wheel changing

Changing a defective wheel involving: stop the car on firm, level ground and put on the handbrake; turn on the four-way warning light; put a chock against the wheel in the opposite corner to prevent vehicle movement; place a warning triangle or flare a short distance behind the vehicle; loosen the wheel bolts or nuts while the wheel is still on the ground; jack up the car so that the wheel is no longer on the ground; remove the nuts or bolts; pull the wheel off; put on the spare or the repaired wheel (you may have to raise the car a little more since the flat tire sat lower on the ground); tighten the bolts or nuts evenly, giving them a final tightening once the jack has been removed
