Definitions for "Undulation"
Keywords:  wavy, rma, vol, sidewall, ply
A wavy appearance or outline; waviness.
A slight indentation or wavy appearance on the sidewall surface of an inflated radial tire. Radial body ply cords run straight across the tire from bead to bead and the joining of the ply material in the sidewall area may sometimes cause this condition. Undulating is a common characteristic of radial tires and will not effect the performance of the tire. Refer to the RMA " Tire Information Service Bulletin", VOL 21, #2. 1999, for more information.

Undulation is a special method of flight employed by many common backyard birds. It is a manner of flying in which a bird flaps several times for momentum, folds its wings and glides downward gracefully, and flaps upward again to repeat the process. While slightly more energy is consumed pulling up and out of the dip, the use of gravity makes up for the loss vastly.
