You already know your rim dimensions, for example 8x18 ET45 with 5x112 bolt pattern? Choose the rim diameter in inches above and then refine by width, offset (ET), bolt pattern, centre bore and brand. “8x18 ET45” means 8 inch rim width, 18 inch diameter and 45 mm offset; “5x112” is the bolt pattern (5 bolts, 112 mm).
Rim size is only the first step: whether a rim is street-legal on your vehicle depends on the ABE or parts certificate and your key numbers (HSN/TSN). For a vehicle-specific approval, use our configurator with vehicle selection.
