What is the appropriate standard tire pressure for cars?
2 Answers
The standard tire pressure is generally between 2.4-2.5 bar. If the tire pressure is too low, the contact area between the tire and the ground will increase during driving, causing the internal temperature of the tire to rise and potentially damaging the tire. Every car should be equipped with a tire pressure monitoring system to keep track of the tire pressure. The specific introduction of tire pressure monitoring is as follows: Direct tire pressure monitoring: This system uses pressure sensors installed 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 tire pressure data for each tire. The system will automatically alert when the tire pressure is too low or if there is a leak. Indirect tire pressure monitoring: This system works by detecting when the pressure in a tire decreases. The weight of the vehicle will cause the rolling radius of that wheel to become smaller, leading to a faster rotation speed compared to other wheels. By comparing the speed differences between tires, the system can monitor tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure.
As a seasoned driver with years of experience, I believe tire pressure shouldn't be generalized. It's best to refer to the vehicle manual or the label on the driver's side door frame, which provides precise recommended values, typically between 30 and 35 PSI. Low pressure can cause excessive wear on the tire edges, increased fuel consumption, and even potential blowouts; high pressure leads to rapid center wear and unstable handling. I make it a habit to check monthly using my own pressure gauge when the tires are cold to ensure safety. Don't rely on gas station gauges—they're often inaccurate. Proper long-term maintenance also saves fuel costs and extends tire life, killing multiple birds with one stone.
