Abstract
PURPOSE:To prevent dust pollution by installing spike pins in circumferential grooves provided on a tread, forming specific tread patterns in the parts other than the grooves, and forming independent air chambers in the inside thereof to make the relative height thereof to the spike pins adjustable. CONSTITUTION:Circumferential grooves are formed on a tread and spike pins 1 are embedded in the grooves. On the other hand, deep cuts are formed in the width direction of tire in the parts other than the grooves, forming a block with several cuts as a unit, and a recessed part is formed between each block to form a tread pattern. An independent air chamber 5 is formed right under each part on which the tread pattern is formed and linked to an independent valve 4 with a pipe 3. And, by feeding/discharging compressed air into and from each independent air chamber via the valve 4, the height of the tread faces are individually adjusted with respect to the spike pins 1. By this structure, dust pollution can be prevented while improving a spiking function.
