Abstract
A pneumatic tire having excellent wet performance and steering stability and noise reduction comprises a tread divided into two regions by a pattern center, at least one of which regions is provided with a plurality of main slant grooves each being comprised of a steep slope segment and a gentle slope segment. Furthermore, when such a region is equally divided by a phantom line parallel with the pattern center into a tread central zone and a tread side zone, a steeply slant auxiliary groove communicating two adjoining main slant grooves with each other and a gently slant auxiliary groove arranged between the adjoining two main slant grooves are arranged in the tread side zone.
