Nothing scientific here and no PHD required, but, my 2 axle toy hauler has lugs that fit real nice in a 22mm socket.
When buying your socket, check the shoulder depth inside, you'll want something at least 1.5" to get a full grip on the nut.
I got a 22mm "Allied" brand deep impact from Tractor Supply. Fits perfect. Some lugs are solid and some have a chrome cap pressed on. The chrome cap types tend to be a bit of a loose fit.
