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.
The only that I know of is that you need an alignment.
Yes, wheel alignment machines do need to be calibrated.
If you find out, let me know. I have the same question.
Steering wheel shakes
Have the car checked at a wheel alignment shop.
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.
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.
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.
You may need a wheel alignment, or you may need bushings.
No, you do not need new tires to get a wheel alignment. Wheel alignment can be performed on existing tires, regardless of their condition, as long as they are not excessively worn or damaged. However, if your tires are significantly worn, it might be a good idea to replace them before or shortly after an alignment to ensure optimal performance and safety.
