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"

  • Wider Trailer Tire Replacement for 4.80x12 Tires
    In order to replace 4.80x12 tires you have quite a few options but the widest option for this is going to be based on the available space you have. The 4.80x12 tires are 4.9" wide so if you are looking for a wider option, I recommend a 215/75-14 which is 8.4" wide. That said, the 215/75-14 is 26.3" diameter and the 5.80x12 is 20.7" diameter so you need to make sure you have the extra space needed. I recommend 3-4" between the top of the tire and bottom of the fender and 1" between the inside...

  • How To Confirm Wheel Bolt Pattern for 215/75-14 Tire and Wheel
    The Karrier ST215/75R14 Radial Trailer Tire with 14" White Wheel part # AM32181 is a great option and what I recommend for replacement. In order to confirm this is correct you'll need to verify the bolt pattern by measuring the lug studs. The lugs studs will need to be measured from the center of any stud to the point halfway between the studs directly across from the first or you can measure the two studs next to each other. If the two studs next to each other measure 2-5/8" then it's...

  • ST215/75/14 Spare Tire and Wheel Recommendation
    Based on the information you gave the Loadstar ST215/75D14 Bias Trailer Tire with 14" White Wheel # AM3S550 that you referenced would be a great spare for your trailer. Most likely you do have a 5 on 4-1/2 inch bolt pattern. I attached an FAQ article on determining bolt patterns for you to check out as well.

  • Using Bias-Ply Tire as a Spare Tire on Trailer With Radial Tires
    It's recommended that all tires used on a trailer are of the same type, either all radials or all bias-ply for the best performance. Radial tires have more flexible sidewalls, mixing the tires can cause handling problems. If a bias-ply was used strictly as an emergency spare and was immediately replaced as soon as the radial was fixed you'd be ok, but the best practice is to keep your spare rotated with the other two tires. Using a # AM32181 ST215/75R-14 radial tire as a spare would...

  • Do Trailer Tire and Wheel Combinations Come Balanced
    The wheel and tire combos that we carry, like # AM3S550, do not come balanced like a passenger vehicle would be balanced at a tire shop. What manufacturers try to do is balance the heavy spot on the tire with the light spot on the wheel. Trailer tires do not have to be balanced beyond that unless you want them to be. Any local tire shop can balance them for you. I have included a link to an FAQ article on trailer tires for you.

  • Spare Tire and Wheel Recommendations for a Nitro Dual Axle Boat Trailer
    The 14 inch tire on your boat trailer is most likely a 5 on 4-1/2 bolt pattern. You will need a 14 inch wheel to match the other wheels on your trailer. I have included a link to an FAQ that shows how to measure for bolt pattern. The wheel that you referenced, # AM20504, is a 15 inch wheel and it has an offset which is not all that common. If you just want a wheel, # AM20352, is the most common. In the event that your wheels do have an offset, you would use # AM20304. For a standard...

  • Will an ST215/75-14 Trailer Tire Fit on a 6 Inch Wide Wheel
    If your trailer uses a 5 on 4-1/2 bolt pattern then you can use wheel # AM20352 which is 5-1/2 inches wide. Or for a tire and wheel combo with a Load range C 215/75D14 bias trailer tire use # AM3S550. A 215/75-14 tire will fit on a 6 inch wide rim. The rim width is not the issue since the tire width is over 8 inches so there will be no clearance issue.
