1. A device for determining a temperature-corrected tire pressure, comprising:
- an input for selecting a baseline temperature;
a temperature measuring means for determining a second temperature wherein the second temperature is the actual current temperature of said tire;
a pressure measuring means for determining an actual tire pressure at the second temperature;
a processor for calculating a corrected tire pressure corresponding to the baseline temperature based on the actual tire pressure at the second temperature and any difference between the baseline temperature and the second temperature; and
a means for displaying the calculated corrected pressure.

Abstract
Disclosed is a device (10) and method for determining a temperature-corrected tire pressure. A preselected baseline temperature (26) is measured or selected. A second temperature (28) is measured using a temperature probe (22). An actual tire pressure (30) is measured (24). A programmed processor calculates and displays (14) a corrected tire pressure (32) corresponding to the baseline temperature (26) according the ideal gas law.
