I did it! Changed to winter air.

If he didn't take his valve stems out and drain them, it's all for naught anyway.How many D&F's will it take to get a BITOG approved 99.9% of the old stuff out?...
One of ChrisFix's best, right along with this one.
Must have been released on an April 1st.
No charge but for members only. Need card to activate.
If you watch to the end, it was in fact April fools lol.
Rookie... Need to hook up a vacuum pump to each tire & then refill them with dry nitrogen!
I've seen plenty of badly corroded aluminum wheels that leak around the rim (worked in a tire shop for years), but I'm wondering what makes one set of wheels corrode and another not? My employer had to replace the factory wheels on our 2010 Tacoma with steelies because they were leaking over a period of a few days and after several clean and reseals that would work for a short period of time it was never fixed. My 2005 Silverado has nearly the same amount of corrosion on the outside of the factory alloy wheels but it has never had an issue with leaking. I top up once a year maybe 10 psi (65psi in the tires heavily loaded with load range D).
Both trucks were used for the same job. Is it just the quality of the alloys or is there another factor?

It's generally road salt in my experience, gets into the bead area.

In Canada they still have it set up so anyone can get nitrogen in their parking lot for free. I’m sure they will add a card reader soon though, as a few weeks ago they added card readers at the entrance in all Canadian locations
Those nitrogen filling stations are great as they eliminate most, if not all of the water as well. I wouldn’t pay extra for a nitrogen fill when I buy tires but I always use their stations for topping up.

Clearcoat on the aluminum failing?
Never knew such a thing existed. Where are these usually located?
Is this a thing at all Costco stores?
TIA
A true OCD BITOG person would rinse and repeat several times to drastically reduce the remaining moisture. And BTW take it up to max tire rating each time except the last.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.
So the obvious question this raises is " is there a gas that will transfer heat better than air and be undetectable by current means when the tire is checked after a race?"
I can see rims being engineered to transfer heat from inside tire air to ambient, and not allowing those red hot brake parts to add heat to the tire or its air.
How much is a small fraction of performance worth and what is the amount of improvement and cost to do it?

The older aluminum alloy's were gravity cast and often came with porosity that couldn't be sealed completely. Not the kind of porosity you could see with naked eye. Nitrogen has larger molecules that don't seep out as easily. We used to produce pressure housings for MBUSA SUV's with air suspension, it was far easier to make a good assembly when the drawings required Nitrogen versus pressurized air for the leak testing.
That's what it looks like on both sets of rims. Just not happening around the bead on the Silverado since it's holding pressure consistently year after year. The current duratracs are at almost 50k miles and 4 years since they were put on. Previous set lasted around that long and also had no leaking issues.
At my local Costco the nitrogen inflation stations are right outside the service area. There are several parking spots reserved for inflation. Currently no membership card is needed at my location, but they just installed new card readers at the entrance, so that may be changing.
I found this chart in Celcius (d'oh). My dry air holds 1.74 g/m^3 of water vapor. The swamp air I evacuated held 18.3 g/m^3, a substantial increase, more than ten-fold!
Is there somewhere that does a UAA? For those of us that prefer long ACI?
As long as you’re not using EAN32-40 to inflate your tires…
