Sorry, resurrecting this thread, but I think it's relevant...
Has someone worked out the formula for maximum wheel/tire size with respect to stock wheel well clearance and lowering? I see a couple tire size recommendation s here based on how much the car is lowered, but would be nice to have a rule of thumb to work with. Figured into this rule would be how much clearance you need to leave for suspension travel, turning, handling characteristic s. Anyone?
