I got really into AutoX this last year and definitely did quite a number on my street tires (not to mention realized just how much I could benefit from race tires). I'm upgrading to some 17" wheels for street use come spring and I'd rather not rage those the way that I did my previous tires.
So my plan right now...
Get some 17's for street use.
Keep my stock 16's with race tires mounted in the summer and snow tires mounted in the winter.
I realize that the stock 16's are pretty narrow for race tires (16x6.5 I believe)... but I'd think with the race compound tires it would still be a huge step up -- and I'd rather not have to buy another set of wheels just for that use.
