When storing tires in RFI condition, to what pressure should they be reduced?

• A. 50% of their test pressure.
• B. 50% of their test pressure or 100 psi, whichever is lower.
• C. 100 psi only.
• D. 25% of their test pressure.

Answer: (B)

When storing tires in RFI condition, you lower the inflation pressure to a safe, reduced level to protect the tire while it’s not in use. The correct procedure is to inflate to the lower value between half of the tire’s test pressure and 100 psi. This approach keeps pressure low enough to minimize internal stress and potential heat buildup during storage, while still avoiding excessive deflation that could harm the tire’s structure or seating when it’s later put back into service. If the tire’s test pressure is high, half of that might be above 100 psi, so you cap at 100 psi. If the test pressure is low, half of it will be under 100 psi, and you store at that lower value. Choosing a flat 100 psi for all tires would be too high for tires with low test pressures, and taking only half the test pressure without the cap could leave some tires stored at excessively high pressures. Conversely, 25% would be unnecessarily low and could risk damage during long storage.
