The Tire Pressure Riddle

[jar546]

My truck was outside in the driveway all day. Before I drove it, I checked and adjusted the tire pressure and ensured that it was exactly 32psi in all four tires. On my way home late tonight from a hockey game, I saw that my pressures looked like the ones in the photo below. If there are no leaks, the gauges are accurate, and no one touched the tires after me, how can you explain the difference in tire pressures between the driver and passenger side? (EASY)

When you adjusted pressure 2 of the tires had been sitting in the sun and 2 in the shade.

What threw him is that he doesn’t have that problem with his motorcycles.
