Abstract: When (I) a tyre 1 is in contact with a flat surface (S) with a camber angle θ of 40 degrees, (II) a load (F) applied to the tyre is increased from zero, and (III) a curve (T) is obtained by plotting, in a XY coordinate, a displacement (Δx) in a tyre axial direction and a displacement (Δy) in a tyre radial direction of a position (A) of one of tyre tread edges (Te) closer to the flat surface (S), the displacements being from a reference position (A0) when the load (F) is zero, inclination of the curve (T) increases as the load (F) increases at least in a range where the load (F) is not more than 78% of a maximum load capacity load of the tyre.
