TPMS Light On - 2008 Lexus RX350

The tpms light on my rx350 sometimes stays on while on my drive into work. However, it never is on while on my way back home. What gives?

Your tire pressures are reacting to the temperature outside. When the air in your tires heats up, it expands. You probably just need to fill your tires up a bit more to prevent the sensors from tripping the light.
