Keep Tires Properly Inflated for 3% Better MPG

The Problem

You never check tire pressure. Under-inflated tires waste gas and wear faster.

The Hack

Check tire pressure monthly with a $3 gauge. Fill to the PSI listed on your door jamb sticker. Check when tires are cold (before driving).

Why It Works

Under-inflated tires have more rubber touching the road (larger contact patch), increasing rolling resistance. The engine works harder to move the car, burning more fuel with every mile.

Pro Tips

• Correct PSI is on the door jamb, NOT the tire sidewall
• $3 gauge at any auto parts store
• Most gas stations have free or $1 air
• Proper inflation also extends tire life by 25-30%
