What is the best tire pressure in summer?

In summer, a tire pressure of 230kPa is most suitable. Below is the relationship between tire pressure and vehicle performance: 1. Relationship between tire pressure and load capacity: Tire pressure is an indicator of a vehicle's load capacity. The size of the vehicle's load 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. 2. Relationship between tire pressure and vehicle power performance: 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. 3. 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 pneumatic tires has greatly improved the riding comfort of vehicles.
In summer driving, I find tire pressure is crucial. Normally, it's recommended to check the label on the door frame, usually around 32 to 35 psi. However, in high summer temperatures, the air inside the tires expands, leading to increased pressure which can cause overheating or even blowouts. I suggest setting it 1 to 3 psi below the standard value, like 30 or 31 psi, for more stability on the road. Remember to check monthly with a simple tire pressure gauge, especially before trips. If the pressure is too low, tires wear out faster and consume more fuel; if too high, grip decreases, increasing the risk of slipping in rain. Personally, I pay extra attention to this in summer to ensure safe and comfortable driving.
