What is a temperature compensated pressure deviation alert?
Most people know that tires gain pressure as the temperature increases. Since the Road Voice measures both pressure and temperature the system comares the pressure with the temperature to be certain that the tire is operating normally across a range of temperatures. Example: Pressure deviation alert set at 5 psi. Start driving in the morning cold (65 F)at a pressure of 50 psi. As you drive through the desert the tire temperature rises to 145F and the pressure increases to 60 psi. The system compares pressure & temp. and understands this to be normal. If a tire begins to lose air and the pressure drops to 55 psi (5 psi deviation from what the pressure should be) the system will issue an alert. The deviation alert provides very early detection of a problem tire and aids when inflating your tires in Arizona or Alaska.
