Number 10: Check the age of your tires.... ...including your spare tire. Look for the tire identification number on the sidewall of the tire, which begins with the letters "DOT." The last four digits represent the week and year the tire was manufactured.

Check the owner's manual for specific recommendations for when to replace a tire. Some vehicle manufacturers recommend that tires be replaced every six years regardless of use.

Number 9: Check tire pressure.... ... and make sure each tire is filled to the vehicle manufacturer's recommended inflation pressure, which is listed in your owner's manual and on a placard located on the driver's side door frame (called the "B-pillar").
