I always used to keep a metre odd of steel pipe in the boot to fit
over my socket set wrench, for just that reason. I often had to
stand on it - pushing downward so as not to lift the car off the
ground - in changing wheels that had been last put on by the tyre
changing lads.

The tyre place I use always uses a torque wrench and they adjust it
to match the car.
On a car I borrowed once I had to put the jack under the wheel wrench
to undo a nut, saves having to carry a long bar.

I remember watching a tyre place put two new tyres on my car, refit
the nuts with the air wrench and then "test" the nuts with a torque
wrench. I made them slacken the nuts off and do the job properly.

These guys back off with the torque wrench and then tighten it.
The do use the air wrench to put them on but it doesn't do them up
tight, they are usually adjustable to stop them over tightening.

You shouldn't back off with a torque wrench, they were never designed
for that.
