because the friction heats the air, and it tries to expand.

Because of all the work the tires do, the air inside heats up. The same amount of air in the same space at a higher temperature means increased pressure. The formula would bore you to tears.

The tires get hot from the friction against the road. So the air inside the tires gets hot, too. Air wants to expand when it gets hot.

the air inside expands with the rise in temperature, the tires get hot, therefore the air inside is heated as well, thus the pressure is increased.

PV= nRT
As the car moves, the tires heat up and so does the air inside them. Since the air heats up, it expands, then the pressure goes up.

Friction between the tires and the highway creates heat, which makes the air in the tires expand.

the tires get hotter from road friction, hot air tries to expand so they register more pressure. This is why all tire pressures are supposed to be measured cold.

Friction=heat=molecules moving faster and faster=increase pressure.

because your tire picks up air molecules as it rolls over them

Heat, expansion.
