Toyota Repair: 2007 Toyota 4 Runner 2 WD, toyota 4 runner, tire pressures

Question
Indicator light that looks like a tire tread with an exclamation mark inside. What is this for ? Vehicle runs fine, brakes okay. Only 55000 miles on vehicle.

Answer
It's the tire pressure warning light, one or more of the tires may be underinflated, check all the tire pressures including the spare, inflate to 34 psi and the light should turn off, if not let me know and also let me know the mileage on the odo and if any tires were removed or replaced.
