Abstract PROBLEM TO BE SOLVED: To improve abrasion resistance performance without deteriorating drainage performance.SOLUTION: A pneumatic tire 1 for a heavy load has center land parts 6 and middle land parts 7 formed. In the center land parts 6 center blocks 11 having hexagonal stepping-faces are arrayed in a tire circumference direction by center lateral grooves 9 which connect zigzag top parts of center main grooves 3 having the smallest widths in a tire shaft direction of the center land parts 6 to zigzag top parts of middle main grooves 4. The middle land parts 7 are partitioned into hexagonal middle blocks 17 arrayed in a tire circumference direction by middle lateral grooves 15 which connect zigzag top parts of middle main grooves 4 having the smallest widths in the tire shaft direction of the middle land parts 7 to zigzag top parts of shoulder main grooves 5. An aspect ratio of the middle blocks (LM/WM) is smaller than an aspect ratio of the center blocks (LC/WC).SELECTED DRAWING: Figure 1 【課題】排水性能を悪化させることなく、耐偏摩耗性能を向上させる。【解決手段】センター陸部6、及び、ミドル陸部7が形成された重荷重用空気入りタイヤ1である。センター陸部6は、センター陸部6のタイヤ軸方向の幅が最小となるセンター主溝3のジグザグの頂部とミドル主溝4のジグザグの頂部とを継ぐセンター横溝9によって、踏面が六角形状のセンターブロック11がタイヤ周方向に並んでいる。ミドル陸部7は、ミドル陸部7のタイヤ軸方向の幅が最小となるミドル主溝4のジグザグの頂部とショルダー主溝5のジグザグの頂部とを部分を継ぐミドル横溝15によって、タイヤ周方向に並ぶ六角形状のミドルブロック17に区分される。ミドルブロック縦横比(LM/WM)は、センターブロック縦横比(LC/WC)よりも小である。【選択図】図1
