Claim:
A heavy duty tire having a tire component formed from a rubber composition for a tire, comprising: a rubber component containing 60% by mass or more of a natural rubber component; and a carbon black having a cetyltrimethylammonium bromide (CTAB) specific surface area of 140 to 160 m 2 /g, a ratio (CTAB/IA) of the cetyltrimethylammonium bromide specific surface area to an iodine adsorption number (IA) of 0.85 to 1 m 2 /mg, and a ratio (ΔD50/Dst) of a half width (ΔD50) of Stokes' diameter distribution of aggregates to a Stokes' diameter (Dst) of aggregates, as determined by a centrifugal sedimentation method, of 0.9 to 0.99, the natural rubber component containing 20% by mass or more of highly purified natural rubber per 100% by mass of the natural rubber component.
