I want valuable advice

There isn't a good tire in the 15" size, finally upgraded to 16" with LT tires on my last 5er before I finally sold it. I had 11 Maxxis 15" E rated failures during 80,000 miles of towing. Changed over to 16" and no more problems during the next 30,000 miles of towing. I just had my first failure on my car trailer with 14" Maxxis so replaced with Kumho Radial 857 http://www.tirerack.com/tires/tires.jsp?tireMake=Kumho&tireModel=Radial+857 with the Q speed rating. Thought was if the tire is rated for high speed vs the ST of the Maxxis it should be a better tire. Good luck, most trailer tires are junk. Even our local tire dealer will no longer sale trailer tires. Also our local Costco will not honor the warranty. They will sale them but tell you upfront if you have a failure you have to deal with the manufacture directly.
