I drive about 7k per month pulling trailers.
I had this happen many times. With the lug nuts that have washers, the book says to torque to 140. After wrecking 10 rims and replacing all the studs and lugs nuts a few times, I was on the tow truck one day and asked the driver how they keep their lug nuts tight. He said to torque to 200. I have broken a couple of studs at 200. I use 185-190 and have never had a problem since.
