Abstract
A pneumatic tire has a circumferentially continuously extending wide groove having a width of from 35 to 45 mm disposed in a tread center. A part on each side of the wide groove, which is defined as extending at least 10 mm axially outwards from the groove edge, forms a substantially continuous rib part. A part between the rib part and a tread edge has circumferentially discontinuous grooves so that: an axially inner part has a land ratio La of not less than 90%; a middle part has a land ratio of Lb in a range of from 80 to 90%; and an axially outer part has a land ratio Lc in a range of from 85 to 95%, wherein the axially inner part, middle part and axially outer part are three equiwidth parts between the wide groove and the tread edge.
