Lug Nut Torque

[Kickstart173]

I am getting conflicting info about lug torque, I have a 2008 Sierra with 20" aluminum GMC wheels.

I've called several Dealers and several Tire dealers and have been given 4 different specs 80 to 120 ft lbs.

Anyone know the correct lug nut torque for these aluminum wheels?

Thanks
