Red Seal Transport Trailer Technician Practice Exam

How can air suspension enhance the performance of trailers?

1. By adding additional weight to the trailer

2. By providing a stiffer ride

3. By providing a smoother ride and improving tire wear

4. By reducing the number of tires needed

The correct answer is: By providing a smoother ride and improving tire wear

Air suspension enhances the performance of trailers primarily by providing a smoother ride and improving tire wear. The key advantage of air suspension systems is their ability to adjust the ride height and cushion the load, which mitigates the impact of road imperfections. This results in less jarring movement for the trailer and its cargo, leading to improved handling and stability. The adjustable nature of air suspension also helps in maintaining consistent contact between the tires and the road surface. This consistent contact is crucial for even tire wear, which extends the life of the tires and improves safety by maximizing traction. Furthermore, the system can respond to varying loads, ensuring that the trailer maintains an optimal ride height and comfort across diverse conditions. Additional benefits include better weight distribution and reduced stress on the trailer frame and its components, giving it a longer lifespan and preventing structural issues. The smooth operation of air suspension systems contributes significantly to the overall performance and reliability of trailers in transport applications.
