Your speed is based on how many times the axle rotates and is calculated by the car manufacturer based on the wheel size. If you used a tire that was bigger than standard such that the outer ring that touches the road was twice as long, your speedometer would read half the speed. So your mph speed of the car remains the same, but the speedometer registers it as half.
No. The pressure increases with temperature increase
Yes. The warmer a tire gets, the more air pressure increases. You should not notice a increase of more than 3-5 psi ( or a decrease if it is cold out ).
The air in the tire is becoming heated due to the tires friction on the road surface. Heated air increases the pressure in the tire
As you drive, the friction of the road and the flexing of the tire increases the tires temperature. When you increase the temperature of a gas in a sealed container the pressure goes up.As you drive, the friction of the road and the flexing of the tire increases the tires temperature.

No, it will decrease gas mileage.
Increase your following distance. It will take you longer to stop. Slowing down is also a really good idea.

The size of the wheel itself does not affect performance or fuel economy, but the height of the tire does. A taller tire will decrease performance, but increase fuel economy. A taller tire would have a larger circumference, and therefore decrease the engine speed (RPM's) leading to the improved economy. On the other hand, a taller tire also acts to reduce the car's ability to accelerate (like changing the gear ratio). Also, the speedometer won't be accurate any more.
you should always check your tire inflation pressure when your tires are cold, and inflate them to the recommended pressure at that time. A good estimate to use when comparing tire pressure to air temperature is for every 10 degrees F, tire pressure will adjust by 1 psi. For example, if the outside air temperature increases 10 degrees, the tire pressure will increase by 1 psi. Conversely, if the air temperature falls 10 degrees, the tire pressure will decrease by 1 psi.
No. The car tire will not reduce its chances of being hit by lightning. If anything the tire would add height, which could increase the chances of being hit, though this increase in chance would be negligible.
Within a central tire inflation system, a driver adjusts the settings governing an electronic control unit, which manipulates the tire valves to increase or decrease air pressure in order to improve tire performance on varying terrains.
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.
