摘要： A tire having a rotation timing indication hole of the invention has a rotation timing indication hole comprising a multi-step hole provided in a tire tread, and respective steps of the hole have different contours from each other. Since the contour of the hole changes when the tire is worn, the rotation timing of the tire can be recognized.

摘要： A pneumatic tire is provided in the tread portion with circumferential grooves, main oblique grooves and auxiliary oblique grooves. The circumferential grooves include: a pair of axially outer grooves disposed one on each side of the tire equator; and at least one axially inner groove between the axially outer grooves, so as to divide the tread portion into at least four circumferential regions including: a pair of axially inner regions between the axially outer grooves and said at least one axially inner groove; and a pair of axially outer regions axially outside the axially outer grooves. The axially inner regions have an axial width L1 of from 0.15 to 0.25 times the critical tread width TW1. The main oblique groove extends across one of the axially inner regions so that the axially outer end is connected with the adjacent axially outer circumferential groove and the axially inner end is connected with the adjacent axially inner groove. The main oblique groove has an inclination angle θ1 of from 45 to 90 degrees at the axially outer end thereof, and an inclination angle θ2 at the axially inner end thereof which is less than the inclination angle θ1, when measured with respect to the tire circumferential direction. The auxiliary oblique grooves are arranged alternately with the main oblique grooves, and each extends from the adjacent axially outer circumferential groove to one of the axially adjacent main oblique grooves.

摘要： A pneumatic tire comprises a tread portion provided with a nonlinear rib having an amplitude having a center in the tire axial direction. In a normally loaded condition of the tire, the tread portion has an outside tread edge and an inside tread edge when the camber angle of the tire is 0 degrees. In the normally loaded condition, when the a camber angle of 4 degrees is given to the tire to inline towards the outside tread edge, a foot print shape of the tire has a maximum circumferential length at an axial position MC which is off the tire equator towards the outside tread edge. The nonlinear rib is positioned off the tire equator towards the outside tread edge such that the axial position MC lies within the amplitude of the nonlinear rib, and one of the edges of the nonlinear rib on the outside tread edge side is chamfered.
