Question Lug Nut Torque for 2002 Ram 1500?

I just rotated the tires on the 2002 Ram 1500 QC, and I could not find the lug nut torque spec in the owners manual.
Anyone know what the torque spec is supposed to be? This has the steel rims, if that matters.

Default Lug Nut Torque

I have always used 90 ft. lbs. on all 1/2" Wheel Studs. Torque them up in stages in a star pattern and it will prevent a lot of warped rotors!

Default Torque.........

If memory serves, it is 100-110 lb/ft. It IS in the owner's manual, just not where you would expect to find it , can't recall offhand although I remember looking awhile.

I called the Dealer, and they said 135 ft/lbs!
The 2002 Ram has wheel studs that are larger than 1/2", but I'm not sure what size they are or if they are Metric or SAE?

Default Good luck getting e'm off if higher than 90 ft-lb !

From my experience in general, I've always seen torque specs for lug nuts are usually recommended at somewhere around 100 ft-lbs for cars and light duty trucks.

Anything over 80-90 ft-lb is usually a major pain in the a$$ to get loose later.

I always torque mine to 80 ft-lbs. (My personal preference, and I've never had a loose lug nut at that setting - ref. 1500 4x4). But I do check mine on occassion. If 80 ft-lbs seems too low to you, try 90 ft-lbs if it makes you feel safer.

I hand start each lug nut, then start to snug them down gradually using a star pattern with an impact wrench set to a low to medium setting. This makes them snug enough to safely lower the tire to the ground., then hand torque each one to my spec. with a Craftsman torque wrench which snaps/clicks when the torque is reached.

If you insist on following Mfr. spec., I would recommend putting a light coating of grease or anti-seize on the threads so you have a chance in heck of getting them loose the next time you need to rotate tires. This may start a big debate over whether lug threads should be dry (to prevent coming loose) vs. greased, but if you ever break off a stud because of a seized lug nut, you might decide a light coating of lubrication makes sense.

Maybe they say 135 FT-LBS for bigger trucks with larger studs, but that seems rediculously tight and difficult to remove later in my opinion.

Back when I first owned a car, I decided to follow the Mfr. spec of 100 ft-lbs. Even with greased threads, I had to use a breaker bar to loosen the lugnuts that had only been on for 6,000 miles, so I'm sticking with my 80-90 ft-lb policy.

I always use 100 ft lbs with Neversieze on the studs then re-torque after 100 miles of driving.

I use never-seize on the threads of the studs also, seems to work good. The factory had the studs lightly oiled.
I was not concerned about how tight the tire was as I was concerned about the brake rotors warping.
I had initially installed them at 80 ft/lbs.
I really should get a Factory Service Manual for the truck
