I have a pair (2) Michelin Pilot Sport PS2 tires in 225/40/18 size. These tires are used however appear like brand-new. The tread depth I have not determined yet but they are extremely near to new. These tires cost $273 each on tirerack.com and much more locally. They are also the N3 rated for Porsche vehicles. The speed rating is (Y) so these can manage any speed except a Bugatti. They were replaced just recently with a whole set of tires so these are additionals that I wish to offer. I am searching for $375/obo for the pair. These are a few of the very best tires you can purchase. Summer use only, not all period. E-mail for even more details or for concerns.
