What are the reasons for low tire pressure in car tires?

Reasons for low tire pressure in car tires: 1. Slow air leakage in the tire; 2. The tire is punctured and leaks air; 3. False alarm from the tire pressure monitor. Tire pressure refers to the air pressure inside the tire, which is the blood pressure of the car. The level of tire pressure plays a crucial role in the car's performance and power. Low tire pressure poses a significant threat to driving safety and can easily lead to tire blowouts, especially in summer. Low tire pressure increases the friction between the tire tread and the ground, leading to higher rolling resistance, a sharp rise in tire temperature, softening of the tread rubber, accelerated tire aging, local delamination of the tire body, and increased tread wear, making tire blowouts more likely to occur.
I've found several main reasons for low tire pressure. The most common is natural air leakage, as gas gradually permeates through the rubber, especially noticeable in aged treads. Punctures are another frequent issue - driving over nails or glass can cause slow leaks. Temperature changes play a crucial role too; tire pressure drops with rapid winter temperature decreases and rises in summer. Additionally, damaged or loose valve stems can lead to air loss. The consequences of low tire pressure are significant: accelerated tire wear, increased fuel consumption, and even potential blowouts, particularly dangerous on highways. I recommend checking with a tire gauge at least every two weeks, and promptly inflating if pressure is low. A quick visual tire check before driving can also prevent small issues from becoming big problems.
