I've got a set of rota gt3 its 15" x 7" I was wondering what size of tires should I get? Thanks..

 

im assuming from your name that you have a 5th gen civic hatch like myself you are going to want 205-50-r15 or 195-50-r15 tires if you are really slammed go with the 195 but if not the 205 is a little wider and looks better IMO
