Method of determining potential cause of tire failure by measuring the tire temperature achieved during operating conditions
First Claim
1. A pneumatic tire for a vehicle having an indicator that allows an investigator to identify the temperature experienced by the tire as a potential cause of a tire failure;
- the tire comprising;
a body having an inner surface; and
an indicator carried by the body;
the indicator being a non-reversible temperature-indicating label having a first temperature-indicating area adapted to provide an indication when the area is exposed to a first minimum temperature and a second temperature-indicating area adapted to provide an indication when the area is exposed to a second minimum temperature.

Abstract
The invention provides a tire and a method for analyzing the temperature exposure to the tire. The tire and the method allow an investigator to determine the maximum temperature the tire experienced during its operation. This information offers a potential cause for the tire failure by allowing the investigator to determine a maximum temperature experienced by an area of the tire by reviewing a non-reversible, temperature-indicating label positioned at a location in the tire. The information may be used to identify a potential cause of a tire failure after the failure has occurred. The information may also be used to identify a damaged tire before the tire fails.

7. In combination, a pneumatic tire, a tire rim, a tire-monitoring device, and an indicator;
-
the pneumatic tire having a body having an inner surface;
the tire being mounted to the tire rim to define a chamber;
the tire-monitoring device being carried by one of the tire and tire rim;
an indicator carried by one of the tire;

17. A method of analyzing a pneumatic tire to determine if the tire has been harmed due to exposure to excessive heat;
- the method comprising the steps of;
(a) applying a non-reversible, temperature-indicating label to the pneumatic tire before the tire is placed into normal use;
(b) using the tire with the label until the tire fails;
(c) after the tire has failed, reading the label to determine the temperature of at least one component of the tire; and
(d) determining if the temperature of the component could have caused the tire to fail. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
