ah e riguardo il senso di rotazione non mi starei tanto a preoccupare: credenza comune è che la “freccia” disegnata dai tasselli del battistrada (una sorta di “V” più o meno completa) deve essere orientata nel verso di rotazione della ruota. PARE non essere vero poiché consigliano di montare i 2 copertoni da MTB in maniera “opposta” e cioè il posteriore con la V in direzione di marcia (ottimizzato per la trazione), l’anteriore con la V in direzione contraria (Ottimizzato per la frenata). Per i copertoni da BDC non è particolarmente rilevante il senso di rotazione e sono arrivati con la bici montati come suggerito per MTB riporto il commento Mavic: The rear tyre direction is intuitive and should be mounted as if the tread was forming an arrow to show the way to go. The front tyre however is slightly less intuitive and should be mounted so that the tread shows a "V" (instead of an arrow) while you're on the bike looking at it. This is to give better water evacuation in the curves. Should you ride in dry conditions the mounting direction will be of less influence.
E quello di Schwalbe: In the case of a road tire the rolling direction is mainly important for esthetic considerations. Tires marked with arrows simply look more dynamic.
Off road, the rolling direction is far more important, as the tread ensures optimum connection between the tire and the ground. The rear wheel transmits the driving force and the front wheel transmits the braking and steering forces. Driving and braking forces operate in different directions. That is why certain tires are fitted in opposite rotating directions when used as front and rear tires. The “FRONT” arrow indicates the recommended rolling direction for the front wheel and respectively the “REAR” arrow is the direction for the rear wheel.
