Scalar
Air pressure in a tire is a scalar quantity because it has magnitude but no specific direction associated with it.
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.
The pressure inside a tire increases at the end of a journey due to a combination of factors such as heat generated during motion causing the air in the tire to expand, and the tire's construction materials allowing for some flex under load which can increase pressure. Additionally, as the tire heats up, the air molecules move faster and spread out, leading to an increase in pressure inside the tire.
The term for the difference between the pressures inside and outside a tire is called "tire pressure differential."
The difference between the pressures inside and outside a bicycle tire is called tire pressure differential.

scalar
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.
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.
The air pressure inside a tire is typically measured in pounds per square inch (psi) or kilopascals (kPa). This measurement helps ensure that the tire is properly inflated for optimal vehicle performance and safety.
NO - there isn't a pressure sensor inside the spare
When a car tire is inflated, the air particles inside the tire collide with the walls of the tire and with each other, creating a force that exerts pressure on the walls of the tire. The pressure builds up as more air is pumped into the tire until it reaches a point where it is equal to the atmospheric pressure pushing back on the tire.
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.

inside drivers door there is a label that states correct tire pressure.
they hit the walls/side of the tyre and that builds pressure
