I used to sell tires, and I can tell you that all trailer tires are crap. Didn't matter what brand GoodYear, Carlisle they all fail inside of 5 years. Don't buy in to that LT tires won't work on a trailer BS. I put LT 235/75/15 C load range tires on my trailers, my fathers trailer, my uncles trailer, 3 of my racing buddies trailers. Not one issue, not one failure. If the LT tires on my 3 ton turbo diesel tow rig don't go to crap every time I turn around, seems logical that they would work as well under the trailer, and they have.
Michelin
BF Goodrich
Cooper
Good Year = worst tire brand I ever saw, nothing but advertising and gimmics. Easily the highest failure rate of all the tires I sold.
Don't buy no name tires made in 3rd world countries.
