No. It depends on the purpose of a tyre e.g. one designed for use for high performance will have smaller void ratios to ensure more rubber is in contact with the road. Related link:http://en.wikipedia.org/wiki/Tires#Tread
The same materials summer tires are made of. They just have a different tread pattern.
Aircraft tires are the same materials that auto tires are, just with a different tread pattern.
Yes - as long as the tyres on the same axle have the same tread pattern.
While it is good to use tires with the same tread and sizes, it is possible to use tires with different tread patterns, though you should be careful as the performance of the two tires may be different, causing your car to be unbalanced, endangering your passengers.

More than narrow tread tires.
Yes they can in regard to size, tread pattern and inflation pressure.
The best tires for a gravel road bicycle are typically wider tires with a tread pattern that provides good traction on loose surfaces. Look for tires with a width of around 35-40mm and a tread pattern that has knobs or grooves for grip on gravel. Brands like WTB, Panaracer, and Schwalbe are popular choices for gravel bike tires.
Tires have molded indicators called "wear bars." If these are visible across the tread pattern, your tires need to be replaced.
Both Winter and Snow tires have a more aggressive tread pattern and are made of a softer rubber that grips better in cold weather. I believe that snow tires have a still more aggressive tread pattern than winter tires.
Only if all tires have the same amount of tread left.
