Air plus Water in tires

[Carbon]

Ideally the air in a tire would be dry. What if there is considerable water in there for some reason, such as residual soap solution or other reason. Looking at http://en.wikipedia.org/wiki/Vapour_pressure_of_water I made a PSI vs degrees F chart. My interpretation is that as the temperature rises, until all liquid water is vaporized, the vapor pressure represents the expected partial pressure of the water vapor as a function of temperature in a non-linear way. Once the water is vaporized, the partial pressure of the water vapor will continue to rise with temperature in a way closer to a normal gas.

Any comments on the implications?

Yep, there's a thread on this elsewhere in this section, where I did(and redid when corrected) some calcs on this.

If you did your calculations correct, your partial vapor pressure should equal 14.7 psi at 212 degrees F at sea level.

On a similar topic, I always wondered if there was enough water used during tire installation that the water vapor inside the tire could condense during the winter months.
