What is the normal tire pressure for the front wheels of a car?

The normal tire pressure for the front wheels of a car is 2.3 bar. There are two methods for tire pressure monitoring: direct tire pressure monitoring and indirect tire pressure monitoring. Direct tire pressure monitoring uses pressure sensors installed in each tire to directly measure the tire pressure, and then transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, displaying the tire pressure data for each tire. The working principle of indirect tire pressure monitoring is: 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. Indirect tire pressure warning systems essentially rely on calculating the rolling radius of the tire to monitor the pressure.
I often drive and have noticed that the normal tire pressure for the front wheels of a car is usually between 32 to 35 psi, but this isn't a fixed value—it depends on your car model and the recommendations in the manual. I make it a habit to check the tire pressure every time I stop at a gas station because low tire pressure can lead to increased fuel consumption, faster tire wear, and even difficulty in steering. One summer, my tire pressure dropped by 5 psi, and I nearly lost control on the highway—fortunately, I pulled over in time to address it. Winter is even more critical, as cold temperatures naturally reduce tire pressure, so regular adjustments are necessary. It's best to check with a simple tire pressure gauge at least once a month, and the most accurate readings are taken when the tires are cold. Don't guess the numbers—refer to the label on the driver's side door or the owner's manual to ensure safe driving. This habit has saved me a lot on repair costs and fuel expenses.
