Drove home from track day- fealt like I had two square bricks for rear wheels. I clean off the inside of the rims as melted rubber can unbalance the wheel before I leave the track. When I pulled tires at home to rotate and change pads noticed I had 1/8"- 1/4" built up rubber on inner 1/3 of tire (not on inner shoulder). I took an autobody - 15 tooth flat body file- and shaved off the excess rubber that was clearly not original to Pilot Super Sports. Took my time to not damage tire- left about 1/16" built up rubber and figure that will just wear off pretty quick. Spent about 45-60 minutes per rear tire. Test drive- all OK - ran smooth was happy with results. Tires 16 months old with 18K miles and 12 track days-one more track day at The Glen this season- will do a new set of PSS in spring.
Not sure if how you guys deal with excess rubber but this seemed to work good- I just stayed away from the actual tire.
