Harvey and Bob,
It is nice to know that the two of you can "go at it" for a few "rounds" of proper tire technique and
"still respect (each other) in the morning. Really."
And, regardless of which technique(s) one uses, proper inflation counts, too. (But let's not get too "pumped up" about that, shall we?)
Once the ultimate inflation is reached, proper pressure is assured, and the wheel has been returned to its proper position in the frame, don't forget the ultimate rule of tire changing:
Keep the rubber side down." :-)
Jon Spangler who usually uses the Bob Freitas-endorsed technique but who deeply appreciates Harvey Sachs' East Coast methods of tire-marking, tire-centering, and flat- locating in Alameda, CA USA
