不平整地面行驶用的摩托车用轮胎
摘要：
本发明提供一种不平整地面行驶用的摩托车用轮胎，能够维持直行时的牵引性能并且提高转弯性能。在胎面部(2)配置有被胎面沟(10)划分的多个花纹块(B)。花纹块(B)包括多个胎冠花纹块(13)，这些胎冠花纹块踏面(11)的形心(Gb)位于胎冠区域(Cr)，该胎冠区域(Cr)以轮胎赤道(C)为中心且具有胎面展开宽度(TWe)的1/3的展开宽度，胎冠花纹块(13)包括：形心(Gb)与轮胎赤道面(Cp)的距离(L1)在胎面展开宽度(TWe)的2％以内的多个中央胎冠花纹块(13a)、形心(Gb)与轮胎赤道面(Cp)的距离(L2)大于胎面展开宽度(TWe)的2％且在6％以下的多个侧方胎冠花纹块(13b)。
摘要（英）：

A motorcycle tire for running on rough terrain comprises a tread portion (2) having a developed tread width (TWe) and provided with a plurality of tread blocks (B). The tread blocks include a plurality of crown blocks (13) defined as having a ground contacting top surface whose centroid (Gb) is located within a crown region (Cr) defined as having a developed width of 1/3 of the developed tread width (TWe) and centered on the tire equator. The crown blocks include a plurality of central crown blocks (13a) whose axial distance (L1) from the tire equatorial plane to the centroid is not more than 2 % of the developed tread width, and a plurality of off-center crown blocks (13b) whose axial distance (L2) from the tire equatorial plane to the centroid is more than 2 % and not more than 6 % of the developed tread width.
