E90 ('06 3-series) Lugnut Torque?

I'm not sure what your car requires, but my E36 Owner's Manual says the proper torque is 81 lb.ft. or 110 Nm, if you are metric centric.

Yeah, I don't even botrher to look it up anymore. I just torque all aluminum (alloy) wheels to 85 lb-ft. and all steel wheels to 100. Beats the hell out of whatever the airpower impact wrench jockeys spin them up to. In my mind, even-ness of the tightening is more important than the absolute accuracy to a pound or two.

YTMV,
