Features to know about

Made for Steady Hauling at 65 mph: Load Range B with 590-lb Tire Capacity

This Kenda 4.80/4.00-8 bias trailer tire and wheel combo is built for small-scale towing that still demands reliability at highway speeds. Rated for 65 mph, the tire carries up to 590 lbs at 60 psi with a 4-ply rating, while the matching steel wheel handles 910 lbs. Both meet Department of Transportation specs, so you can roll with confidence trip after trip.

Built to Resist Rust and Corrosion: White Powder-Coated Steel Wheel

The steel wheel features a corrosion-resistant finish designed to stand up to wet roads and storage weathering. A white powder coat over an e-coat primer seals out moisture and grime, keeping the wheel looking sharp season after season without flaking or peeling.

Smooth Ride Over Rough Surfaces: Bias Ply Construction for Balanced Handling

This bias tire uses thick nylon cords set at a 30- to 45-degree angle, alternating in a crisscross pattern that stiffens the sidewalls while letting the whole tire flex evenly. That design helps absorb ruts and uneven terrain, giving you steadier handling and a smoother ride when trailering on back roads or job sites.

Straightforward Fitment Every Time: 5 on 4-1/2" Bolt Pattern with 0 Offset

The 8" x 3-3/4" steel wheel uses a common 5 on 4-1/2" bolt pattern, a 2.8" pilot diameter, and zero offset for simple alignment with standard hubs. Wheel bolt size is 1/2"-20. When inflated, the tire measures 16.1" in outer diameter and 4.6" in section width—compact, consistent dimensions that make fitment predictable and hassle-free.

Extra Peace of Mind on Every Tow: One-Year Worry-Free Guarantee

Kenda backs this setup with a one-year worry-free guarantee—if the tire is damaged within the first twelve months, it’s replaced at no charge. It’s backed further by a five-year tire warranty and a limited one-year wheel warranty for lasting assurance on every haul.

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"

I've had these on for about a year. They were the cheapest I could find and I've had no issues with them. The trailer doesn't get used very often, the tires probably only have about 1,000 miles. One long road trip at high speeds in pretty warm weather, and the rest local trips in varying weather. No cracks, leaks, or other signs of trouble with the tires and the wheels held their torque where some tend to loosen after the initial installation.



by:

Excellent match to the old tire and wheel I'm replacing. Couldn't find this tire on a 5-lug wheel in local shops, etrailer had what I needed.

Have now had the new tire and wheel on my trailer for a year. I dont haul things a great deal but it has had its share of heavy loads of mulch and a few 40-100 mile highway trips and is doing great.



by:

Haven't used the spare I purchased yet, which is good, but the folks at etrailer offered this at the best price I could find and shipped it very quickly. They are in my favorites folder now and will probably will get the next order for more trailer goodies. I have four trailers of various kinds so there is always a need.

Exactly what ui needed. Powder coat looks good, came fully inflated too.
I really like that etrailer has an informative video with the guy showcasing the product having him in the video was really helpful to get a sense of scale, and I learned that you measure from inside the rim which helped me get the right dimensions to make sure I was ordering The right size

Tires and Wheels seem of good quality and solid. They went on without a problem and look great. Didn't have time for a road test but felt solid on a quick trip up and down the street.



by:

I bought a use jet-ski trailer, after a couple of weeks the tires went flat, noticed they were weather worn. Bought these tires to replace the bad ones. Worked great, looks great. Exactly what I needed at a very reasonable price. Super fast shipping.



by:

It fits and looks good. Reasonable price and quick shipping. I haven't had it out on the road yet - just got it mounted on the new hub. Thanks for your help.



by:

Time in a timely fashion and look good. The issue is that one wheel has the divots to hold the hub cap and the other doesn't. Emailed Lauren a week ago for follow-up and have heard nothing.



by:

I have a small boat trailer that these tires are just right for. The trailer sat out for a long time and the original wheels were going to cost to much to fix. This was the easy option. They work great.

Looks good John, glad to know we've been able to provide that top notch experience. We appreciate you choosing etrailer!



by:

The tires arrived quickly. The DOT date codes on the tires were recent. The wheels were well painted. What can I say? They're wheels and tires.
I'd give them a 5 if I had driven them more than just a dozen miles.



by:

Bought to replace dry rotted tires. Shipping was as promised and packed well. Tires came inflated exactly to spec. Rims fit and small boat trailer rides noticeably smoother. Would purchase again.

  • What is the Difference Between 4.80/4.00-8 and 5.70-8 Trailer Tires for a Boat Trailer
    Both the 4.80/4.00-8 and 5.70-8 tires sizes will fit the same wheel size, 8 x 3-3/4 inch. The 5.70 is taller by 2 inches and wider by 1.2 inches. If you have more than 1 inch of space between the tire and a fender and more than 1.2 inches between the side of the tire and the trailer then you can use the larger size such as # AM10010 rated for 715 pounds at 50 psi. If you do not have the space then stick with the same size you have, 4.80/4.00-8 using # AM10002 rated for 590 pounds at 60...

    Hey Mike, for your trailer I recommend checking out the Kenda 4.80/4.00-8 Bias Trailer Tire with 8" White Wheel # AM30020. These are 4.80/4.00-8 tires with a 5 on 4 1/2 lug pattern, has a B load range, a weight capacity of 590 lbs. at 60 PSI, and will work great for your upcoming road trip.

  • Can Adding Larger Tires to a Trailer Increase Its Capacity
    I am glad you asked these questions. First, to tow a trailer level you need only a ball mount with the proper rise or drop. I have included a link to our FAQ article that explains how to measure for rise/drop and a link to our ball mount main page. For the tires, going to a higher capacity tire does not increase the capacity of the trailer itself. The trailer capacity is set by the axle capacity. There should be a plate or sticker on the trailer tongue or frame somewhere that lists the...

