A radial tire for industrial vehicles such as a forklift truck, shovel truck, and straddle carrier which are used for cargo handling, having a tread reinforced with a plurality of stiff cord layers placed one over the other such as steel cord which is superior in cut resistance, said cord layers being arranged between said carcass ply and said tread and in proximity to said carcass ply, said tread having a large number of stepwise grooves arranged in the circumferential direction of the tire, characterized in that the raised portion divided by the stepwise grooves has at least one secondary groove which has a narrower groove width, and is superior in traction and braking performance, cut resistance, puncture resistance, wear resistance, heat resistance, and lateral stability.

DETAILED DESCRIPTION It is an object of this invention to provide a pneumatic tire for industrial vehicles which is free of the above-mentioned disadvantages encountered in the conventional ones and is superior in traction and braking performance, cut resistance, puncture resistance, wear resistance, heat resistance, and lateral stability.
The tire of this invention will increase efficiency and save cost in cargo handling operations.
