Actually, you will want a slight "wet" torque. In fact, I repair class 8 trucks. And we are instructed by a vendor that supplies us with suspension and tire equiptment, that when we install new lug nuts we use one to two drops of oil on the first three threads, then torque to 500 ft. lbs. If you torque the stud dry you actually cause a slight bind and stretch the stud ever so slightly. It actaully distorts the stud and weaks it at the same time destroying any chance of real long term integrity. We have had two wheels come off due to someone not "wet" torquing the studs.
Your Jeep is not a class 8 truck,the torque values for the lugnuts are for dry threads.
