Abstract
A pneumatic tire to be fitted on a wheel wherein a position, in which a disc is connected to a rim, is offset from the cneter of width of the rim toward the outer surface of the wheel, characterized in that a ratio (Ho/Hi) of an attenuation coefficient Ho (=Go.times.tan.delta.o) determined on the basis of an average thickness Go of an outer side wall of the tire on the outer side of the wheel and a loss factor tan.delta.o of the rubber of this side wall to that Hi (=Gi.times.tan.delta.i) determined on the basis of an average thickness Gi of an inner side wall of the tire on the inner side of the wheel and a loss factor tan.delta.i of the rubber of this side wall is set in the range of 1.2-6.5.
