1997, small shimmy while driving
 

I hope this is the right place for this.
My old mags and tires had a small shimmy around 70 Ks and up, so I needed new tires so I bought new mags too, (Alcoa's) the tires are 285/75/16 (hankooks) the mags are 16/8", so I still have the shimmy, you notice around 90 Ks and up, feels like the rear, I can feel it in my feet.
My question is, could an axle be bent? or a front or rear bearing cause this?
To me my truck should be glass smooth to drive.
thanks.

still alot of factors. what happens when you apply the brakes? does the shimmy increase or decrease with speed?
any service done on the bearings?

A lot of this should be looked at on a lift .
The auto balancers work very well , but get everything els done 1st .

It just gets worse tha faster you go, say from 90 Ks and up, no difference when breaks are on.
No work done to the bearings, just look for play and there is not much in the bearings.
