Interesting. The Porsche listed figure for wheel nuts is 130NM. I have done the new nuts up to 110NM to be a bit on the safe side. I'm slightly reassured that your tyre fitter said they could be lower as well. Out of curiosity, did he give a figure for this?ORIGINAL: ChasR
I was told by my tyre fitter to torque alloy nuts low. When I queried them coming loose he seemed to think it would not be an issue. Maybe I was lucky but on the times I worked on my S2 after that the nuts never came loose.
If you think Porsche nuts are bad you should see them on Triumphs (well, Stags and Dolomite Sprints). A combination of a high torque figure (it's around 130NM!) and 7/16" nuts with a UNF thread is a recipe for disaster (amazingly, mine were all original!).
