Abstract

The present invention is directed to a pneumatic tire comprising two spaced inextensible beads; a ground contacting tread portion; a pair of individual sidewalls extending radially inward from the axial outer edges of said tread portion to join the respective beads, the axial outer edges of the tread portion defining a tread width; a supporting carcass for the tread portion and sidewalls; an innerliner disposed radially inward of the carcass; and an electronic sensor mounted in a foamed sensor mount disposed radially inwardly of the innerliner and exposed to the inner cavity of the tire, the foamed sensor mount comprising a foamed rubber composition co-vulcanized and integral with the innerliner, the foamed rubber composition having a density ranging from 0.1 to 1 g/cm³.

Claims

1. A pneumatic tire comprising two spaced inextensible beads;

a ground contacting tread portion;

a pair of individual sidewalls extending radially inward from the axial outer edges of said tread portion to join the respective beads, the axial outer edges of the tread portion defining a tread width;

a supporting carcass for the tread portion and sidewalls;

an innerliner disposed radially inward of the carcass; and

an electronic sensor mounted in a foamed sensor mount disposed radially inwardly of the innerliner and exposed to the inner cavity of the tire, the foamed sensor mount comprising a foamed rubber composition co-vulcanized and integral with the innerliner, the foamed rubber composition having a density ranging from 0.1 to 1 g/cm³.

2. The pneumatic tire of claim 1, wherein the foamed sensor mount has a density ranging from 0.2 to 0.9 g/cm³.

3. The pneumatic tire of claim 1, wherein the foamed sensor mount has a density ranging from 0.2 to 0.8 g/cm³.

4. The pneumatic tire of claim 1, wherein the foamed sensor mount comprises a slit into which the sensor is inserted.

5. The pneumatic tire of claim 1, wherein the foamed sensor mount is substantially centered axially on the axial centerline of the tire.

6. The pneumatic tire of claim 1, wherein the at least one foamed structure has a porosity ranging from about 20 to about 80 percent by volume.

7. The pneumatic tire of claim 1, wherein the at least one foamed structure has a porosity ranging from about 30 to about 70 percent by volume.

8. The pneumatic tire of claim 1, wherein the foamed sensor mount comprises a cavity exposed to an air chamber of the tire, wherein the sensor is mounted in the cavity.

9. The pneumatic tire of claim 1, wherein the foamed sensor comprises one or more mounting pins onto which the sensor is mounted.
