The Kenda K500 SuperTurf uses a bias-ply construction with thick nylon cords set at alternating angles to boost stability and handling on uneven surfaces. Its 18x8.50-8 tire size offers a wide footprint and smooth, controlled traction. With a ply rating of 4 and an 815-lb maximum load at 22 psi, it’s ready for steady performance in off-road conditions.
The included steel wheel is built for long-term durability with a solid-center design and 0 offset for balanced weight support. Measuring 8" in diameter by 7" wide, the wheel is rated for up to 1,040 lbs and uses a 5 on 4-1/2" bolt pattern with 1/2"-20 wheel bolts and a 2.81" pilot diameter for straightforward setup.
The white powder coat finish is applied over an e-coat primer to help lock out moisture and prevent rust. Even after full exposure to the elements, the finish stays bright and clean while maintaining its structural protection.
Rated K for speeds up to 65 mph, this combo maintains reliable performance under typical trailering and off-road conditions. The bias design minimizes rolling resistance, offering excellent handling and a smooth ride when loaded or empty.
Each assembly meets Department of Transportation specifications, ensuring dependable quality from the tire tread to the steel rim. It’s a tough, well-matched setup that’s built to handle workdays or weekend runs with equal confidence.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

So far a year in and no issues! Only thing I’ve noticed is that yes they gave extra height for my golf cart but the tires are a little wider and rubbing against some of the inner wall. However, that’s no fault to the tire, shocks need to be replaced causing this issue. Otherwise would highly recommend to anyone!

It's good to know that this will also fit on a ram rod! I know for sure this will help someone else down the road. Thanks, David!

I checked and with this tire size and bolt pattern this is the only size tire that we have. I will definitely have our customer service team reach out.

Still working excellent. Etrailer is a gem. Honestly I wasn’t sure if the price reflected the quality but a year later the tire hasn’t gone flat and held up to a good beating. Highly recommend !
