To provide a stud tire which is configured so that friction of an inner bottom surface of a pin hole can be reduced, although running-through performance and braking performance are maintained for a period as long as possible.SOLUTION: A stud tire 50 comprises: a tire 10 having a plurality of pin holes 12; and a plurality of stud pins 20 which are mounted on the pin holes 12, and whose tip parts protrude from the pin holes 12. The stud pins 20 have pedestals 23 protruding laterally. The pin holes 12 have concave parts 13 engaging with the pedestals 23. The stud tire 50 has non-foamy bodies 40 which are lower in hardness than portions 12s constituting the inner bottom surfaces in the tire 10, between base end surfaces of the stud pins 20 and inner bottom surfaces of the pin holes 12.SELECTED DRAWING: Figure 1

    【課題】スタッドタイヤにおいて、走破性および制動性を極力長い期間維持しつつも、ピン穴の内底面の摩耗を低減する。【解決手段】スタッドタイヤ50は、複数のピン穴12を有するタイヤ10と、ピン穴12に取り付けられて先端部がピン穴12から突出する複数のスタッドピン20と、を有する。スタッドピン20は、側方に突出する台座23を有する。ピン穴12は、台座23と係合する凹部13を有する。スタッドタイヤ50は、スタッドピン20の基端面とピン穴12の内底面との間に、タイヤ10における内底面を構成する部分12sよりも硬度の低い非発泡体40を有する。【選択図】図1
