Tire Rack is having a closeout sale on Hankook RS-2's. I just picked up a set to be put on the Mazda in April.
I should probably talk my grandpa into buying some rears for his Mustang GT. Max performance summer tires are huge overkill for him, but his current tires are summers and are almost shot. I don't believe in putting all-season tires on a sportscar that will never be driven in winter. I don't think he can do much better than $81 per tire shipped for 245/45/17's, summers or all-season's. That said, my poppop usually buys the cheapest used tires he can find for his cars, a practice I consider terribly unsafe.
