I'm still trying to figure how a sensor on the stem of the tire can monitor the internal temperature of a tire. Unless this is a technology I'm not familiar with there's no way to ACCURATELY sense the temperature since the valve stem is spinning the airstream the sensed value is cooler than the internal temperature. Also, the ambient temperature of the air, be it Summer's 115 degree or Winter's 45 degree is going to impact the valve stem temperature, same thing the Doran engineers I talked to questioned about the PressurePro TPM system's claims.
