Calculate tire contact pressure (PSI) and pounds per inch width (PIW) for pneumatic tires
How to use: Enter tire contact measurements and wheel weight to calculate PSI and PIW. Results will show if values are within aircraft floor loading limits (using maximum in-flight PIW only).
Note: This calculator is for pneumatic tires with width ≥ 4 inches. For tires with width less than 4 inches, use the Steel and Hard Rubber Wheel Calculator.
