Disclosed herein are polymeric blends suitable for use in non-pneumatic tires, processes for preparing the polymeric blends, and non-pneumatic tires and components thereof incorporating the polymeric blend. The polymeric blends include a thermoplastic polyester elastomer and a crosslinking compound.

Temperature stable polymeric blends for use in non-pneumatic tires

Processes for producing a sealant layer-tire inner liner combination as well as a sealant layer-containing tire and related processes involving the sealant layer-containing tire are disclosed. The sealant layer is adhered to the tire inner liner, has a thickness of 2-8 mm and comprises 100 parts of at least one rubber, 300-500 phr of at least one tackifier, optionally one or more extenders, optionally at least one hydroscopic substance, and a cure package.

Sealant-containing tire and related processes

Disclosed herein are polymeric blends suitable for use in non-pneumatic tires, processes for preparing the polymeric blends, and non-pneumatic tires and components thereof incorporating the polymeric blend. The polymeric blends include a thermoplastic polyester elastomer, a high temperature thermoplastic polymer, a compatibilizer resin, a delayed crosslinking agent, and an activator.

Methods for producing a polymer-containing coating upon a cured tire inner liner using a coating composition of specified composition are provided. Also provided are methods for producing a tire comprising a cured inner liner (with a polymer-containing coating upon its radially inward-facing surface) and at least one component positioned radially inward of the cured inner liner. Tires containing a cured inner liner (with a polymer-containing coating upon its radially inward-facing surface) and at least one component positioned radially inward of the cured inner liner are also disclosed.

Methods for producing polymer-containing coatings upon cured inner liners, methods for producing tires containing such inner liners, and tires containing such inner liners

A tire sealant layer comprising a rubber portion with an upper surface and a lower surface, and a barrier layer upon the lower surface of the rubber portion is disclosed. The rubber portion comprises a mixture of 100 parts of at least one rubber, 90-500 parts of at least one tackifier, optionally one or more extenders, optionally at least one hydroscopic substance, and a cure package. Also disclosed is a process for producing a sealant layer-tire inner liner combination as well as a sealant layer-containing tire and related processes involving the sealant layer-containing tire.

Sealant layer with barrier, tire containing same, and related processes

A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring and a circumferential tread extending about the outer ring. The circumferential tread includes a band layer constructed of a single material and a tread rubber layer directly attached to the band layer.

Tire tread with a band layer

Methods for treating a cured inner liner as well as treated, cured inner liners resulting from such methods are disclosed. Also disclosed are tires containing the treated inner liners. The methods include treatment of the lower surface of inner liner surface with a rubber-containing liquid to produce a rubber-containing film thereupon.

Methods for treating inner liners, inner liners resulting therefrom and tires containing such inner liners

Processes for producing a sealant layer-tire inner liner combination as well as a sealant layer-containing tire and related processes involving the sealant layer-containing tire are disclosed. The sealant layer is adhered to the tire inner liner, has a thickness of 2-8 mm and comprises 100 parts of at least one rubber, 90-500 phr of at least one tackifier, optionally one or more extenders, optionally at least one hydroscopic substance, and a cure package.

This disclosure relates to an approach for monitoring a tire for a puncture based on a change in a voltage established based on a resistance of a material disposed within the tire. In one example, the material is a conductive material layer. In another example, the material is a resistive strip. The systems and methods described herein can monitor for a change in an established voltage over time that is a function of parameters including the resistance of the conductive material layer or the resistive strip, and an applied voltage, to provide an indication of the change in the resistance in the material. The change in resistance of the material can be indicative of the puncture within the tire. The systems and methods described herein can alert a vehicle operator of the puncture within the tire.
