BMW Wheel Centre Cap Size Guide
AUTO HAUS CARBON • HELP & ADVICE
Choosing between 56mm and 68mm BMW wheel centre caps? Use the chassis guide below as a starting point, then check the cap fitted to your actual wheel.
Sizes can and do vary depending on which wheels were fitted from the factory. Replacement or aftermarket wheels can also require a different size. Always measure your existing centre caps and compare the rear mounting clips for 100% confirmation of the correct size. A model or chassis match alone does not confirm fitment.
How to measure your centre caps
- Measure the full outside diameter across the centre of the cap’s front face, edge to edge, in millimetres. Measure the complete cap, rather than just the logo insert.
- Where possible, remove an existing cap carefully and check its rear retaining clips, mounting diameter and depth against the replacement product’s photographs and dimensions.
- Select the matching 56mm or 68mm option only after checking both the face size and mounting. If the cap is missing, or the measurement is unclear, contact us with wheel photographs and any wheel or cap part number before ordering.
Find your BMW model and chassis
LCI means facelift. Where an LCI version of a listed chassis is fitted with the same wheel and cap mounting, use the same guide size, but still measure. A dash means no size is listed in that column; it does not mean the model cannot use centre caps.

Standard and floating centre caps
The guide applies to selecting the nominal diameter for both standard and floating BMW centre caps. Floating caps must also have sufficient rear clearance for their mechanism; check the product dimensions and your wheel before fitting.
