EnTire Solutions LLC will supply direct tire pressure monitoring systems (TPMS) for the 2007 Hyundai Tiburon, Kia Amanti and Kia Spectra vehicles. It already supplies TPMS for the Hyundai Tucson and Kia Sportage, as well as for vehicles from Honda, Toyota and Fiat.

EnTire Solutions' direct TPM systems employ a battery-powered pressure sensor mounted on the valve stem inside the wheel. The sensor communicates tire pressure and temperature information to a vehicle-mounted receiver via a radio signal. The company is a joint venture between Michelin and TRW Automotive.
