I have a new 2016 JC diesel that I picked up on 4/11. It's fantastic. I noticed the tires (265/50r20 Bridgestone Ecopia 422 plus) have lost 6-7 lbs of pressure in just a few weeks. All the tires lost the pressure equally, regardless if they were cold or warm. The fronts came from the factory at 45 lbs and the rear at 50lbs. Issue is the side walls say max pressure is 44lbs and the door sticker says 33 for front and 36 rear. At 33-36 they look super deflated and ride horribly. They ride best at 45-50 lbs but that is over max rating. Does anyone have any advise? I was thinking of keeping them all on 44 but at the same time don't want them wearing out fast due to being over inflated.

My 14' has the Goodyear Fortera's - and I run 35-38 psi. . The only time I've seen them loose that much pressure is transitioning into winter- where they will set of 'low press' indicator @ around 32 psia. If you are not in any wild temp swings in your area it might be worth getting them checked out . (Maybe valve stem guts not tightened in enough?)

Here is Tire Rack link - they list Max pressure at 44 psi- which would be needed if you were 'loaded' ( You should run 35-38 like door says ).
