On a similar line, when people ask about what PSI to use in their trailer tires, the most common answer seems to be to inflate them to the max PSI on the tire sidewall. I can't recall anyone referring to the sticker on the side of the trailer.
That's because heat/UV/Road Hazard/ect kills trailer tires long before the tread wears out. Keeping them at max cold inflation pressure lets them run a little cooler. They also roll easier, saving some fraction of a mpg. Again, the tire won't last as long as the tread so it's best to get all you can out of it.
