It should be noted

1st Alignment Centre recommends the following:
For all vehicles where an increase in ground clearance is NOT desired, then the percentage difference should not exceed 5%
Large increases in tyre diameter may:
- Not fit the vehicle. Larger tyres should be tested for clearance when suspension is fully articulated and steering is fully locked in both directions.
- Require bodywork to be cut/trimmed by a professional.
- Require a change to the final gear drive ratio
