Trailer Tire Recommendation for Size 4.80-12 that Can do Highway Speeds

Question

Question:

I have 480/4.00 -12 four ply rated 4 lug tires on trailer. Trailer weighs 250lbs. Max trailer load 1100lbs. 2 kayaks and storage box is what my load is. About 180lbs. On tire sides says 60mph max. With such a lite load, can I drive 200 miles on highway at 70mph a few times a year? Harbor Freight tires. Thanks,

I do have a great solution for you, but if you exceed the speed rating of a trailer tire it will get too hot and will very easily fail. I can't safely recommend you exceed the speed rating of your tire by 10 mph for 200 miles.

Instead the tire part # TT48012C is a 4.80-/4.00-12 tire like you need but with an 81 mph speed rating. This will easily let you cruise at 70 mph.

The radial tire will run cooler with prolonged use on the highway so if this is going to make up the majority of the use then that is what I recommend using. The greatest chance for failure will be out on the highway as pressure and temperatures…

Answer 10

What you found is a DOT number and not a speed rating. I was able to figure out which tire you have and it's a Loadstar 4.80-12 that has a 65 mph speed rating. In this size we have a tire that can go 81 mph as part #TT48012C.
