I cannot get the '08 tire pressure light to go off after adding larger tires. I am running 315 BFG KO AT's. The manual says the pressure sensor also monitors the spare, maybe let air out of spare to match pressure in BFG's? Can the computer be programmed to shut the idoit light off?

 

I think the dealer can reprogram that system to what tire you are running. Not for sure though

 

we can change pressure readings to a degree but what are you running for pressures in the tires currently? do they match the door sticker for tire pressures front and rear. also are you using the light load/heavy load switch to where it would affect . let me know the pressures you are using

 

I am running about 40lbs.
