Wheels, Offset, and How to Calculate Fitment
When fitting aftermarket, or custom wheels, you should check for any clearance issues.
Incorrect fitment or Rubbing will wear out your tires, bearings, and cause other suspension components to fail or wear prematurely.
Offset is the measurement in millimeters from the wheel centre line to the wheel mounting face.
The Offset, or "ET" (Einpress Tiefe translates to Press Depth in German),
WARNING: Incorrect offset can seriously affect vehicle performance.
|Rim Measurements||Positive Offset||Negative Offset|
This stock 4.5" x 10" Mini Cooper S alloy wheel has a POSITIVE Offset of 35mm.
This Minilite 6" x 10" Mini Cooper S wheel has a POSITIVE Offset of 15mm.
This Super Trax 7" x 13" Mini Cooper S wheel has a POSITIVE Offset of 7mm.
This Alleycat 7" x 13" Mini Cooper S wheel has a NEGATIVE Offset of 7mm.
a wheel with NEGATIVE (-) 15mm OFFSET or ET would be shown as ET-15
