What is the effect of putting a 225/45/17 tire on an 8" wide wheel as opposed to the stock 7.5?
Any reason to consider 235/40/17, knowing that the overall diameter would be 2% less?

The 8" wheel will slightly stiffen the sidewall of the 225, and give a little better steering response. For a 225, the 7.5" would be OK, but the 8 would be better. I would not put a 235 on the 7.5" wheel, but many people do.
