A fellow gmc owner in Germany asked about the wheelnut torque The manual states 250 ft/pnd
It seems like a lot of torque What do you use?

250 is correct because of the large flat washer built as part of the nut. This washer requires additional torque to overcome the additional friction of the washer. That said, a lot of people use a lower setting. I never did when I had steel wheels.

G'day,
I'm going to answer my own question! I did some more digging and found this:
Wheel lug nut torque
- Use torque wrench @ 130-150 fi-lbs in sequence
- Not maint. Manual value (250 ft-lbs): studs will stretch & break
- Radial wheels only w/radial tires
Which was in a document entitled:
WHAT EVERY GMC OWNER SHOULD KNOW by Dwayne Simmons and can be found here:
http://gmcws.org/Tech/dsimmons/required_gmc_knowledge/required_gmc_info.html
That's good enough for me!

G'day,
Back on September 20, 2012 in Forum Message #185150 I noted; "The manual is incorrect and was revised to one hundred and fifty foot
pounds (150)."
Rick Denny commented "Which is a reasonable number when you use anti-sieze lubricant, which you should."
Unfortunately I NOW have a problem with that statement because I wanted to provide a source for my statement and I can't seem to
find out WHERE I got 150 foot pounds from. I checked MM X-7625, MM X-7725 and the Wheel and Tire Service Bulletins and found NADA!
Anybody got any ideas where I might have found that info!
Regards,
Rob M.

Gene,
I got an OFF NET comment from a long time GMC owner who is technically savvy expressing concern that 150 ft lb might be too low and
that he felt 185 ft lb would be better.
I decided that it might be a good idea to reach a consensus so I sent in the Lug nut / Wheel nut Torque email requesting comments.

Gene,
Please "say" the same thing over on the Lug nut / Wheel nut Torque email. When Yanks want to search for the info 5 will get you 10
they'll call them lug nuts! ;-)
Appie, no criticism meant!

There will always be conflicting opinions on lug nut/stud torque values. A
9/16" grade 8 wheel stud is definitely over torqued at 250 foot pounds
regardless of what kind of nut is used. With eight such studs securing a
steel wheel the combined clamping force is enormous. Any fastener stretched
beyond it's point of maximum elasticity is being set up to fail at some
point. There are a number of errors in manuals printed by GM and I believe
that this is one of them that slipped by the technical proofreaders whose
job it is to catch these errors. Just what I think. Your opinion may vary.
