Tires: New Tires, front end alignment, bad tire

Question
I recently had new tires put on my truck (week ago)...now I have a severe vibration when traveling between 65-75mph.
Is this bad tire balancing when they
we put on or is this a front end alignment issue
since it now slightly pulls to the left..appreciate your time....thanks....

Answer
Robert,

Both the pull and the vibration might be related to the new tires.

Aside from balancing - which could be the source of the vibration - the tires could be out of round.

The pull might also be caused by the tires and the way to tell is to swap the 2 front tires - side to side.  If the pull reverses diecrtion, it's the tires.  If the pull doesn't change is alignment.  If the pull goes away, it's both the tires and the algnment.
