Loosen lug nuts on all four wheels slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and tires from the vehicle.
Rotate the tires according to the manufacturer's specifications (e.g., front to back, side to side).
Reinstall lug nuts and torque them to the manufacturer's specifications (usually around 80-100 ft-lbs for Highlander).

3. Wheel Alignment

Tools Required: Alignment machine (available at tire shops).
After tire rotation, take the vehicle to a professional alignment shop.
Ensure the alignment is adjusted to factory specifications for camber, caster, and toe settings.
Confirm that all adjustments are within the acceptable range set by the manufacturer.
