i called the tire shop yesterday to get a price on new trailer tires and he said $65 a piece and up, according to what brand. he also said they were passenger car tires. what's the differance in trailer tires and car tires? i saw some at walmart for $35, same size. will these work or should i try and find some trailer tires? i've got Titan tires, st 155 80 r13, on the trailer now.
