Tire Size Adjustment

Why the Correct Tire Size Matters The right tire size is crucial for safety, driving comfort and efficiency. Changing the tire size on your Ford is not only an aesthetic decision but also a technical adjustment that requires precise calculations and settings. Adjusting the Vehicle Electronics By adjusting the vehicle electronics, the new tire size is optimally integrated into your Ford's system. This ensures your speedometer shows the correct speed. Our precise calculation method provides a reliable adjustment. How we work: • Wheel circumference measurement: the new tire circumference is measured accurately and compared to the original. • Electronics adjustment: speedometer and other vehicle systems account for the new tire size. • Test drives: accuracy is verified after the adjustment. Your benefits: • Precise speed display – especially important for speed limits • Improved driving dynamics and fuel efficiency • Greater safety Approvals and Registration After changing the tire size, a TÜV (Technical Inspection) approval is required in Germany. It confirms that the modifications comply with legal requirements. We provide you with a document containing all necessary technical data and calculations as proof for the TÜV. The changed tire size must be registered in the vehicle documents after a successful inspection so the modifications are officially recognized. Also inform your car insurer about the change. Important: driving with non-approved or unregistered tire sizes can result in fines, penalty points and revocation of the operating license, as well as insurance problems in the event of a claim.
