Features to know about

Ready for the Road Right Out of the Box: Pre-Mounted and Inflated Assembly

No extra shop time needed. The Kenda 4.80-12 Bias Trailer Tire comes already mounted on its 12" galvanized steel wheel and inflated to proper pressure—just bolt it on and go. At 18 lbs total weight, it’s easy to handle and install. The tire-and-wheel assembly meets Department of Transportation specifications, so it’s ready for real highway use the moment it arrives.

Built to Handle the Load: Load Range B with 785-lb Maximum at 60 psi

Strong enough for frequent hauls without adding unnecessary bulk. This bias tire has a 4-ply rating and carries up to 785 lbs at 60 psi, while the galvanized steel wheel itself is rated for 1,250 lbs. Together they give you dependable load support for everyday towing and longer trips alike.

Corrosion Resistance That Lasts: Galvanized Steel Wheel with 8-Spoke Design

Moisture, salt, and road grime don’t stand a chance against the galvanized finish on the 12" x 4" steel wheel. The coating resists rust and keeps the wheel looking solid season after season. Its simple 8-spoke design is tough and functional, built for years of exposure to wet or humid conditions.

Smooth Performance on Uneven Ground: Bias Ply Flex and Stability

This bias tire uses thick nylon cords laid at a 30- to 45-degree angle in alternating layers. That crisscross pattern gives the sidewalls extra stiffness so the whole tire flexes evenly over rough or uneven surfaces. It delivers a steady, predictable ride that feels stable behind you at up to its rated 65 mph speed limit (K-rated).

Reliable Specs That Inspire Confidence: Straightforward Fitment and Proven Durability

Key dimensions are dialed in for simple matching: a 4 on 4" bolt pattern, zero offset, 2.84" pilot diameter, and 1/2"-20 wheel bolts. The outer diameter measures 20.5" when inflated with a section width of 4.8". Backed by a 5-year tire warranty, a limited 2-year wheel warranty, and Kenda’s 1-Year Worry-Free Guarantee, it’s a setup made to keep rolling without fuss or guesswork.

Determining Bolt Pattern

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.

Center to Center
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).

Center to Outside Edge
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

by:

Wheels arrived quick look great and will look good on my kayak trailer I am working on. It was cheaper for me to buy these wheels and tires than to get just tires and have them mounted.



by:

Excellent product with super fast shipping -- etrailer.com never lets you down. The Kenda tires with Galvanized Wheels arrived "ready to mount." Quickly got my escapade trailer back on the road.



by:

Only took a few days to get . Mine came with load star tires , cheaper than just replacing tire , valve stems and installation . Nice galvanized finish . I got two wheels the price went up but it's still a good deal . This is my new TrAiler parts store



by:

Perfect wheel at a great price. Shipped fast.

This was an exact match spare for my new trailer. Great product.



by:

I purchased a pair of 4.80 x 12 trailer wheels and tires, and they are exactly what I hoped for to replace the 4.80 x 8's that were on the trailer. I do not currently have any miles on them yet, hence the 4 stars rather than 5.
Quick delivery, and the box and its contents survived shipping admirably.
The bolt-on 1-7/8" coupler is a cost-effective replacement for my old rusty one.



by:

Easy, my sales rep was super helpful and I received my tire is just a few days. I will definitely purchase from etrailer.com again!

So here's where the wheels and tires are headed , old wheels and tires are cracking like firecrackers .we try to navigate the lakes and ponds here in Wyoming



by:

Wanted a spare for my small boat trailer. Couldn't seem to find one in town and the dealer who sold me the trailer wasn't any help. I had no trouble finding an exact match to the tires and wheels on my trailer and the service at E-Trailer can't be beat.



by:

Company does not lack communication and shipping is reasonably fast.
I guess Kenda and loadstar is one in the same,my tires said Loadstar on the side.
i dont care about that and its a nice tire and wheel and looks like it will last a long time,fits my boat trailer and replaces worn and dry rotted tires and rusted wheels.
Wheels look better than the trailer.
So if you need tires wheels in general etrailer is the place to find and buy



by:

Wheel/tire package arrived two business days after ordering and were packaged in a very heavy duty cardboard container which was very impressive. This was the best packaging I've ever seen for such a large mail item - credit to etrailer for not skimping out on this, especially considering it was FREE shipping. Not much to say about the wheels and tires, they are as advertised, look nice, and will be a huge improvement over the 8 inchers that came with my trailer package. I definitely will use etrailer again in the future.



by:

Fit nicely , replaced 8” worn tires and wheels . Handled several 350 mile trips with loaded 4x8 trailer well, tires didn’t bulge with weight.



by:

Great product. Low price. Fast delivery.



by:

