Theoretically no, however using larger wheels adds weight which in turn decrease top speeds. Also, the use of larger wheels increases the amount of output an engine must make to make them turn, thus decreasing output. The other side is that a larger wheel increases the vehicle's footprint which in turn handles traction and torque much better. Thus, a happy medium would be optimal.
To help protect the vehicle and other vehicles behind you from flying mud and small stones.
In the case of a small bend you may be able to get it straightened but it is doubtful. The best thing to do is scrap the wheel and buy a new one. If it is caused by a kerb or other impact get the vehicle checked for alignment too.
Larger wheels have a larger diameter. Therefor, they will cover a greater distance per rotation of the driven axle, compared to a smaller wheel.
A very small amount of heat, as compared to an automobile's wheel. Entirely steel wheels have much less rolling resistance than a wheels with big squishy rubber tires.
A road vehicle, typically with four wheels, powered by an internal combustion engine and able to carry a small number of people.
Being that it is a push mower, the advantage is not having to lower the handle so far to raise the front wheels when making a sharp turn-around.
big wheels because they are good for handling
Small wheels have little rolling friction and helps to move faster in Skates
That is a given.
It can have anywhere from four (a small pickup with a dump body) to 22 or more (tractor and end dump trailer with lifting tag axles). For a straight truck in the US, the most wheels you'll get on a vehicle is a configuration which is known as a 'centipede' - it's a straight dump truck (10 wheels) with four lifting tag axles (8 more wheels), for a total of 18 wheels.
Big wheels of course. They will protect you better from falls over potholes
A motorcycle is a small motor vehicle with two wheels usually designed for one rider which is usually ridden for recreation but may also be used for commuting to and from work.
