I combined several replies into one post - I know you don't want this thread to expand to the size of those ridiculous threads originated by Henro.

</font><font color="blueclass=small">( What I did was, I bled some air from one of the Cutlass tires into an inverted glass jar and sealed it, then did the same with one of the tires on my 2003 JD. I swear, the air in both jars looks EXACTLY the same. My wife says it looks EXACTLY the same. )</font>
That's because you didn't cool the air - it looks the same at room temperature, but if you put it in the refrigerator sometimes the air will gel, and cause flow problems. May lead to the "Inspector 507 KATHUMP KATHUMP Syndrome". Calcium Chloride used to fill the tires does lower the gel point, preventing the I-507KK Syndrome.

Actually I've heard that with the low dollar, the Chinese are cornering the market on scrap air, and are refining it, sending it back to us as those cans that spray air on computer keyboards. By the way, most of the manufacturing output of air from China is sold at Wal-Mart.

I've always thought it is better to KATHUMP KATHUMP than CHOP CHOP. If you hear CHOP CHOP, it means the air in your tires is low density air (such as helium), causing your tractor to float like a helicoptor.
