If on the other hand I inflate to 110 psi when the outside temperature is 30 degrees and head South to warmer temperatures the pressure will go higher than 120?? Seems like the pressure could be too high in some circumstances?? What is too high???
I agree, in extreme circumstances - like going from hot to cold environments (or visa versa) - temp. changes could lead to under and over inflation respectively. When I do this, I check my inflation at regular intervals (after allowing the tires to sit for 5-10 minutes) and generally try to keep the pressure at 5 or 6 psi above the recommended cold inflation pressure. In my mind, with the tires still "warm" there is room for them to expand a little more (say to 10 psi above cold) and room to contract back to the recommended cold psi..
As far as I know, tire manufacturers do not have recommended "running" psi but wonder why
Perhaps the folks at TIRERACK.com could answer this question. They have a chat tool and have been very helpful to me in the past.
Hope this helps a little.
