A tire having a reinforcing sheet of tubular knit material stretchable during shaping into a toroidal form. The knit material provides openings for striking through of the liquid reaction mixture of elastomer forming material used in molding the tire. The sheet of knit material may be folded over spaced-apart bead rings and overlapped to provide multiple layers. The tire is molded on a core supporting the reinforcing sheet and bead rings with the strands of the knit material straightened out and in tension at the time of cure.

Tire and method of reinforcement

A cast or injection molded tire having a reinforcing sheet of netting material providing openings for striking through of elastomeric material during filling of the mold. The process of making the tire includes shaping the sheet of netting material by stretching and thereby orienting the strands. The shaping is done at elevated temperatures and then the netting material cooled in the shaped form. A mat of overlapping sheets of netting material may be used with the strands being multidirectional to provide uniform sidewall strength. An overlapping breaker ply of netting material may also be used to connect two mats of reinforcing sheets on opposite sides of the tire.

Fluid dispensing apparatus for a tire wheel assembly having a wheel supported ring member with a diameter greater than the wheel rim diameter and less than the tire tread diameter. A fluid chamber is provided radially inward of the ring and an opening in the ring accommodates a passage leading from the fluid chamber to the radially outer surface of the ring. A closure for the passage extends radially outward from the surface of the ring for opening upon engagement by the tire during deflation and for dispensing fluid from the fluid chamber through the passage to the radially outer surface of the ring. The closure may be of a flexible material to withstand impact loads without rupturing during operation with the tire in an inflated condition but having a limited tear strength to rupture and release fluid under circumferential shearing forces during operation with a deflated tire.
