What is the appropriate tire pressure for high-speed driving?
2 Answers
Generally, the tire pressure of a car should be maintained at around 220-260Kpa. Before driving on the highway, it is advisable to inflate the tires to around 250 or 260Kpa. If the tire pressure is too low, it can easily cause excessive compression and deformation of the tire cord layer during high-speed driving. As the speed increases, it may even lead to the phenomenon of standing waves in the tire, and in severe cases, it could result in a tire blowout. Here is more information about tire pressure: 1. Tire pressure refers to the air pressure inside the tire. The level of tire pressure has a crucial impact on the performance and power of the car. 2. Before driving, it is essential to check the condition of the vehicle, especially the tires. If the tire condition is poor, even the best car performance will be in vain. If the tire pressure is too low, the tire may be squeezed and deformed during driving, causing a rapid rise in tire temperature, which increases the risk of a blowout.
Tire pressure is crucial when driving at high speeds. I strongly recommend referring to the label on the door pillar or the recommended values in the vehicle manual, typically with cold tire pressure in the range of 30-35 PSI being suitable. Insufficient pressure can lead to unstable handling, overheating of tires, or even blowouts; excessive pressure reduces traction and affects safety. At high speeds, tire temperature can increase by about 10%, so setting the cold tire pressure at the lower end or slightly higher (e.g., 31-33 PSI) of this range can better accommodate changes. Remember to check the cold tire pressure with a tire gauge before each trip and regularly inspect tire wear and pressure balance. These habits not only enhance driving safety but also prevent unexpected failures, making your journey smoother and more enjoyable.
