ABSTRACT:
Replaceable tread or track belts on tube tire carcasses can be changed in the field and elsewhere by venting the pressure within the tube tire carcass, subsequently creating a partial vacuum within the tire carcass sufficient to cause it to commence collapsing, and then, while maintaining the vacuum constant in the carcass, physically depressing the periphery thereof at circumferentially spaced intervals to convert the outer circular surface of the carcass to a polygonal configuration that allows the circular belts to be conveniently changed.
