What Causes Excessive Tire Pressure?
2 Answers
The reasons for excessive tire pressure include: over-inflation of the tire leading to high pressure; hot weather causing gas expansion and increased pressure; prolonged driving generating heat through friction, raising the pressure; and aging or worn suspension components related to the wheels, resulting in misalignment, uneven wear, higher temperature, and increased tire pressure. Hazards of excessive tire pressure: Reduced friction and adhesion of the tire, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern, shortening tire lifespan. Increased vehicle vibration, indirectly affecting the lifespan of other components; excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; decreased puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts due to impact, leading to a tire burst.
When I checked my car, I found the tire pressure was too high, which is often due to rushing during inflation, inaccurate readings from the pressure gauge, or simply overinflating. Sometimes, the tire pressure gauge itself has errors, or temperature changes cause gas expansion—tire pressure can rise quickly after driving in summer. Driving with overinflated tires feels bumpy and uncomfortable, handling worsens, and the center of the tire wears out faster, possibly requiring early replacement and increasing expenses. I remember once before a long trip, I adjusted the tire pressure slightly higher, only to end up with back pain from the rough ride. Later, a mechanic told me regular checks are key. Now, I’ve developed the habit of checking monthly with a digital tire pressure gauge, always measuring when the tires are cold, ensuring I follow the recommended values on the door frame. Never take it lightly—safety first.
