I don't torque wrench wheel nuts, just like the average garage doesn’t either. It's only the pedantic that do it. Sure it's a good idea but it can't be too necessary.
I noticed that Bob Jane definitely uses a torque wrench on them. I don’t think they do it strictly correctly as they rattle them on then check them with a torque wrench. I suspect they are only concerned with under-torquing rather then over-torquing, and as such are just making sure that the wheel doesn’t come off.
I recall that there were come cases of busses or trucks were a wheel has come off after being rattled on and coming loose later (due to long air hoses causing them to under-torque?). The wheel fitter was found liable and I think the industry responded by ‘checking’ the torque manually with a torque wrench after hitting them with the rattle gun.
