Too Afraid to Ask

PSI is a way to say how hard air is pushing inside something, like your car tires. It tells you if the tire has enough or too much air.

Technical Definition

PSI stands for pounds per square inch, a unit of pressure commonly used to measure tire inflation and other pressures in automotive contexts.
