How do you put tire pressure differently depending on the season?

pu1. I also thought that the air expands and lowers tire pressure because the weather gets hot in summer...
They say that you don't have to touch it because the proper air pressure is already adjusted by the experiment
In summer, adding 5% more air reduces the tire surface and produces less heat

OK

pu2. During the rainy season, it is recommended to keep the tire pressure 10-15% higher than usual to form enough tire grooves to drain rainwater

OK

pu3. The air expands in summer, so you can reduce it by 10% compared to winter
