Product specifications:Material: MetalGro weight: 0.40KgSpecification: 00Origin: ChinaProduct Introduction:1. Metal tire preure gauge, used for detecting tire preure in automobiles. Correct preure detection can increase safe driving, reduce tire wear, and reduce fuel consumption.2. When the tire cools down, measure the preure by preing and holding the tire valve with the tire nozzle until the pointer points to a high value and reads the preure.3. Based on the driver's experience and combined with road conditions and load capacity, make relatively accurate preure judgments. Safe driving productsInstructions for use:1. The vehicle needs to be parked on flat ground, and the tire preure must be measured when the vehicle is cold;2. Firstly, check whether the reading of the tire preure gauge is at the "0" position. If not, pre the button on the side of the tire preure gauge to reset it to zero;3. Remove the valve cover of the tire, align the preure tap of the tire preure gauge with the valve on the tire, and pre it vertically and forcefully. The speed of preing in needs to be rapid to avoid air leakage inside the tire;4. While preing the tire preure gauge with force, observe if its pointer is stable. After the pointer stabilizes, quickly pull out the tire preure gauge and read it; (Generally, stable tire preure readings can be obtained immediately)5. Determine whether the tire preure meets the requirements based on the tire preure requirements on the door side and the driver's experience; If the tire preure is too high, the tire preure gauge can be used for deflation; If the tire preure is too low, it should be immediately inflated to a safe tire preure and re measured to verify the accuracy of the tire preure;6. Reset the tire preure gauge to zero and cover the valve cap back;7. Check the tire preure at least once a month. Before proficiently measuring tire preure, it is recommended to take multiple measurements to ensure that the readings are correct!
