Probably, yes.

Also wheels out of balance make shake. My "rebalanced" wheels were not balanced with any bit of care, and the car still shimmied.

Bent rim with make shake.

I agree with Sperry. I would rotate the tires front to rear first, and see if the shaking stops.

When a vacuum boosted mount breaks it causes what?? a vac leak and poor running!!
Broken mounts should be replaced now

I would replace the broken mount and fix the problem

Unless you recently hit a pothole to hurt a rim,,,look at the real problem- not what you can waste time by trying the tire swap
If you had said `right after I rotated there is a shimmy,
and btw I have a broken front motor mount`...I would suspect rim problem then mount

rim balance issue would not show up at 30-45 mph as OP stated
It would be all the time- you will know if it happens to you!

ok then- lets say a minor rim issue wont show up till the higher speeds
I had some that were really bad and you knew it
BUT the op has known broken motor mount- Im guessig front side (front of car/l side of engine but called front mount)

get the car moving and you may get shimmy and shake!

JD- ck the motor and trans mounts plus steering parts for you shimmy
If the rims got bent there was other hidden damamge...
was it from a big curbshot or pothole city is where you reside?

Broken motor mounts will cause a rough idle too. I'm with everyone else you may have suspension issues too but motor mounts first!!
