    Have just finished putting on a new back tire when I see that the tire has a recommended rotation.

    The tire is rotating the other way.
    Is this a big deal, should I ignore it or start again and install again.

    If there is a tread pattern, I would switch it around, but that's me. Remember, the more tire changes you do the easier they become. That would probably take me a total of 4 minutes, including pumping it.

    Flip it. A couple of minutes. It may not make a big difference, but I really doubt if it is going to perform any better (especially in hard braking) with the rotation reversed, so why risk it.

    Definately had to be flipped for the tread to work properly.

    Thanks for the replies.

    For "some" off road tyres, the rotation is reversed for the front tyre, this gives better grip for braking.

    it can matter : either
    A) if front wheel just turn it around in the forrk - may need to move magnet .
    B) if rear wheel , get your hands dirty , again .

    sorry but fabricators don´t do this sort of thing without good reason ( well that´s the theory anyway ) so do follow their advice where possible and where you don´t know better than they do - which can happen .

    If it's a road tire, I'd just leave it. A recommended rotation for a road tire tread is just a bunch of hogwash. In practice it makes zero difference. In fact the minimal tread pattern on a road tire is just there to give the consumer the impression that they're going to get better traction and in reality it makes no differnence whatsoever. A smooth tire gets the best traction on pavement.

    And that's not just me spewing crap. That's according to Jobst Brandt who is probably the foremost expert on the topic. He's a mechanical engineer that worked for Porsche and then went on to work at Avocet Bicycle Products where he designed machines used for testing the traction and breakaway characteristics of bicycle tires. He also authored the book "The Bicycle Wheel".

    like I said " if you know better , which can happen "
    re tread : on motorbikes this is often used to " warm" the shoulders of the tyre to simulate the effect of a softer compound by cause the tyre to " squirm " more when laid over , generating more heat .
    Could the same happen on cycle tyres ? a duel compound effect from a single compound simply by cutting a few groves / slots ? it definatly isn´t to evacuate water , the texture of the road combined with the , relatively , high loading ( kg / sq mm ) prevents aquaplanning except on paint and manholecovers - which don´t have a surface texture of course .

    with road tyres I don´t know BUT with mtb tyres you do need to respect the rotation / usage rules - got the scars to prove it .
