PROBLEM TO BE SOLVED: To provide a tire for an industrial vehicle capable of preventing unforeseen accidents by easily and certainly recognizing rotation of a large tire in a tire production process. SOLUTION: 1 represents the large tire and 2 represents a tire sidewall portion. Colored rubber layers 3 identifiable from the color of the tire are discontinuously arranged in the peripheral direction of the sidewall portion 2. In this embodiment, the identification rubber layers 3 to which rubber sheets made of light-colored rubber adhere at a predetermined width are arranged at three portions at an interval of 120°. At least one layer or more of migration preventing rubber layers 4 preventing contaminant entering into the tire rubber from being migrated into the identification rubber layers 3 are arranged between a tire surface 1a and the identification rubber layers 3. The migration preventing rubber layers 4 are widely arranged to cover the width of the identification rubber layers 3. It is preferable that the migration preventing rubber layers 4 consist of a rubber composition containing butyl rubber (IIR: an isobutene-isoprene copolymer) or acrylonitrile-butadiene rubber (NBR).
