Abstract

The present invention provides a pneumatic tire in which on-road performance, off-road performance, riding comfort performance, and noise performance are improved in a balanced manner. The pneumatic tire (1) of the present invention is provided with a plurality of main grooves (3) extending continuously in a zigzag shape in the tire circumferential direction and a plurality of lateral grooves (4) extending in the tire axial direction on the tread portion (2). . The main groove (3) includes a pair of shoulder main grooves (6) arranged on both sides of the tire equator C. The lateral grooves (4) include a plurality of shoulder lateral grooves (17) extending from each shoulder main groove (6) to a tread end (Te) on the tire axially outer side. The maximum groove width W8 of the shoulder transverse groove (17) is 0.2-0.6 times of the maximum groove width W1 of the shoulder main groove (6).

Description

technical field

[0001] The present invention relates to a pneumatic tire which improves road performance, off-road performance, riding comfort performance and noise performance in a balanced manner. Background technique

[0002] Conventionally, as pneumatic tires for vehicles (such as SUVs, four-wheel drive vehicles, etc.) intended to run on paved roads and uneven roads, road performance on paved roads and off-road performance on uneven roads are required. Take care. Road performance includes, for example, dry road performance and wet road performance. In addition, off-road performance includes, for example, mud performance and snow performance. Furthermore, in recent years, such pneumatic tires have been required to have high ride comfort performance and noise performance on paved roads, and it is necessary to improve each required performance in a balanced manner.

[0003] For example, Patent Document 1 below proposes a pneumatic tire in which dry performance, mud perfo...
