I’ve had the Box going on 2 years now, and it’s looking like I’m finally going to need to start thinking about tires. She came (used, a 2001 S) with Dunlop SP Sport 9090s all round, which I have been pretty happy with. They seem to handle well and I can’t complain about the tread wear: have gotten about 23K on the rears, which seemed really good to me, considering what I have read here on 986forum. (I drive in spirited fashion, though only breaking the rear tires loose from time to time; haven’t done the autocross thing---yet.)
My question: Even though I have been relatively happy with those tires, I am considering others as well. However, common wisdom seems to indicate one shouldn’t mix tires of different brands. Does that mean I just have to kiss off the thousands of miles of tread left on the fronts? I don’t really want to store them for some possible, unknown future use---I really don’t have the space. Just how bad it it to mix tires?
