Which part of the tire will experience increased wear if the tire pressure is too high?
2 Answers
Tire pressure that is too high will cause increased wear on the central part of the tire tread. Tire pressure will rise or fall with changes in temperature and tire temperature. Generally, for passenger cars and SUVs, the recommended tire pressure when the tires are cold is around 2.3-2.5 bar. Factors affecting tire lifespan: 1. Low tire pressure: Both excessively low or high tire pressure will affect the tire's lifespan. If the tire pressure is too low, the radial deformation increases, causing excessive deformation on both sides of the tire wall, leading to wear on the shoulders of the tread. This also raises the tire temperature, significantly reducing the tire's lifespan. 2. High tire pressure: If the tire pressure is too high, the tire's rigidity increases, deformation and contact area decrease, resulting in higher unit pressure on the central part of the tread and accelerated wear. This causes central tread wear, affecting comfort and reducing tire lifespan.
In my driving experience, the most affected part when tire pressure is too high is the center of the tread. Excessive pressure causes the tire to bulge, making only the middle section tightly contact the road surface. Over time, that area wears out particularly fast. I remember one time when the tire pressure was too high, the center of the tire flattened quickly, causing the car to feel a bit floaty and lose grip on the highway. Fortunately, I checked in time. I recommend using a simple tire pressure gauge every month to ensure it doesn’t exceed the value marked on the door frame. Also, regularly check the tire tread—if the center is significantly thinner than the rest, it’s time for a replacement. Ignoring this issue not only wastes tires but also increases the risk of blowouts and accidents. Driving safety is the top priority.
