About Bontrager tires
The orientation of the text on the tire label—
with the text gravity pointing outward—
is probably unique to this brand alone.
The label would be readable in the correct direction
when it's in the phase where the label contacts the ground,
but even with excellent eyesight, you couldn't read the label text that way.
Bontrager wheels also have their lettering
with text gravity pointing outward, so
as shown in the image above,
Bontrager components are consistent with each other.
For wheels in general, having text gravity pointing outward
isn't particularly unusual.
Incidentally, both the tire and wheel in the image above are tubular.
WO tires also have their text gravity pointing outward in the same way.
The reason for this particular orientation is unclear,
but it seems the tires aren't completely manufactured in-house by Trek.
The OEM manufacturer apparently wouldn't prepare a separate mold
just for Trek
to reverse the tire sidewall markings.
The above images are quotes from past posts.
The Nomu Lab wheel No. 5 I built a while back—
a customer came directly from Yamanashi Prefecture to pick it up
when they had business passing through Osaka.
At that time, I mounted their Michelin tire,
and when I used the standard installation method
of aligning the valve phase to the central area of the label,
with that position at the top of the wheel,
the label markings are readable in the correct direction.
However, there's also a label on the opposite phase where it contacts the ground,
and that too is readable in the correct direction.
In other words, this tire doesn't have text gravity pointing "inward"
but rather in "one consistent direction."
When you position that side's label at the top, it looks like this.
Campagnolo wheels have their lettering and logos
with text gravity in one consistent direction, so
when using this Michelin tire,
normally you'd have:
12 o'clock position
NIꓶƎHƆIW
BORA WTO
6 o'clock position (valve hole on this side for Campagnolo)
CAMPAGNOLO
NIꓶƎHƆIW
instead,
12 o'clock position
MICHELIN
BORA WTO
6 o'clock position
CAMPAGNOLO
MICHELIN
by installing it this way,
the rim and tire markings will be aligned.
The BORA WTO's opposite-side marking is
CAMPAGNOLO
only on the older non-Ultra model,
but on both the older Ultra model and the new model,
the opposite-side marking from the model name is
the Campagnolo logo mark.
