What are the reasons for low tire pressure in the Volvo XC40?

Volvo XC40 low tire pressure reasons are: 1. Car tire damage leading to air leakage; 2. Natural aging of tires or prolonged vehicle parking causing slow air loss. Tires are one of the important components of a car, directly contacting the road surface and working with the car suspension to cushion the impact during driving. Taking the 2021 Volvo XC40 as an example, its body structure is a 5-door 5-seat SUV, with body dimensions of: length 4425mm, width 1863mm, height 1652mm, wheelbase of 2702mm, and a trunk capacity of 460l.
As a long-time XC40 owner, I was also constantly annoyed by the tire pressure warning last winter. There are many reasons, the most common being slow leaks like nails. I remember once finding a small nail hidden in the tread during a tire repair—it took three or four days to leak enough to trigger the alarm. Temperature drops also cause significant thermal contraction; last week, my tire pressure dropped by 0.3 bar due to the cold. Aging wheel rims are another hidden risk—the car wash owner said coastal areas are prone to oxidation and leaks. Oh, and one time the warning was a false alarm! A system reboot fixed it. Now, I’ve made it a habit to keep an air pump in the trunk. When the alarm goes off, I manually check the pressure first—it’s the most reliable method, since increased tire noise or pulling while driving can already be quite dangerous.
