I did it! Changed to winter air.

Is there somewhere that does a UAA? For those of us that prefer long ACI?

This really belongs in the humor section.

Thanks for the laugh.

Water does conduct heat better so that's not a bad thing in summer. I would imagine that below freezing it might cause problems as it freezes and take a tire out of balance.

Not a troll post, I swear.

Had a dew point of six degrees F while the ambient air was still above freezing. Perfect time. Put a jack under the affected corners so I wouldn't pinch any sidewalls, pulled valve stems, let all the humid summer air out. Could audibly hear water "spitting" at the valve stem.

This was on tires I mounted this summer. The rubber is soft and pliable-- I use the HF manual changer-- but I trapped some 70 degree dewpoint swamp air in there. It can cause corrosion, it condenses on the tire and rim, and water vapor changes pressure with temperature way more dramatically than air alone.

I must note, that I only got 2/3 of the air, as normal air in a deflated tire is 14.7 PSI anyway just being at sea level.

It goes without saying, that I drained my compressor tank and purged the air line before going to work.

How will I know if I had a benefit? How does anyone at BITOG know their hare-brained routines work? Would still recommend for anyone too cheap to pay for nitrogen.

I used to joke my Porsche dealer recommends to do an air flush every 20k miles since they recommend ridiculous amounts of service at exorbitant prices

Conduct it to where though? The tire needs to shed heat through the rubber and the wheel. That would happen either way.
