those of you running 17's what tire size are you running?
looks like the coopers went up 30 bucks a tire and I can get good years in 17's for 110 bucks plus 60 bucks a rim and it is almost a wash.
Depends on the car I'd use 235/55-17 tires on a B or E body car. That should be roughly the same as the biggest tire that the factory put on a B or C body car. For an A body car you might need to go a bit shorter.
