I've been doing some reading about the "chinese" tires that are coming with trailers and am a bit concerned. My trailer is 2012 (built oct 2011) and is running Mastertrack 225/75r15 tires. They have roughly 3000 miles on them and appear to be in good shape. I inspect them before each trip and make sure pressures are good. After all the reading I am nervous that I am asking for trouble if I continue to tow on them, but most of the post and info I have read is from years ago, nothing seems to be current. My question is I guess are the tires made of better quality now or are they still a ticking timebomb? Are there really that many problems with them or is it one of those things where a few people post problems but thousands run them without issues? Thanks!!
