1. CHECK TIRE PRESSURE MONTHLY
Even if your vehicle is equipped with a Tire Pressure Monitoring System (TPMS), check your tire pressure with a gauge when they're cool at least once a month and before every long trip. Air pressure enables the tire to support the load so proper inflation is critical.

2. MAKE SURE THE AIR PRESSURE IS CORRECT
Find the vehicle manufacturer's recommended air pressure on the tire placard. This can be found on the door or door jamb, glove box, trunk lid or fuel door.

3. CHECK THE TREAD DEPTH
Do the "penny test." If you can see Lincoln's head then it's time for replacement. Tires should be replaced when the tread is worn down to 2/32nds, or 1/16."
