrong one. thanks 782015

- AM3S638

Great service 779582

- AM3S638

The product was as stated in bolt on ready to go shape! Only gripe I'd have is the fact some trailers still use an 8" rim and out of all the rim or rim/tire combos-i cant get an 8"rim. I bought 1 locally 2 years ago out of a hardware store and now cant seem to find one anywhere?? so I had no choice currently but to buy the 6"rim/tire package 774450

Ask the Experts about this Kenda Trailer Tires and Wheels

  • 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...

  • 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...

  • 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.

  • How to Determine 5 Lug Bolt Pattern of Trailer Wheel
    To measure a 5-bolt lug pattern you measure from the center of a bolt hole straight across the center of the wheel to right between two lugs on other side. OR the way I prefer is to measure from the center of a bolt hole to the outside edge of either of the bolt holes furthest from it. This will get you the same measurement. I attached two pictures that show this as well. Since you mentione 4-1/2 inch you most likely have the very popular bolt pattern of 5 on 4-1/2 inch since this is...

  • What does the D15 Mean in Tire Size ST205/75-D15
    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...

  • 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...

  • 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....

  • 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.

  • 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...

  • 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...

  • 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.

  • Inexpensive Replacement Trailer Rim that is 15 x 6 inches and has a 5 on 4-1/2 Bolt Pattern
    An economical option that is 15 inches in diameter, 6 inches in width, and has a 5 on 4-1/2 inch bolt pattern is the part # AM20522. For a 205/75R15 tire you would want the part # AM10245, for a 225/75R15 you would want the part # AM10303. To determine which tire size you would need you will want to check the tire size that is stamped on the sidewall of your tire.

    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...

    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.
