A tire (1), intended in particular for a private passenger vehicle and comprising at least one sidewall (3) with a protuberance of the sidewall (3) close to the connection of the tire with its mounting rim (2), and intended to reduce the aerodynamic drag and hence the resistance to forward motion of the wheel, in order to contribute to the reduction in fuel consumption and hence to the reduction in CO2 emissions. According to the invention, when the tire (1) is mounted on the rim (2) and inflated to a pressure as defined by the “ETRTO” standard, the radially inner end I of the protuberance (6) is positioned radially inside the radially outermost point J of the rim flange (21) at a radial distance H1 at most equal to 10 mm, or radially outside the radially outermost point J of the rim flange (21) at a radial distance H1 at most equal to 4 mm.

A non-pneumatic tire includes a lower ring having a first diameter and an upper ring having a second diameter greater than the first diameter. The upper ring is substantially coaxial with the lower ring. The non-pneumatic tire further includes support structure extending between the lower ring and the upper ring. The non-pneumatic tire also includes an upper sidewall having an annulus shape that covers a portion of a first side of the support structure. The upper sidewall has an inner diameter that is greater than the first diameter.

A tire includes a plurality of side blocks arrayed at a predetermined interval in a tire circumferential direction in a buttress portion. The side blocks include a short portion and a long portion arrayed in a Y shape and a slit that defines a connection portion of the short portion and the long portion and are disposed with a top portion of the Y shape facing toward an inner side in a tire radial direction. A radial height Hb of the side blocks is in the range 0.20≤Hb/SH≤0.50 with respect to a tire cross-sectional height SH.
