8. Raise the Vehicle With the Jack
To prevent the jack from settling under the weight of your vehicle and coming off balance, place a small cut of 2×6″ wood beneath it before attempting to raise your vehicle. This tactic is especially helpful on asphalt.
With the jack properly positioned, raise the vehicle until the flat tire is about six inches above the ground.
Never put any part of your body under the vehicle during or after raising the vehicle with the jack.
