Closed tube simplified radial tire, tire/rim assembly and method of making same

Abstract From the Canadian patent

In a tire and rim assembly a high pressure pneumatic tube tire formed of a single closed toroidal ply the cords of which are angled to the circumferential direction of the tire and a single belt ply of opposite and lower angle to the circumferential direction of the tire. Anchoring means such as one or more inextensible hoops are encompassed by the base area of the carcass ply to promote lateral stability and to provide engagement with the rim. Alternatively, the anchoring means may be eliminated by bonding the tire to the rim. The tire may be assembled on a conventional cylindrical tire building drum or upon the rim itself.
