摘要： The temperature of the tread surface part of a tire (20) is increased by running the tire (20) in contact with a drum (26). The increase in the temperature of the tread surface part is due to the heat of friction between the tread surface part and the drum (26). Because large increases in temperature indicate that the friction is causing a large amount of wear, it is possible to forecast with ease the amount of wear of the tire from the increase in temperature of the tread surface part. The temperature of the tread surface part can be measured using a thermography machine (14), and the wear in the tread can be determined by looking at an image that shows the temperature.

摘要： A pneumatic tire (10) has, in the surface of the tread (11), a central circumferential groove (12) located at the center of the contact patch width and extending circumferentially around the tire, a plurality of longitudinal grooves (13 (13a, 13b)) formed on the axially outside of the central circumferential groove (12), lug grooves (15), and blocks (16 (16a to 16c)) defined by the central circumferential groove (12), the longitudinal grooves (13), and the lug grooves (15). Each of the lug grooves (15) is formed such that its width in the shoulder region is greater than its width in the central region, and the sum of the groove area of the central circumferential groove (12) and the groove area of the longitudinal grooves (13) is smaller than the area of the lug grooves (15). As a result, the pneumatic tire (10) not only secures the wet braking performance and wear resistance performance on paved roads, but also improves the acceleration performance and braking performance and the steering stability performance on snowy roads.

摘要： By forming a ground contact edge side of lug grooves (16) such that the groove depth becomes shallower in groove depth from the tire equatorial plane side toward the ground contact edge, and by setting an average angle of inclination (¸1) formed between a tread face (12A) and a groove bottom (16B) to be not more than 5°, water expulsion is performed smoothly in the vicinity of the ground contact edge while securing the rigidity of land portions in the vicinity of the ground contact edge. This enables a high degree of both wet performance and dry performance to be achieved.
