Abstract: A device for preventing excessive increase of an internal pressure of a rolling assembly, the rolling assembly having a rotation axis and comprising a wheel and a tire, the tire being mounted onto the wheel creating an inner cavity surrounded by a wheel internal surface and a tire internal surface, comprises a cold spot placed in the inner cavity of the rolling assembly for condensing vapor contained in a gas filled in the inner cavity.

Abstract: A tire, the speed rating of which is at least V, comprises a tread, having a volumetric void ratio at least equal to 2% and at most equal to 20%, having a central part Pc comprising at least one groove, and two lateral parts PI each having a volumetric void ratio at most equal to 2%. The central part Pc of the tread has an axial width at most equal to one third of the axial width LBDR of the tread, and any portion of the central part Pc of the tread that is circumferentially delimited by two meridian planes separated by a circumferential distance dc equal to one tenth of the outer perimeter P of the tire comprises at least one and at most three grooves that open onto the meridian planes delimiting the portion in question.
