Anyone else had trouble putting air in your tires?
Had a nail in my tire, plugged it, and took the wheel to a local gas station to fill it up. But the air chuck didn't fit the valve stem on my wheel -- seemed as if the stem is smaller than normal. I've filled up tires on other cars at this station. But didn't work on the 991, which has factory stems/TPMS. Seems silly -- what am I doing wrong here?
And yes, a 991 wheel will fit in an early 911...

sounds like it wasnt pushing the valve stem core in enough... stem is universal and all the same.. but these TPMS cars sometimes i feel like the core is a little deeper

I think I had a similar issue and the realized that the rubber gasket from the valve stem cap had stayed on the valve stem side and was keeping the pump chuck from seating correctly.

I have a valve on one of mine that does not like certain chucks. I have a pull down air hose from my garage ceiling....and that will fill 3 of my 4 tires just fine...but swings and misses on tire number 4...just sits there and does nothing. I have to get out this old portable Black and Decker inflator to be used on that tire. Very odd.

At my hanger I have an N2 system for use mainly on the aircaft but does also work well on auto tires. It is a screw on chuck, with the addition of a system that pushes the valve core open only when you want to add N2, or air. It is the screw **** at the top that does that. This way you get zero pressure loss when undoing the chuck. It is a bit fussy to use and I have just regular 'air chucks' also. It main purpose in life is filling high pressure oleo struts, but as noted it also works on low pressure auto tires. The picture below is not the actual one I have, I just grabbed it off the web. I too have found variations in Schrader Valve stems and chucks. Some not working in various combinations. But the screw on system always works. Mine is an actual Schrader part, I think it cost about $30, it is easy attach to end of any hose system using off the shelf screw fittings.

^^ It's always nice to see a guy build his mechanical skill set! Kudos to you! And they say 991 drivers are a bunch of know-nothings who hire everything done. psshh... You attempted something difficult, ran into some problems, went to the internet for help, and stayed after it till you solved it! A lot of guys would have booked a trip to the dealer.
