Abstract
A pneumatic tire and a mounting system therefor, having constructional features designed to provide optimized operational characteristics. The tire has a low aspect ratio .lambda. and a low height ratio .theta. conforming substantially to the relations .lambda.=0.236/.theta. and 0.32<.theta.<0.39. The mounting system includes a vehicle axleborne drum and a pair of ring members adapted to be securely fastened to the drum, each ring member defining a bead seat, a bead restraining flange and a sidewall-supporting extension, and the ring members being adhered to the tire at the beads and the lower sidewalls. A layer of a suitable sealant at the juncture between each ring member and the drum renders the joints airtight. The tire includes a single ply radial carcass the turn-ups of which terminate in the lower sidewall regions of the respective adhesion zones between the tire and the ring members, and each of the beads is reinforced by a relatively thin, lightweight metal member in the form of a single loop having no free ends. A novel valving system for the tire, including a passageway in one of the ring members covered at one end by a quantity of a sealant having self-sealing properties, is also provided. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
