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"

  • What PSI Should Be Used On Golf Cart Wheel That Say 30 PSI On The Sidewall
    The air pressure in any tire should be listed on the tire itself and if it says 30 psi, that is the psi I recommend using. Special trailer tires should be inflated to their maximum air pressure. for example, the tire you came from, part # AM40537 has the psi listed at 22 on the sidewall. If a trailer tire is inflated to a lower air pressure than the maximum, the amount of weight that the tire can carry will be reduced. If a heavier load is put on the trailer tire than what is recommended...
    view full answer...
  • Recommended Tire Pressure for a Golf Cart Tire
    For golf cart tires you want to go with the middle of the air pressure range that is designed for the tire. Most likely the range for your tire is 18-22 psi so 20 psi would be ideal. Too much pressure and the ride quality will be harsh and the center of the tread will wear out. Too little pressure will cause the sidewalls to wear out.

  • Recommended Replacement for Kenda 215/60-8 Trailer Tires with More Narrow Section Width
    There is not a spacer or an offset wheel for your application, however you can use the same wheel and put the Kenda K389 Hole-N-1 Bias Golf Cart Tire - 18x8.50-8 - Load Range B # AM40537 on it and gain 0.4 inches in space due to its 8.5 section width.

  • Availability of 18x8.50 Size Tire
    We do have one tire available in the 18x8.50-8 tire size you mentioned with the Kenda K389 # AM40537. This bias ply tire features a maximum load of 815 pounds at 22 psi and is designed to fit 8 inch x 7 inch wheels. The tire comes with a limited 2-year warranty. I have attached a short video demonstration on this tire that you can also check out.

  • Recommended PSI for 18 x 8.50-8 Size Trailer Tire
    Check the sidewall of the tires it should list the maximum psi. Most trailer tires should be inflated to their maximum psi when they're cold in order to get the best performance and wear out of them. Some manufacturers use a different psi for different applications but this isn't very common, especially on an 8 inch tire. For example, the 18x8.50-8 tire we carry, part # AM40537, maxes out at 22 psi as shown on the sidewall. Other tire manufacturers won't necessarily be the same but...

  • Can you Replace Just One Tire on an EZ Go Golf Cart
    You can most certainly replace just one tire on your golf cart. One thing to keep in mind is to make sure the one you use matches the specs of the others. The Kenda K389 Hole-N-1 Bias Golf Cart Tire, part # AM40537, is a bias tire that fits 8" x 7" wheels with a load range of B. It has an outer diameter of 17.6" when inflated. I've linked to a video review of this tire below.

  • Recommended Golf Cart Tire That is Size 18 x 8-1/2 Inch
    I recommend the Kenda bias golf car tire and wheel # AM90002 because it will have a 815 pound maximum load at 22 psi. It's also a 4 on 4-inch bolt pattern. If you need the tire only, go with the Kenda bias tire # AM40537. This tire is specifically made for golf carts and the bias ply construction is quite strong and rugged. I included a helpful article and video review on the tire # AM40537 for you as well.

  • Best Replacement 18x8.5-8 Trailer Tire for Snowmobile Trailer
    The best option we have for you is the Kenda K389 Hole-N-1 Bias Golf Cart Tire part # AM40537 or the Kenda 18x8.50-8 Bias Golf Cart Tire with 8" White Wheel part # AM90002 which both come with a two year warranty and 65 mph speed rating.

  • What is the Difference Between a 18x8.5-8 and 18x8.5-10 Tire?
    The difference between your 18x8.5-8 tire and the 18x8.5-10 is the size of the wheel; the 18x8.5-10 is going to have a 10" diameter wheel, which unless you had the available clearance and wanted to change all 4 wheel/tires is going to be too large. You'll want to replace your existing tire with the same size tire like the Kenda # AM40537 , which is a Load Range B tire that is size 18x8.5-8 and will match your current tires. If you wanted to replace the entire wheel, you can use the # AM90002...

  • Availability of 18/8.5-8 Size Tire Without Wheel/Rim
    I believe you meant the tire size 18/8.50-8 which we have as the Kenda K389 Hole-N-1 Bias Golf Cart Tire # AM40537 that doesn't have a wheel. Currently we do not have a tire with the size 18.5/8.50-8. This tire has a load range B (815 lbs at 22 psi) with a section width of 8.5" and an overall outer diameter of 17.6" when inflated to 22 psi.

  • Wheel and Tire Compatibility with Toro Z4200 Riding Mower Rear Tires
    The 18x8.5 will give you a tire wider than your 7.50 tire. It will give you more tread because of the width so you will have better traction as well as a slightly wider mower as the tires will add 3/4 inch to the outside of each tire. You will want to make sure you have the internal clearance for the extra width of tire without making contact with the wheel well or frame. The Kenda K389 Hole-N-1 Bias Golf Cart Tire - 18x8.50-8 # AM40537 is a great option for your riding lawn mower wheels....

This particular assembly will provide you with a maximum load of 815 pounds at 22 psi and does have the needed 4 on 4" bolt pattern.

    I have another option for you, but the Kenda K500 SuperTurf Tire with 8" White Wheel - 5 on 4-1/2 - Load Range B # AM89992 is for off-road use only and cannot be used on the highway. Instead I recommend the Kenda K389 Hole-N-1 Bias Golf Cart Tire - 18x8.50-8 - Load Range B # AM40537 which will be an exact replacement for the 18.x8.5-8 tire on your 1999 Comfab Trailer, and has a load rating of 815lbs at 22 PSI.

  • Substituting 215/60-8 Trailer Tires for 18x8.5x8 Tires on Golf Cart
    Since a golf cart typically weighs quite a bit less than a loaded trailer, going with a 215/60-8 tire like part # AM1HP26 will give you a total weight capacity of 3740 lbs. Overkill? Probably. It also means that you'll get longer life out of the tires. The slightly more aggressive tread of the # AM1HP26 will also contribute to longer tire life. If you're needing the wheel/tire combo, we offer the wheels in a 4 on 4 or 5 on 4-1/2 wheel bolt pattern. If you're unsure of your current wheel...
