Bad tires? If you have the luxury to swap with "good" tires, thats one way of eliminating if its the tires or something else.

Alignment? Have checked.

Unbalanced tires? Have checked.

Stuck caliper(s)? Chk slides/calipers. Do wheels overheat? Smell burning rubber?

(all of above related to vibration transmitted to steering wheel)
