How to Check Tire Pressure — Step-by-Step Guide (With PSI Chart for Every Car)
How to check tire pressure correctly in 7 steps — with the exact PSI for your vehicle type, how to read all 3 gauge types, TPMS explained, temperature correction guide, and what over or underinflation actually does to your tires.
How to check tire pressure: Park on level ground, wait 3 hours after driving (cold check is most accurate). Find your recommended PSI on the driver’s door jamb sticker — not the tire sidewall. Remove valve cap, press tire gauge firmly and squarely onto valve stem, hold 2 seconds, read PSI. Compare to door sticker. Add air with compressor or release with the gauge pin. Every 10°F temperature drop = approximately 1 PSI loss — check every season change.
