The question of which rim fits which car is crucial. There are two ways to find the right rim size. The easiest way to find out which dimensions are suitable for your car is to look at which size is currently mounted. The rim dimensions are often engraved on the back of the spokes. The key factors include the rim width in inches (e.g. 8.5), the inch size (e.g. 20), the offset in mm (e.g. ET38) and the bolt circle (e.g. LK4x100). It also never hurts to take a look at the vehicle registration document, as there are often other approved dimensions under point 22 that are guaranteed to fit the car. Another option is our rim configurator. All you need is the HSN and TSN number from the vehicle registration document. These can be found under points 2.1 and 2.2. All suitable rims are then listed. Before you order a new rim, you should always look at the rim report and find out about possible conditions. You can find a detailed explanation of the reports in our blog Reports explained
