2. Load and Speed: Essential Tire Specifications
The load-carrying capacity of a dump truck tire is directly related to its size, with larger tires generally able to support more weight without strain.
This is especially important for trucks that haul stone, soil, or other heavy materials over long distances, where consistent strength is required.
Tire size also influences speed ratings, which set the safe maximum speed a truck can travel while carrying a load.
For an articulated dump truck, the correct tire size is critical because these trucks often work on uneven ground and must carry heavy loads while still maintaining safe handling.
Selecting a tire that matches both the load and speed needs helps the truck operate smoothly, improves fuel use, and reduces the chance of mechanical problems.
Balancing these factors with the right tire choice keeps operations efficient while protecting the truck from unnecessary wear.
