I am thinking of getting P225/55R-17 or P225/60R-17 size tires. These have a bigger diameter than the P205/65R-15 my car came with. Are there any issues with doing this, other than the speedometer being off a little? To keep the diameter the same with 17 inch rims, I would have to use P225/50R-17 or similar, and those tend to be more expensive, and probably somewhat harsher. Not to mention, the g3 wheel wells seem a little oversized with the standard tire size.
