Read the inner ring of the air pump pressure gauge, with the normal value ranging from 2.2 to 2.4 bar. The method for checking a car tire pressure gauge is: Align and press the measuring end notch of the tire pressure gauge with the tire valve stem. At this point, the pointer on the tire pressure gauge will deflect, and the indicated value is the inflation pressure of the tire. Alternatively, the gauge's indicator rod will be pushed out under air pressure, and the value displayed on the rod is the tire's inflation pressure. Methods for tire maintenance include: 1. Regularly remove stones stuck in the tire treads; 2. Avoid exposing tires to direct sunlight; 3. Frequently check tire pressure by referring to the normal pressure values listed on the inside of the vehicle's fuel tank cap and adjust accordingly; 4. Pay attention to suspension maintenance; 5. Periodically inspect front wheel alignment.
