One more thing. Back in the "old days" 50's and 60's, many truckers did their own tire changing (9.00 x 20 and up). Many of them would air the tires, off the truck by standing on the wheel from the back side. While I don't remember any that got killed that way, I do know that some lost their teeth and also, got scared up. That's why I said they have to be mounted on the axle.
