10 CAR MAINTENANCE MYTHS YOU SHOULD STOP BELIEVING

False: 3 — Tire pressures don't matter as long as they're inflated

Just because your tires look properly inflated doesn’t mean they are. Visual checks aren’t enough—underinflated or overinflated tires can lead to poor handling, lower gas mileage, and faster wear. According to the NHTSA, nearly 28% of U.S. drivers have at least one underinflated tire.

Don’t rely on the maximum PSI listed on the tire sidewall—that’s the limit, not the recommended pressure. Instead, check the sticker inside the driver’s door or your manual for the correct PSI. Some cars even list separate pressures for heavy loads versus everyday driving.
