If you want a GOOD trailer tire, track down a set of Goodyear ENDURANCE tires. The ONLY USA made 15" trailer tire out there. I run them on all of my trailers, 205/75-15, 225/75-15 and 235/80-16, and have never blown one out. Every chinese tire I've run has eventually failed by either blowing out or separating at the edge where the sidewall meets the tread. There are quite hard to find, but Amazon found me 4 last month for my car trailer. I was running Goodyer Longtrail truck tires (225/75-15) until I aged them out at 10+ years and some growing sidewall cracks. I threw some chinese ones on since they were all I could get on short notice, but I had to replace them after a year for sidewall separations.
