Beschreibung
Zusammenfassung:	The present invention provides a method and apparatus to automatically control the speed of a work machine 10 based on ton-miles-per-hour limit of at least one of a plurality of tires 12. A vehicle information system 28 having a processor 32 and a database 34 monitors an actual ton-miles-per-hour calculation of the plurality of tires 12. The vehicle information system 28 functions in combination with an electronic control module 66 of the machine 10 to trigger an automatic speed reduction should the actual ton-miles-per-hour rating exceed a predetermined limit. The speed reduction may be affected by at least one of reducing a throttle setting, changing a transmission gear and automatic application of the machine brakes.
