I just bought a civic exi 2002, the stock trye size is 13 inches, would it be ok to change it to 15 inches without considerable impact on mileage and suspension? I need to raise the ground clearance. Please advise if its ok to change 13 inch rims to 15 or 14 for that matter. I am also confused as to why is my car having 13 inch stock size as opposed to other civic exi 2002 which mostly have 14 inch rims.
