The right pressure makes tires last longer, ride better and grip better. Here is what to run and when to change it.
Where to find the right number
Use the placard on the driver door jamb, not the number on the sidewall. The sidewall number is the maximum the tire can hold, not what you should drive on. Staggered cars often list a different pressure front and rear.
New wheel or tire size
If you plus-sized or switched to an XL tire, the door placard may not match anymore. XL tires typically need a few psi more than standard-load tires to carry the same weight. Check the tire maker's load-inflation table for your size.
Check it right
- Check once a month and before long trips.
- Check cold, before driving or after the car has sat a few hours.
- Pressure drops about 1 psi for every 10Β°F drop in temperature, so check when the weather turns.
- Low-profile tires look full even when they're low. Use a gauge, not your eyes.
Track days
Pressures climb as tires heat up. Many drivers set cold pressures a little low and check hot pressures between sessions, following the tire maker's track recommendation. Reset to street pressure before driving home.
Too low causes heat and sidewall damage. Too high wears the center and cuts grip. Questions? Ask our fitment team.
