Pressure range conflict between tire and rim I just mounted a new Ardnet Race tire that has a side label pressure rating of 35 - 60 psi .  The Stans Arch Ex rim that is mounted to says max pressure is 38 lbs, there is a little range on the sticker depending on the tire size, but this if to the mounted 29" x 2.2" tire.

The suggested ranges says I only have 3 psi to play with, 35-38 psi.  I used to run about 25-28 psi with the former Schwalbe Nobby Nics.  Why is the minimum rated pressure so high on these tires?
The answer from Maxxis support is about what I expected.  I am impressed that they responded and withing about a day.

  The suggested pressure range is 30-60psi for most applications but you may find 
  your particular setup to be different. Rim internal width, rider weight, and 
  riding style determine the correct pressure. I would experiment with different
  pressures to achieve the tire characteristics that work for you.


I rode the tire at about 28 psi this weekend and it felt good.  Old tire still had tread but was hemorrhaging Stan's from the sidewalls and I could not longer keep up with it.
