I am curious how many full track days some of you A and B level riders are getting out of your Dunlop Sportmax Q2. Do you replace both as a set when its time to go or do 2 rears for every 1 front? I ride with quite a bit of lean angle and my front tire still looks great after 6 track days on a very technical track even as my rear tire looks to be going out real soon. I cant imagine riding another 5 track days on my front tire but it looks likes its in excellent shape. Does that tire really last that long?
