What Causes Low Tire Pressure in New Cars?

[AdrianFitz]

Low tire pressure in new cars may be due to leaks in the tire or valve stem, which require inspection at a tire shop; deformation of the wheel rim, leading to reduced sealing performance of the tire; thermal expansion and contraction, as manufacturing differences in tires may result in insufficient tire pressure due to temperature changes. Additional information is as follows: 1. Tire Pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car—its failure can lead to the end of the car's life—while tire pressure is akin to the car's blood pressure. The level of tire pressure plays a crucial role in the car's performance and power. 2. Hazards of Low Tire Pressure: Increased friction with the road surface, leading to higher fuel consumption; causes the steering wheel to become heavy and may lead to veering, both of which are detrimental to driving safety; increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction between the tire and the rim, resulting in damage to the bead area and abnormal wear.
