1. An insert for a vehicle wheel suitable for being inserted in an inner annular cavity resulting between a tire and a rim of the vehicle wheel, said insert comprising an annular element extending in a circumferential direction (C) about a main axis (X-X), said insert being made in one piece of polymeric material and having an upper surface suitable for facing towards a tread inner side opposite to a tread of the tire and arranged in the inner annular cavity, a right sidewall and a left sidewall suitable for facing towards a right lateral wall and a left lateral wall of the tire, respectively, and a lower surface suitable for at least partially coming into contact with the rim of the vehicle wheel,
the upper surface coming into contact, at least partially, with the tire when the tire is deflated, and not touching the tire when the tire is inflated to a predetermined working pressure,
wherein dips or protrusions are formed on the annular element, relative to a main encumbrance surface of the annular element, said dips or protrusions each extending at least partially on the upper surface, on the lower surface, on the right sidewall and on the left sidewall of the annular element, about the circumferential direction (C) and prevalently along a respective preferential extension direction (A-A), which lies on a plane secant to said circumferential direction (C) at an acute angle, so that passage of air during tire inflation is facilitated when a point of air injection into the wheel is situated at one of said dips or between two of said protrusions.
