For all 4 tires.


Mine are all down in the 33 range and were in the 38-40...they appear to have all lost air evenly.


I dont' think I've seen a drop off in mpg.

I keep around 38psi cold ( in the early morning) as we have large temp increases by mid day for large chunks of the year. Wear so far seems respectable after 13.5K miles.

I run 45psi cold. My general rule is 10% under Max PSI. I don't like to slow down for the turns, so I want some lateral rigidity and will sacrifice a little ride comfort to achieve that. I have done that for years and never had a tire wear in the center, ie over inflated. The door jam number should be used as a "Do NOT operate below this number" setting. For maximum ride comfort/soft ride use the 39-40 range. It looks like everyone here is in the ballpark.
