Abstract

A tire, the tread comprising rubber compounds and including a wear limit surface. At least one wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a rubber compound, said region being radially to the outside of a surface radially to the inside of the wear limit surface and the surface radially to the inside of the wear limit surface being, in the unworn state, at a distance from the outer surface of the tread of at most 95% of the thickness of the tread.

Claims

1. A tire comprising at least one carcass reinforcement structure formed from reinforcing elements and anchored on each side of the tire to a bead, the base of which is intended to be mounted on a rim seat, each bead being radially outwardly extended by a sidewall, the sidewalls radially outwardly joining a tread, the tread comprising rubber compounds and including a wear limit surface, wherein at least one wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a rubber compound of the tread, and wherein said region is radially to the outside of a surface radially to the inside of the wear limit surface and wherein the surface radially to the inside of the wear limit surface is, in the unworn state, at a distance from the outer surface of the tread of at most 95% of the thickness of the tread.

2. The tire as claimed in claim 1, wherein said region is radially to the outside of the wear limit surface.

3. The tire as claimed in claim 1, wherein said region is radially to the inside of the wear limit surface.

4. The tire as claimed in claim 1, wherein at least one measurement system is embedded in a region lying in the equatorial plane of the tire.

5. The tire as claimed in claim 1, wherein at least one measurement system is embedded in a region of the axially outer ends of the tread.

6. The tire as claimed in claim 1, including at least two wireless temperature measurement systems based on surface acoustic wave or bulk acoustic wave technology comprising linearly polarized antennas and being embedded in various rubber compound regions of the tire, wherein the polarization directions of the antennas form between them an angle between 30 and 90°

.

7. The use of a tire as described in claim 1, for a two-wheeled motor vehicle such as a motorcycle.

8. The use of a wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology, embedded in a region of a rubber compound of the tread radially to the outside of a surface radially to the inside of the wear limit surface, and the surface radially to the inside of the wear limit surface being, in the unworn state, at a distance from the outer surface of the tread of at most 95% of the thickness of the tread.

9. The use of a temperature measurement system as claimed in claim 8, wherein at least one measurement system is embedded in a region lying in the equatorial plane of the tire.

10. The use of a temperature measurement system as claimed in claim 8, wherein at least one measurement system is embedded in a region of the axially outer ends of the tread.
