This is the only part of the truck that disappoints me-- the info screen. Seems like they left a lot on the table. Tire pressure, boost should have been included at a minimum.
Without a doubt that feature should exist. Our '05 Tahoe, '07 Denali, '09 G8 GT had this feature, being able to read exact tire pressure from any of the four tires.
The government requirement (TREAD act) is for manufacturers to put an idiot light mandate by September 1, 2007 all vehicles manufactured must have tire pressure warning indication. Level that the warning indicator will illuminate on the dashboard varies from 25% below recommended pressure on direct TPMS systems to 30% below for indirect (ABS involved and calculated) TPMS systems.
Ford did near the absolute minimum on this system in our trucks. The required warning indicator the only additional feature is the IP display of "low tire pressure".
Just today while driving down the highway in a heavy thunderstorm I got the warning indicator and the additional message on the IP "low tire pressure". While driving I used the mirrors to visually check the rear tires, they appeared fine. The front wasn't pulling and gave no indication through the wheel there was an issue. Didn't want to risk issue in pulling off a busy highway in a down pour to find out what I suspected was a malfunction. When I got home, inspected and verified tire pressure, no issues found.
Now what would cause the low tire pressure warning without the condition existing? Something is malfunctioning.
