| 摘要 |
The invention relates to a tyre (10) for a road vehicle, which has a predetermined direction of rotation and comprises fins (16) for modifying the drag and/or lift of the vehicle, arranged on a sidewall (12) of the tyre, forming an angle (α) in a projection plane perpendicular to the axis of the tyre, (α) belonging to the domain [−3&pgr;/8, −&pgr;/12] or [0, +3&pgr;/8]. Each fin (16) extends within a range ]Dm, DM[ of distances from the axis (X) of the tyre, the height of the fin varying continuously as a function of the distance from the axis of revolution (X) of the tyre, while every point of maximum height of the fin is at a distance from the axis (X) of the tyre which is less than or equal to Dm+0.40(DM−Dm). |
