What is the best tire pressure in summer?
2 Answers
In summer, a tire pressure of 230kPa is most suitable. Below is the relationship between tire pressure and vehicle performance: Relationship between tire pressure and load capacity: Tire pressure is an indicator of a vehicle's load capacity. The load capacity of a vehicle depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity. Relationship between tire pressure and vehicle power: When a vehicle is driving at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance. Tire pressure has a significant impact on the rolling resistance coefficient. Relationship between tire pressure and vehicle ride comfort: The ride comfort of a vehicle is directly related to the comfort of the driver and passengers. In fact, the use of inflatable tires has greatly improved the riding comfort of vehicles.
I've been driving for many years, and tire pressure is especially important in summer. When temperatures are high, air expands quickly, causing pressure to rise easily, which can lead to uneven tire wear or reduced grip. The recommended pressure is generally between 2.2 and 2.5 bar, depending on the label on the door frame or the vehicle manual. For example, my car's recommended pressure is 2.3 bar, but in summer I set it to 2.2 bar to account for expansion. However, don't set it too low, as the tire sidewalls can overheat and burst during high-speed driving. It's best to check the pressure with a gauge before a trip, and wait until the tires cool down for a more accurate reading. Correct tire pressure not only ensures safety and comfort but also saves fuel and extends tire life. I recommend checking it every two weeks, especially before long trips in hot weather. These small habits can prevent big problems.
