Tires? Balance or Alignment

[monkey44]

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 ...

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

tires should have been balanced when put on. I,d start there.

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 ?

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.

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.

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

was the vibration there before the tires if the answer is no than something to do with the tires
