One wheel does have a bit of runout side to side.

You'd have done yourself a service to have mentioned this early on. That's
a guarantee of vibration. There are ways to dress the wheel, including
turning it over to gain access to the opposite side if necessary. It's
unlikely you'll get the wheel to run smoothly as long as it is not parallel.

Before you do any dressing, locate the wheel such that the inside runs in
the best condition, so it may not need dressing. In a situation like this
I like the internal flange to be integral with the arbor, so it causes the
wheel to run true on one face. It makes correcting wheels much easier.

Get creative----with the side guard removed, use a piece of stock and a
clamp of sorts to build a temporary work guide along the side of the wheel,
adequate to support a diamond. Using a light touch, remove the highs from
the wheel side. If it improves the operation, it will become noticeable
as you dress, running smoother and smoother as you remove the thicker
portion of the wheel.
