This Kenda Loadstar K371 Bias Trailer Tire is built and tested to exceed Department of Transportation standards, so it’s ready for consistent duty. With a Load Range B rating and a maximum load of 590 lbs at 60 psi, it delivers reliable strength for smaller trailers that still see real miles. The 4-ply construction keeps the casing tough without adding unnecessary weight or stiffness.
The bias design uses thick nylon cords positioned at a 30- to 45-degree angle, alternating in a crisscross pattern. That makes the sidewalls more rigid while letting the whole tire flex together over bumps and ruts. The result is a stable, controlled ride that holds steady when you’re rolling across driveways, gravel, or rough terrain.
Even though it’s small in diameter at 16.1", this tire holds its own on the open road. Every 4.80/4.00-8 Kenda bias tire in this series carries a 65-mph speed rating, so you can run highway speeds without worry about heat buildup or early wear when properly inflated to max pressure.
Kenda backs this tire with a 5-year limited warranty plus a 1-year worry-free guarantee that covers replacement if it’s damaged in the first year. That kind of backing adds peace of mind when you’re depending on your gear to keep rolling season after season.
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"

just what I ordered
These tires are perfect in every way. What I received was exactly what I was expecting. I would absolutely recommend etrailer for tire needs.
Replacing old leaking tires for a 14 Aluminum John Boat trailer. Mounted fairly easy the old fashioned way. Still holding 45 psi 24 hours later.
Much better than the wheel barrow tires I was using. 4 ply instead of 2 ply. Worked great on the old Gravely Pro Master mower. Hopefully less flat tires.
The tires per se were ok. The problem was that they were crushed pretty much flat, probably while in storage, and they were very difficult to get mounted on the wheels. Once mounted and with new tubes installed, I have had no further issues.
etrailer always comes thru! Competitive pricing, order updates from placing to delivery and reliable UPS shipping. The tires were put on my oldie but, goodie wood splitter.
Came crushed flat. Had quite a struggle to get it open enough to put it on the rim. When I did finally get it on the rim I wasn’t able to get the beads to spread out to the rim so I could pt air in it. I had to take it to a local tire shop who had a large tank of air used for inflating large truck tires. I’ll never get a tire here again. Next time I’ll go to Tractor Supply or someone else that has tires not deformed.
Great tire! A little tough for me to wrestle onto the rim, but my buddy Charlie did it easily with tire spoons. It is tubeless, it sealed really well, it's DOT approved for highway use, and it is a perfect fit for my heavy duty 7/8 axle utility trailer. For my off road use it will live forever! Thank you.
I had trouble getting this tire locally but you guys had it at an excellent price.Your shipping was extremely fast and reasonable.

still working good as new
I have an old wheelbarrow that takes this size tire. This trailer tire is much higher quality and carries much more weight than an ordinary wheelbarrow tire. Installation was simple using the old tube. I am very happy with this product and the service.
The tire arrived quickly and was reasonably priced. However,I noticed that it was quite distorted. It mounted on the rim easily enough but getting the bead to seat was a nightmare. Several sessions in the sun and lots of cursing with the ratchet strap I managed to get the distorted and squished part to seal enough to seat the bead. I've purchased many tires and mounted them before but I never had one in such s twisted, flattened shape. Otherwise the tire seems fine.
etrailer shipping and price were GREAT!
The issue I have is with the tire itself. The date code is nearly 2 years old and they arrive looking like it. Smashed into a pancake that took a lot of time with my straps, tire changer and warming up in the sun to mount and seat. Fortunately I have a motorcycle tire changer and am experienced with tires to get them mounted and seated.
No wonder all the local places only sell the tire mounted on the wheel!
My wheelbarrow got a flat...again. So I tried a different route. It's a trailer tire but I noticed it is 8in, the same as my wheelbarrow. This is a much more robust tire than the ribbed [tire] that typically lives there. I think the load rating is like 750lbs, way more than I will ever put in there. Anyway if you want to put a truly heavy duty tire on you wheelbarrow, this is it. etrailer had the best price and it got here fast.
Its not so much your product its your storage methods. You pride your shelves as being for the DIYers your tires are distorted from improperly storing them.
Exactly what I ordered. Customer rep Lauren was fantastic and found just what I needed. Great price and and fast processing the order
Shipping was quick, product was as described. Quality product
Kenda tires are shipped by the thousands from Asia, compacted flat on their sides, and arrive looking like skinny frisbees and are nearly impossible to mount. I knew I was buying cheap for a cheap project but you should know these tires are horrible.
I like you guys and will buy from you again, but never Kenda tires!

It's common for bias ply trailer tires to be shipped in that manner. A good, high volume tire shop should have no problem getting them mounted.
The tire received had a problem for me. One of the beads was badly warped but I thought with my simple tire mounting equipment I'd have no problem. I was wrong!
No amount of effort would mount the second bead. Even borrowed a Blaster and after several attempts I could not get it to mount. Took it to a tire shop and after much effort, blowing shop air thru the stem on one side while using a blaster on the other finally mounted the tire after several attempts.
Perfect match for an old 1960's era Montgomery-Ward utility trailer I found buried in a junk pile and restored for use on the farm behind ATV and golf cart.

Working great! Tires holding-up just fine and we use that cart daily for hauling material on the farm.
The tires look great and I’m just waiting for warmer weather to put them on my wood splitter.

Tires are great!
The tire wasn't damaged but it had been deformed by having stuff stacked on it making it difficult to put on the wheel.
That said, the service was great and the price was fair
I could have saved a few dollars purchasing elsewhere, however, my trust is in etrailer to supply products I can rely on when everything is riding on them. I have not yet installed the tires I have purchased and being the same brand, size, and load range as the ones they are replacing, I have no worries their performance will equal that of the tires they replace. And while fit is important regarding replacement tires, so is their speed rating. Not all tires share the same speed ratings and again, I can be assured these tires meet all legal highway and freeway speed limits in the US.
Great trailer tires, used them for over 10 yrs, never had any issue !
These arrived flattened as others have said. However, I just put the tubes in them for a few hours and they mounted easily. I mounted these without the tubes and used a ratchet strap to help seat them on the rims. I took just over ten minutes for the pair to get mounted. These look great and are very sturdy. I have Kenda tires on my other equipment and have been very happy with the brand. etrailer always meets my expectations with fast delivery and a good price.

They sat all winter in the shop building and were still holding the correct pressure this spring. The tires that came on this trailer had to be aired up every time I used them.
