Im using the spline ones

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!

if you are still using stock lug nuts i torque them down to 100 usually but aluminum lug nuts just torque to 90-95
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.
Would the torque be the same on aftermarket rims as it is on oem rims 95lbs?
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

Is a generic fastener chart, but shows 120-170 (dry) for Gr 5 to Gr 8.
