It seems like there was a big thread on trailer tires on Pirate. IIRC it came down to one good radial and one good bias. Whatever brand had the best bias, had the worst radial, and vice versa.
I've always been told "DO NOT use truck tires, ONLY use trailer rated tires if you want them to work right and hold up." Yet my real world experiences say otherwise. After the trailer tires are all blown out or tread falling off, I always end up with some type of truck tire to finish up the trip, or make the trip, then it's the only one that lasts.
