Hello and thank you for using JustAnswer.com
What did you set the tire pressures at?
How far have you driven the truck after you set the tire pressures?
hundreds of miles
then you have driven it more than plenty of miles
Since the light has not reset, then you could have a bad sensor
To determine this all the sensors need to be reprogrammed to determine which sensor is the problem
Dealer should only charge you 1/2 hour labor to program them. If one is bad, they should only charge you another 1/2 hour to break down the tire to replace the sensor and balance the one tire. So a total of 1 hour.
Some auto repair shops may have something to clear the tire light, I don't know about reprogramming the sensors.
thank you I will check with some repair shops and get some estimates.
