Not a dumb question at all. The answer is yes.
I just threw away the horrible Goodyear Tourings that came with my 19 Accord. I bought it new in March of this year and between lack of protection for the rims and their dismal wet performance and treadwear, I replaced them at 17,900 miles with a set of 245/40R19 Vredestein Quatrac Pros. They fit perfectly with no rubbing anywhere and the sidewalls stand proud of the rims by a couple of millimeters.
I'm thinking about purchasing the same tires and size. Is there any noticeable difference in the ride or noise?
