I have never ran my tires by what the door jam said, well I never looked until I got a Rebel, I looked at everything twice, I always ran my tires as to what it says on the tire itself, tire places always run soft like 10lbs lower and I just assumed they did this so the tire wears out faster... I would hit the air pump and set it to max tire pressure it says on the sidewall of the tire, some said 40lb max so thats where they went, last truck said 50lb so thats where I ran them, have not looked at the goodyears on my rebel yet but my dashboard says 57 on all four so will look when I get home... I was told by someone long ago to run the tire at max pressure to get the wheel to roll smoothly any under inflating causes more drag/friction and creates heat and max will give you the best milage... so I am not sure if thats true or not but I have done this like the last 35 years and never did like it under inflated I can tell if I have a low tire, don't need the tpms to tell me...
