SECTION 5 - SPECIFICATIONS

TIRE LOAD AND INFLATION TABLES

Use the following chart and guidelines to determine the proper inflation pressure for tires on a given axle. Divide the axle weight by the number of tires on an axle to determine the load to be carried by each tire. The values shown in the shaded areas are for bias ply tires.
