7.5.1 Tire Damage
For polyurethane foam filled tires, JLG Industries, Inc. recommends that when any of the
following are discovered, measures must be taken to remove the JLG product from
service immediately and arrangements must be made for replacement of the tire or tire
assembly.
• a smooth, even cut through the cord plies which exceeds 3 inches (7.5 cm) in total
length
• any tears or rips (ragged edges) in the cord plies which exceed 1 inch (2.5 cm) in any
direction
• any punctures which exceed 1 inch in diameter
• any damage to the bead area cords of the tire
If a tire is damaged but is within the above noted criteria, the tire must be inspected on
a daily basis to insure the damage has not propagated beyond the allowable criteria.
