摘要： A pneumatic tire comprises a carcass layer, a belt layer disposed on the outer side in the tire radial direction of the carcass layer, and tread rubber disposed on the outer side in the tire radial direction of the belt layer. The belt layer is formed by laminating a pair of cross belts having belt angles with an absolute value from 10° to 45° both inclusive and mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° relative to the tire circumferential direction. The distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10≤Gsh/Gcc. The groove depth (Dsh) and under-groove gauge (UDsh) of the outermost circumferential main groove have a relationship satisfying 0.20≤UDsh/Dsh.

摘要： A pneumatic tire comprises a plurality of main grooves extending in a tire circumferential direction, and a plurality of land portions that are partitioned by at least one contact patch end and the plurality of main grooves, the plurality of land portions comprise a center land portion that contains a center in a tire width direction, and a pair of side land portions that are adjacent in the tire width direction to the center land portion, and respective maximum values of amounts by which the pair of side land portions protrude from a tread profile are each greater than a maximum value of an amount by which the center land portion protrudes from the tread profile.

摘要： Technique to increase the endurance of tires comprising two crossed working layers (41, 42), comprising mutually parallel reinforcing elements forming, with the circumferential direction (XX′) of the tire, an angle which is at least equal to 20° and at most equal to 50°. The reinforcing elements are made up of individual metal threads or monofilaments having a cross section which is at least equal to 0.20 mm and at most equal to 0.5 mm. The tire also comprises grooves comprising a radially inferior zone Z1 having a radial height h1 equal to D/3, and a radially superior zone Z2 having a radial height h2 equal to 2D/3. These grooves have a mean width W at least equal to 1 mm and a depth D at least equal to 5 mm, and a maximum width W1 of zone 1, at least equal to 2 mm and a width of zone 2 at most equal to 1 mm.

摘要： A tread for a tire includes a first circumferential main groove, a second circumferential main groove, and a third circumferential main groove. The first, second, and third circumferential main grooves together define a first shoulder rib, a first intermediate rib, a second intermediate rib, and a second shoulder rib. The third circumferential main groove includes a plurality of connecting bridges spaced circumferentially within the third circumferential main groove and axially joining the second intermediate rib and second shoulder rib.
