    I ride exclusively on Contis. One easy way I found is to look at the tread pattern, it should "point" at the direction of rotation.

    Bingo - The tread lines should point "down" on when the bike is on the ground.

    It never mattered and still does't.

    It doesn't matter. But if you want to follow Conti's recommendation, the Shark Fin goes forward in the direction the shark would swim. Easier than finding the tiny arrow.

    (And did it ever matter which way you mounted them even when the arrow could be found? I could never see anything in the tread that indicated the rotational direction mattered.)
    The only reason these tires had directional arrows was because Conti was sick to death of people asking which way was "right" so they put an arrow on them to shut that down. Jay Strongbow's answer hit's the nail on the head: it never mattered and it still doesn't.

    I guess I find it hard to believe that Conti would put a directional pattern on the tire and include a directional arrow for no reason. Just can't see them being so arbitrary.

    apparently, my front tire was mounted incorrectly according to the directional arrow...

    it currently has 12,500 miles on it and the tread indicators are still plainly visible.

    maybe it matters more on a rear wheel, dunno...

    It's 1000% arbitrary. Tire companies put them there to make you feel good. And guess what.... that tread on your tire... 1000% arbitrary!

    Schwalbe had switched to a slick tread. Then switched back to treads simply because customers are ignorant and they got tired of explaining over and over.

    https://pelotonmagazine.com/uncatego...-one-tubeless/
    The tire has a new tread pattern in place of the previously slick One. As we have heard from many tire manufacturers tread adds zero performance. It does not increase grip, does not channel water, in short it is simply for rider peace of mind. Schwalbe got tired of explaining to pros and amateurs alike that a slick tire created as much, if not more, traction in all situations so they added some purely cosmetic tread.

    Yes you read that correctly. 90%+ of the tyres sold to us cycle tourists have utterly useless and counterproductive tread moulded into them.

    So why do 90% of bike tyres still have tread?
    Marketing... It's a simple answer and the only explanation. 100 years ago bike tyres were slick, but to distinguish between makes manufacturers began adding light tread as their 'signature'. By manipulating the ignorance of the public they could make the buyer thing 'wow! Look at the tread on that tyre must be really grippy!' That this madness extends to even the thinnest of race tyres says a lot...

    It also gives a manufacturer an easy way of making a whole range of tyres all aimed at different markets and price points by the simple expedient of using the same carcass and a bucketful of moulds of different patterns.

    Uh...yes. And while I respect the *opinions* of others, I see nothing factual from the manufacturer that explains why the tires have directional arrows. And not all makers have arrows, in fact, very few.

    Yes, the tread isn't really needed, but it is there, and directional. I'd love to hear from Conti as to why they include the directional arrows.

    Not the first time this has been discussed, either. Conti says aerodynamics are better (not by much...) when rotating in the "right" direction.

    Yes, where this has been discussed before, with an explanation from Conti regarding the directional nature of the tires.

    The marketing "feel good" answer? It's there so your tires go the right direction.

    The real answer (that they're not likely to admit)? It is simply for rider peace of mind.

    Think about it... if tread "adds zero performance", then putting the tread "backwards" subtracts zero performance.

    A zero sum game, as it were.
