Can a manual pump inflate car tires?

[EdenFitz]

Manual pumps can inflate car tires. Principle of the pump: The pump creates higher pressure inside than the tire's internal pressure, forcing air into the tire. Family cars generally use low-pressure tires with tire pressure ranging from 2.0-3.0 bar, while bicycle tire pressure is typically 3.5-4.5 bar. Therefore, a regular bicycle pump can fully inflate car tires. Typically, using a large pump requires 15-20 strokes to increase the pressure of a 195/65 car tire by 0.1 bar. A high-pressure pump is more efficient and requires less effort. Related information: Manufacturers usually recommend a tire pressure around 2.3 bar. Seasonal factors should also be considered: in winter, it's advisable to increase the standard tire pressure by about 0.2 bar; in summer, follow the lower limit of the standard tire pressure. For cars parked outdoors in summer, the pressure can generally be 0.1 bar lower than the standard to prevent blowouts due to high temperatures. Load conditions should also be considered: when unloaded, follow the lower limit of the standard tire pressure; when fully loaded, follow the upper limit.
