How to Properly Inflate Your Tires

Correct tire pressure is essential for safety, fuel economy, and tire longevity.

Steps

1. Find the recommended pressure — Check the sticker on the driver's door jamb or your owner's manual. NOT the number on the tire sidewall.
2. Check when cold — Measure pressure before driving or after the car has been parked for 3+ hours.
3. Use a quality gauge — Digital gauges are more accurate than pencil-type.
4. Inflate to spec — Add air in small bursts, checking frequently.
5. Don't forget the spare — Check your spare tire monthly.

Under vs Over Inflation

Under-inflated: increased wear on edges, poor fuel economy, risk of blowout.
Over-inflated: harsh ride, less grip, center wear.
