Yeah but the "cold" pressure changes with the ambient outside temperature. Plus if the car is parked so one side is exposed to the sun, you have to compensate for that.
Right now, my cold pressure varies between 28 and 30. After driving awhile they all equal out to 33. You can really tell if you have it too low by how it handles the ruts.....yikes!

A few years ago I had a HVAC guy tell me that for every 7*'s there will be a 1 pound pressure change. Don't know if it's true but it did make sense to me. Then again I'm 61 so don't quote me, I lived through the 60's and 70's and may have some dead brain cells
