Best Answer

The air molecules bouncing around off the inside of the tire. If you force something into a confined space that is usually allowed to be free it will exert pressure(Force) on th walls of it's container. An increase in tire temperature or friction will cause the air pressure to increase while colder temperatures will cause it to decrease.
