Abstract: Provided is a pneumatic tire which is provided with a turbulent flow generation projection for generating a turbulent flow at least in a portion of a surface of the tire and has an outer diameter of not less than 2 m The turbulent flow generation projection extends linearly or curvilinearly along a tire radial direction. A relationship of h=√{1/(V/R)}×coefficient κ is satisfied where “h” is a projection height (mm) from the surface of the tire to a most protruded position of the turbulent flow generation projection, “V” is a speed of a vehicle (km/h), “R” is a tire outer diameter (m), provided that coefficient κ=27.0 to 29.5.

Abstract: A construction vehicle tire, in which a temperature rise at the tread portion is suppressed by enhancing the heat radiation property at the tire center portion (C). Lug grooves (22) are arranged in the tread shoulder regions (S) on both sides in the tire width direction. The tire center portion (C) is formed with narrow grooves (24) extending substantially in the tire width direction (V) and having both ends terminating within the tread. A deep equatorial groove (26) extends in the tire circumferential direction on the tire equatorial plane (CL), and has a maximum depth within the range of from 70% to 110% of the depth of the lug grooves (22), so as to efficiently cool the bottom region (26B) of the deep equatorial groove (26) at high temperature.
