Not 100% sure, but if they were different style or brand, I'd say they had to be.
It is always a good idea, however if the old tires wore evenly, the car didn't drift or pull with the new tires, then you could pass on the alignment and keep an eye on the way the wear. Rotate every 5-8000 miles.
As a service center manager, I always suggest an alignment with the purchase of new tires for several reasons. 1. When your vehicle is in alignment you are preventing premature tire wear. This translates to $$ saved in the long run by not having to buy tires as frequently. 2. All vehicles' suspensions wear over a period of time, by having your alignment checked periodically you can prevent a worn part from becoming a broken or failed part. This is a simple safety issue in this regard. (The alignment technician should thoroughly check the suspension BEFORE doing an alignment to spot any conditions/parts that should be addressed.) 3. By keeping your car aligned you can increase your gas mileage and tire life. Last but not least, your mechanic/garage should provide you with a printout showing your alignment specs before AND after any adjustments have been made. Ask your salesperson/technician/manager to explain the printout and how it will affect your vehicle. Most shops will offer not to charge you if no adjustments were needed.
ANSWER: NO! although it is recommended, putting new tires on your vehicle doesn't change the alignment, it will still be out of alignment, or in alignment when you put your new tires on.
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.
I'd at least have it checked, just to be sure everything's fine
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.
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.
You sould have the new tires mounted FIRST, then have them do the alignment at the same visit.
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.
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.
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.
You could, but it would be more accurate with new tires.
Wheels need alignment.
