1. A method for monitoring the operational reliability of a vehicle tire, including:
- embedding at least one temperature sensor in a shoulder region of the vehicle tire, transmitting an output signal of said at least one temperature sensor to an evaluation unit, and evaluating said output signal in said evaluation unit with regard to at least one of magnitude and trend with respect to time, wherein said output signal, or a function that is dependent upon said output signal, is integrated in said evaluation unit, wherein a value of an integral thereof is stored and indicates a wear signal if the value of said integral exceeds a predetermined threshold value.

Abstract
A vehicle tire is provided that contains at least one temperature sensor embedded in the tire in a critical location, and a transmission unit for transferring the output signal of the temperature sensor to a location externally of the vehicle tire. A method is also provided for precisely measuring the temperature of a vehicle tire with such a temperature sensor. A method is also provided for monitoring the operation of the vehicle tire.

10. A method of introducing a temperature sensor into a vehicle tire, including the steps of:
-
forming a channel in rubber of a tire, wherein said channel proceeds from a first location on a surface of said tire, through said tire rubber to a measurement location in a vicinity of at least one of a belt of said tire and a carcass of said tire in a region of a tire shoulder, and to a second location on a surface of said tire that is remote from said first location, introducing a tube into said channel, introducing a temperature sensor into said tube such that said temperature sensor is disposed in the region of said measurement location, removing said tube from said channel while holding said temperature sensor in place, and closing off said channel with said temperature sensor therein. - View Dependent Claims (11)

12. A method comprising:
-
measuring the temperature of at least one vehicle tire over time using at least one temperature sensor embedded in a shoulder region of the at least one vehicle tire, wherein a temperature signal representative of the measured temperature is generated by the at least one temperature sensor, transmitting the temperature signal to an evaluation unit, integrating the temperature signal with respect to time, thereby generating an integral value, storing the integral value, determining whether the stored integral value exceeds a predetermined threshold value, and indicating a warning when the stored integral value exceeds the predetermined threshold value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
