Tires
Note (1)
Productive capabilities of the 770G truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.
Note (2)
Caterpillar recommends the customer evaluates all job conditions and consults the tire manufacturer for proper tire selection.
