i already have 4 17" adr fuel rims. i wanna get the kumho 711s 235/45/17 cuz alot of people recommend them plus theyre cheap. the thing im worried about is fitment. my rims are 7" wide. does anyone kno if these tires will fit or do i need a diff size cuz i dont wanna make too much of a difference in the overall diameter causing my odometer and speedometer to be off. thx
