if you are still using stock lug nuts i torque them down to 100 usually but aluminum lug nuts just torque to 90-95

According to my spec sheets and charts... at work 02+ ram 1500 with the 7/8 (22mm) are 135ft/lbs and that's what I've been torquing mine to aswell as customers trucks
Edit:
From alldata
TORQUE SPECIFICATIONS
1500 Series Lug Nut 9/16 X 18 with 60°Cone LD 183 Nm (135 ft. lbs.)
2500 Series Lug Nut 9/16 X 18 with 60°Cone HD SRW 197 Nm (145 ft. lbs.)
3500 Series Lug Nut 9/16 X 18 with Flat Washer HD DRW 210 Nm (155 ft. lbs.)

This question is a good one to explore. I will do a search re; this issue.
Has anyone come up with why the spec is so low on our trucks?
Thanks Guys!

Those are the same lug nuts i use on my lexus accually and you can tighten them tight however you will break the "Lug Key" before you mess us the lug so just be carefull. 100 ft pounds is plenty tight
I believe this is why..
Our torquing specs have to do with the material of the lugs, the thread/pitch size of the studs and the type of material of our wheels, not to mention vehicle weight. Over-torquing can lead to stretching of the studs, which over time loosen off the lug nuts or the breaking of studs as they've reached their maximum threshold over mating surfaces. The chances increase when it's gone over specs. With our hardware, torquing to 130+ft/lbs could be reducing clamping strength than increasing it.

yeah like i said id stick to torquing betweek 90-100pounds. Its definitly going to be tight enough without having to worry about anything but not to tight.
I'd contact the aftermarket wheel manufacturer (and lug nut manufacturer) and ask them what they recommend. What wheels and lugs are ya running? FYI: on my 06 with OEM wheels, I keep the lugs torqued between 90 and 100 ft lbs. Ditto for the Mopar locking lugs, even though they specify 115 ft lbs. Once you know the aftermarket torque, I'd recheck the torque until the lugs become seated. Also, don't ask me why (I have no clue) there is a torque variance between a OEM lug and a Mopar locking lug.
Lots of varied data on this one...
I'm attaching screen shots of the FSM, SRT-10 glove box manual, OnDemand that all show either 95 or 90-110 FT-LB.
However,
Wheel Torque Chart - Discount Tire
Shows 135 for the SRT-10 and the 1500.
Wheel Tech - Wheel Lug Torquing
Shows 135-145 for 9/16" studs
http://www.imperialinc.com/pdf/A_FastenerTorqueCharts.pdf
Is a generic fastener chart, but shows 120-170 (dry) for Gr 5 to Gr 8.

Here's a possible explanation; Dodge changed the required torque on 03s via a TSB. I haven't found one yet that technically covers our truck...
TSB 05-008-03 10/28/03:
"Install the wheel and pre-tighten the lug nuts in a cross pattern to: 70 Nm (50 ft. lbs.) then final the lug nuts in a cross pattern to: 135 Nm (100 ft. lbs.) and mark the wheel at the same location as the marked wheel stud. "
TSB 05-008-03
This TSB was superseded by
TSB 05-003-04 6/8/2004:
"Install the wheel and pre-tighten the lug nuts in a cross pattern to: 70 Nm (50 ft. lbs.)
then final the lug nuts in a cross pattern to: 183 Nm (135 ft. lbs.) and mark the wheel
at the same location as the marked wheel stud."

My wheels come off almost weekly, and I never torque them over 100. And I never find them loose.
I have the same issue with my CTS V...which uses the same lug nuts...they also recommend 140 lbs....which is just too much in my opinion. They also come off frequently for cleaning of the wheels and the wheel wells and running gear...so they get a max of 100 lbs too.
My five foot tall spouse would have to use a six foot long pri-bar to remove lugs torqued to 140 lbs.

My dealer told me about the TSB as previously mentioned. I felt that was a bit too much and continue to use 110ftlbs.

I will tell you this from personal experience. If you put on alum. aftermarket wheel you need to re-tourqe them after 50-100mi. I know becouse i had a wheel come of a 40mph on my other dodge 4x4 after putting new tires on.
$780 worth of damage to the backing plate and brakes.
There was absolutely no warning (ei. shaking, noise, etc.)
