The closest radial tire size we offer to your 4.80-12 bias ply trailer tire would be the Karrier S-Trail ST145/R12 Radial Trailer Tire # AM10140. This tire will be about an inch taller and wider than what you currently have.

You will need to make sure your trailer has enough clearance for this.

I attached a couple FAQ articles on trailer tires for you to check out as well.

Answer 7

Increasing tire width will not really benefit you in any significant way. You would see a slight increase in stability, but if the trailer already rides pretty straight, you may not see any improvement. The 5.30-12 tires would also make the trailer…

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.

We can help you find the seal you need, but the part number you mentioned does not match anything we offer. Can you get me the inner and outer diameters of the seal? With that I can see what we have that matches.

Answer 12

The Loadstar trailer tires are made in both China and Taiwan. You will want to check the inside of the tire and if there is wear also on the inside it will be from low tire pressure. Always make sure to inflate trailer tires to the maximum psi rating…
