Answer the steering wheel will pull to one side or the other when you are driving.

Best way to know is to look at the tread wear pattern on the tires. or simple go to a garage and get the alignment checked out.
It is in the way you wheel wear. If you go to tyre centre they will be able to tell you if you need an alignment as they can see the way you tyres are wearing.
Yes, wheel alignment machines do need to be calibrated.
The only that I know of is that you need an alignment.
If you find out, let me know. I have the same question.
Steering wheel shakes
No. If there had previously not been any alignment issues, and as long as the new tires are properly balanced, you will not need an alignment.
Have the car checked at a wheel alignment shop.
if you have independent suspention front and rear chances are a 4 wheel alignment can be done typically front wheel drive vehicles but not all.
A two wheel can be done, but a four wheel is preferred.
You may need a wheel alignment, or you may need bushings.
Check your tires. The tread should wear evenly. The steering wheel should not "pull to one side or the other." If either of these is not correct then an alignment is needed.
NO That depends on how the struts attach to the knuckle or control arm. On some front wheel drives an alignment is required.
