Got new tires on TOAD ...
Very slight steering wheel vibration at exactly 25 mph ... not slower or faster mph... Other speeds no vibration all the way to 70 mph.
Would that be balance or alignment?? Or either. Thx M44
I can take it back to installer, which I will, but would like input first ...

Hard to say, but new tires can act a little strange until getting a few miles on them.

No vibration before new tires ... also, perfect straight line drive with no hands on wheel before new tires, no left or right pull.
Not sure if new tires will effect alignment, but BMW tech says AWD should not need alignment if we install new tires.

Tire and wheel may not be mounted correctly or loose. Look at each wheel for lug nuts not being equal, this works if they are open ended.

A ship I was in started vibrating (sort of hopping up and down) at 13 knots, but not at lower speeds or faster speeds than that. It was called, "Honeymoon Revs".
The cure was to avoid going at 13 knots. So in your case avoid 25 mph ?

Certainly sounds like a balance problem. Bad alignment does not cause speed specific tire vibration, more typically it causes abnormal tire wear.

Loose wheel/s. Alloys need to be re torqued, sometimes more than once. Could have lost a weight. Some balance machines are better than others.

Well, new tires installed today ... I was coming down on balance, but want to ask here as many of RV.net guys know more than my 'little bit' about tires ... Will have installed balance again ... and see. If not, will have them put on a new set. Mfgr has a 30 day exchange if you don't like the tires - so will exercise that option if the installer can't settle the vibration.
I'm more worried it will increase if I jsut let it go and skip the 25 mph issue, but no matter, it still means something is amiss with these tires.
An aside: HA, our housing community has a 25 mph speed limit, so of course, we vibrate at 25 mph --- go figure.
