    17x7.5 Gramlights 57c

    hey what`s up guys. i don`t really have much experiences with rims..so i have a 17x7.5 gram lights 57c...but i don`t know the offset to the rims...the stickers are all f`d up so..it`s either +30 or +40...but not too sure which one it is...i need to get it replaced because there`s a crack all around one spoke...they were on the ep3 though, but which one would it be? +30 or +40?

    either one fits.. calculate it:
    1. measure the wheel width
    2. measure the backspacing (distance from inside lip of wheel to where the hub sits.
    3. do this calculation: Backspacing - (wheel width/2)= x
    4. convert x to mm and there is your offset
