mowdoc, good tip on the 2:00 or 11:00. Tried it and it does make it easy to reach the valve stem.
Vicr, thanks for confirming the metal stems on all 6 tires, don't know why they told us they were rubber. Actually, I have a idea why...
!
Our new air compressor came yesterday and the 45 degree extended chuck fits on the inner value stem without a problem, so we will not be looking at extenders.
Thanks so much for all your input.
