Any suggestions are welcome.

What's your rim strip? I was a long-time Velox user until
just this summer when I switched over to FSA rim strips which
are much thinner. They make more room for the beads of the
tires, rsulting in easier installation and easier seating,
especially with the tighter beads on foldable tires.

Interesting question. The (Ritchey) wheels came with a yellow
plastic rim strip, and a year or so ago I replaced it with basic
Velox. I'm not sure I got the right width, but in any case it
seems to ride just a bit high on the edges. I can see how this
might be a contributor.


I still use 1/2" adhesive tape on a lot of rims. I started
doing it the factory original rim tape caused three flats in
one day during a bike tour, and adhesive tape was the only
thing available. But it worked so well that I've used it many
times since. It is thin, and surprisingly strong.

Interesting thought. I'll file this one away for consideration
in the future.


Mystery solved.

Your tire's inner diameter at the bead is the same size as
your rim at the painted line he

Any occlusion such as a fat rim liner can (and in your case
probably did) wreck that very precise fit.

Sadly, many infamous brands/models of rim have an inadequate
difference between the center well depth and the bead seat
diameter, making tire changes painfully difficult. More,
some have large badly placed nipple holes so close to the
bead seat that covering them is virtually impossible without
covering the tire seat area. With luck, yours is not among them.
