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.
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.
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.
Yes, it's recommended to get a wheel alignment when you install new front tires. This ensures that the new tires wear evenly and helps maintain proper handling and steering. Misalignment can lead to uneven tire wear and negatively affect vehicle performance, so it's best to get it checked after replacing tires.
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.
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, you do not have to purchase new tires before getting a wheel alignment. An alignment can be performed on your existing tires as long as they are in good condition and have sufficient tread. However, if your tires are worn out or damaged, it may be advisable to replace them first to ensure optimal performance and safety.
I'd at least have it checked, just to be sure everything's fine
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
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.
Your driveline may need alignment (front end alignment), you may have warped rotors, or you could have bad "ball joints".