  • Solution For Needing Higher Speed Rated Trailer Tire Size 5.30-12
    We have trailer tires in the size of 5.30-12 that have a higher speed rating like the part # TT53012C but we do not have them mounted on a wheel. This tire is rated for 81 mph. So you could go with the tire and have them mounted on your current wheels or go with new wheels too and have them mounted locally like with # AM20153.

  • What Air Pressure Should I Run in My Trailer Tires?
    We recommend that all trailer tires be inflated to the max psi stated on the sidewall of the tire. If the tire is under inflated, the weight capacity is lowered to an unknown amount for that tire. Although running lower air pressures can improve the ride of the trailer with lighter loads, the weight rating that the tire can carry will be reduced. If a heavier load is put on the trailer without changing the air pressure to the recommended amount, the sidewall of the tire could heat up and...

  • Recommended Tire Pressure for a Pace Ralle Dual-Axle Enclosed Car Trailer
    I appreciate your confidence but I am going to need a bit more information to answer your question accurately. What kind of tire do you have? What size is it? Whatever those tires say as far as PSI goes is what you will want to do. There is only one brand of tire, Goodyear, that has approved PSI levels as far as weight goes. Every other tire has a recommended PSI, which you will want to follow. It looks like your trailer tops out at 10,000 lbs capacity depending on the model year. Do...

  • Should Trailer Axle be Changed from a Normal Axle to a Torsion Axle on Home Made Tear Drop Trailer
    You can go to a torsion axle and different tires and wheels if you so choose. You have to consider what you are trying to accomplish by doing so to determine if it is worth the expense or not. Normally I would say you could change to a different tire size if there is clearance to do so but Harbor Freight trailers tend to have odd bearings and if changing the hubs is required to go to a larger size tire and wheel you may not be able to without changing the axle any way. If you do change...

  • What PSI Should I Fill My Trailer Tires To?
    Hi Leo! This is a question that comes up every now and again and there are a lot of differing opinions out there in the ether. What we always stick with is what we have been told by all the tire manufacturers, as they will know best. If your tire is rated to 80 psi, that is what you will want it filled to (when cold). The only exception to this rule is Goodyear. They have a chart that lays out what the capacity will be at a specific psi, but again, they are the only ones that do this....

If you move to the larger tire # AM30140 you will have a tire width of 5.9 inches and an outer diameter of 18 inches. This gives you a little over 1 inch more tread on each tire and also gives you almost 1 inch more ground clearance. It will increase your load capacity to 910 lbs at 75 psi. These tires will wear a little better...

  • Switching From 4.80-8 to 4.80-12 Trailer Wheels and Tires With a 5 on 4-1/2 Bolt Pattern
    First, I do recommend verifying exactly how much clearance you have. The Kenda 4.80-12 Bias Trailer Tire with 12" Galvanized Wheel # AM30670 you are looking at is 20.7" tall while your Kenda 4.80/4.00-8 Bias Trailer Tire with 8" White Wheel # AM30020 is 16.1" tall. The 4.6" difference will be 2.3" loss of fender clearance. It is recommended to have 3" of vertical clearance for suspension travel with the taller tires.

    The special trailer (ST) tires will have a maximum speed rating of 65 miles per hour, unless stated otherwise on the tire. It is not recommended to run a trailer tire at a higher speed than 65 miles per hour due to the heat buildup that will occur inside the tire and cause the tire to break down and cause the tire to fail. The smallest 5 on 4-1/2 bolt pattern tire and wheel we sell is Kenda 4.80/4.00-8 Tire with 8 Inch Wheel, part # AM30020. It has an overall diameter of 16.1 inches. The...

    The Kenda K353 Bias Trailer Tire - 5.30-12 - Load Range C # AM10066 has a speed rating of 65 mph and like you mentioned a max load capacity of 1,045 lbs at 80 psi. However you should make sure that the combined maximum load rating is higher than the weight of your loaded trailer. With that being said, I can not recommend that you drive 70-75 mph and go over the speed rating of the tire. Excessive weight and speed can cause premature wear, heat build up, and potential tire blow outs. For...

  • Recommendation for the Best Trailer Wheel and Tire Size for Highway Towing
    You are correct that many deck over trailers have lower height wheels and tires. The reason for this is to reduce the height of the deck for ease of loading and unloading and to reduce the propensity for the trailer to be top heavy which can be a factor that contributes to trailer sway. Trailer tires are not rated for high speed towing. As a general rule most trailer trailer tires and wheels are rated for 65 miles per hour depending on the manufacturer. The best way to select the size...

  • Should Trailer Tire Rated for 90 PSI be Ran Always at 90 PSI
    Trailer tires are unique in that they are designed to be inflated to their max psi rating when cold regardless of the load on them. This ensures you don't create excess heat which would cause the tire to fail over time.

  • Smallest Trailer Tire with Speed Rating Over 80 Miles Per Hour
    Eight inch trailer tires max out at 65 miles per hour. They are so small that at speeds above that they would have so many revolutions that they would get excessively hot and fail. Also, there isn't an 85 mph speed rating for tires. It goes from 81 (M rating) to 87 (N rating) and the highest that I have seen for a trailer tire is an M speed rating. To get to the M speed rating you would have to go all the way up to 12 inch tires and wheels such as # TTWSF48012C for a tire and depending...

    Yes, typically the tires are what dictate the speed rating. For example, the Kenda 4.80/4.00-8 Bias Trailer Tire # AM30020 has a speed rating of 65 mph so in theory this would raise the speed rating of your trailer.

    Your trailer sounds like it will work just fine based on the dimensions and weight you gave.
