Had to replace all 4 camp trailer tires this year after finding out the hard way they were rotted (blew 2 in 3 miles on I15). I know its recommended you need to put sun shields on them but if you stop and think about it, you dont really do that for your automobiles do you? Are trailer tires just that much more inferior to automobile / truck tires or is it the lack of frequent movement that is hard on them?
