SUMMARY
The discussion focuses on calculating the change in tire pressure after driving, specifically from an initial temperature of 16.0 C (289 K) and pressure of 20.0 psi to a final temperature of 38.0 C (311 K). The key formula used is the proportional relationship pf/pi = Tf/Ti, where pf is the final pressure and pi is the initial pressure. The pressure constant R is noted as 8.31, and the initial pressure is given as 1.36 atmospheres. The volume of the tire is assumed constant, and no additional air is added during the drive.
