How do I get correct wheel fitment?
Put simply, to find if your wheels will fit your car, measure the distance from your wheel’s center point to where it is mounted. This is the offset. Add that to half your wheel’s width to find the back space and subtract it to find the front space. Compare this to your wheel well to see if it fits.
