These tires came as OEM for my 2011 WRX and have 40k miles on them already, however it is showing no signs of wear. I'm trying to wear them out so I can switch to a UHP A/S tire, such as the Continental DWS, however it's not happening soon enough.
Being a summer tire, I'm a little weary on driving it during the wintertime. Last year's winter was mild and I really didn't get a chance to see if it would be OK. But to sum it up, this tire has amazing treadwear.
