摘要： A tread of a tire can include a cap layer and a base layer. A loss tangent of the cap layer at 30° C. may be not greater than 0.30, and a loss tangent of the base layer at 30° C. may be less than the loss tangent of the cap layer at 30° C. The base layer can be inward of a reference end of the tread in an axial direction A fixing layer can be between the cap layer and a carcass in a radial direction. A first end of the fixing layer can be outward of an end of the base layer in the axial direction, or a position of the first end of the fixing layer can coincide with a position of the end of the base layer in the axial direction. Adhesiveness of the fixing layer can be higher than adhesiveness of the cap layer.

摘要： 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).
