PURPOSE:To improve shock absorbing quality and climbing performance and to prevent a lawn from being damaged, by providing plural spikes to be implanted in a tread part, which eliminates the ruggedness, and filling a tire with air of predetermined low pressure, in the case of the captioned tire which runs on the lawn. CONSTITUTION:A tire main unit 2 arranges a cord of a carcass 7 at an angle about 90 deg. with respect to the center surface in the tire circumferential direction, and a tread part 3 of the tire main unit 2 substantially eliminates a rugged part. And the tread part 3 provides plural spikes 5 to be implanted. This spike 5 is divided into a nail part 8, forming its one end to a cone shape, and an implanted part by a flange part 10, and the spike 5 sets its protruding height L1 above or below about 10mm by embedding the implanted part 9 in the tire main unit 2. And air, with which a tire is filled, is set to a pressure of 0.1-1.0kg/cm<2>. By this constitution, the tire improves its shock absorbing quality and climbing performance further enables damage of a lawn to be reduced. |
