its recommended but not required, I as a good practice because I figure if you just spent money on new tire you don't want them to wear faster than they should.
Wheels need alignment.
they are not always required but if the old tires had an odd wear pattern it would be in your best interest to have an alignment
No you do not. Bigger tires and wheels have nothing to do with it stopping.
Not 'required' , but certainly a good idea.
Tires out of balance, wheel bent, or both. Have the tires rotated and balanced, wheels inspected, and the front end alignment checked.
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.
There is no need to have a cars wheels aligned on a regular bases. It is a good idea though to have the alignment checked when installing new tires to prevent excess wear on the tires.
Not likely but it will wear the tires out.
Yes you can put bigger tires on your existing wheels up to a point. Talk to your local tire dealer and they can advise you on the biggest tires you can use.
new tires does not mean you don't need alignment. it is always a good idea to have the vehicle aligned after new tires are purchased to avoid premature wear, even if the car shows no sign of mis-alignment.
The CV joint provides power to the wheels. It has nothing to do with alignment.
It refers to the alignment of the wheels on a car. If you were to face the front bumper of a car, and you could grab the front tires at about the mid-way from the ground to the top of the tire, and then pull the wheels together towards the center of the car, then you would have cause a toe-in alignment of the front wheels.
