Because air is highly-compressible.
When it is needed.The tire inflates when air is pumped in
No, there is a limit. The bicycle tyre should be inflated to the manufactures specified pressure for the tyre to perform properly and the bicycle to be safe to ride. Over inflating the tyre may cause it to pop off the wheel rim and burst.
i am a mechanic at bmw. if you are refering to runflat warning systems the idea is that the wheel speed sensors, which also are integral for your ABS system, can detect change in tyre speed. The reason that the wheel speed information can be taken as tyre pressure is because a fully pumped up tyre has a larger circumference that a flat one, therefore a pumped up tyre rotates slower than a flat. The wheel speed sensors send info on all tyre speeds to the cars computer system which compares them. when they are out of a specified tollerence then the flat tyre warning light will be turned on. This only works for sudden or consistent loss of pressure and the warning usually isnt activated for slow pressure loss, which is normal across all tyres.
it depends if your tyre is fully pumped or halfe pumped and weather it is a thin tyre or a fat on a thin tyre wouldn't -less surface area a fat tyre would-more surface area is on the ground so really it depends
carbon dioxide from the sprite inflates the gummybear :D
Air is pumped into car tyres to cushion the wheel from the road surface. Initially, car tyres were solid rubber and relied on leaf springs to soften the jolting from the road. The first practical pneumatic tyre was made in 1888, in Belfast, by the Scot, John Boyd Dunlop.
Yes. Riding on flat tyres run the risk of damaging both rim and tyre, the bike will roll poorly, and the tyre may even come off the rim, making the rim skid and slide all over the place - not a good thing.
it inflates it
There is a small explosive that inflates the airbag. It is not gun powder but its a good way to think of it.

Tyre Wear indicators are present on the tyre sidewall. They help in knowing the tread depth of the tyre. They indicate the degree of tyre wear. If the tread depth is less than 1.6mm, then the tyres become unsafe to drive.
