What causes the Volvo XC60 to display low tire pressure?

[VanParker]

Volvo XC60 displays low tire pressure for the following reasons: Damaged car tire: When a car tire is damaged, it will inevitably leak air, and over time, the tire pressure will drop. If a car tire is damaged, it must be repaired or replaced promptly to prevent safety hazards. There are many methods for repairing tires, including hot patching, mushroom nail method, and rubber patch method. If the tire is severely worn, it is best to replace it with a new one directly. After replacing the new tire, a four-wheel alignment should be performed promptly to prevent the vehicle from pulling to one side. Slow tire air leakage: There are many reasons for slow tire air leakage, including natural aging of the tire and the vehicle being parked for too long. When parking the car for an extended period, it should be placed on a flat and hard surface to prevent the tires from being deformed due to prolonged pressure. Additionally, if the car is not driven for a long time, it should be started at least once a week to ensure the fluids in the engine and the battery can function properly.

I've been driving a Volvo XC60 for over three years and have encountered the tire pressure warning several times. The most common issue is punctures, like when a small screw gets stuck in the wheel rim, causing the tire pressure to slowly drop. In winter, temperature drops can also trigger the alarm due to thermal expansion and contraction. Last time the temperature dropped, all four tires lost about 0.2 bar. Natural air leakage is also unavoidable, especially after four or five years when the rubber ages and the valve core seal deteriorates. Once, I even experienced a false alarm due to interference with the tire pressure sensor signal near a high-voltage power tower, which resolved after restarting the system. The car's tire pressure monitoring is quite sensitive, so it's advisable to check with the onboard air pump immediately when a warning appears. If the pressure is significantly low, it's best to get the tire repaired.

Having dealt with numerous tire pressure issues on the XC60, I've summarized the five main causes: nails stuck in tires are the most common, especially when the sidewall is punctured; secondly, temperature fluctuations can trigger warnings, like a sudden 5-degree drop when driving into mountains in summer; neglected valve stems may age and leak; wheel rim deformation leading to poor sealing requires attention; although rare, TPMS sensor failures can occur, with depleted batteries potentially causing errors. Volvo uses direct TPMS, so it's advisable to carry a mechanical tire pressure gauge for verification—visit a service center if the discrepancy exceeds 0.3 bar.

Tire pressure is really something to take seriously. My XC60 triggered an alarm on the highway last year. Most cases involve punctures from nails, but the most dangerous was when a steel bar at a construction site slashed the tire sidewall. Seasonal temperature changes have a particularly noticeable effect. Another easily overlooked issue is failing to reset the sensor data after changing tires. Now I've developed a habit: every month, I use the built-in air pump to check the cold tire pressure, keeping it around 2.5 bar. If the alarm goes off, don't panic—pull over to the emergency lane, confirm the tire isn't flat, then drive slowly to a repair shop.
