Document Type and Number:
WIPO Patent Application WO/2015/005194
Kind Code:
A1
Abstract:
Provided is a pneumatic tire (T) which makes it possible to improve noise performance while having both steering stability performance on dry road surfaces and driving performance on wet road surfaces. In this pneumatic tire (T), the tread surface (10) has at least four main grooves (11) extending in the tire circumferential direction; these main grooves (11) divide circumferential land portions (12) and shoulder land portions (13) and indicate the mounting direction relative to the vehicle. Multiple lug grooves (14) extending in the tire width direction are formed at intervals in the tire circumference direction on each of the multiple circumferential land portions (12). The lug grooves (14) communicate with the main grooves (11) on the inner side of the vehicle, but on the outer side of the vehicle, said lug grooves (14) terminate within the circumferential land portions (12) without communicating with the main groove (11).
