Show me the steps to change a tire.
assistant
1. Park on a flat, level surface and make sure your vehicle is in park or in gear.
2. Place a wheel block in front of or behind the wheel diagonally opposite from the flat tire.
3. Loosen the lug nuts before jacking up the vehicle with a jack.
4. Lift the vehicle with the jack until the tire is about 6 inches off the ground.
5. Remove the lug nuts and flat tire, then place the new tire onto the hub.
6. Replace and hand-tighten the lug nuts.
7. Lower the vehicle and finish tightening the lug nuts (in a star pattern) with a lug wrench.
8. Double-check that the lug nuts are all tightened, and remove the jack and wheel block.
