BIAS-PLY TIRES. Bias-ply tires (fig. 3-16) are
constructed of rayon, nylon, or polyester casing plies in
a crisscross pattern wrapped around steel bead wires.
These bead wires prevent the tire from opening up and
separating from the rim at high speeds. The casing plies
give the tire its shape.
Uneven tire wear is often caused by mechanical
irregularities on your piece of equipment. During your
prestart and post operations, inspect your tires for wear,
as shown in figure 3-17. These conditions can be caused
