    Abstract: Disclosed is an innerliner for pneumatic tires, wherein the innerliner comprises a modified ethylene-vinyl alcohol copolymer (C) obtained by reacting 1-50 parts by weight of an epoxy compound (B) with 100 parts by weight of an ethylene-vinyl alcohol copolymer (A) having an ethylene content of 25-50 mol %. A pneumatic tire with the innerliner can greatly improve the internal pressure retainabilities before and after driving without increasing the weight of the tire.

    Abstract: A pneumatic tire comprising a skin layer which is formed by curing a polyurethane resin composition comprising a compound having active hydrogen atoms and an organic polyisocyanate compound, has an oxygen permeation coefficient at 23° C. under a relative humidity of 60% of 2.0 ml·mm/m2·day·MPa or smaller and comprises 20% by weight or more of a skeleton structure represented by formula (1) is provided. Since the tire has the skin layer formed with the polyurethane resin composition and having an excellent barrier property to gases, the weight of the tire can be decreased, durability can be improved and quiet driving can be achieved while the internal pressure is retained even when the gas filling the tire is the air, and the tire is more economical than tires filled with nitrogen gas. Unlike other tires using other materials having the barrier property to gases to decrease the weight, no adhesives are necessary for disposing the skin layer. Thus, the process can be simplified and the cost can be reduced in the production

    Abstract: It has been unexpectedly found that certain blends of styrene-butadiene rubber and platey filler exhibit both good gas barrier properties and good tensile fatigue properties. These blends accordingly have the requisite characteristics for a tire innerliner material. They offer the advantage of being much less expensive than halobutyl rubbers which can be employed for the same purpose. The present invention more specifically discloses a pneumatic tire having an integral innerliner wherein said innerliner is comprised of a blend of (1) from about 40 phr to about 99 phr of a first styrene-butadiene rubber having a bound styrene content of about 15 percent to about 30 percent, (2) from about 1 phr to about 60 phr of a high styrene content styrene-butadiene rubber having a bound styrene content of about 40 percent to about 60 percent, and (3) from about 40 phr to about 125 phr of platey filler. The subject invention also discloses a pneumatic tire having an integral innerliner wherein said innerliner is comprised of (1) a styrene-butadiene rubber having a bound styrene content of about 15 percent to about 30 percent, and (2) from about 125 phr to about 200 phr of platey filler.

    Abstract: The invention concerns the structures and production of tubeless tire beads the seal of which on the rim and the resistance to degradation of which are increased. The beads, at least the surfaces of which in contact with the rim are formed of protectors (7), are covered, in accordance with the invention, with an air impermeable rubber mix (8) at least in part over the portion of the protector in contact with the rim. Extension of the covering (8) over the surface of the protector which is in contact with the inflation air is desirable.

    Abstract: A tire is made by first fitting a pair of bead rings interconnected by reinforcement over a gas-pervious annular liner to form an annular core assembly and then inflating the core assembly by directly contacting same with a fluid to impart to the core assembly an inwardly open U-shaped section. This U-section core assembly is then spacedly enclosed in a mold which is filled around the U-section core assembly with a hardenable elastomer which is hardened so it bonds to the reinforcement, rings, and liner to form a tire. Finally the liner is deflated and the tire is demolded. The liner has a pair of opposite end edges and is inflated by sequentially clamping each of the edges against a support so as to define between the liner and the support a pressurizable chamber, displacing one of the clamped edges toward the other so as to outwardly bow the liner, and introducing a fluid, typically air, into the chamber. It is also possible to mount the rings in the mold and thereafter introduce the liner into the form for fitting it and the rings together.
