Have over 5000 miles on our Rainier tires. I'm not sticking up for them, that's just what they have. I will be changing them next year regardless, but so far I haven't seen any issues. I had a LOT of conversations with Adam / Tredit. They own the mold or something to those tires. Still relatively new. I have a thread somewhere on here with some of the email responses.
