What are the causes of excessive tire pressure?

The causes of excessive tire pressure are: 1. Over-inflation of the tire; 2. Incorrect wheel alignment of a particular wheel, leading to uneven tire wear and elevated temperature. 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. Automotive tires are one of the key components of a vehicle, directly in contact with the road surface, working in conjunction with the vehicle's suspension to mitigate the impact experienced during driving, ensuring good ride comfort and smooth driving. They also ensure excellent adhesion between the wheels and the road surface, thereby improving the vehicle's traction, braking, and off-road capability.
As a white-collar worker who frequently commutes by car, I pay special attention to tire pressure issues. The most common cause of overinflation is adding too much air due to shaky hands during inflation. Many people rush through the task when busy, forgetting to carefully check the pressure gauge. Especially in summer, when tire temperatures rise, gas expansion leads to excessive pressure, making the ride feel bumpy and stiff, severely affecting comfort. Another scenario is inflating to the standard value in cold weather, only for the pressure to spike when the sun comes out and temperatures suddenly rise. More troublesome is the change in load—for example, inflating after loading a lot of cargo, only for the pressure to become too high once the vehicle is unloaded and empty. To prevent this, I’ve developed a habit of checking tire pressure when the temperature difference between morning and evening is minimal. I carry a digital tire pressure gauge with me and measure the pressure every two weeks. Overinflated tires accelerate wear in the center, shortening their lifespan, and increase the risk of blowouts at high speeds—something you’ll deeply regret if it happens. In short, regular checks are key; don’t skimp on those few minutes.
