This is the first set of NT01s I've used and not sure how much further I can run them. Just finished my 9th track day with these, so I'm curious if anyone can give some feedback on how many laps they still have. I hired a pro coach for my next event and don't want to push having a tire issue if they are that close. Btw, I know there are faster options out there for tires but not really looking for this conversation to go down that rabbit hole. Thanks.
