How much should the tire pressure gauge inflate?

[VanGideon]

Tire pressure gauge generally needs to reach 2.5. Here is an extended introduction: Manufacturer recommended tire pressure: The tire pressure should be inflated according to the manufacturer's recommended value. The manufacturer's recommended pressure value can usually be found in the following places: vehicle user manual, label near the driver's door (B-pillar), drawer next to the driver's seat, or fuel tank cap door. Cold tire pressure: The manufacturer's recommended tire pressure refers to cold tire pressure. It is defined as follows: After parking for at least three hours or if the tire has not been driven more than 2 kilometers. If you can only measure the tire pressure when the tire is hot, subtract approximately 0.3 bar (=4psi) from the measured tire pressure to get the cold tire inflation pressure.
