Pirelli announced last month their X-Pressure AcousticBlue tire pressure monitoring system. In addition to the new X-Pressure Optic system (which indicates problems by the color of its valve stem), the AcousticBlue can send warnings to your Bluetooth mobile phone that are presumably helpful. A Bluetooth warning is infinitely better than the $14 “talking” tire pressure gauge my grandfather gave me last Christmas.
