| 摘要 |
The purpose of the present invention is to increase the durability of an aircraft tire by promoting the dissipation of heat from circumferential grooves of a tread. A tread (12) is formed with a plurality of circumferential grooves (central circumferential grooves (14) and terminal circumferential grooves (16)) extending in a tire circumferential direction. In a tire circumferential cross section, a groove bottom (18) of at least one circumferential groove has a wavy shape with an amplitude in a tire radius direction. |
