When the vehicle is stationary, locate and press the 'mycar' button on the center console, select the tire pressure monitoring option, press the confirm button, and then drive for a while to allow automatic calibration. Hazards of Overinflated Tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread center pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass on the road can easily penetrate the tire, causing internal cracks and blowouts. Hazards of Underinflated Tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement in various parts of the tire, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, leading to bead damage and abnormal wear; Multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; Increases tire body deformation, leading to sidewall cracks and excessive heat from flexing, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.

Calibrating Volvo's tire pressure is actually quite simple, and I do it myself every season. First, make sure the car has been stationary for at least three hours to allow the tires to fully cool down. Then use a tire pressure gauge to check if the pressure in all four tires matches the standard values on the door frame sticker. In winter, you can set the pressure 0.1Bar higher than the standard. After starting the car, don't drive off immediately. Find the 'My Car' menu on the central display, select 'Tire Monitoring' in the 'Settings', and click 'Tire Pressure Calibration'—it will prompt for confirmation. Here's the key point: After confirmation, you must drive continuously for more than 20 minutes, ideally maintaining a speed between 40-80km/h, as the system needs this driving time to collect data. If you encounter a false alarm, don't panic—it's mostly caused by data drift due to bumpy roads, and you can simply recalibrate. Remember to check the spare tire pressure as well, as many people overlook this.

Inaccurate tire pressure directly affects driving safety and fuel consumption, so I always calibrate it before long trips. The specific steps are divided into three parts: measure and adjust the tire pressure to the standard value when the tires are cold and the car is parked—it's best to do this in the early morning during summer; access the TPMS reset option in the vehicle settings menu on the central console (the location varies slightly depending on the car model); finally, drive continuously for 25 minutes to let the system automatically learn. A handy tip: calibrating on a ring road is faster than on city streets, and maintaining a steady speed of 60 km/h works best. If you switch to snow tires or have a tire repaired, calibrate immediately. Remember, new tires may require readjustment after 500 km as the pressure changes. A mechanical tire pressure gauge is recommended over an electronic one for more reliable results.

My experience with Volvo tire pressure calibration highlights three key points. First, it must be done in a cold tire state – the vehicle should be turned off for at least three hours for accurate measurement. Second, the procedure varies by model: older models require accessing settings through the steering wheel menu, while newer models operate via the touchscreen. Third, driving calibration must be continuous – if you stop for more than five minutes, you'll need to start over. Don't forget to adjust the spare tire pressure simultaneously. For models with tire pressure memory function, simply press the key fob's lock button after calibration to save the data. If the tire pressure light keeps coming on, it's likely a slow leak – check the valve core and wheel rim edges.
