19.50-49/4.0 rim for Mining Dump truck CAT777

The tire sizes for the Caterpillar 777 series of off-highway dump trucks can vary based on the specific model and configuration. As of my last update in September 2021, here are some common tire sizes used for the Caterpillar 777 series:

1. Standard Tire Size for Cat 777D:
- Front Tires: 24.00R35
- Rear Tires: 24.00R35

2.Standard Tire Size for Cat 777F:
- Front Tires: 27.00R49
- Rear Tires: 27.00R49

Please note that these are standard tire sizes, and depending on the options selected by the customer or the region where the dump truck is being used, the tire sizes might vary. Also, tire sizes can change with newer model releases, so it's essential to verify the specific tire sizes for the exact model and production year you are interested in.

If you are considering purchasing or using a specific Cat 777 dump truck, I recommend referring to the official Caterpillar documentation or contacting an authorized Caterpillar dealer to get the most accurate and up-to-date information on the tire sizes for that particular model.
