i have st-200 wheels, they came with stock 215-45-17 pirelli p6000s well damn those tires they lasted me 16,000 miles on a ZETEC! so we know it wasnt from burnouts. i have recently bought a set of 225-45-17 michelin pilots and the tire covers the wheels much more, fills the wheel wells better, steers better, absorbs shock better, i must say i will stay with this size for quite some time im sure
