What is the normal tire air pressure?
2 Answers
Tire standard pressure: Standard tire pressure: 240 to 250 kPa; Reinforced tire pressure: 280 to 290 kPa; Maximum tire pressure: Should not exceed 350 kPa. Here are the details: 1. Meaning of tire pressure: Tire pressure refers to the air pressure inside the tire. Tire pressure is the blood pressure of a car, and the level of tire pressure plays a crucial role in the car's performance and power. 2. Impact of tire pressure: Tire pressure is an important factor affecting the service life and economy of tires. Improper selection of tire pressure can cause power cycling, which increases tire wear and affects service life. Considering the impact on power performance, it is necessary to choose the appropriate tire pressure to extend tire life and improve economy.
I've been driving for decades, and normal tire pressure is generally between 32 to 35 psi, depending on your car. My old car used to run best at 32 psi. In summer, I'd lower it to 30 psi to avoid overheating and blowouts, while in winter, I'd inflate it to 35 psi for better traction. Remember, too low pressure is dangerous—it increases braking distance and the risk of a blowout, and you'll feel the steering wheel light and unresponsive. Too high pressure saves a bit on fuel but wears tires faster and makes the car shake more noticeably. I check it monthly with a manual pressure gauge—measuring an hour after the car has been parked gives the most accurate reading. New drivers, don’t overlook this. Safe driving starts with your tires, or you’ll pay the price in an emergency. During regular maintenance, have the mechanic check it—a small cost to prevent big trouble.
