Abstract
A tire comprises a tread portion provided with a tread profile. The axial distance Lfrom the tire equator to a contact point Pbetween the tread profile and a tangential line thereto at which the angle θ of the tangential line becomes 3 degrees with respect to the tire-axial-direction line, is smaller than 65% of a half tread width Tw. The difference (θ−θ) of an angle θof the tangential line at an axial position Papart from the tire equator by 90% of the half tread width Tw, from an angle θof the tangential line at an axial position Papart from the tire equator by 60% of the half tread width Tw, is in a range from 7 to 12 degrees.
