I am looking to change my stock 17 inch rims, for 20 inch rims, but i want to know if the will rub in the back or mess up the ride quality.. i know it messes it up if the car is lowered but at stock height does it make a difference that you will feel. besides the bumps on the road.

and in that case can i get a larger and thicker tires to fix that problem.

If you stay withinan inch or so they will not rub in the front, but ride quality will be noticeably different, but the car will look better.
