Use your vehicle owner’s manual to determine the proper procedures for changing your tires. Generally, those procedures will include: 

• Loosening of the lug nuts.
• Then, jacking up the vehicle.
• Removing the flat tire.
• Installing the spare tire and hand tightening the lug nuts.
• Lowering the jack and vehicle.
• Tightening the lug nuts with a lug wrench using a “star” pattern. 

Your owner’s manual will also tell you the location and operating procedures for your jack, the proper placement for your jack, and the location of your spare tire.
