What is the recommended tire pressure for highway driving?
1 Answers
Generally, the tire pressure of a car should be maintained at around 220-260 kPa. Before driving on the highway, it is advisable to inflate the tires to approximately 250 or 260 kPa. Below are some relevant details: 1. Definition of tire pressure: Strictly speaking, tire pressure refers to the air pressure inside the tire. In car maintenance, the engine plays the role of the car's heart—if the engine is damaged, the car's lifespan will be exhausted. Similarly, tire pressure symbolizes the car's blood pressure, and its level has a crucial impact on the car's performance and power. Tire pressure is the lifeblood of the tire; both excessive and insufficient pressure will reduce the tire's lifespan. 2. Dangers of low tire pressure: If the tire pressure is too low, it can cause excessive deformation of the tire's cord layers during highway driving. As the speed increases, this may even lead to the phenomenon of standing waves in the tire, and in severe cases, it can cause a tire blowout (the fatality rate of high-speed blowouts is almost 100%). Therefore, to ensure driving safety on highways, it is essential to maintain adequate tire pressure. 3. Dangers of high tire pressure: If the tire pressure is too high, it can cause the tire cords to overstretch and deform, reducing the tire's elasticity and increasing the load during driving. This makes the tire more prone to internal cracks or bursts upon impact. Additionally, excessive tire pressure accelerates tread wear and reduces puncture resistance.
