Tyres, pneumatic. - The air tube is divided by an inner wall h into two cham bers k, l, which are independ e n t l y inflated through separate valves so that one chamber may be employed after the other has been punctured. The chamber l is inflated through a valve passed through the rim a and wall m into the chamber. The chamber k is inflated through a valve p passed through the rim a into a tube o, which traverses the chamber l and opens into the chamber k. The tube o is preferably inclined, and the valve p is secured by screwing together the washer r and flange q. The invention is applicable to both double-tube and other tyres.
