Some MTB and gravel treads are directional so if the snow is crisp enough
to work out the tire pattern that is one potential clue.

As I understand it, the treads should be pointing opposite each other

The Front tyres on my MTB and Gravel bikes are directional and only one
way, the rears are unidirectional.
The tread on the Big Apples are apparently directional but are cosmetic!
Does I guess show wear rate and how old tyre is, they don’t tend to wear out but get cut up and become puncture prone eventually.

I read an article in Velo news a very long time ago when mountain biking
was first becoming big on MTB tread design. The article basically said
the only things that matter with MTB tire design are the size and
spacing of the lugs. Direction of the tread doesn't really matter. One specific thing I remember from the article was an engineer they
interviewed from Specialized who said tread pattern is overrated at
best. The quote I remember was "we could make a tire that leaves your
name in the tire print and it would be as good as any tire on the market".
The only caveat there is that was when tires were rarely outside 1.95 to 2.35". Bikes back then weren't being built to handle any more than that. These days, I've noticed more of a difference in width than anything,
which is why I'm running 2.8R/3.0F on my FS.

There are - or at least, were - directional arrows on some motorcycle
tires. IIRC, on Dunlop K81s that I used on a previous motorcycle.
Tread was symmetrical. I assume there's something relevant in the
internal construction.

As I understand it, the treads should be pointing opposite each other
on the front vs the back. Even road tires have directional tread, but
I once read a blurb from Schwhalbe where they admitted that the
direction of the tread on their road tires was only for looks.

I read an article in Velo news a very long time ago when mountain biking
was first becoming big on MTB tread design. The article basically said
the only things that matter with MTB tire design are the size and
spacing of the lugs. Direction of the tread doesn't really matter. One
specific thing I remember from the article was an engineer they
interviewed from Specialized who said tread pattern is overrated at
best. The quote I remember was "we could make a tire that leaves your
name in the tire print and it would be as good as any tire on the market".
I’d add also add the caveat that Specialized while they do have one of the iconic MTB models, there tyres particularly MTB have never got beyond Meh, not bad but not perceived as kinda okay and tend to review as such.
Unlike in the Gravel space where the Pathfinder gets some love as the
racers like semi slicks.
I’d also note that in the DH space trimming knobs down and/or adding cuts, particularly as if one is sponsored maybe a gap in your sponsors line up.
I run 2.4/2.35 which is about right but tyres on the burly end of trail so Magic Mary up front which lives up to its name in that it manages to grip from slop to the hard pack only downside being not the lightest of fastest rolling, it’s shoulders are definitely shaped as to why and would it make a difference?
The only caveat there is that was when tires were rarely outside 1.95 to
2.35". Bikes back then weren't being built to handle any more than that.
These days, I've noticed more of a difference in width than anything,
which is why I'm running 2.8R/3.0F on my FS.
Even just the front tyre makes a difference to the bike handling as has a slightly more square shape than the Hans which I had on front/rear before, which is noticeable on tarmac though isn’t a thing once off road, though do notice the increased grip and mud clearance, it’s about the same on harder surfaces.
It’s not quite a full race spike but it’s very close but unlike those or other dedicated mud tyres they aren’t lethal on wet roots and what not.
It’s broadly similar in construction to others in the Schwalbe lineup ie it’s the knobs that seem to make the difference, in its ability to grip in loose and wet conditions.

Why are there direction arrows on fully smooth road tires?
I know they're there on my Schwalbe HS20s, but I pay no attention to
them.
