PURPOSE: A tread block structure for a heavy duty tire is provided to maximally reduce driving stability loss and abrasion loss which is generated at an end of a block when a vehicle is driven on a dry road and to improve traction efficiency and grip efficiency on tread surfaces. CONSTITUTION: A tread block structure for a heavy duty tire comprises grooves and rectangular shaped block bodies(2) which directly touch a road. The block bodies are connected with the bottom of a leading end portion(4) which is the first to come in contact with the road when a tire moves by being inclined from 10 degrees to 20 degrees based on a connection point of the tread and a predetermined virtual line. The bottom of a trailing portion(7) which is the final contact point with the road is connected with the connection portion of the tread by being inclined and rounded from 20 degrees to 40 degrees based on the predetermined vertical line.
