Calculate rolling and parking shoring requirements for pneumatic tires
How it works: This calculator automatically determines if shoring is required and calculates the minimum thickness needed. If the load exceeds standard limits, you will be directed to contact ATTLA for certification.

Shoring Required
No shoring is required. The calculated PIW is within allowable limits for the given tire contact pressure.
⚠️ ATTLA Certification Required
The calculated PSI and PIW values exceed the maximum limits in the PIW chart. Standard shoring calculations cannot be applied for these extreme loads.
Action Required: Contact the Air Transportability Test Loading Activity (ATTLA) for an airlift certification letter before proceeding with this load.
