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"

Let me break this down like this. First the tire wheel assembly I ordered is spot on. Its a spare so it does what a spare does it just sits there ready if needed. Second....Do you have some magic up your sleeve? I lost a bet on the delivery. My order arrived so fast you must own UPS. Thanks for the product and outstanding delivery time. 409445

Ask the Experts about this Kenda Trailer Tires and Wheels

  • Does Kenda Karrier Radial Tire and Wheel # AM31990 Come Balanced
    The Kenda Karrier ST175/80R13 Radial Tire and Wheel # AM31990 that you referenced does not come balanced but it also doesn't need to be. Trailer tires are built and ride much differently on the road than standard passenger tires. Because of the rougher ride on a trailer (especially when it's empty) weights can be thrown off from the excessive bouncing and movement. You certainly could still take the tires up to a local shop to have them balanced if desired but it's simply not necessary....

  • Upgrading EZ Loader Boat Trailer Tires and Wheels to Radial Tires and Mod Wheel Size ST175/80R13
    The Kenda Karrier ST175/80R13 Radial Trailer Tire with 13" Black Mod Wheel - 5 on 4-1/2 - LR D # AM31990 will work just fine for your EZ Loader boat trailer. Moving to radial tires over the bias tires you currently have will only help for better traction and reduced wear as you travel on paved roads. The load range C tires that came on your trailer originally were simply a slightly softer sidewall than your current load range D tires. They have a stiffer sidewall and higher ply rating. The...

  • Backspacing of Kenda Karrier ST175/80R13 Radial Trailer Tire with 13" Black Mod Wheel # AM31990
    The Kenda Karrier ST175/80R13 Radial Trailer Tire with 13" Black Mod Wheel # AM31990 has a zero offset which means the backspacing is exactly the width of the rim plus an inch to account for the mounting lip. So that means the backspacing is 2-3/4 inches.

  • What Tire Pressure Should Kenda ST175/80R13 Radial Trailer Tire with Wheel LR D Inflate To
    Trailer tires need to be inflated to their max psi rating when cold to ensure you get the full weight capacity and prevent heat build up. For the part # AM31990 that you referenced that pressure rating would be 70 psi.

  • Can 12 inch Trailer Tire Be Upgraded to 13 inch Trailer Wheel and Tire
    An ST145/R12 tire like the Kenda Karrier S-Trail # AM10140 measures 21.3 inches in diameter when inflated and is 5.7 wide. The smallest 13 inch tire is ST175/80R13 quite a bit bigger, measuring 24.1 inches in diameter and 7 inches wide. You'll need to measure to determine if you have clearance. If so, and if you have a 5 on 4-1/2 inch bolt pattern there are a number of options available for this tire with different styles of wheel (if you are unsure of your exact bolt pattern you can...

  • Looking for Smaller Diameter Replacement Tire for Bass Boat Trailer
    By looking at the photo you provided, I can see that you do indeed have a clearance problem with the fender. Going to a 13 inch wheel/tire combo like the Kenda Wheel/Tire Combo part # AM31990 for a black mod wheel or # AM31991 for a white mod wheel would improve your clearance issue to a degree. Both wheels have a 5 on 4-1/2 wheel bolt pattern, and both feature a ST175/80-13 Load Range D tire that has a 1650 lb weight rating per tire/ 3300 lbs per axle when properly inflated to the maximum...
