Fellow Tiger nuts:
May I add a humble opinion to these apparent "low-ball" wheel stud/nut
torque specs:
There is more happening here than just applying enough torque to keep
the wheels on the hubs under all conceivable conditions: You also have
to consider the potential for distortion of the parts in the
wheel/disc/drum sandwich. Lots of brake discs have been rendered useless
from distortion caused by an over-eager wrench jockey with a hammer gun
on full chat.
The auto and wheel manufacturers have to have done the research to find
the torque value to keep the parts from premature wear, freedom from
wheel-jettisoned law-suits, and unhappy families of dead customers.
Follow the recommended torques!
My humble opinion.

Recommended Torque Specs
3/8" UNF 35 to 40 ft/lbs
7/16" UNF 50 to 55 ft/lbs
1/2" UNF 65 to 70 ft/lbs
12mm 65 to 70 ft/lbs
14mm 75 to 85 ft/lbs
Note: These are dry specs
Found this on the Superlite wheels web site:
Wheel Nut/Bolt Torque Setting
3/8"UNF. = 35 ft. pounds
7/16"UNF. = 50 ft. pounds
1/2"UNF = 60 ft. pounds
10x1.25mm. = 35 ft. pounds
10x1.5mm. = 35 ft. pounds
12x1.25mm. = 60 ft. pounds
12x1.5mm. = 60 ft. pounds
14x1.5mm. = 75 ft. pounds
16x1.5mm. = 90 ft. pounds
