How to Check Tire Pressure?
2 Answers
Currently, many vehicles are equipped with tire pressure sensors that monitor the internal pressure of the tires. The tire pressure is displayed directly on the dashboard, or it can be measured using a tire pressure gauge. The specific introduction to tire pressure monitoring is as follows: 1. Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alarm. 2. Indirect Tire Pressure Monitoring: The working principle is that when the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the speed difference between the tires, the system can monitor the tire pressure. The indirect tire pressure alert system actually relies on calculating the rolling radius of the tires to monitor the pressure.
To be honest, I make it a habit to check tire pressure before every drive because it's crucial for safety. Low pressure increases the risk of blowouts, while overinflation reduces traction. The process is simple - just buy a basic pressure gauge for a few dollars, or use free tools available at gas stations. Park the car for at least an hour to let tires cool before checking, as hot tires give inaccurate readings. Then remove the valve cap, press the gauge onto the valve stem, and check if the reading (needle or digital display) falls within the recommended range. You'll find the recommended pressure on the driver's door jamb sticker or in the owner's manual. I check monthly since neglecting this leads to premature tire wear and even increased fuel consumption - definitely not worth it. I also remind myself to adjust pressure during seasonal temperature changes when fluctuations are common.
