What's best tire lock?

I just lock my hitch with a simple bar pass-thru lock when in campgrounds. Use a claw when in the boonies.

This may seem like a stupid observation, but it seems to me, for a wheel lock to be secure, you should have locking lug nuts.  These are standard size trailer wheels, so someone could pull in with a trailer scissor jack and portable rachet gun, raise it up, put a trailer wheel on and take off.  I realize you have to defeat the hitch lock, if you have one.  I can see this happening when boondock camping, without others around.  

Would take them awhile, I think that's the biggest deterent. If they're intent on stealing it, they probably will no matter what you do. The T@B is so unique though, I'm not sure it's a good candidate.

Before moving, when my T@b storage was more iffy, I used a hitch lock and this wheel lock: http://www.amazon.com/Trimax-TWL100-Ultra-Max-Adjustable-Wheel/dp/B003E1GLSM/ref=sr_1_5?ie=UTF8&qid=1449713126&sr=8-5&keywords=trimax+lock  It has a cover over the lug nuts which alleviates the concern jdargis mentioned.  Where I live now, I am not as concerned for security at the new storage place but I still use the hitch lock.
