PNEUMATIC TIRE
摘要:
A tire (2) includes a tread (4), a wing (6), a sidewall (8), a clinch portion (10), a bead (12), a carcass (14), a support layer (16), a belt (18), a band (20), an inner liner (22) and a chafer (24). A dimple (62) is formed in the sidewall (8) and the clinch portion (10). When air flows into the dimple (62), a turbulent flow is generated. By the turbulent flow, heat of the tire (2) is emitted to an atmosphere. The dimple (62) takes a planar shape of a circle. The dimple (62) has a diameter which is equal to or greater than 6 mm and is equal to or smaller than 18 mm. The dimple (62) has a depth which is equal to or greater than 0.5 mm and is equal to or smaller than 3.0 mm. The tire (2) has a CTT profile.