I was really impressed with the quality and appearance of the tires and wheels I purchased from E-trailer. Not to mention the speed with which they were delivered. I have them on my trailer already and they look great. The air pressure was perfect. I'm telling everyone I know where to buy tires and wheels. THANK YOU.



by:

Prompt, helpful service from staff in finding the right wheels and tires. Excellent experience and very cost effective too. This change in wheel and tire size works perfectly on our small utility trailer/wagon.



by:

Easy ordering, prompt delivery that arrived in good condition. Could not ask for more.



by:

I've had these for a year now, and I'm happy with them. I use the utility trailer about 10 times a year for various things like camping, hauling motorcycles, taking things to the dump etc. The trailer is outside all the time and the galvanized treatment is working great no signs of rust at all, they still look new. Tires are holding up well with little wear and the tubes inside must be good quality as the air pressure stay very constant. I would buy these again for sure.



by:

This wheel and tire package is perfect and matches the original wheels and tires on my boat trailer.I like the price and especially free shipping.I recommend this product it is a quality product.

yes



by:

We will see how well they hold up long term, but this tire and wheel combo was just barely more than the tires alone so I decided to replace the whole unit. My originals are starting to rust after 20 years so if I get close to that out of the wheels themselves I'll be happy. I hope the tires last 5 at least. A generic set of tires I bought last time didn't last 3 years in the sun.
Only negative is I wish the valve stems were slightly shorter. They stick out past the width of the wheel just barely and it seems they would be more vulnerable.

George, the tires dont show any signs of dry rot nor have went flat. The wheels dont show any rust yet. I wouldnt think either would have in just a year but thus far they are holding up great. As an aside, the local big box store] specials tires that were previously on that trailer dry rotted in 2 years and both failed on the same trip and really dinged up one of the wheels. It was usable, but rim dinged. Lets just say they wont ever see my trailers again. While I havent bought a lot from etrailer.com what I have bought seems to be priced about like some of the local budget brand stuff but seems like better quality stuff. Not premium, but good. I do wish etrailer.com carried more DIY small lawn cart type parts. I want to convert a small tire 2 wheel 15k generator to a larger/wider 4 wheel design with removable tow bar for lawn mower.

Thanks for the follow up, and as you noted at this time we do not have the components you need to build your small lawn cart. We are continuously adding new product and product lines to our offerings so please check back often and we may have just what you need.

great quality. reasonable price. quick shipping

Nice didn’t take long for delivery



by:

They seem to be working ok. Being on the boat trailer they don’t get much use. However, they are a great upgrade from the 8” tires. When looking for replacements e-tire knew exactly what I wanted. Great customer service quick order fulfillment.

  • Overall Diameter Of The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel AM30550
    Hi Robert! The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4 - Load Range B # AM30550 you were looking at has a diameter of 20.5" when fully inflated. This is a pretty typical diameter for a tire of this size, but a Radial option, like the # TA49QR, will be ever so slightly larger at 20.63" when fully inflated. You said you had plenty of room, but how far is the bottom of the fender/wheel well from the top of the tire currently?

  • 12 Inch Wheel & Tire For Trailer With Higher Speed Rating
    I cannot recommend going above the 65 mph limit of the load range B Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel - 4 on 4" Bolt Pattern # AM30550 or 5 on 4-1/2" Bolt Pattern # AM30590. Having said that, going to a higher-rated tire such as the Load Range C Taskmaster # TT53012C is also not a good idea for your trailer. The reason is they have about four times your load capacity so you would have to deflate them or your trailer would bounce to the point it could get dangerous,...

  • Can 8 Inch Trailer Tires be Replaced with 12 Inch Trailer Tires
    Hey, thanks. You're not so bad yourself! Going to a larger tire size is possible but there are a few things to think about. Chief among these things is clearance. When going from an 8 inch tire to a 12 inch tire the diameter will increase by 4.4 inches. This means that if there is anything above the tire such as a fender the larger tire may not fit. Even if you have the clearance now you also have to account for the travel of the suspension. The width between the two sizes is not a concern...

  • Is There a 4.80-12 Trailer Tire and Wheel With a 2-1/2" Hub Center Bore?
    The smallest wheel center pilot bore we have for a 4.80-12 trailer tire is going to be 2.84". Here is a list of the wheel and tire packages we have with that measurement. Do understand all these wheels are designed to be lug centric so they do not have to be the same size as the hub center.

  • Going With Larger Wheel and Tires on a Tear Drop Trailer
    I would first recommend that you check to see how much clearance your current tires have. This will help you determine if you can fit any larger tires without modifying the fenders or suspension. I like to have at least 1" of clearance throughout the suspension travel. I have included measurements for your tires below with a couple options to allow you to see what is available that may require little to no modification. 4.80/4.00-8 # AM30040 -Width- 4.7" -Height- 16.1" 5.70-8 # AM10010 -Width-...
