How much psi should I inflate my car tires to?
2 Answers
Before inflating the tires, the front tires should be inflated to 2.0 to 2.3 psi, and the rear tires should be inflated to 2.2 to 2.5 psi. If you want to know the real-time tire pressure of your car, you can check it through a tire pressure monitor. Currently, most cars are equipped with a tire pressure monitoring function, which can monitor the tire pressure and temperature in real time and display the tire information on the tire pressure display interface of the combination instrument. When the tire pressure is abnormal, a tire pressure alarm will be triggered. If the original car is not equipped with this function, it can be installed later, or you can equip a tire pressure gauge to measure the tire pressure regularly.
As an experienced driver, I think tire inflation is quite crucial. Generally, the standard tire pressure for ordinary sedans is between 30 and 35 PSI, but this value isn't fixed—it depends on your specific car model. I recommend checking the owner's manual or the label on the side of the door first, as it's clearly stated there. The most accurate measurement is when the tires are cold, meaning you should check them after the car has been parked for at least three hours, because hot tires expand and give inaccurate readings. If the pressure is too high, the center of the tire wears out faster; if it's too low, fuel consumption increases and there's a risk of a blowout. Once, I drove on the highway with low pressure, and the car felt unstable—it was really scary. I usually check the pressure once a month with a simple pressure gauge. If your car is often fully loaded or carrying luggage, the manual will specify that you should increase the pressure a bit.
