I know according to the tire shops computers that the largest size tire to fit on my stock rims are 225/50/15 but is that it? Can't I go with say 225/55/15 or a 60 series in that size? What is the largest 15" tire I can put on without having it rub? Has anyone done this? What's your tire size? I know someone has put the Probe GT's rims/tires on the MX6, what is the MX6's tire size equivalent to the Probe GT's tire size? I'd like to fill in the wheel well abit with out lowering the car or having the tire rub.
