How to Calculate Wheel Offset
What is Wheel Offset?
Calculates proper wheel offset to maintain steering geometry and clearance. Ensures wheels fit correctly without rubbing or damage.
Step-by-Step Guide
- 1Offset = distance from mounting surface to wheel centerline
- 2Negative offset pulls wheel outward; positive inward
- 3Calculate: centerline - mounting distance
- 4Verify clearance with suspension components
Worked Examples

Result
+40 mm
Common Mistakes to Avoid
- ✕Installing wrong offset without clearance check
- ✕Not verifying compatibility with existing suspension
Frequently Asked Questions
What happens with wrong offset?
Rubbing on fender/suspension, altered steering geometry, premature tire wear, poor handling.
Can I change wheel offset?
Yes; wider wheels with less offset push them out; requires suspension and brake adjustments.
