That should be listed in the owners manual. Stick to what it recommends. In order to avoid chances of warpage I would work up to the proper torque in a couple or three steps. I figure if it needs to be torqued it's worth taking an extra minute. Then again if you have your truck in anywhere to get anything done they won't be anywhere near that careful with it. Your mileage may vary...
Till' my 1/2" Ingersol Rand Gun is just about to stop turning...... If it works for the tire shops, it works for me. I've never torqued a lug nut a day in my life.
I just run them in with an impact. I do top and then bottom lug then go around till the gun stops and let it hit for a second more or so. You will get a feel for it.
Tightening the crap out of them is all well and good when your working in the shop. I had a tire guy tighten my lugs so tight on my truck that when I got a flat on the side of the road I couldnt budge any of them with the factory supplied wrench. I ended up having to call a buddy to come pick me up, go get a four way and a big peice of pipe for leverage to get them off. So now I usually just get them as tight as I can by hand.
sometimes its just like that even if they arent tight...... i would likle to see most dually pickup truck owners change a flat tire o nthe side of the road wether it be a front or rear tire......... if they havent been off and havent had the hub surfaced antiseized they will not come off.... all those duallys are "hubcentric" and the steel wheels rust on, and the aluminums oxidize on. i have to beat them off all the time with a sledgehammer at work once you get the lugs off. an average person o nthe side of the road would never get it off......
