PURPOSE:To restrain a swing (shimmy motion) of a steering wheel caused by inertial travel or the like without deteriorating maneuvering stability and abrasion resistance. CONSTITUTION:The largest width of a belt layer 7 is set in 0.9 to 1.1 times of a tread width TW, and JIS Shore hardness Hs of tread rubber 9 is set in 55 to 70 degrees. A tread rubber thickness Tc on the tread end E up to a tread surface from the belt layer 7 is set in 0.80 to 0.95 time of a tread rubber thickness Ta on a tire equatorial surface, and a tread rubber thickness Tb in a tread intermediate position Q on a tread surface distant by a distance L of 1/4 time the tread width TW from the tire equatorial surface is set larger than the tread rubber thickness Tc, and is set in 0.85 to 0.98 time the tread rubber thickness Ta. |
