I had to look them up on the "net" to see what you all were talking about. Yup, I've seen these, but not on motor homes. Seems the latest 'fad', which is gaining momentum where I live, is to put those tires/wheels on single axle, single wheeled pick-up trucks and cars so the tires extend beyond the fender. I hate that every time I see someone who has done that and wonder why they don't get traffic tickets. It's actually a danger to traffic behind them, as those tires can easily pickup road debris (like rocks and pebbles) and sling them into the vehicle behind them! Personally, I think they are stupid!
