Abstract

A method of indicating the degree of ageing experienced by a tire as it is being driven on by a vehicle. The temperature is measured locally at least one point of the tire, the time of exposure to the temperature is measured and these measurements are analyzed using a model of the tire.

Claims

1. A method of indicating the degree of ageing experienced by a tire as it is being driven on by a vehicle, wherein the temperature is measured locally at least one point of the tire, wherein the time of exposure to the said temperature is measured and wherein these measurements are analyzed using a model of the said tire.

2. The method of indicating the degree of ageing experienced by a tire as it is being driven on according to claim 1, wherein the model is a system of graphs and/or a numerical model.

3. The method of indicating the degree of ageing experienced by a tire as it is being driven on according to claim 1, wherein the temperature is measured at the ends of the working plies of the tire.

4. The method of indicating the degree of ageing experienced by a tire as it is being driven on according to claim 1, wherein the measurements are recorded and wherein the degree of aging is the amassed set of measurements that is analyzed.

5. The method of indicating the degree of ageing experienced by a tire as it is being driven on according to claim 1, wherein the measurements are analyzed instantly and wherein information is transmitted to the driver of the vehicle.

6. The method of indicating the degree of ageing experienced by a tire as it is being driven on according to claim 1, wherein at least one temperature sensor, associated with recording and/or communication means, is inserted into the tire.
