[Biturbos4] Re: Alignment

[Keman]

I've seen Pilot Sports do that on TT's. I always attributed it to lots of
highway miles on a multi-compound tire. PS's do not wear evenly on the
highway, you have to throw them into the corners a LOT to keep the edges
wearing at a 'normal' rate. What kind of tires are you running and what
type of driving do you usually do?
