What exactly do tow dolly wheels look like?
I’ve seen what you are referring to or at least I think. They have two little wheels, the size of golf cart wheels as a set for each side. Their spindles are welded to a mini frame that accommodates two square stock tubes that slide in the mini frame on one side and go across to the mini frame on the other side. They are strategically designed with a distance between them that accommodates the tires/wheels of the disabled vehicle (The wheel/tires sit on the two square stock tubes running across under the vehicle from side to side, mini frame to mini frame) This is only for short distances at low speeds. It goes without saying that after this end of the vehicle is lifted into place as just described, the wrecker then lifts the other end as usual and away they roll. I drove a couple of wrecker both small and large (twin screw Jimmy) back in the early 70s. Much has changed since then! Usually now they send a tilting flat bed with winch and drag it up on go.
