Rigs & Wheels...How to do it?

Alright, Ive got this rig, its a robot body floaing between two wheels. Im trying to figure out how to have the rig work, and have the wheels turn(without taking off away from the rig) and the wheels are the same object as the body.
Thx in advance

Aw, NM, i figured it out. just shift select the wheels(seperated them) then the armature. parent as an object(as compared to armature)…now it works fine thx
