OK to lube wheel bolt cones?

[BYprodriver]

Porsche says do not lube "cone" to wheel contact area. I believe the purpose of the cone is to reduce friction between the lug bolt & wheel surface. I use a thin coat of anti-sieze on all lug bolts/studs & if I had the problem you do I would lube under the bolt head also. Basically you want the "cone" to not move & the bolt to be low friction for a true torque reading. I drop my install torque to 90 ft.lbs. due to the reduced friction.

I use a few drops of oil on lug nuts/bolts, it doesn't change the friction and resulting torque as much. Nothing between the cone and wheel.
