Thanks to all I have the 37-597 tires on my
Schwinn now. However I noticed on the rear
wheel, a portion of the tire gets "oblonged"
when properly inflated. I take the tire and
tube off, put the wheel on a truing stand, and
the wheel itself is "pretty true". So this means
it's NOT the wheel. I put back the tube/tire
back on, inflate, and I get the same "non-
roundness" on the tire. I see the tire fluctuate
to 1/4"-3/8" from roundness when observing
it with a guide. It's almost as if the tire "goes
further" in this part of the wheel". This is near
the valve.
To explain it a different way, if one looks at
the wheel and tire as 2 concentric circles, with
the wheel being the inner circle, one would
expect the their two circumferences to be
equidistant throughout, correct? Well in my
case, the outter circle goes "non-uniform"
in one part; hence the circumferences are
non-equidistant in that part.
