DEFINITION

Classification: 152/450

Pneumatic tire or inner tube:

(under subclass 151) Subject matter wherein a tire casing structure contains a chamber or chambers or a flexible closed annular element carried in said chamber whereby said chamber or annular element is filled with fluid under pressure greater than atmospheric pressure to sustain the tire in inflated shape upon a hub or rim element.

331.1, for multiple chamber tires; subclasses 343.1+ for pneumatic tire casings having sections adapted to enclose an inner tube; subclasses 317, 320, 322, 325, and 327+ for resilient tires having chambers with elastic walls wherein the pressure is atmospheric; subclass 195 for armored inner tubes; and subclasses 510+ for inner tubes.

428, Stock Material or Miscellaneous Articles, appropriate subclass for stock material product in the form of a single or plural layer web or sheet including strips, strands or fibers, and especially

105+, for a composite web or sheet in which constituents or elements (e.g., fibers, strands) in one layer are disposed at an angle to those in another layer; and subclass 114 for such products in which a parallel relationship exists between the constituents of the layers.
