I decided to further check out the factory installed rim tape on the
new 20 inch wheels. One of my questions was if the rim tape might have
been thicker and that was what made the tires so difficult to get on
and off. I'd never before had such difficulty dismounting a tire as
with the new wheels and the new version of the Schwalbe Green Marathon
tires. On the other hand, it might have been the change in the tires.

The factory installed blue tape might be a little thicker than the
Bucklos that I replaced it with. It was the same width as the 19mm
Bucklos, but it did seem to fit further up the inside of the rim
toward the hooks. It might have been the thickness or maybe because it
was less flexible. After putting on the Bucklos tape and installing
the tire, I tried again to dismount the tire and it was much easier
than before. I don't know if it was because I'd stretched out the bead
or because the Bucklos tape made it easier.

For all practical purposes, tires do not stretch.

A very slight difference in rim liner thickness* has
dramatic effect on the effort required to mount or dismount
a tire, as you found. Any rim tape occluding the actual
seating area of the rim makes tire changing, especially even
seating, extremely difficult.

*Velox cotton rim liners are 0.6mm. Ritchey/Torelli are
0.45mm. That's a very significant difference!

Thanks... that convinced me to change out the other front wheel, and
I'm glad that it did. On this wheel, which I had not checked before,
the factory blue tape did have definite indentations where it had been
pushed down into the nipple holes. I don't know why it was different.
Maybe I stress that side more. At any rate, now all three wheels have
Bucklos tape.

I have no idea what the blue tape material is. It's a continuous loop,
with a glued seam at the valve hole and has a fine texture very much
like the PVC tape I first used on the 26" wheel. That tape a lot of
stretch but the blue tape had almost zero stretch so I had to pry it
off. No label other than IN202005.

I don't know why the new version of 406 Schwalbe Green Marathons are
so hard to put on and take off. I had to use the tire jack to get the
first bead into the wheel. The 599 tire was not a problem.

Indeed despite Silca claims as to why they are using carbon fibre beads as
do some others. But 1st fitting with some tyres can be bit of sweaty
exercise! And become less of cow to fit after that, though in my experience this is the Burly Enduro MTB stuff so 1.5 KG of tyre to wrestle into
position, with reinforced sidewalls which are designed to not fold, road
and utility tyres never had much problem with, including Marathon pluses despite there reputation are comparatively easy in comparison!
