What indicates a flat tire during a pressure check?

A tire is considered to be flat or significantly under-inflated when its pressure is substantially below the manufacturer's recommended specification. Being 20% below this standard indicates a critical level of under-inflation, which can affect safety and performance while driving. Proper tire inflation is essential for maintaining control of the vehicle, ensuring adequate traction, and optimizing fuel efficiency. When a tire is 20% below the recommended pressure, it often leads to increased wear and tear on the tire, higher risk of blowouts, and can reduce braking effectiveness. Therefore, the threshold of 20% less than the manufacturer's suggested pressure serves as a clear marker for identifying potential tire issues that require immediate attention to prevent hazards on the road.
