The harbor tyre is applicable for harbor equipment such as big-tonnage forklifts, pilers, reach stackers and gantry cranes. The tyre body is tight, the tyre bead is specially treated, the support capability is reinforced, the generation of heat is low, and the tread of tyre has wide running area, massive and deepened patterns, as a result, the tyre has excellent gripping power and braking performance and also has extremely good stability and operating safety under a heavy load condition. Because of the application of the wear resistant formula, the tread of tyre has good wear resistance and the tyre has long service life. Because the tyre is good in air tightness, the air supply frequency is reduced, the tyre body is made of materials which are low in generation of heat and good in adhesive property, so the probability of bead separation is greatly lowered; in addition, the tyre can be renewed for many times, therefore the use cost of the tyre is lowered.
