Expert Reply:

I attached a chart that has all of the recommended lug nut torque specs for trailer wheels. Based on your studs being 1/2 inch, your wheels being 15 inches in diameter, and your lug nuts being coned you would want to torque your lug nuts to 90-120 ft lbs of torque.

It's recommended that you tighten them in a star pattern. And then recheck them after about 50 miles of driving. I've lost several lug nuts by failing to recheck them after driving so I would strongly recommend you check yours after driving.
