摘要 |
A dual-chamber pneumatic tire having two separate concentric annular air chambers. The outermost air chamber, disposed behind the tire tread normally in contact with the ground, is toroidal and substantially elliptical in cross-section, and is inflated at a higher pressure than the innermost chamber disposed in the remaining volume of the tire. The two chambers are separated by a wall or diaphragm which is integrally attached to the tire casing interior walls or which is, alternatively, made removable. The low pressure innermost chamber is inflated by means of a conventional air valve, while the outermost chamber is inflated by means of an additional air valve connected to the wall or diaphragm by means of a flexible hose. The structure of the invention is particularly adapted to tubeless tires.
