I am a mechanic and Alignment has nothing to do with vibration when you rotated the tires the bad tire was placed in the front now you feel the vibration more. Go get your tires balenced if it is a bad tire then you will know because it will not be able to be balenced
Did you have them balanced as well? If not, that's your problem. If you did have them balance your tires either have uneven wear, a slipped belt, or some other imperfection.
You probably need to get an alignment ($75). Your tires could be toed in or out and that's why it would feel like it's shaking when you go faster.
Have the wheels balanced.
You just moved an unbalanced tire/pair to the front where they are much more noticable.
They balanced them. Do u think it bad tires?
I rotated tires an now it's worse. Brakes r New.
