Not necessarily. If the car was in alignment prior to getting the new tires, it will be in alignment after the new tires. It isn't a bad idea to check the alignment periodically and it is probably better to check it more frequently than when you get new tires.
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.
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
Good idea to do at the same time
No, not as long as normal wear pattern on the old ones.
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.
Depends on when you had your last alignment and the condition of the tires you removed. It they were wearing perfectly even then you may not need an alignment. If you have not had an alignment in the last 36,000 miles you may very well need one. Judgment call on your part based on the evidence.
You sould have the new tires mounted FIRST, then have them do the alignment at the same visit.
No, the wheel and tires should both be straight at the same time.
The tires have nothing to do with alignment. The car could be aligned with the scalloped tires. They are scalloped from bad alignment, shocks, struts or damaged to the front end. An alignment in itself may not fix the problem. There may need to be some new parts installed before the alignment. You only need to replace the two scalloped tires. A four wheel alignment can be done with new ones on the front and old ones on the back. Rotating them at some point will not affect the alignment.
If you bought new tires I would suggest you get an alignment also, this way you are ensuring the life of the tire. Plus some tire shops will not warranty the life of the tire if you have a bad alignment
go get 2 new tires and have the alignment checked on it
No.
