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.
Claims25
A non-pneumatic tire comprising:
- side cavities that are staggered with respect to laterally opposing side cavities;
- and
- laterally extending tread grooves in substantial radial alignment with the cavities, wherein each tread groove comprises a first wall having a first angle of 5° to 65° relative to the radial direction.
A non-pneumatic tire comprising:
- side ribs that are staggered with respect to laterally opposing side ribs;
- and
- laterally extending tread grooves that are substantially radially offset relative to the side ribs, wherein each of the tread grooves has a first wall having an angle of 5° to 65° relative to the radial direction.
A non-pneumatic tire comprising:
- an inner circumferential member;
- an outer circumferential member;
- a central web connecting the inner and outer circumferential members;
- ribs extending from opposing sidewalls to the central web and defining side cavities, wherein ribs on one side of the central web are staggered relative to ribs on an opposite side of the central web;
- and
- laterally extending tread grooves disposed within an outer surface of the outer circumferential member and extending laterally from respective sides of the tire, wherein the tread grooves are substantially offset relative to radially underlying ribs, and wherein each of the tread grooves has a first wall with an angle of 5° to 65° relative to the radial direction.
A non-pneumatic tire comprising:
- side ribs that are staggered with respect to laterally opposing side ribs;
- and
- laterally extending tread grooves that are in substantial radial alignment with the side ribs, wherein each tread groove comprises a first wall having a first angle of 5° to 65° relative to the radial direction.
