One of the signs of tire wear is when you see the tread disappearing and falling off. If you check your tires you may notice that one or more has very little tread left. Different signs of tire wear also include seeing the steel belt coming through the rubber, and your ride feeling a bit rougher.
When the tire tread wears down to the wear bars, the tires are ready for replacement.

Camber and toe can both cause inner tire wear.
Yes, if camber is not right the tire will wear prematurely.
Extreme braking and low inflation cause wear on a bike tire.
Yes. Low pressure will cause edge wear. Over inflation will cause center wear.
A tire alignment is not necessary when changing tire sizes. You can tell by the wear on your previous tires if you need an alignment. If you have uneven wear, get an alignment.
The most common cause of uneven tire wear is a wheel alignment problem. The fix could be as simple as getting the car realigned or it may involve replacing steering/suspension components prior to performing an alignment. Tire pressure is also a common cause of tire wear. If the air pressure is too high inside the tire then the tire tread will wear more in the center. If the air pressure is too low the tread will wear more on the outside edges. Aggressive breaking/acceleration can also be a cause of tire wear problems.
