Red Seal Transport Trailer Technician Practice Exam

What is the standard tire pressure range for most transport trailer tires?

1. 50 - 70 psi

2. 80 - 110 psi

3. 90 - 120 psi

4. 100 - 130 psi

The correct answer is: 80 - 110 psi

The standard tire pressure range for most transport trailer tires is typically between 80 and 110 psi. This range is essential for ensuring optimal performance of the tires under load, providing good traction, minimizing tire wear, and promoting fuel efficiency. It is important for trailer operators to maintain the correct tire pressure within this range, as both under-inflation and over-inflation can lead to problems such as poor handling, reduced safety, and increased risk of tire failure. While other ranges may be found for specific types of tires or applications, the general standard for most transport trailer applications aligns with the 80 to 110 psi specification. This range is recommended by tire manufacturers and industry standards to ensure safe operations, long-term durability of the tires, and vehicle performance under various loading conditions.
