I've been running them on 22" Vossen's for ~20,000 miles. I'm very happy with them besides the noise which has gotten worse as time goes on. Performance wise they're great. Snow, heavy rain, hot & cold weather, etc.
I've been thinking of replacing them early (still have good tread depth) just because of how loud they've become. It's why I'm browsing the forums today - looking for new tire options
