A tire inflator is a compressor used to inflate the tires on your car. Use compressed gas pumping to fill the tires with pressure. If you drive a car, a cheap little blower. If you want to squeeze your car tires, as well as inflate balls and bike tires, this is all you need. Canned tire inflators are disposable devices that aim to provide a quick fix. These devices seal the flat tire and then inflate it again with compressed gas, providing sufficient pressure to allow the vehicle to be driven for a short time at low speed.
