I'm by no means a tire expert. Looking for feedback if the pics below are normal tire wear or something more (alignment or tire issue).

I'm driving a 991.2 GT3 with Sport Cup 2's with about 7000 miles and 7 track days on them this summer. I'm new to track so don't think I've been hitting the tires hard. I'm running them on the track at 26 cold (all round) and aim for 35 hot all round. My last 3 track days have been at Thunderhill west (CCW) with the rest being at Sonoma. Generally street driving is on twisting roads around the Bay Area (33F/36R pressures).

I've noticed the wear is most obvious on the front left (drivers), with minor but similar wear on the real left (drivers), the passengers side front and rear don't have this issue. I've also noticed a fast vibration at corner #10 at sonoma, it's a fast right turn dog leg onto the back straight.

Any advice? Is this normal and I should not care, is this an indication that I need toe in/out work done? Am I a sh*t driver and need to understeer less or is there something wrong?


Notice the ridges on the leading each of each block.. This is the front drivers (arrow is direction of rotation)

A few more pics of the same tire as above...

It looks like your nice sticky tires are picking up rubber off the track.

Those look pretty damn spectacular for 7 track days! Especially if you are running stock alignment.

Lot, thanks guys. Guess my setup is pretty good and don't have much to worry about. I have one more track day left this season so will push these for one last time in November, then get some new rubber over the winter.

They look normal for that kind of use and mileage.
