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