Abstract

The present application discloses an electrically and thermally conductive tire comprising a tread having a crown comprising at least one crown rubber mixture for contacting a road while driving, and at least three circumferential grooves; at least one part of the side wall and the bottom of each circumferential groove is formed by a circumferential groove reinforcing piece, the circumferential groove positioned near the center of the equator of the crown is provided with a first groove reinforcing piece, and the grooves positioned at the tire shoulder parts on the two sides are provided with second groove reinforcing pieces; the thermal conductivity, the electrical conductivity and the modulus of the first groove reinforcer and the second groove reinforcer are higher than those of crown rubber; the thermal conductivity, the electrical conductivity and the modulus of the first groove reinforcer are higher than those of the second groove reinforcer. According to the application, the groove reinforcing pieces with good electric conduction and heat conduction performance are arranged in the circumferential grooves of the tread, so that the electric conduction and heat conduction performance of the middle part of the tread and the tire shoulder area can be improved, and the rolling resistance of the tire is improved.

本申请公开了一种导电导热轮胎，其包括胎面，胎面具有胎冠,该胎冠包括至少一种用于在行驶时接触道路的胎冠橡胶混合物,以及至少三个圆周凹槽；每个所述圆周凹槽的侧壁和底部的至少一部分由周向凹槽加强件形成，位于胎冠赤道中心附近的所述圆周凹槽具有第一凹槽加强件，位于两侧胎肩部的所述凹槽具有第二凹槽加强件；所述第一凹槽加强件和所述第二凹槽加强件的导热性、导电性及模量高于胎冠部橡胶；所述第一凹槽加强件的导热性、导电性及模量高于所述第二凹槽加强件。本申请在胎面周向凹槽中设置导电导热性能良好的凹槽增强件，能够改善胎面中部及胎肩区域的导电和导热性能，改善轮胎滚动阻力。
