I could have used this advice to check pressure yesterday. Wife called me at 7am this morning saying that her tire light lit up on her dash on her way to work. I was half asleep and told her I'd check it when she got home. But she works an hour away and drives 80mph for most of the commute so I got worried and drove to her office to check the tires. All four were at 32 psi. Door sticker says 35 psi. Topped all four tires off and the tire light light went out. At least it wasn't a flat tire.
