Tire pressure recommendation discrepancy

[Shaggy G]

I have a Air Touring with 245/45 R19 wheels. The sticker on the door frame specifies 49 psi for both front and rear tires.

The new software update recommends 42 psi all around. The software knows what tires are on the car.

What is the correct number? Thanks

49 psi

Thanks Duncan. I guess the software is in error?

 

[Duncan C]

Yes, it is an error

Thanks! I have the same issue. I had 44 PSI in all tires but still giving me warning sign. I think I need to fill up to 49 to get rid of that. I have 19-inch wheels as well.

Did you check to see if the car has the correct tire size entered into the system? It sounds like the tire pressures that would go along with lower profile tires.
