A foot pump is a simple device for tyre inflation. It may come in handy when you cannot power up an electric compressor due to faults in the car electrical system or breakdown of the cigarette lighter socket. This mechanical device is usually activated by pressing the pedal. The pedal is connected to the cylinder which moves relative to the piston. When pressing it, air is compressed and pumped into the tyre through a hose.
Foot pump: 7 important facts
- In most cases, the devices used for tyre inflation are of a piston type. Inexpensive models contain one piston. It this case, much time is required to achieve the needed result. Nonetheless, such accessories are quite suitable when you need to pump a tyre of a compact or midsize car.

- The models offered in the catalogues differ in the length of the hose through which air is supplied. For instance, this value can be 55 or 60 cm.
- You can buy a foot pump with a built-in flashlight to facilitate working at night time.
