Remove the lug nuts completely and take off the tires.
Rotate the tires according to the manufacturer’s recommended rotation pattern.

3. Wheel Alignment

Set up the vehicle on a wheel alignment machine.
Adjust the alignment settings according to manufacturer specifications.
Make necessary adjustments to the camber, caster, and toe angles.
