new wheels and tires (vibration at 55mph over)

I had new wheels and tires put on my '06 tacoma. I am having trouble with vibration when running at highway speeds (55-70mph). Does anyone know what might be causing this? My wheels are 16x8 helo he842 with 265/75/16 nitto terra-grapplers. Any help would be helpful.

 

maybe the tire balancing? just guessing.....

 

yeh that sounds like they were not balanced right. Does the vibration stop after you get above 70.

 

get the tires "roadforce" balanced, and also check to see that the lugnuts were torqued to spec.....87ft.lbs. i think after they are roadforced, you will be good to go.
