I just noticed something remarkable.
I did an inspection of the Kishirium SLR, but
since there wasn't really anything worth writing about, I didn't take any photos for an article.
Anyway, regarding Vittoria's new Corsa—
the WO and tubular versions share the same tread pattern.
In the case of WO tires, there's a label on the sidewall casing section,
and the label is in the same phase on both sides (dual labels),
and since the tread pattern has no directional distinction front-to-back,
there's no difference in performance or appearance regardless of which way you mount it.
The label length follows the curve of the tire, but it's roughly 19 cm.
In the case of tubular tires, instead of the casing,
there's a single label at the edge of the tread.
Following the convention of single labels, there are exceptions like the TUFO from the previous article,
but the normal way is to mount them with the label on the right.
So with this WO version of the Corsa, the tread appears to be shared with the tubular,
and at first glance it looks like there's no front-to-back distinction,
but I noticed that there's a "name blank"
about 19 cm long on one side of the tread.
In the case of the tubular, the label is printed here.

In terms of the tread grooves, it's the vertical height where four grooves disappear.
On the opposite side from the name blank, there's
an air pressure specification in a vertical height where two grooves disappear.
Why this is such a big deal is that
from now on, whenever I install this tire, I won't be satisfied unless I position the name blank on the right
and the INFLATE TO on the left.
Even though mounting it the other way won't affect performance,
now that I've found an element that distinguishes left from right—
just like how single-label slick tires are mounted with the label on the right—
I can't ignore it anymore.
Update: I received a comment from someone who has
the amber-colored sidewalls from the initial batch right after release.
Apparently that version doesn't have the name blank.
Since the tire in this article is a later version,
it seems there are some subtle differences between that and the current model.
Thank you for the comment.
It's the same kind of thing as the Shimano 11-speed sprocket spacers (→here).
In the case of spacers, it could actually be used to identify "whether I was the one who installed this sprocket,"
which had practical significance, but
lately people who know about this have been using the same setup,
so it's gotten to the point where "misaligned markings mean I didn't install this sprocket"—that's about all the meaning it has anymore.
