    Got my Duratracs installed today (285/70-17 -- load range D) and am wondering what psi those of you who have them are running. The installer put 50 psi in and it really rode rough. I dropped them to 45 and will do the "chalk test" once some of the snow is gone. Just wondering.

    Mine are 265/70r17's, load range C. A few weeks ago I did the chalk test, and all tires had 32 psi in them. The rears seemed pretty bang on, but the fronts seemed to need a bit more. I put 34 psi in the fronts today while I was out, and will do the chalk test again when it's not raining.

    Seems to make sense the front would need a bit more b/c of engine weight, etc. For an unloaded truck obviously.
