Tire Pressure and Tread

• The recommended pressure is on the placard inside the driver's door jamb and in the owner's manual, not the number on the tire sidewall (that is the maximum).
• Check pressure at least once a month, including the spare, when tires are cold (not driven for at least three hours).
• The TPMS warning light only comes on when a tire is significantly underinflated, so still check monthly with a gauge.
• Worn tread reduces grip, especially on wet roads.

NHTSA's quick check: place a penny in the tread with Lincoln's head upside down and facing you. If you can see the top of his head, replace your tires. Tires should be replaced when tread is worn to 2/32 of an inch, and built-in treadwear indicator bars show when you're there.
