Well, the answer is maybe - it depends on the type of tire you are using. Some tires are either asymmetrical or unidirectional. Asymmetrical tires have a tread pattern such that the tire has a distinct "outside" and "inside" - that is, the tire must be mounted such that the outside part of the tread faces the outside of the wheel. These tires can rotate in either direction. Unidirectional tires have a tread pattern that requires the tire to rotate in one direction only. This type of pattern may help direct water better and can be seen on many wet-weather specific tires.
Note the unidirectional tire has a tread pattern that will funnel water away when rotating in one direction and suck water in when rotating in the "wrong" direction.
So you can "rotate" or swap your fronts and rears on a staggered fitment if you are using universal or asymmetrical treat patterns, but not if you are using unidirectional tread patterns. Just swapping the front wheels left to right might help a little - especially if your car has different alignment specs for the left and right, but it's unlikely to be of significant benefit compared to being able to rotate all four wheels.
it means the wheels sizes are different. Front wheels may be 8.5 inches in width, the rears might be 9 or 10.5. Bascially you cannot rotate the fronts with the rear wheels/tires
Unless a brake is engaged, the wheels on a car in neutral can rotate backwards. If the car is in gear, wheels attached to the power train probably will only rotate backwards if the car is in reverse gear. If it is in forward gear or "park" they should not rotate backwards. Wheels not connected to the power train should be able to rotate either direction.
They rotate and can be braked, just like auto wheels. Nose wheels can be steered.
Cars have circular wheels to move the easiest. Because of the circle's shape, the wheels can rotate easily. If they were not circles, it would take a great amount of work and energy to get the wheel to rotate.
Yes but to do it correctly you should put the wider wheels on the front to eliminate understeer and to get the car to rotate more in corners. In the tuning world however you will see people running wider REAR wheels for the look, especially the VW crowd. While there isn't any real danger to this, running wider rears on a fwd car will cause excessive under steer and is generally kind of pointless.
Usually the back wheels are the ones connected to the engine, providing the power to rotate the tracks, and these are the drive wheels. The rest are bogey wheels.
Fronts are 18's and rears are 19's
While turning, the inside wheels take a shorter path than the outer wheels so they must rotate at different speeds.
