PNEUMATIC TIRE CAPABLE OF PREVENTING THE INCREASE OF TIRE WEIGHT AND THE STRENGTH OF A TIRE WHILE SECURING NECESSARY INTERNAL CUT CHARACTERISTIC

摘要

PURPOSE: A pneumatic tire is provided to reduce the weight of a tire and prevent the increase of a rubber volume while increasing the ride comfort.;CONSTITUTION: A pneumatic tire(1) includes a tread unit(2), a pair of side wall units(3), a bead unit, and a plurality of protect ribs(10). The protect rib has a maximum height unit(11) in which for the height of a warped surface(S). An external slope unit and an internal slop unit are formed in a triangle shape. A distance of a lengthwise direction is 0.1 and o.3 times of lengthwise direction of the protect rib. The tire radial distance from a bead base line of the radius direction outer side end part of a protect rib is composed of 0.6 to 0.8 times of the tire height.;COPYRIGHT KIPO 2012
