What is a tire pressure gauge?
1 Answers
A pressure gauge is an instrument used to measure air pressure, among which a tire pressure gauge is specifically designed for measuring the air pressure in tires. It consists of a gauge head, piston, main spring, etc. The gauge head has only one pressure measurement port, featuring a simple structure, small range, high accuracy, and ease of use. It is suitable for measuring tire pressure in small vehicles such as micro cars and motorcycles. Place on level ground: The vehicle should be parked on level ground, and tire pressure must be measured when the tires are cold. Remove the valve cap: Remove the tire's valve cap and press the measuring nozzle of the tire pressure gauge vertically onto the tire's valve stem. The pressing speed should be quick to prevent air leakage from the tire. Check requirements: Compare the measured tire pressure with the recommended pressure listed on the vehicle's door panel and consider the driver's experience to determine if the tire pressure meets the requirements. If the tire pressure is too high, the gauge can be used to release air. If the tire pressure is too low, immediately use an onboard air pump to inflate the tire to the safe pressure level and re-measure to verify the accurate pressure. Inspection cycle: Check the tire pressure at least once a month. Before becoming proficient in measuring tire pressure, take multiple measurements to ensure the readings are accurate.
