Method of determining a tire performance characteristic of a tire

A method of determining a tire performance characteristic of a tire, the method comprising:

• querying, using a processing system, a memory as to a presence of a first set of values indicative of a tire parameter of a tire in the memory;
• determining, using the processing system, that the first set of values is insufficient to determine the tire performance characteristic of the tire;
• and
• performing steps, using the processing system, comprising one or more of:
• providing an indication that a second set of values indicative of the tire parameter is required to determine the tire performance characteristic of the tire;
• or
• retrieving, from the memory, a performance coefficient of the tire corresponding to performance of the tire associated with the first set of values, and determining, based on the performance coefficient, the tire performance characteristic of the tire,
• wherein the determination that the first set of values is insufficient to determine the tire performance characteristic of the tire is indicative of one or more of introduction of a new tire monitoring device associated with the tire, the tire comprising a new tire, and association of the tire with a new wheel.

A tire performance monitoring system comprising:

• a memory configured to store a first set of values indicative of a tire parameter of a tire;
• and
• a processing system configured to:
• query, the memory as to a presence of the first set of values;
• determine that the first set of values is insufficient to determine a tire performance characteristic of the tire;
• and
• perform steps comprising one or more of:
• providing an indication that a second set of values indicative of the tire parameter is required to determine the tire performance characteristic of the tire;
• or
• retrieving, from the memory, a performance coefficient of the tire corresponding to performance of the tire associated with the first set of values, and determining, based on the performance coefficient, the tire performance characteristic of the tire,
• a tire monitoring device configured to obtain a plurality of measured values of the tire parameter, the tire monitoring device comprising a local memory configured to store the plurality of measured values;
• and
• a remote device configured to retrieve the plurality of measured values from the local memory, and transmit, based on the plurality of measured values, the second set of values to the memory,
• wherein the remote device is configured to provide, based on the indication that the second set of values indicative of the tire parameter is required to determine the tire performance characteristic of the tire, a notification to a user of the remote device that the second set of values is required.
