The world knows I'm not a perfectionist but my local tyre centre on refitting a road wheel asked a question i have not heard before. What poundage/psi/torque should the wheel nuts be set for? I have no idea and the Workshop manual - wheels and tyres section 5 - p6 is silent on the matter. The fitter tells me that the threads are thin and weak and to over-tighten will cause them to strip with disastrous consequences. Any ideas?

The wheel brace is designed to give the correct torque, so tighten up with that. I have always insisted on that since I was marooned in a quiet French country lane with a flat tyre and unable to undo the wheel nuts with my wheel brace. I don't know the torque but guess it would be no more than 60 lb. ft.

Unless you are the Incredible Hulk or Big Kev, as tight as you can will suffice. I am not a lover of air guns to do up wheel nuts.

Torquing wheel nuts used to be critical when wheels were attached to large drum brakes (on some types of vehicles) as uneven tightening could cause distortion of the drum (For eg. Peugeots. 203, 403, 404.) Some drum braked cars had the wheel studs held in the drum face and the wheel hub was integral with it. These drums could distort under uneven torquing.
I wouldn't worry too much about front disc braked P5s as the wheel bolts to a flange and similarly for the rear drums (which really do belong on the Titanic)
Just don't over tighten them. Stantondavies is on the money.

Wheelnut torque setting is 65 lb.ft.
If checking tightness they should be backed off, and then tightened to that figure.
