ABSTRACT:
A non-pneumatic tire comprising side cavities that are staggered with respect to laterally opposing side cavities, and laterally extending tread grooves that are either in substantial radial alignment with the cavities or substantially offset relative to the cavities. The tread grooves have at least one wall that is angled with respect to the radial direction, i.e., the direction relative to the tire's axis of rotation. The wall may be an open angle having an angle of 5° to 65° relative to the radial direction. Also provided are processes for making such tires and to off-the-road (OTR) vehicles employing such tires.
