Got an 05 SR5 Double Cab Tundra the other day and is an awsome truck. Most impressed so far with gas mileage. Drove about 180 miles, refilled, and averaged around 20mpg. EPA 14/17 which was what I for with my 98 z71. One problem though. Tire pressure light has started flashing. Have read a few posts on this. Is this a very common issue with the Tundra? Thx!
