I've never seen a garage torque up wheel nuts.
a wheel/tyre/geometry place 30 miles from here does as standard. theyre about one of the only places i trust (unfortunately they cant always balance wheels properly but their geometry work is spot on)
Howard. i love it when you pass the half way point in a big job and have to get the torque wrench out. i love having elsawin for working on VAG stuff as it gives you all the NM settings.
as for wheels, of course its not life or death to use a torque wrench, but if you want 101% dependability (like i expect from my cars) then i do it.
ie when you changed the wheel for the woman, imagine if the last person had gone totally mental on the wheel nuts, you tried to help and one snapped when taking it off etc.
