Tire management system and method

A system for managing a plurality of machines, comprising:

• a plurality of machines, each having a control module;
• a tire sensor associated with a tire on each of the plurality of machines, the tire sensor measuring tire data including at least one of tire temperature and tire pressure;
• a worksite controller in communication with each control module, the worksite controller configured to:
• generate a travel path for the plurality of machines between a first location and a second location;
• and
• selectively communicate the travel path to each of the control modules;
• a central processor in communication with the worksite controller, the central processor being configured to:
• receive the tire data and compare the tire temperature to a map of tire load versus tire temperature and ambient temperature to determine a tire load for each tire;
• compare the tire load for each tire against a tire rating;
• and
• determine whether the tire rating will be exceeded by the tire load on a current assignment,
• wherein the worksite controller is configured to generate a new travel path for at least one of the plurality of machines such that the tire rating will not be exceeded by the tire load.

A method of managing a plurality of machines, comprising:

• receiving tire data associated with a tire sensor on a machine over a network, the tire sensor being associated with a tire on the machine and the tire data including at least one of tire temperature and tire pressure;
• determining a tire load for the tire using one of:
• a map relating tire load to the tire temperature and ambient temperature, or
• a map relating tire load to the tire pressure and ambient pressure,
• wherein tire load is a ton kilometer per hour (TKPH) value;
• comparing the tire load for the tire against a tire rating for the tire;
• and
• determining whether the tire rating will be exceeded by the tire load on a current assignment;
• and
• altering the current assignment of the machine in response to determining that the tire rating will be exceeded by the tire load.
