Lug nut torque specs

[Reaper85]

Dealership over here do sent even retourque lock nuts. I'd assume they do on initial instalation but not on retourque. They said it's way to easy to break the key.

My Manual says 110 ft-lbs for the Blue tint lugs . So that's what I torque to.

Since I am a 150 lb. weak sauce, I tighten them by giving it a good right foot stomp (in my old car).

[flyinglow57]

Always did 100 lbs on aluminum wheels and 120 on steel wheels. Haven't failed me in the 5 years at Firestone and 15 years since then.

[JCunningham]

blue tint is 110ftlbs silver tint 140ftlbs as per 2012 manual. the 2013 manual pdf from chevy only lists 110ftlbs for all in the specs

[3rdgen3]

My 2012 manual says 140 ft lbs for alloy wheels.

I torqued my wheels to 110ft lbs prior to reading the manual and I had a very slight vibration that went away after retorquing all my wheels to 140.


I'll stick to 140.

[NC_SS]

I run 110 lb-ft

[JCunningham]

so every ones getting different manuals for the same car?
from the 2012 owners manual Part No. 22825335 B Second Printing ©2011 General Motors LLC. All Rights Reserved. i received with my 2012 2SS build date 02/23/2012. it's also the one on the GM website for the 2012 Camaro

Wheel Nut Torque
Wheel nuts with blue tint cone seats 150Y 110 lb ft
Wheel nuts with silver tint cone seats 190Y 140 lb ft
says nothing about alloy or steel wheels. my SS came with the standard SS Aluminum wheels with lug nuts that have blue tint on the cone seats. there for 110ftlbs

everyone for your replies!

My 2011 Camaro Owner's Manual states that the Wheel Nut Torque should be set to 190 N-m | 140 lb ft:



It does not state anything about Blue or Silver Cones. However, the OE lug nuts from my OE wheels do have a Blue tint :



The following is the Gorilla lug system I purchased:



Based on what my manual states, I decided to let Discount Tire torque them to 140 lb ft...which is what their computer showed as well. I also found the following comments in other threads in this forum regarding this topic to further support this setting:

=========================
The 2010-11 Camaro uses 14mm x1.50 studs. The GM spec for this is 140 ftlbs, or 190 N.m

Chev Traverse, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m
Chev Tahoe,Suburban, GMC Youkon & XL 1/2 ton, 14mm x 1.50 spec from manuals - 140 ftlbs / 190 N.m
Chev Silverado 1/2 ton, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m
Chev Express van, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m

GM vehicles that have the torque spec of 100 ftlbs / 140 N.m are cars that use the SMALLER 12mm x1.50 stud. This includes the Corvette

The 2010-11 Camaro is the only GM car that uses the 14mm x 1.50 stud. All other GM cars use the smaller 12mm x 1.5 stud.

=========================
Camaro aaaannnd CTS aaaannnd other cars use M14x1.5 bolts/nuts...

GM began to change lugnuts for Camaro in 2012 per owner manual:
GM lugnuts with SILVER color ON THE CONE: 190Nm- 140ftlb
GM lugnuts with BLUE color ON THE CONE: 150Nm- 110ftlb

Torque is not the target of what the wheel or whatever part needs... its clamp load. The only way to gaurantee you have proper clamp load is to test it on a torque-tension test machine.... Most important area of concern is the cone seat (ie dont get anything wet/oily on it when you go to tighten). If you are not using GM lugnuts, then onus is on you..

=========================
The part of the lug nut that touches the wheel is the CONE. or CONESEAT... on GM lugnuts and many others... its a 60degree cone. The lugnuts on Camaro aluminum wheels have a decorative stainless cover on the part that touches the wrench (hex side). Lugnuts on steel wheels are constant color throughout.

The OM is not a misprint. Perhaps your dealer should look into it a little more... not sure where he drew that conclusion.

as far as aftermarket lugnuts... same as anything esle aftermarket... the onus is on you!

=========================
For a long time GM CARS were M12 lugs with the 100ftlb... and GM TRUCKS were M14 with 140ftlb.... what many don't realize that that now, many of the CARS are M14 lugs... and pay attention to the Owner Manual for proper torque!

