The present invention is directed to a pneumatic tire comprising one or more indicia formed from an elastomeric coating composition comprising a diene based elastomer and from 1 to 100 parts by weight, per 100 parts by weight of elastomer, of a nanoparticle comprising an inner core of an inorganic magnetic material at least partially covered by an outer layer of silica.

Tire with indicia containing composite magnetic nanoparticles

The present invention relates to a pneumatic tire having a component comprising at least one elastomer containing olefinic unsaturation; and compound of formula I wherein:

Pneumatic tire

The tire has a plurality of radially outer rubber components defining a radially outer surface (S) exposed to fluids having a relative displacement with respect to the rotating tire. At least one radially outer component has projections, the projections being defined by first sides () and second sides () of unequal length. The first sides () have a greater length, delimiting therebetween an angle &#x3b1; ranging from 5&#xb0; to 60&#xb0; and forming at their intersection an apex (P). The projections protrude by a height (h) from the radially outer surface (S) from which said first and second sides originate, the height (h) ranging from 0.2 to 100 micrometers. In more than 75% of the projections, any plane tangent to the first side () of the projection cuts the radially outer surface (S) at an acute angle.

Tire including projections having sides of unequal length and an undercut extending beneath the apex

A degradable sipe blade for forming sipes in a tire tread, where the degradable material may be removed by exposure to water. A tire curing apparatus is also provided having a plurality of degradable sipe blades affixed to the mold surface within the tread pattern. In addition, a cured tire is provided having the degradable sipe blades embedded in the tread elements of the tire tread after removal of the cured tire from a curing mold. Further provided is a method for forming sipes in a tire tread using degradable blading.

Degradable blading for tire curing molds

The present invention relates to a pneumatic tire including at least one component, said at least one component including a rubber composition, said rubber composition including at least one diene based rubber; and at least one metal organic framework material including divalent zinc and a multidentate organic ligand, wherein the at least one metal organic framework material at least partially incorporates at least one guest additive.

The present invention provides a pneumatic tire comprising raised indicia on a sidewall of the tire, the raised indicia comprising a plurality of superposed layers of a curable elastomer composition.

Tire with raised indicia

A rubber composition containing a filler comprising 100 parts by weight of at least one rubber containing olefinic unsaturation, 1 to 250 phr of a filler, and 0.05 to 5.0 phr of zinc oxide particles having a diameter of less than 20 nanometers. This composition can be used to form a component of a tire, especially a tread of a tire.

Rubber composition containing nanoscaled zinc oxide particles

A pneumatic tire having a tread and an outer-facing sidewall area extending from opposing edges of a belt reinforcing structure to corresponding tire beads, the improvement comprising an outer layer of a coating of a fluorinated silane.

A stress sensor includes two capacitor plates held in a spaced-apart relationship by a connector block situated therebetween. The connector block includes a plurality of rods protruding from opposite connector block sides and extending into a respective capacitor plate to attach peripheral portions of each capacitor plate to the connector block. A small air gap is maintained between peripheral portions of the capacitor plates by the inclusion of a spacer member. Terminal end portions of the protruding rods are deformed such as by the application of heat over an outer surface of the capacitor plates to retain the capacitor plates in a fixed mutual relationship. The terminal end portions of the rods further serve to prevent horizontal or vertical slippage between the capacitor plates when the sensor is vulcanized into rubber compounds such as in a tire. Once embedded within the rubber compound, the gap between the capacitor plates varies responsively to stress within the rubber compound whereby varying proportionately the capacitance of the device. A signal is directed into the sensor device and an antenna positioned proximate to the device detects the capacitance value between the capacitor plates. As the capacitance varies proportionately with stress within the material, the antenna detects the changes and transmits data to a remote reader that interprets the data to ascertain measured stress within the rubber compound.

Tire sensor and method of assembly

There is disclosed a rubber composition comprising:

Rubber compositions containing an organically modified ceramic

There is disclosed a pneumatic tire having a rubberized component comprising:

Pneumatic tire having a rubber component containing a dendrimer

Rubber compositions containing preciptated organosilicon particles having a core and a shell

Rubber compositions containing silicon coupled oligomers

This invention relates to preparation of a rubber composition by pre-mixing at least one rubber compounding ingredient with an organic solvent solution of at least one elastomer. The invention also contemplates the use of such rubber composition, or blend of such rubber composition with at least one additional elastomer and/or rubber compounding ingredient, as a component of an article of manufacture. Such article of manufacture may be, for example, a tire. Such article may also be an industrial product such as, for example, a hose or belt such as a conveyor belt or power transmission belt.
