Abstract: Provided is a pneumatic tire which is capable of securing a driving stability on dry road surfaces and concurrently of improving snow performance without worsening its pattern noise. The pneumatic tire includes four main grooves each extending in its tread part in a tire circumferential direction, and the four main grooves partition the tread part into: a center land part; paired intermediate land parts located with the center land part being interposed in between; and paired shoulder land parts located with the center land part and the paired intermediate land parts being interposed in between. Each of the intermediate land parts and the shoulder land parts includes multiple V-shaped grooves each configured of: a thick groove part extending in a tire width direction; and a thin groove part extending in the tire circumferential direction.

Abstract: A tire is configured having first and second shoulder rows of shoulder tread elements opposite respective first and second interior rows of interior tread elements, separated respectively by circumferentially extending, zig-zag shaped first and second grooves within a tire tread region. Each groove is defined by opposed shoulder tread elements and interior tread elements and includes a circumferentially continuous see-through central groove portion extending parallel to a circumferential centerplane of the tread. The see-through circumferential grooves communicate with angular intermediate and shoulder lateral grooves having a relatively wide mouth dimension adjacent to a respective circumferential grooves. Staggered in and out shoulder regions within the shoulder tread elements facilitate gripping edges and prevent mud clogging of the shoulder grooves.
