i know this sounds like a thread for the tires & wheels section, but i'm posting it here for people who have experienced this on the track.
my stock re050's in the back are getting pretty worn out (maybe 2mm tread depth left) and it seems like there's less grip than when they were new. this is contrary to what some guys on trackhq have reported for other tires. they say that their tires pretty much retain the same amount of grip until the treads are completely gone (and advocate driving them until they're completely bald).
is it my imagination that my re050's are less grippy or does anyone else have the same experience? i was going to do one more event on them, but i dont want to get out on track and then find that i have no grip left.
