Title:
PNEUMATIC TIRE, SHOE, TIRE CHAIN, AND PNEUMATIC TIRE VULCANIZATION-MOLD
Document Type and Number:
Japanese Patent JP2009067378
Kind Code:
A
Abstract:

To provide a pneumatic tire providing further improved braking performance from initial use and a pneumatic tire vulcanization-mold.

This pneumatic tire according to the present invention has an Rsk (roughness profile skewness) of zero or greater on land portion surfaces 26S of a tread 16. A structure is thereby achieved in which gaps Z formed between a tread surface and a ground contact surface do not disappear even when the tire contacts the ground. Consequently high braking performance and strong traction force on ice can be secured even when the tire is initially used.
