The only reliable way to assess tire pressure is through a tire gauge, according to the American Automobile Association (AAA). Tires can appear normal while being either inflated or under-inflated.
Maximum Pressure Misconception:
The myth that the maximum pressure listed on the tire sidewall is the recommended operating pressure is incorrect. Maximum pressure indicates the highest pressure the tire can handle safely, not the ideal pressure for operation. Vehicle manufacturers typically list the recommended PSI on the driver’s side door jamb, not on the tire.
Temperature Fluctuations:
The belief that tire pressure remains constant despite temperature changes is inaccurate. Tire pressure can decrease by about 1 PSI for every 10°F drop in temperature, according to the Rubber Manufacturers Association (RMA). This can lead to under-inflation in colder months, which affects tire performance.
Larger Tires Require More Pressure:
The notion that larger tires always require more pressure can mislead drivers.
