If you don't use a criss cross tightening patteren they can come lose. Also tourque to specs.
If the back of your rims have rust on them, smal flakes could be working off causing what you describe.
Dont use lock-tite.

Yes Espen is right, take a wire wheel and clean the back side of each wheel and rotor to make double sure there ain't nothin inbetween!! May want to get some new nuts as well!?

I second the new nuts. Also, I overtighten them, i know some say it is not good, but it is better then having you nuts come loose and the tire fly off!
Actually I am known for over tightning everything and breaking bolts. I have broken many wheel studs!
ooppss!

Here's part of your problem: 17x40x15
Those monster tires are exerting WAY more force on the lugs (and spindles and bearings, etc) than they were designed to handle.
Find out the proper torque specs and use a torque wrench to be sure you are tightening them properly. Over-torqueing can stretch the bolts to the point that they no longer have any elasticity. Without that the bolt loses it's ability to hold a load properly. (It's the reason most engine builders will replace rather than reuse head bolts. Proper torque is critical to that application).

Harry, I have 35" meats now. It happend on both. I am planning on taking it appart and wire brushing the back & rotor, & replacing the posts & lugs. Thanks for all your help, there in nothing worse than hearing those lugs falling off and feeling the tire wobble free (happend twice now). Luckly the tire stayed on because the hub comes out so far.

I had a similar problem after I got my new centerlines. Seems the shop used generic type nuts, normally I wouldn't think twice about that. But my wife blew all 6 off the right front! Tire didn't come off either!. Anyway switched to Gorilla Brand & they've never come loose again!
