Burning up tires is half the fun. Now that I'm running R-comps, I have a set of wheels with tires for competition only. I figure a set of tires per season.
It comes down to "You have to pay to play"
But tires for the focus are relatively cheap. You can run 15" wheels, and 15" tires are cheap!
I treat tires as expendable, kind of like gas or oil:D
