Abstract: A non-pneumatic tire includes an annular inner ring, an annular outer ring, and a support structure extending from the annular inner ring to the annular outer ring. The support structure includes a plurality of spokes, webbing, cells, or other open-sided support structure. The tire includes a bump stop. The bump stop includes an inner member radially extending from a radially outer surface of the annular inner ring. The inner member has a radially outer surface facing a radially inner surface of the annular outer ring. The bump stop includes an outer member radially extending from a radially inner surface of the annular outer ring. The outer member has a radially inner surface facing a radially outer surface of the annular inner ring.

Abstract: A protective material comprises in one embodiment a plurality of separate flexible layers, each layer including a plurality of high-strength fibers capable of resisting penetration by a knife or sharp-pointed objects, such as ice picks and hypodermic needles, and a support material, wherein at least part of the fibers are embedded within the support material to restrict relative movement of the fibers therein. The high-strength fibers have a denier of less than or equal to 600.
