Productive capabilities of the 777E truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.
