I have read many of the Venza reviews that are out there, and on several there were comments made about sacraficing ride comfort for the looks of a 20" wheel/tire package. Some suggested Toyota should have gone with an 18" package. I am not saying the critics are wrong, but I do not see how an 18" could possibly ride any better than the 20's. If it is possible then that would be "one smooth ride"! Does that mean that a 16" tire will ride better than an 18". I guess I need a tire expert to explain this one. I have never seen much (if any) difference in ride quality from one size to the other, but I have experienced big differences from one brand to the other. Any ideas on this?
