Review Schwalbe-Durano-2015
No significant tread on these road tyres so mounting direction is irrelevant.

I can often not tell whether rr is joking or not, but for the avoidance of doubt, the contribution above has no validity.

I think the concern is that mounting the tyre the wrong way will cause your gears to operate backwards, and your brakes to release when you pull the lever. Such reckless behaviour can have serious consequences.

I split my rear Durano Raceguard 700x32 on some glass a wee while back and although the split has only increased by 1mm approximately it has now started to bulge slightly nearest the wall. The boot I put in has also allowed the tyre to have a slightly different shape and when you ride on smooth tarmac, it feels like there is a flint or something stuck on the tyre. On the turbo it is audible. Annoying in fact. Taking advice from the wise and careful types on here I decided to get another.
I ordered another tyre from Tredz and it arrived today. WITH the rotation arrow at no extra cost. Bargain.

It’s explained here ( regarding the dependency of direction / pattern on aero)
And here regarding grip / braking performance.

First of all, welcome back from your sabbatical, @Racing roadkill
Recalling that tread on cycle tyres offers no advantage regarding water dispersal:
1) He suggests that the tread (if orientated the 'correct' way') will afford "better water evacuation in the curves" (what does that mean? round bends?)
2) Since the tyres are both going round the same way (assumes bike is going forward) if there was any merit in this 'water evacuation', why would you want the one tyre to go on one way and the other to go on the other way? Agree that the critical function of the rear is to effect drive and that of the front to allow braking, but these sipes (as in the diagrams) will have no relevant beneficial effect.
Mr Cotty, the 'Mavic Community Manager' (lucky guy) might wish to review this (his own company's) Schwalbe advice: https://www.schwalbe.com/gb/profil.html
"In the case of a road tyre the rolling direction is mainly important for aesthetic considerations. Tires(sic) marked with arrows simply look more dynamic." (my emboldening)
The link you offered makes no mention of the importance or not of the direction that the tyre is fitted.
I have to observe that Mr Cotty's advice/opinion is flawed with logical anomalies.

I wouldn't get caught up too much about all this drivel with tyre direction. Honestly it's boring and while i'm all for putting tyres on the 'arrow' way, there really are more important things in the world.
. . . Like did you stop & think whether you put your innertubes in the right way round?

Which is why some mountain bikers run their tyres 'opposed'.
No idea if doing so makes any difference, but I suppose it could in proper mud.

Well if you want to argue with
“Jean-Paul Ballard is an aerodynamicist, engineer and co-founder of Swiss Side, who has over 14 years’ experience as a lead engineer in Formula One teams”
about it, I’m sure he’s bothered.

And we need to consider the direction of the mud. Ascending, descending and lateral cambers to consider. Soil engineers would be better placed to comment.
