What Causes Abnormal Tire Pressure?

The causes of abnormal tire pressure include: 1. Abnormal tire pressure caused by a puncture; 2. Excessive or insufficient tire pressure in a particular tire. Tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a crucial role in the performance and power of the vehicle. Below are the hazards of abnormal tire pressure: 1. Increased fuel consumption: The friction coefficient with the road surface increases, leading to higher fuel consumption; 2. Safety issues: Results in heavy steering and a tendency to veer, creating unsafe driving conditions; 3. Abnormal heat generation: Increases the movement of various parts of the tire, causing excessive rolling and abnormal heat generation; 4. Risk of blowout: The friction between the tire and the ground multiplies, increasing the risk of a blowout.

I've been driving for many years and have encountered tire pressure issues several times. The most common problems are nails or glass shards puncturing the tires, causing slow leaks that take days to notice. Temperature fluctuations have a particularly significant impact - tire pressure drops sharply during winter cold snaps and surges when driving on highways in summer. Deformed wheel rims can also cause chronic air leaks, especially in older vehicles or those frequently driven on rough roads. Cracks from tire aging are another hidden danger, particularly in tires over five years old. Poor valve core seals are vulnerable too, often damaged by high-pressure car wash hoses. Keeping a portable tire pressure gauge in the car is very practical, and checking monthly is the safest approach.

As the primary driver in the family, I pay close attention to tire pressure safety. Punctures from sharp objects are the most common issue; sometimes just driving past a construction site can cause it. Overloading can also easily flatten tires, especially noticeable when the car is fully loaded with luggage for family trips. Tire pressure must be adjusted during seasonal changes between winter and summer. Last winter, I neglected this, and all four tires lost pressure. Long-term parking is the most troublesome; tires can lose up to 30% pressure after three months of inactivity. Repaired tires are more prone to leaks; my car has a patched tire that always loses pressure. Faulty tire pressure monitors can also give false readings; last time at the 4S shop, it turned out to be a sensor issue.

Just dealt with a tire pressure warning last week, what a profound lesson. Punctures are the most common issue - my car's been nailed by screws twice. Severe jolts can deform rims; after hitting a deep pothole last time, my tire slowly lost air. High-speed driving in extreme heat is particularly dangerous - pressure can exceed 3.0 bar. Aging tires become problematic too, as hardened rubber develops cracks and leaks. Missing valve stem caps allow dust ingress, compromising sealing. Improper repairs cause secondary leaks - that shoddy patch job from a roadside shop failed again. Make monthly checks a habit.
