Haven't pushed past 75mph yet. Oddly enough the vib seems to disappear at
speeds between that...or I might be imaginging it. Never had an off balance
tire act this way before.

Do they check the balance at multiple RPM?
The reason I ask is I have tire pressure units inside these rims. They have
a counter balance to offset their weight. I'm wondering if all these factors
are not visible at lower RPM on the balancer and then need to "crank it up".

it seems possible that the tires were not balanced properly at install -

just a thought

does the vibration go  away above 75  : D

We'll I just asked about small play I feel in the front end but now let
me
tell you about my new wheel/tires too.

Old setup was 14R185 with no vibration or problems in the front end.
Only a
"slight" pull to the right, but nothing alarming

Now I just put new 225/70R15 with alloy rims on my 1986 Westy (2wd).
I've
now got a vibration (wheel wiggle) from about 55-75mph and it pulls
considerably to the left. Enough that I will take it for a front end
alignment tomorrow.

Most vibrations at a particular speed or range in my experience have
been
related to wheel wear or balance. We rotated the new rear tires to the
front
to eliminate the thought of a bad tire out of balance, but the vibration
(wheel wiggle) is still there.

Any thoughts before I take this to my alignment guy and start bugging
him?
Can the larger tires (obviously more weight) pull anything out of place?

on their trail. Many are the travelers I have spoken to concerning
them, describing their tracks and what calls they answered to. I have
met one or two who had heard the hound, and the tramp of the horse, and
even seen the dove disappear behind a cloud, and they seemed as anxious
to recover them as if they had lost them themselves." - henry thoreau
