If you change to a different size wheel and/or tire size, should you alter the PSI you run in the tire? For example, would a 215/45R17 tire on a 7" wheel (stock) require the same PSI as a 205/55R16 on a 6.5" wheel (aftermarket)? I'm just using these sizes as examples, so they may not be real, but it conveys my question. Should I still use the vehicle manufacturer's recommended PSI, or should the PSI be higher or lower?
