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.
