<p>A heavy duty tire, wherein, a minimum position Qt where a tread thickness T from a second belt pry (7B) is a minimum value Tmin is provided in an area Y apart 0.5 to 0.7 times a tread ground-contact surface half width (WT/2) from a tire equator C, the ratio Tmin/Tc of the minimum value Tmin to the tread thickness Tc at the tire equator C is 0.92 to 0.97 and the ratio Tb/Tc of the tread thickness Tb at the outer end of the second belt ply (7B) to the tread thickness Tc is 0.95 to 1.10, a minimum position Qk where a tread thickness K from a carcass (6) is a minimum value Kmin is provided in the area Y, and the ratio Kmin/Kc of the minimum value Kmin to a tread thickness Kc at the tire equator C is 0.97 to 0.998 and the ratio Kb/Kc of a tread thickness Kb at the outer end of the second belt ply (7B) to the tread thickness Kc is 1.2 to 1.5.</p> |
