Abstract

PURPOSE:To decrease the rotary resistance in the tyre by a method wherein a complex resiliency, a loss resiliency and loss compliance of a tread rubber are set to a specified value, and an effective cross sectional area of a width of the groove in the tread pattern is set to a specified value. CONSTITUTION:The radial tyre has such a feature as its energy loss resiliency E'' related to a bending deformation of the tread rubber is substantially decreased and its loss compliance E''/(E*)<2> related to a compressive deformation (provided that E* is a complex resiliency) is not decreased much to keep various performances such as wet skid etc. Each of the dynamic performance values is set as follows. 30<E*<65(kg/cm<2>), 2<E''<10(kg/cm<2>), 0.5<E''<(E*)<24.0(X10<-3>cm<2>/kg). When the effective cross sectional area in width direction of the groove in the tread pattern is S, tyre outer diameter is D and tread width is W, it is assumed that the effective groove index A is set in a range of 1.1<a=SIGMAS/(DXW)<2.5.
