I put Si wheels on my EG some time ago, but i have always had the feeling that the tires are too big. I just got them done a discount, because I didn't have the money to get good tires, so I'm stick with the khumo's for now. anyways, the size is 195-55-15. i don't know what number refers to the profile of the tire, but it seems that this is the number for the tires that came on the factory Si wheels, and fit into the coupes better. they come with 14's (just the regular ones, not the si's) but my car comes stock with 13's. i'm wondering if i should go with a lower profile tire whenever I get a chance to redo them?
