I would agree with most of this post. The door sticker is meant for OEM tires. Changing to a different tire most certainly will change optimal tire pressures, unless you stick with only OEM tires. Many of us swap to a different tire based on our needs/wants, and then the recommended pressures on the door sticker become moot.The door sticker is the federally mandated information that is supplied by the manufacturer and is specific to your vehicle, hence the Vin # on the sticker. This info is based on the vehicle specs such as gvwr and suspension specs. Changing tires to another brand does not change the vehicle specs such as weight. The sticker also states "cold " inflation specs so no need to calculate "hot" tire pressures.
Toyo recommended 50 psi cold for my LT E open country at3’s…seems good so far. Did the chalk on the rears and was even except a hair of the end of the tread. BF good rich recommended 47 for my ko2’s in a LTEI came across the chalk test that is working for my Toyo LT tires. Over inflate your tires by 10-15 lbs or so. Go to an empty parking-lot and take a piece of chalk and run it across the full-width of tire. Drive in a straight line for at least two tire rotations. Look for chalk to be evenly removed across the tread. If there is chalk removed from the center of the tire and not the edges, there is too much pressure. Reduce the pressure by 2-3 pounds, drive in a straight line for another two tire rotations. Keep doing it until the chalk has been removed evenly across the tread. My pressure ended up being 50 psi, the tires have been rotated 3 times and there is even wear. And yes with LT tires and at that pressure the ride is a little bit rougher but the tires are on the spendy side and I am getting great life out of the tires.
