What are the effects of excessive tire pressure?
2 Answers
The effects of excessive tire pressure: 1. It will reduce the friction and adhesion of the tire, affecting braking performance and shortening the tire's lifespan; 2. It decreases the tire's resistance to punctures, increasing the risk of a blowout; 3. It accelerates localized wear on the central tread pattern, reducing tire life, increasing vehicle vibration, and indirectly affecting the lifespan of other components; 4. It causes excessive stretching deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car during driving. The recommended front tire pressure is 2.2 to 2.3 bar when unloaded and 2.4 to 2.5 bar when fully loaded; the rear tire pressure is 2.4 to 2.5 bar when unloaded and 2.6 to 2.8 bar when fully loaded.
When I used to drive long-haul trucks, having tire pressure that was too high caused a bunch of issues. The vehicle's handling was terrible, especially when taking curves—it felt like floating. On wet roads, the braking distance increased significantly, making it prone to skidding and accidents. I remember one rainy day when I almost ran off the road because the excessive pressure reduced tire grip. The center of the tires wore out incredibly fast, becoming bald after just tens of thousands of kilometers, forcing me to replace them prematurely and waste thousands of dollars. The ride comfort was also poor, with the vehicle bouncing so much that passengers complained about sore bottoms. On hot days during high-speed driving, overinflated tires increased the risk of blowouts due to excessive thermal expansion. I recommend checking the tire pressure with a gauge every day before setting off and maintaining the standard value listed on the door label to avoid these small issues turning into big problems.
