摘要： A low tire pressure alarm system for pneumatic tires, wherein a radio transmitter which is adapted to produce an alarm signal of a predetermined frequency upon detection of an abnormal pressure drop is accommodated in a hollow casing for mounting on a wheel cap casing of a vehicle wheel. The alarm signal is transmitted through the hollow casing per se or through a metal coating on the hollow casing where the latter is formed from a non-conductive material. The transmitted signal is received by a receiving set which includes a receiving antenna located on the underside of the vehicle body for shielding the same from spurious or extraneous signals and a radio receiving unit mounted within a luggage compartment of signals. Upon reception of the alarm signal, the radio receiver actuates an alarming device which produces a flashing light or sound to indicate the pressure drop to an operator of the vehicle.

摘要： There is described a pressure-responsive switch device particularly suitable for the detection of a pressure drop in a pneumatic tire on a vehicle wheel, wherein a contact carrying movable rod member is securely urged into a contact closing position by means of a conical compression spring to actuate a warning device whenever the internal pressure of the tire drops below a predetermined level. A permanent magnet may be mounted at the contact point of the switch to impart a quick motion thereto.

摘要： To prevent crack occurrence at groove bottoms on both side areas of foam rubber tread of all-season studless tires, the pneumatic tire having a tread surface portion composed of at least two outer and inner rubber layers is characterized in that the hardness of the inner rubber layer lies from 54 to 80 degrees in Shore hardness and is higher than that of the outer rubber layer, and further the outer rubber layer is made of foam rubber with a foam rate from 5 to 50% with at least 10% volume ratio with respect to tread volume. The outer foam rubber layer serves to improve tire performance on icy and snowy roads in winter, and the inner ordinary rubber layer serves to reduce change in groove width after vulcanization, that is, reduce dynamic strain concentration at lateral grooves and therefore to reduce crack generation at the lateral groove bottoms.
