I'll have to look. They're 1760# tires hauling a 1979 Correct Cradt Ski Tique. Weight isn't a factor. I'm guessing they're old as heck since it' was always stored inside and is what came with the boat. The rip is about center of the tread and went almost to the sidewall but not past the treaded area. The steel belts look all mangled. I bought some TSC radials with wheels and replaced them both to get moving again. Damn it, ST is apparently 65 mph rated. Who drives 65mph any more? Double damn it, the TSC Tires are also ST rated I think. They shouldn't be able to make a trailer tire not rated for less than 85. Live and learn, next time it'll be a LT tire. According to opinions on RV forums it's the way to go for a realistically speed rated tire for a trailer. I don't want to be "that guy" in the right lane with his cruise set to 65 in a friggin 70.
