I'm at about 17K right now on my '04 18" Michilin Pilotsports. There's still plenty of tread on them, but I generally drive fairly light. I'm expecting to hit about 25-30K before replacing them.... although, when I put the car back on the road at the end of this month for spring, I'll probably tear them up pretty badly just out of excitement of not driving the car all winter.

 

So are you guys saying that the OEM 19" Potenzas are not directional and can be rotated side to side?
