A TRUCK AND BUS RADIAL TIRE REPRESENTING TIRE PRESSURE AND LOAD CONDITIONS

摘要

PURPOSE: A heavy-duty tire showing the air pressure of load thereof is provided to allow a user to monitor the air pressure and load of the tire with a naked eye by comprising an indicator. CONSTITUTION: A heavy-duty tire showing the air pressure of load thereof comprises a depressed part(111), an indicator(101), and scales(121,122,123). The depressed part is formed in a rectangular shape at regular intervals on the sidewall of the tire in the circumferential direction. The indicator is formed out of an elastic material in a rectangular shape and attached to the depressed part. The scales are indicated on the depressed part in order to show the air pressure and load of the tire as the measurement width of the indicator changes when the tire is transformed by the air pressure and load.
