Can a bicycle pump be used to inflate a flat car tire? Household cars generally use low-pressure tires with a tire pressure ranging from 2.2 to 3.0 bar, while bicycle tire pressure is typically between 3.5 to 4.5 bar, which is higher than that of car tires. Therefore, using an ordinary bicycle pump to inflate a car tire is entirely feasible as long as the valve stem types match. The pump operates by drawing air into its storage chamber through a pulling motion and then injecting or replenishing the required air into various tires and some balls through a pushing motion. When the outer tube is lifted, air enters the pump through small holes on the middle sleeve at the bottom of the outer tube. Then, when the handle is pressed down, the air passes through a one-way valve at the top of the inner tube, enters the inner tube of the pump, and flows through the hose into the tire's valve.
