In tire testing conducted in the cage, what is the purpose of pressurizing the tires?

• A. Check tread depth
• B. Seat the tire beads against the rim flanges
• C. Balance wheel
• D. Measure rim diameter

Answer: (B)

Pressurizing the tires in the cage serves to seat the beads against the rim flanges. The bead is the edge of the tire that grips the wheel, and as the tire is inflated, the bead is pushed outward and snaps into place against the rim’s bead seating area. This creates a proper seal and a secure, concentric fit, which is essential for the tire to stay on the rim during testing and to provide accurate results in subsequent checks. Without proper bead seating, you could get leaks, beads that aren’t fully engaged, or instability during tests. This step isn’t about checking tread depth, wheel balancing, or measuring rim diameter, which require different procedures or tools.
