The ratio T2/A is such that T2/A≤1.00. The rim width code is equal to the measuring rim width code for the tire size minus 0.5.

A rubber composition comprising 50 phr to 100 phr of a styrene butadiene rubber; 0 phr to 50 phr of at least one diene based rubber; 95 phr to 200 phr of filler comprising i) 50 phr to 100 phr of silica, ii) 40 phr to 70 phr of carbon black and iii) 5 phr to 30 phr of an inorganic metal hydroxide; 40 phr to 80 phr of plasticizer comprising a hydrocarbon resin having a softening point within a range of 80° C. and 130° C.

The tire (11) for a passenger vehicle comprises a crown (12), two beads (32), two sidewalls (30) each connecting each bead (32) to the crown (12), and a carcass reinforcement (34) anchored in each bead (32). The tire (11) has a load index Ll such that Ll≥Ll′+1 and Ll′ being the load index of an EXTRA LOAD tire of the same size in accordance with the manual of the ETRTO 2019 standard. The tire (11) has a sidewall height H defined by H=SW×AR/100, where SW is the nominal section width and AR is the nominal aspect ratio of the tire in accordance with the manual of the ETRTO 2019 standard, such that H≥95. The carcass reinforcement (34) comprises two carcass layers (36, 37).

A tire physical information estimation system includes a physical information estimation unit and a data acquisition unit. The physical information estimation unit includes a learning type arithmetic model including an input layer through an output layer to estimate physical information related to a tire produced in association with movement of the tire. The data acquisition unit acquires input data input to the input layer. The arithmetic model includes a feature extraction unit that performs a convolution operation in an operation halfway between the input layer and the output layer to extract a feature amount.

A tyre includes a tread portion including a first middle land portion, a second middle land portion, a first shoulder land portion, and a second shoulder land portion. The first middle land portion is provided with first middle lateral grooves terminating within the first middle land portion, the second middle land portion is provided with second middle lateral grooves terminating within the second middle land portion, the first shoulder land portion is provided with first shoulder lateral grooves, and the second shoulder land portion is provided with second shoulder lateral grooves. The first middle lateral grooves and the second middle lateral grooves are inclined in a first direction with respect to the tyre axial direction, and the first shoulder lateral grooves and the second shoulder lateral grooves are inclined in a second direction opposite to the first direction with respect to the tyre axial direction.

The circumferential groove and the circumferential groove of the pneumatic tire are formed inside than a tire equatorial line when mounted to the vehicle. In an outside center land portion and an inside center land portion, linear width direction sipes, width direction sipes and width direction sipes inclined with respect to the tire width direction are formed along the tire width direction. An inside shoulder land portion has a slick portion in which the surface of the inside shoulder land portion is slick in a grounding region of the inside shoulder land portion in a state where normal load is loaded on a tire.

A tire with a tread reinforcing layer that includes a ply reinforcing structure formed by winding a cord-embedded rubber tape circumferentially of the tire. The ply reinforcing structure includes first oblique segments and second oblique segments which intersect with each other to form a mesh structure having rhombic spaces. The circumferential lengths of the rhombic spaces are less than ⅔ times the maximum circumferential length of the ground contacting patch of the tire in its normally loaded state.

A tyre includes a tread portion including a crown land portion defined between two main grooves extending continuously in a tyre circumferential direction. The crown land portion is provided with crown lateral grooves traversing the crown land portion. Each of the crown lateral grooves, in a cross-sectional view perpendicular to its longitudinal direction, includes a sipe portion having a width equal to or less than 1.5 mm, and a main portion connected to the sipe portion and opening at a ground contact surface of the crown land portion. The main portion has a width enlarging from the sipe portion. The main portion has a depth smaller than depths of the main grooves. The sipe portion has a first wall extending in a tyre radial direction so as to be continuous with a first wall of the main portion to form a single groove wall together.

A tire in which an elongation at break and/or compounding of a rubber composition of a tread.
