How much air goes in your tires?

Not the number on the tire. That's the maximum. Yours is on the sticker in the driver's door jamb.

The Just Right card

Too littleSquishy tires, worn edges, wasted gas
Too muchPumped to the sidewall max, worn center, less grip
Just rightDoor sticker number, checked cold, once a month

Huh, didn't know that: Tires lose about 1 PSI for every 10°F drop, and the tire light doesn't come on until you're about 25% low.

The dad joke
I told my tires to stop being so dramatic. They said they're under a lot of pressure.
Play the game
