Personally, I have been very tempted to do this just getting in/out around the farm. In fields etc. On the highway I always wear a belt but damn that chime is annoying.

Use a heavy rubber mallet, hit the drum on the farthest inboard edge of the drum in two spots across from each other. I clean my drums every tire rotation so mine always come off easy. But this is how I get the drums off transport trucks. Edit: There are no retaining clips or any device holding the drum on other than the wheel + lug nuts.
