Abstract
A tire pressure transmitting apparatus characterized by an elongated antenna having a first end coupled within a wheel and a second end biased towards the wheel such that the antenna is positioned substantially within the circumferential depression in the absence of a counter-biasing force being exerted on it. As the wheel rotates, centrifugal force causes the second end of the antenna to move to a transmitting position within the void of the tire. The antenna is safely biased to a non-transmitting position as the wheel stops rotating.
