how does the tire attach to the bottom? is it just a large bolt with a wingnut like thing? if so drill a hole in the bolt part after the wing nut or whatever and put a lock on their. your probably better off using a lock like this
its what they use in storage units dont know how it holds up to sawzalls though. Maybe keep it on your roof locked up, its much easier to spot someone stealing a tire if its on the roof. or you can just keep it inside your jeep, but i would worry about people smashing windows to get it. Weird that its kept under the jeep, I know on my friends 94ZJ its kept inside, and on my 04Wj its kept inside the jeep too.
What year jeep do you have?
