This adjustable wheel lock temporarily disables your wheel to deter theft, and it includes a lug nut cover to prevent wheel removal. Rubber cushion helps protect your wheel from scratches. Ideal for trailer storage, but works with some vehicles too.

Specs:
Note: Will not work on trucks with dually wheels or on vehicles with low ground clearance.
Wheel locks, also known as Denver boots, were introduced in the 1950s as a solution for police to immobilize vehicles for ticketing purposes. While they're still used for that purpose in some places, you may want one to make would-be thieves think twice about stealing your trailer. Someone could still break into your trailer if it's not fully secured, but without the key and crank, no one is moving your rig with this wheel lock installed.
If you've never mounted one of these wheel locks before, it may take a little time to get used to the process. This lock weighs 17 pounds, which is lighter than it looks, but some people may have a hard time holding it up while installing. Because this lock can be a bit of a pain to install, it's probably not the kind of thing you want to clamp on every time you stop somewhere along your journeys, but it'll be perfect for slapping on once you're back home and ready to store your trailer.
To mount the wheel lock, unlock the adjustment covers near the handle and on the disc arm. There's a triangular keyhole inside each where the crank tool can be inserted.
Starting with the crank in the hole near the handle, rotate the tool counterclockwise to open the arms. Place the lock around your wheel, then use the crank to tighten the arms down by turning it clockwise. You should only tighten the arms a bit at first, then get the disc situated over your wheel's lug nuts. Insert the crank into the disc arm hole and and turn it clockwise to tighten the disc arm, then finish tightening the lock's arms.
Once you lock the adjustment covers back in place, you're ready to go! Store the crank inside your vehicle or toolbox until you need it to remove the lock.

These Tri-max boots start to show their age after a couple years. The barrel lock mechanism and cam device to open the access door for the specialty key are prone to fail. As these fail we are replacing with something else. PS: At $250 apop these shouldnt ever fail..
