    Abstract: Disclosed is at least a two-layered chlorinated polyethylene film for use as an inner liner for a pneumatic rubber substrate or a tire, with an inner layer adjacent an inner surface of the rubber substrate comprising an adhesive resin; and an outer layer consisting essentially of chlorinated polyethylene containing from about 35 to about 50% by weight chlorine, a derivative of 2,5-dimercapto 1-3,4 thiadiazole as a curative, an accelerator, an acid acceptor, and optionally containing carbon black. The film is from about 5 mil to about 30 mil in thickness, and has oxygen permeability from about 10 to about 60 cc-mil/100 sq.in.-atm-day. The film containing carbon black typically has an intermediate layer of a thermoplastic elastomer interposed between the adhesive layer and CPE layer. Further disclosed is a pneumatic rubber substrate or a tire incorporating chlorinated polyethylene films of the present invention.

    Abstract: A pneumatic tire having an excellent cut resistance is disclosed, which comprises an annular crown portion constituting a tread, a pair of side portions supporting said crown portion, a pair of bead portions located at each foot of said side portions for fitting to a rim, a carcass layer composed of at least one rubberized cord ply toroidally extending between said bead portions and a liner layer disposed indise and adjacent to said carcass layer.In the tire according to the invention, a fault surface having an extremely low adhesion which intercepts the crack growth from the outside of the tire is further arranged in said liner layer at at least a part of a region extending between said bead portions.In the other tire according to the invention, for intercepting the crack growth from the outside of the tire, a low modulus middle rubber layer composed of rubber having a modulus lower than that of the adjoining rubber is further arranged in the tire at at least a part of a region extending between said bead portions.The growth of the cut damage especially given to the side portions of the tire is prevented by the fault surface or the low modulus middle rubber layer.

    Abstract: A bias-ply pneumatic tire comprises a tire cover having a thread portion, a pair of opposed side walls integral with the tread portion and a pair of opposed bead portions integral with the respective side walls and adapted to firmly engage with associated rim flanges of a wheel rim. Each of the bead portions includes at least one bead core embedded therein. The tire cover includes a bias-ply carcass structure composed of a plurality of carcass plies laid on a bias at a predetermined angle with respect to the midcircumferential plane of the tire. At least one of the carcass plies in the tire cover has its opposed ends each terminating, without being turned up around and anchored to the corresponding bead core, in a region between the corresponding bead core and a lower portion of the corresponding side wall while the other of the carcass plies have their opposed ends each being turned up around and anchored to the corresponding bead core, thereby terminating at a position adjacent the boundary between the side wall and the bead portion.
