I definitely will buy new ones for next year as I am switching wheel/tire sizes. Do I need to move that up to this year? Here's the background. I only made four passes last year due to COVID and both times I went to the track someone blew up and oiled down the track. I haven't been out this year yet so there's still plenty of tread, but this is the fourth season. Since the local track shut down I don't want to drive 1.5 - 2 hours and not be able to hook.
