A pneumatic radial tire for passenger vehicles. When the tire is fitted on a rim and having an internal pressure of 250 kPa or higher, the section width SW and the outer diameter OD of the tire satisfy a predetermined relationship. A center land row is a rib-shaped land, and has center lug grooves each opening into one of the two circumferential main grooves and terminating within the center land row. Outer land rows are rib-shaped lands, each outer land row having outer lug grooves and outer auxiliary lug grooves. The outer lug grooves each open into a ground contact end in the tire width direction and terminate within the outer land row. The outer auxiliary lug grooves open into the circumferential main groove defining the outer land row, has a groove width smaller than the groove width of the outer lug grooves, and extend in the tread width direction.
