1. Weight Distribution: Buses and trucks are designed to carry heavy loads, often weighing several tons. To distribute this weight evenly and safely, heavier wheels are necessary to provide better support and stability. The additional weight helps prevent excessive wear on the tires and ensures smooth movement.
2. Load-Bearing Capacity: Heavy vehicles require stronger wheels to handle the increased load and maintain structural integrity. Heavier wheels can withstand the pressure and stresses associated with carrying heavy payloads, reducing the risk of wheel failure or damage.
3. Stability and Traction: Buses and trucks often operate at higher speeds and may encounter uneven road surfaces. Heavier wheels provide greater stability and traction, especially when making turns or navigating curves. The increased weight helps keep the vehicle grounded, reducing the risk of rollovers and skidding.
4. Braking and Stopping Power: Heavy vehicles require more effective braking systems due to their higher mass. Heavier wheels contribute to improved braking performance by providing additional surface area for friction and heat dissipation. This enhances the vehicle's ability to stop safely.
5. Durability and Longevity: Heavier wheels are typically made of more robust materials, such as steel or forged aluminum. These materials offer increased durability and resistance to wear and tear, extending the life of the wheels and reducing the need for frequent replacements.
While heavier wheels may contribute to slightly higher fuel consumption, the primary focus is on ensuring safety, stability, and reliability for heavy vehicles like buses and trucks.
