M1101 lug nuts

I recovered my M1101 from Ft. Campbell last week and everything went well, except for the constant rain. Glad I carried a rain suit to wear while I got the temporary lights installed and tires aired up. Now that I have it home I want to install the aluminum wheels from my 2009 Chevrolet 2500 in order to lower the bed height a few inches. I know several others have installed these same wheels. My problem: The lug nuts from my 2500 will not fit the trailer due to different threads. The lug nuts on the trailer do not have as deep a taper as the truck lug nuts, which means the lug nuts don't match the taper in the wheel lug holes. Will this cause a problem keeping the lugs seated securely or "wallowing" the lug holes in the wheels? What have others done when installing Chevrolet 2500 aluminum wheels on their M1101/M1102 trailers?

The M1101 uses a 9/16 lug nut. If using a GM aluminum wheels, the lug nuts must have a "bulge taper" to seat properly. Harleyhouse has the best solution, although I found mine locally at a custom wheel store.

The oe are just open face conical seat if you are using the factory plain steel wheels. If using oe gm factory alum or chrome wheels, I would think they are still conical seats. Typically only aftermarket wheels need deep extended thread that go into the rim.

I can not tell from NAPA's description thread size?

Probably be safer to go with open end. Maybe buy one of these to test:

I am not sure on the back spacing and hub circle specs off hand. Probably listed here on ss on another thread. Same wheel also for hmmwv.
