How to check tire pressure without a tire pressure monitoring system?

[ArcherMarie]

Without a tire pressure monitoring system, you can check tire pressure through methods like pressure sensors and visual inspection. The specific methods are introduced as follows: Pressure sensor method: Install a pressure sensor in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. The system will automatically alert when the tire pressure is too low or there is a leak. Visual inspection method: Observe the height and flatness between the two tires. Inflated and uninflated tires differ in width and contact area with the ground. An uninflated tire will have a larger contact area than an inflated one. If the steering wheel pulls to one side or the car drifts in a certain direction while driving, it could also indicate abnormal tire pressure due to unequal torque on both sides.
