This is my second set of F1s, and they are going to need replacing in the next 6-9 months. I've been doing hill driving for autocross practice, autocross, drag racing and some highway driving to and from events, and they've performed really well for a street tire. In autocross I won my division on this tire in pouring rain and hail. At the drag strip the car hooks up almost as well as with drag radials in these tires. I would definitely get them again, except I just saw the price increase... on 2/20/10 I paid $233 per tire, and now they're $326, a WHOPPING 40% INCREASE in 2 1/2 YEARS!! That sort of price increase is way too much, and I don't know if the tire fund can handle it. Goodyear may have lost a customer on this one.
