The offset of a rim is the distance between the mounting surface of the rim and the centerline of the wheel. It is important to find the correct offset for your vehicle, as it can affect the handling, performance, and appearance of your car.
There are a few different ways to find the offset of a rim. One way is to look at the back of the rim. The offset will be stamped on the back of the rim, usually in millimeters. Another way to find the offset is to use a wheel offset calculator. These calculators can be found online or in automotive magazines.
