I am gonna get flack for this post, but anyways, so I was a "Goodyear Man" when it came to trailer tires also. My dad always bought Goodyear and I can only suspect Goodyear made really good trailer tires long ago. Anyhow, every Goodyear , Class C I have bought, every one, 4 now in a row, blew out under high load, high stress conditions. We are talking long haul 1000 mile trips on my 17 ft , only 3000 lbs travel trailer. High heat, in summer, just spectacularly blew out at highway speeds. I moved up to class D generics and never had another problem. I cannot recommend a brand on "Generics" just go with Class D or E , 8 and 10 ply tires, steel belted. They won't blow out, haven't had one since and even higher loads now with the new toy hauler. However, they are noisy, and thats the trade off, like an 18 wheeler. I stopped buying class C. You can of course get those in a name brand but they will cost, and I just have too many vehicles now. I have spent $500 on 3 batteries just in the past 6 months cuz of all the toys I have. I wanna say DOT commercial rated Class D about $75 each, probably about $50 in 15in if its a small trailer. If you like Goodyear, about 15 years ago, I was able to order the Class D 15in trailer tires Uhaul has custom made for them from Discount Tires. They say on the tire Goodyear, "Property of Uhaul". Those are way awesome tires, and look like they belong on a truck in the 50's. Uhaul is such a big company they have Goodyear make them super long life tires for all their trailers. Lasted 10 years on a trailer I had, but they were expensive.
