摘要： A pneumatic tire has a tread portion divided into a crown rib, a pair of middle ribs and a pair of shoulder ribs by two crown main grooves and two shoulder main grooves. The width of the crown main groove is 5.5 to 7.5% of the tread width. The width of the shoulder main groove is 50 to 70% of the crown main groove width. The crown rib has crown sipes extending from the crown main grooves. The middle rib has axially inner middle sipes extending axially outward from the crown main groove and ending within the middle rib, and axially outer middle sipes extending axially inward from the shoulder main groove and ending within the middle rib. The shoulder rib has shoulder sipes extending axially outward from the shoulder main groove, and shoulder lug grooves extending axially inward from the tread edge ending within the shoulder rib.

摘要： A pneumatic tire 1 is provided in the tread portion 2 with crown blocks 21 each circumferentially divided into two block pieces 28, and shoulder blocks 9 each circumferentially partially divided into two block pieces 15. The block pieces 28 of the crown block 21 are a first block piece 28A having an axially outer crown chamfer 30 abutting on a shoulder main groove 3, and a second block piece 28B having no chamfer abutting on the shoulder main groove 3. The block pieces 15 of the shoulder block 9 are a first block piece 15A having an axially inner shoulder chamfer 16 abutting on the shoulder main groove 3, and a second block piece 15B having no chamfer abutting on the shoulder main groove 3. On both sides of the shoulder main groove 3, the axially inner shoulder chamfers 16 are partially circumferentially overlapped with the axially outer crown chamfers 30.

摘要： Provided is a tire provided with a mark capable of reducing the air resistance during tire rotation while maintaining good visibility. A tire is provided with a mark on a tire side portion. The mark includes a first mark located on an outer side in a tire radial direction, and a second mark located inward of the first mark in the tire radial direction. Each of the first mark and the second mark includes a recess that is recessed from a side profile surface of the tire side portion. A depth of the recess of the first mark from the side profile surface is smaller than a depth of the recess of the second mark from the side profile surface.
