Loose lug nuts!!!

I just switched to 15in D5 beadlocks on my Z and keep getting loose lug nuts after driving only a few miles. Anyone else experience this? I've tried different torque specs.

What torque specs? 140ft lbs is what the manual calls for.

And if you're already using 140 ft-lbs for torque, next thing I'd check is that you have the proper lug nut dimensions for the wheels, specifically the dimensions of the taper.

What is the thickness of that wheel in the lug area compared to stock? I think your lug nuts may be bottoming out.

I think this guy is right. The website says you need conical/tapered lug nuts:

This thread has some size recommendations for VMS drag wheels, which also require a conical tapered nut:
