What is the recommended tire pressure for sedans in summer?

[VanMatthew]

In summer, the appropriate tire pressure for cars is generally between 2.2-2.4 kilopascals. Precautions for summer car tire maintenance are as follows: 1. Conduct frequent inspections. Even if time is limited, you should quickly check the vehicle's tires to see if there are stones or foreign objects in the tire grooves, and inspect whether the tire sidewalls have scratches or punctures exposing the cords. 2. Check tire pressure to ensure it is within the standard range, neither too high nor too low. 3. For vehicles frequently driven long distances at high speeds, it is necessary to regularly rotate the tires.
