4. 20 – The Wheel Diameter

- Aluminum Lightweight yet strong, aluminum is favored for engine blocks and cylinder heads. Its low density contributes to overall vehicle weight reduction, enhancing fuel efficiency. Additionally, aluminum has excellent thermal conductivity, which helps in dissipating heat effectively.

However, the transition to hybrid excavators is not without its challenges. One of the primary obstacles is the higher initial cost of hybrid machinery compared to traditional excavators. Although the long-term savings on fuel and maintenance can offset this investment, many companies are still hesitant to make the switch. Moreover, the availability of charging infrastructure and the need for trained personnel to operate and maintain hybrid systems are additional concerns that need to be addressed as the industry moves forward.

The heavy-duty truck sector in China has witnessed remarkable growth and transformation in recent years. As the backbone of the country's logistics and transportation industry, these vehicles are essential for moving goods across vast distances. With the rapid development of China's economy, the demand for heavy-duty trucks has surged, prompting manufacturers to innovate and improve their offerings.

- Fuel Efficiency Given the rising costs of fuel, it's wise to consider the fuel efficiency of the coach. More modern vehicles often come with advanced engines designed for better fuel economy.

3. Fitment Not all vehicles are designed to accommodate larger tires. Depending on the vehicle make and model, lifting the suspension or making modifications to the fenders may be necessary to fit 33x12.50R22 tires without rubbing.
