No extra shop trip needed. The Kenda 4.80-12 Bias Trailer Tire with 12" White Wheel (part #AM30580) arrives mounted and properly inflated, so it’s ready to bolt on and go. The assembly meets Department of Transportation specifications and combines a strong steel wheel rated for 1,250 lbs with a bias tire carrying 785 lbs at 60 psi. It’s a simple, reliable swap that gets your trailer rolling fast.
When you’re pulling weight day after day, dependable load support matters. This tire’s Load Range B, 4-ply build is rated for a maximum of 785 lbs at 60 psi, giving you confidence under typical hauling conditions. Its bias-ply design uses crisscrossed nylon cords set at a 30-45° angle for firm sidewalls and steady handling when towing on uneven or rough pavement.
Corrosion doesn’t stand a chance here. The 12" x 4" steel wheel from Dexstar gets both an e-coat primer and a white powder coat finish that help seal out moisture and grime. That double coating keeps the wheel looking clean while resisting rust through rain, road spray, and long-term outdoor storage.
Choosing the right setup is straightforward with this combo’s common fit specs. The wheel features a 5 on 4-1/2" bolt pattern, 0 offset, and a 3.19" pilot diameter. Wheel bolts are sized at 1/2"-20, giving you the solid lug-centric fitment most trailers use for safe, centered mounting.
For the first year, any tire damage is covered—Kenda replaces it at no charge under its worry-free guarantee. That’s backed by a 5-year tire warranty and a limited 1-year wheel warranty, so you can haul knowing you’re protected mile after mile.
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"

Ratings & Reviews
Discount Tire failed me three times for these wheels, and they threw my old ones away. Thanks
Tires and rims look good and were offered at a great price. Time will tell if the Kenda tires holdup to normal road use.
Thanks Etrailer I received the trailer tires on time and ready to install
The tires really look good I was able to try them out last Sunday and the ride was smooth I definitely order again from you guys.
The product is exactly what I needed, I recently bought an old boat trailer and the wheels were dry rotted, so I needed them replaced. Etrailer really made it easy to find and purchase a new wheel. definitely going to look to them for my next trailer accessories purchase.
Nice wheels and tires at good price, delivered promptly and in good shape. I look forward to mounting them and driving off down the road.
Etrailer has excellent products well priced. Tires and wheels already mounted and shipped out in no time made replacement simple.
Easy site to find my tire, and wheel size. Great prices, Fast shipping. They look good on my trailer thanks for the great deal.
Paula was very helpful. Knowledgeable and courteous. Product came quickly and packaged securely. Haven’t used the trailer spare tire yet but at least got the correct size delivered. Not so trusting of tow strap. We shall see. Thank you
The wheel/tires arrived in great condition and is exactly as ordered. It took awhile before I received them due to oem supplier delays, but etrailer did a great job in keeping me informed and offering ready-to-ship alternatives if time was critical for me (it wasn’t).
Tire and rim was just the product for my utility trailer. Accompanied by the spare tire bracket, it fits perfectly. Delivery was very prompt. This was the second purchase from etrailer that I made. Previously I purchased the trailer hitch that I mounted on my car. Great company to do business with!
Excellent tires/wheels for the quality and price!
I shopped around and was quite impressed when I came across this on-line retailer. The web site's ease of selecting, narrowing down the options, and ordering made me confident that I was getting the right size wheel and type of tire for my husband's boat trailer.
Etrailer.com's customer service was EXCELLENT. I placed the order on a Thrusday night and in LESS THAN two hours, had shipping/tracking information and three emails to let me know the status.
The ease of ordering, excellent communications, and speedy delivery will make this my go-to site for all of our future trailer needs.
Highly recommend!
Reasonable price, free shipping and timely arrival.
Ordered spare trailer wheel and tire and hubcaps. Hard to find the exact items on web, but etrailer had everything. Received correct order promptly.
I don't often write reviews but I am so impressed with etrailer's website and the tires I received that I'm making an exception this time. First, the amount of information on the website was superb, all the spec's , videos, etc were excellent and helped me be sure I was going to get what I wanted. The price was good so I ordered. The tires arrived in under a week and are exactly as described. More importantly, they were "fresh" meaning that they had not been sitting on a rack somewhere for a long time. Tires, like milk, need to be fresh when bought as trailer tires usually die of old age rather that wearing out the tread. Anyway, the tires arrived in great shape (good packaging) and I am delighted with my purchase. I'll be buying more from this excellent company.
Installed these brakes on my 5th Wheel in the summer of 2023. Completed the installation in two easy days with 2 other old men. Takes a little creativity placing hydraulic lines and the pump. Love this conversion. Never go back to drum brakes. Had to go from 10 gain on the drum brakes to 3 gain on the disk brakes. Driving through heavy traffic is so much less stressful knowing I have 10 wheels with disk brakes (6 on the RV and 4 on the truck). Stopping distance is reduced enormously. No problems with any component in the packaged as of 07/2024.
Excellent service and contact. Delivery prompt and product was perfect. I would use this "etrailer" source again. The source provided clear and thorough product information and guidance for accurate ordering. Unusually precise and accomodating source.

just fine. no problems whatsoever
works great!
Fast delivery and everything is as described. Very happy
Great tires and price. I just mounted them on the trailer this week and ghey look great. Planning to pull my bass boat to Canada this summer!
Competitive pricing, quick ship....good stuff!
Super fast delivery and just what i needed. High quality tires and wheels from etrailer.
Had a Chinese trailer I bought in a box from Home Depot -- they were of no use getting registered or most importantly, getting info on wheel and tire size. I copied the cryptic writings from the wheel, went online to eTrailer and Voila! The right size in English so it was easy to order and arrived quickly! Now I have a spare wheel and tire. Thanks eTrailer!

Glad we could help translate the cryptic writings on your wheel! What kind of gear/equipment are you going to be hauling on the trailer?
I have yet to install on my trailer, but ordering, delivery and communication throughout process has been excellent.

Trailer tires are still fine. I went to the dump today with a load of pruning. Glad to be rid of my old cracked, leaking tires.
