they hit the walls/side of the tyre and that builds pressure
Tyre pressure is caused by the air particles inside the tyre
yes it can cause low tire pressure
Because the particles all inside are moving causing lots of pressure which also causes it to burst and then the particles are relieved.
Because the air inside the tire is under pressure. Gas always flows from a region of higher pressure to a region of lower pressure. As the pressure inside the tire is greater than the pressure outside, the air always comes out of the bicycle tyre.
If inside and outside same pressure that means there is no pressure. The added pressure is what blows the tire up like a balloon and holds the weight of the car up.
As a tire goes round and round heat builds up inside the heat expands the air inside the tire. On a normal day that he can dissipate but as the temperature on the outside increases is more difficult for the heat (energy) to leave the inside of the tire. As the temperature increases the pressure inside the tire also increases. It is that pressure that can cause the tire to explode.
Air leaves a tire when the tire valve is open due to the pressure. The pressure outside of the tire is lower than the pressure inside the tire.
NO - there isn't a pressure sensor inside the spare
The tire will have a recommended psi printed on the tire, it is best to follow this recommendation. Check inside driver door for tire pressure information. Tire lists max pressure at max load. Mfg will set tire presure on sticker inside driver door.
scalar
The air particles are closer together creating more pressure inside a ballon or tired and makes it expand
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.
