text: In 1946, Michelin created steel-belt radial tires, which were longer-lasting, more durable, and offered reduced resistance, enabling advances in fuel efficiency.

text: The rolling resistance of the tire according to the invention is considerably reduced by satisfying all of the above requirements, i.e. by the weight-saving of the tire due to the thinning of the rubber gauge in the side portion and the arrangement of the base rubber on at least both side edge parts of the belt as a tread rubber without actually exerting a bad influence upon the skid resistance of the tire and also by the arrangement of the super-hard bead filler rubber having a Shore A hardness of 80°-95°, which brings about the thinning of the rubber gauge in the side portion as well as the improvement of the ride feeling, without reducing the cornering stability of the tire, whereby the fuel consumption of the vehicle from the decreased rolling resistance of the tire can effectively be suppressed.
text: In addition, when the pneumatic tire is partitioned with the first boundary lines and the second boundary lines into the first region to the third region, and the values are obtained by dividing the cross-sectional areas SA, SB, and SC of the first region to third region by the peripheral lengths a, b, and c along the tire inner surface of the first region to third region, by satisfying the relationships 7.5≦SA/a≦11.5 and 2.0≦SB/b≦6.0 for the ratios SA/a and SB/b, the volumes of the first region and the second region of the pneumatic tire are reduced to the minimum necessary, the increase in tire weight associated with the extension of the developed tread width TDW is minimized, and the rolling resistance can be reduced.
text: In this way, the volume of the third region of the pneumatic tire is reduced to the minimum necessary, so the tire weight and the rolling resistance can be further reduced.
text: In the pneumatic tire as described above, by having the ratios SA/a and SB/b satisfy the relationships 7.5≦SA/a≦11.5 and 2.0≦SB/b≦6.0, the volumes (the substantial average thickness) of the first region A and the second region B of the pneumatic tire are reduced to the minimum necessary, so the tire weight can be greatly reduced without loss of tire performance such as the wear resistance or cut resistance, and accordingly the rolling resistance can be greatly reduced.
text: Therefore, the increase in the tire weight associated with the extension of the developed tread width TDW can be minimized and the rolling resistance can be reduced.
text: In contradistinction to the above solutions of the prior art, the invention of the application resides in the discovery that by suitably modifying the carcass radial surface profile the rolling resistance of a tire can be remarkably reduced and simultaneously the steering stability and the riding comfortability against vibration can also be improved without adversely affecting the wet performance and durability of the tire.
