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?

Yes, it is an error