=========================
It could have either blue or silver... and the blue or silver is on the cone of the NUT, nothing to do with the wheel. For a 2012 ZL1, it "should" have blue... If a car is 2010/11, it should only have silver ( on cone) nuts.

The blue is more slippery of a coating than the silver, hence the need for less torque... and thereby recieves same clamp load either way.

=========================
I was told when I asked this question concerning my aftermarket wheels and nuts that it is the studs that determine this. I torque to 140.

=========================
2015, 2014, 2013 all say 110 lb-ft.

2012 is a little weird though, and is 110 lb-ft for wheel nuts with "blue tint cone seats", and 140 lb ft for silver tint cone seats (like the 2011s and 2010s)

2011 and 2010 are 140 lb ft.

Sources: Chevy website service manuals

=========================
Ok, the torque is 140 foot pounds, or 190 Newton Meters -
Don't go by "general" or "standard" torques. Read the fine print in most of those guides, they alway say to torque to factory specs.

The Camaro uses 14mm x1.50 stud. The GM spec for this is 140 ftlbs, or 190 N.m.
Chev Traverse, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m
Chev Suburban 1/2 ton, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m
Chev Silverado 1/2 ton, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m
Chev Express van, 14mm x 1.50 spec from manual - 140 ftlbs / 190 N.m

Ok, GM vehicles that have the torque spec of 100 ftlbs / 140 N.m are cars that use the SMALLER 12mm x1.50 stud. This includes the Corvette! Seriously, the Camaro is a big heavy car! It does rank up there with the trucks. The Camaro is the only car that uses the 14mm x 1.50 stud. All other GM cars use the smaller 12mm x 1.5 stud.

=========================
From Gorilla's site!

TORQUE GUIDELINES
A calibrated torque device must be used to achieve proper torque
specifications.
Use Original Equipment Manufacturer’s torque specification. If it is not specified in the vehicle owner’s manual contact the vehicle manufacturer. If the Original Manufacturer does not provide a specifi cation, check with the aftermarket wheel manufacturer for a specification.In the event that neither the vehicle manufacturer nor the aftermarket wheel manufacturer give you the specification, the following MAY serve as a guideline
for passenger cars and light-trucks only:

Stud Diameter Torque Range (Ft/lbs)
12MM 75 - 85
14MM 85 - 95
7/16” 70 - 80
1/2” 75 - 85
9/16” 105 - 115
5/8” 125 - 135

=========================
Gorilla states to follow OEM guidelines, which is 140. IF, there are no guidelines available Gorilla states you MAY use the specs as a "guideline" in the chart which is 85-95.

=========================
The 2010-11 Camaro uses 14mm x1.50 studs. The GM spec for this is 140 ftlbs, or 190 N.m.

I was told when I asked this question concerning my aftermarket wheels and nuts that it is the studs that determine this. I torque to 140.

=========================
it is the same size stud and lugs that aer on the silverados and tahoes the torque is 140

I belive 140 FT LBS ( as the manual says) is the correct torque.......
I have a 2008 Tahoe and had a 2001 Youkon...they ALSO call for 140 FT LBS (as in their manuals)........
I have a small trailer with 15" Alum. rims in the manual it calls for 120 FT LBS torque.

=========================
I just installed my Gorilla wheel locks and torqued them to 140 ft lbs. When removing the factory lugs, they sure didn't feel like they were torqued to 140 but I didn't actually take a torque wrench to them when removing them. I also called Discount Tire by the way and they also said 140.

=========================
Dia.of the stud or lug has a lot but not everything to do with its Torque.

=========================

This is definitely a CONFUSING topic...to say the least.

[My 5th]

I have the same Gorilla system. Discount Tire always torques to 140 and so di I. As each lug is a lock the torque load is spread more evenly around the circumference of the nut, so I believe there is less likelihood of stripping or breaking something. However I wouldn't use an air wrench on them...too much herky jerky.

Cool... are those lighter than the stock ones?

These are the only ones I have taken so far:

VERY much so!!!

The installer told me to lift one up with one arm to feel how much lighter they were...

Makes sense...thanks!
