What should the inflation level for dual tires be?

• A. 100 psi
• B. 110 psi
• C. 120 psi
• D. 130 psi

Answer: (C)

The recommended inflation level for dual tires is important for ensuring safety and optimal performance while driving. The correct choice of 120 psi reflects the standard pressure required for maintaining the structural integrity of dual tires, which are commonly used in larger vehicles such as buses and trucks. Proper inflation helps to distribute the load evenly across the tires, reduces the risk of blowouts, and improves fuel efficiency. Maintaining tire pressure at 120 psi is crucial because it ensures that the tires can effectively manage the weight and stress during operation. Under-inflation can lead to excessive tire wear, reduced handling, and increased rolling resistance, while over-inflation can compromise the tire’s contact with the road, leading to a loss of traction and stability. Thus, adhering to the 120 psi standard is essential not only for the longevity of the tires but also for the safety of passengers and the overall functioning of the vehicle.
