Yes, it does in a big way.
No. Improper pressure will.
low tires cause drag and it takes more to push these tires down the road. most bikes run about 40psi.
No. Suspension damage, probably, tire damage, probably, but no they don't lose air. If you are losing air you probably have a slow puncture, or worse damaged wheels, or possible damaged beading. The only time a speed bump would cause air loss is on aready incorrectly inflated tires.
It is what fills the tires, in the form of air.
There are no 'types' of air. Air is all just air. - Some people do use nitrogen in tires - that is not air.
In standard cars is it simply compressed air. The same mixture we breathe.
Air shrinks when it's cold. Your car tires lose pressure, but have enough volume that the tires don't go flat.Bike tires don't have the storage volume, so they go flat.Or, you could just have a slow leak.Because the oxygen molecules in the tire arent moving as fast as they would be in the heat. The heat causes friction between atoms.
LOW AIR PRESSURE IN YOUR TIRES loose accessory belts such as alternator can squeal
If air is escaping from your tires then you have a leak. Repair the leak and no more air will escape. This is not to say you never have to check the air pressure. Tires are made from a porous material and as such will loose a very small amount of air even under the best of circumstances. Check the pressure on a regular basis.
Air expands when heated so therefor increases the preasure
Well if the tire is completely filled to its max air pressure. The sun could weaken the rubber and then cause the air to expand int he tire because its in the heat. That may be the cause of an exploding tire in the sun
