This Kenda Loadstar K399 tire is made for work. It’s a bias-ply design built with thick nylon cords set at a 30- to 45-degree angle, giving it strong, stiff sidewalls that hold up under load and flex together on rough ground. Rated Load Range C with a 6-ply rating, it carries up to 935 lbs at 50 psi. The bias build gives it superior stability when towing across uneven surfaces or soft ground.
When a job takes you out on the road, this tire is ready. It’s speed rated M for 81 mph and exceeds DOT standards, so it handles highway speeds without worry. The tough construction resists heat buildup and rolling resistance stays low for a smooth, confident ride mile after mile.
This tire fits standard 8" x 7" rims with an inflated outer diameter of 18.3" and a section width of 8.9". That makes it an ideal match for setups using modern 18.5x8.5-8 equivalents while keeping clearances consistent. The proportions give solid ground contact for traction and control when loaded or empty.
Durability is backed by coverage that matters. The Loadstar K399 Bias Trailer Tire comes with a 5-year limited warranty plus a 1-year worry-free guarantee—if it’s damaged in the first year, it’s replaced at no charge. That kind of support means you can get rolling knowing you’re covered if something goes wrong early on.
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"

Great customer service! Great schedule updates, delivered a day earlier than estimate, great quality product at affordable price!!

Great tires, fast shipping, and great s ervice.
Fast shipping. Got my tires just in time for my weekend plans.
We use these on utility carts and 4 wheel nursery trailers at a tree and shrub nursery. They work great

PERFECT TIRES FOR MY APPLICATION AND FAST DELIVERY. ALSO CUSTOMER SERVICE IS GREAT, WE HAD AN INCIDENT WITH FIRST ORDER, BECAUSE BOX CAM OPEN AND UPS LOST 1 OF THE 2 TIRES. I INFORMED THEM AND THEY SENT OUT THE OTHER TIRE SAME DAY.
I needed to bring an old trailer back to life. These tires were the perfect replacement to the dry-rotted tires on my ATV trailer.
These are the best tires I can find for the golf carts used by our security staff. They are driven on asphalt a lot and regular golf cart turf tires wear out very quickly. These DOT trailer tires fit great and last a lot longer.
Tires matched my old ones which were on my golf cart. Arrived in a timely manner and no damage to the package. They give a great ride on the golf cart. I will definitely purchase from this same distributor the next time a need more tires. I also called the distributor and they were very helpful in answering any questions.
Bought two tires and rims for my snowmobile trailer. Great tires and great price. Fast delivery,
Many thanks to Natalie for the help she was in making my purchase of 3 Kenda tires & 1 galvanized wheel painless!! She helped me navigate your website to find the correct size & load range for my application. And she sent follow up emails with order & tracking info as well. My order arrived a day earlier than expected, thank you etrailer
Great service very helpful over the phone and they made sure I was getting the right tires for my use and the right size rims for my trailer. My experience after installing new tires and rims on my snowmobile trailer I no longer had the vibration I was feeling while towing so the new tires made a tremendous difference in how it towed the trailer. Thanks again for your assistance
Haven't road tested yet but received correct tires in good shape and met the delivery date I expected.
We bought a set of these mounted on wheels for a manlift. Excellent tires with a great load rating. Sliced one running over metal. Called and talked to Teresa who was great. She got a tire on the way. Once again etrailer was great. Probably start using these tires on our golf carts too. Thanks again Teresa!

Excellent tires. Not one problem.!I will buy more for the golf cart
Ordered two Loadstar K399 215/60-8 load range C for my snowmobile trailer. My old tires were 5 years old and starting to cup bad so I thought I’d put a no set of tires on before winter. I received free shipping and tires arrive within a reasonable time. Local tire shop put tires on my galvanized rims that I also purchased from E-trailer. Very happy with the quality of service I receive from E-trailer! From start to finish!! Gold Star

Tires are still holding air. I’m still very happy with my purchase.
The golf cart tires are exactly what I wanted. I replaced with exactly the same tire which I had on the cart for 16 years. The service and ordering process was very prompt. Thanks for a great product.
Great trailer tire for the price!
The tires come VERY compressed and even after a few days in the sun, they didn’t relax so I used 2 ratchet straps to get the tires to take shape enough to get beads to set.
Great service and delivery

the tires are good so far, i have 4 of them on a little dump trailer i designed and have carried 3000 lbs of 3/4" stone (just over a yard), so i'm happy.
the tires i started out with were just golf cart tires and were iffy with this kind of a load and these are rated more for the kind of weight i can carry and dump. here are some pics... i have a video of it dumping 3000 lbs at

Product is still in great shape after one year of use. Was able to pull my sleds everywhere last year.
