Abstract
At least one dynamic condition of a pneumatic tire of a vehicle is determined by measuring the rotational angular position of the tire and/or a wheel or wheel carrier the tire is mounted on. The position measurement is preferably combined with transponder measurements of tire pressure and/or temperature, and the measurement information is transmitted from a tire or wheel antenna to a receiver with one or more antennas on the vehicle. The measurements can be combined with a tire pressure regulating device. The rotational angular position is preferably measured by monitoring fluctuations in coupling of RF power between the transmitting and the receiving antennas. In a preferred embodiment, transponders and antennas are disposed in both the tire and the wheel or wheel carrier for the purpose of monitoring the rotational angular position of a tire relative to its wheel or wheel carrier, thereby indicating torsional effects on the tire. Preferably, the tire antenna in the preferred embodiment is mounted inside the tire near the outer circumference of the tire.
