How to Check Tire Pressure in a Car?

[SanMaria]

If the vehicle is equipped with a built-in tire pressure monitoring function, the tire pressure can be viewed on the car's dashboard. If the vehicle does not have a built-in tire pressure monitoring function, there will be a tire pressure warning. The user manual, the driver's door (near the car's B-pillar), and the fuel tank cover also display the standard tire pressure. Different brands and models may have varying tire pressure requirements. Tire Pressure Monitoring: Tire pressure monitoring involves real-time automatic monitoring of tire pressure while driving, alerting the driver in case of tire leaks or low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure 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 automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in faster rotation compared to the other wheels. By comparing the rotational speed differences between tires, the system monitors tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): This system combines the advantages of both direct and indirect monitoring. It is equipped with direct sensors in two diagonally opposite tires and a four-wheel indirect system. Compared to a full direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like a direct system.

I often check tire pressure myself—super easy and saves money. First, get a tire pressure gauge, available at most gas stations or online for just over ten bucks. When using it, don't rush; turn off the engine and wait for the tires to cool down before measuring, as heat affects accuracy. Unscrew the valve cap, press the gauge onto the valve stem, and wait a few seconds for the reading—recommended values are on the door frame label or in the manual, usually 2.3-2.5 bar. If it's low, use an air pump to add air; if too high, release some. I check monthly—winter temps drop pressure easily, while summer does the opposite. Proper adjustment can save 10% on fuel and prevent blowouts. Uneven tires wear out fast, so checking early puts safety first.

As someone who frequently drives long distances, I prioritize accurate tire pressure measurement. I recommend first using the vehicle's built-in Tire Pressure Monitoring System (TPMS) - check whenever the dashboard warning light illuminates. The manual method is more reliable: choose a digital tire pressure gauge and test each wheel independently. Ensure the car is parked on level ground, take multiple readings to account for fluctuations, and use the average value. Refer to the manual for standard pressure values, and add 0.2-0.3 bar appropriately under different load conditions. I make it a habit to check every three weeks, especially before rainy days - proper tire pressure ensures better handling and reduces skidding risks. Consistent maintenance brings peace of mind and can extend tire lifespan by 20,000-30,000 kilometers.

I believe tire pressure check is a fundamental skill for safe driving. Low tire pressure increases friction, generates excessive heat, and raises the risk of blowouts; while overinflation leads to poor comfort and bumpy rides. I use a simple tire pressure gauge to measure every two weeks: unscrew the cap, press to read the value, and compare it with the label (usually on the door frame). If any abnormality is found, adjust it immediately. Maintaining proper tire pressure ensures stable handling, precise braking, and fewer accidents. Remember to check regularly—don't wait until the warning light comes on.
