Well, I must drive like a grandma because the car just hit 9900 today and has the origional tires, plus since it is actually my dad's car (the horrible truth, although I drive it more than he does) when he drives the car it spends most of its miles on the freeway.
I'm starting to get a little bit of squeling from the rears driving around curves in the mountain, but it still grips well, I'm just worried that I'll find out about treadware by snap oversteer.
