Why need tire pressure gauge ? According to research, about 70% of traffic accidents all over the world are caused by tire problems. If the tire pressure is too low, it will increase fuel consumption and result in tire wear or a flat tire after a high-speed running for a long time. If the tire pressure is too high, it will reduce the tire grip & friction, affect braking. Meantime, it cannot prevent the sharp objects effectively, which causes tire blow out easily. Uneven tire pressure can affect steering and braking increasing chances of a traffic accident. Thus, it's significant to maintain your tire in good condition. How to use? NOTE: When Measuring tire pressure, the tire should be in a cooling condition. Step 1: Unscrew the lid of tire valve, which refers to the lid of gas nozzle on tire that used to inflate. Step 2: Fasten the air chuck of tire pressure gauge and compress on tire valve; then pinch the clip of air chuck till it perfectly connects to gas nozzle of tire. Step 3: The tire pressure gauge will show tire current pressure. Step 4: If the tire pressure is too high, press the trigger half way down and adjust to the appropriate tire pressure. Step 5: if the tire pressure is too low, connect air intake of tire inflator to an air compressor pump, then pull the trigger(switch) all the way down to inflate. Step 6: After measuring tire pressure, the LCD will turn off after 15/30 seconds automatically.
