Abstract
PURPOSE:To reduce the rigidity of a tread at the end of a land part and prevent the partial abrasion of the tread by arranging many sheetings of specific length at the predetermined intervals on the end of a land part formed on the tread and cellulated with grooves. CONSTITUTION:A tire 11 has a tread 13 striding over a pair of shoulders 12. And many grooves 15 extending in zigzag toward the periphery of the tire 11 are formed in the tread 13, thereby cellulating many ribs (land parts) 16. In the aforesaid constitution, many sheetings 17 are arranged respectively at the end 16a of each rib 16 and the end of the tread 13. And the length l of each sheeting 17 in the cross sectional direction of the tire 11 is set to 1mm-3mm, and the intervals (d) of the sheetings 17 in the peripheral direction of the tire 11 are set to 1mm-4mm. Also, each sheeting 17 is so sized that the length la of the tread 13 in the initial stage of abrasion to the length lb thereof in the final stage of abrasion can be set to be constant.
