The tire has a plurality of radially outer rubber components defining a radially outer surface (S1) exposed to fluids having a relative displacement with respect to the rotating tire. At least one radially outer component has projections, the projections being defined by first sides (2) and second sides (2′) of unequal length. The first sides (2) have a greater length, delimiting therebetween an angle α ranging from 5° to 60° and forming at their intersection an apex (P). The projections protrude by a height (h) from the radially outer surface (S1) from which said first and second sides originate, the height (h) ranging from 0.2 to 100 micrometers. In more than 75% of the projections, any plane tangent to the first side (2) of the projection cuts the radially outer surface (S1) at an acute angle.
A tire having a plurality of radially outer rubber components, the components defining a radially outer surface (S1) of the tire and being exposed to fluids having a relative displacement with respect to the rotating tire, the tire comprising at least one radially outer component having projections, the projections being defined by first sides (2) and second sides (2′) of unequal length, the first sides (2) having the greater length, delimiting therebetween an angle α ranging from 5° to 60° and forming at their intersection an apex (P), which protrudes by a height (h) from the radially outer surface (S1) from which said first and second sides originate, the height (h) ranging from 0.2 to 100 micrometers and in more than 75% of the projections, any plane tangent to the first side (2) of the projection cutting the radially outer surface (S1) at an acute angle.
A mold for manufacturing a rubber tire, the mold comprising surfaces to form a tire having at least one radially outer component having projections, the projections being defined by first sides (2) and second sides (2′) of unequal length, the first sides (2) having the greater length, delimiting therebetween an angle α ranging from 5° to 60° and forming at their intersection an apex (P), which protrudes by a height (h) from the radially outer surface (S1) from which said first and second sides originate, the height (h) ranges from 1 to 100 micrometers;
