Abstract

A pneumatic tire comprises at least three circumferential main grooves (3), at least four land regions (4) including a pair of shoulder land regions (4S), and a plurality of shoulder lateral grooves (5) provided in the shoulder land regions (4S). Groove depths (Hg) of the circumferential main grooves (3) are not greater than 6.3 mm. The shoulder lateral grooves (5) have groove depths (Hymax) at deepest portions in a range of from 75% to 90% of the groove depths (Hg) and groove depths (Hye) at a tread ground contacting edge (Te) in a range of from 63% to 85% of the groove depths (Hg). shoulder regions (Ys) have a land ratio (Ls) smaller than a land ratio (Lc) of crown region (Yc). A ratio tanδ0/tanδ30 of tread rubber (2G) between tanδ0 at 0 degree Celsius and tanδ30 at 30 degrees Celsius thereof is not less than 3.75.
