I too wanted to look at 18 in wheels, but you will find that your selection of 17 in tires is much better and they have a larger diameter (335/35/17 vs 335/30/18). Those Pilots may be on sale now, but down the road they may have you because of you available choices. This all assumes you wanted 335 width. For smaller widths, the choices increase.
