TIRES

Tires should be inspected for proper
inflation, breaks, cuts, and foreign objects
in tread, flat spots and exposed cord.

minimum of 40 psi to a maximum of 62 psi,
depending on the load and runway
conditions. The 12.5 x 4.5-10 ply rated tail
wheel tire and tube pressure should be 55
psi maximum. The wheels and tires are
balanced assemblies.
