<p>A method for monitoring various physical conditions of pneumatic tires (5) and to a tire which includes a memory device (10) mounted on the interior (12) of the tire within the pressurizable cavity and a separate monitoring device (8) mounted on the tire rim (16). The memory device contains a battery, an antenna and stored data pertaining to the tire. The monitoring device uses an active self-powered programmable electronic circuitry which obtains data from the memory device and in addition contains one or more sensors which obtains engineering conditions such as temperature, pressure, tire rotation and/or other operated conditions of the pneumatic tire along with the stored information from the memory device. The memory device can be actuated by externally transmitted radio frequency waves from a remote location or by signals from the monitoring device, and the monitoring device can transmit the information to the remote location by a separate, larger and more powerful battery (42) which is mounted on the tire rim (16) than the battery in the memory device. <IMAGE></p> |
