A pneumatic vehicle tire has a nominal tire cross-sectional height H of at most 110 mm, bead regions with bead cores, a radial carcass which runs around the bead cores in the bead regions axially on the inside to axially on the outside forming carcass turn-ups, and side wall regions, which each have a wing profile and a side wall profile. The wing profiles are the only rubber components extending in contact with the radial carcass in the radially outer region of the side wall region. The carcass turn-ups end at a radial height (h.sub.1), determined from a base line, of 15 mm to 65 mm. At least in a region between a radial height (h.sub.2) of 29% of the nominal side wall height and a radial height (h.sub.3) of at least 80% of the height H, the wing profiles are the only rubber components that extend outside the radial carcass.

The present invention relates to a tyre (100) for vehicle wheels comprising at least one carcass structure (101), a tread band (109) applied in a position radially external to said carcass structure, and a pair of sidewalls (108) applied laterally on the opposite sides with respect to said carcass structure, where on at least one sidewall of said pair of sidewalls (108), a label (120) is applied comprising a protective layer (121), an adhesive layer (123), and possibly one or more ink layers (122) interposed between said protective layer (121) and said adhesive layer (123), where said adhesive layer (123) adheres the label (120) to the surface of said sidewall, where said protective layer (121) comprises polyester-based and/or polyether-based cross-linked aliphatic polyurethanes exhibiting dynamic elastic modulus values E′, measured at 25° C., static tensile deformation 1%, dynamic deformation +0.1%, and frequency 1 Hz, equal to or higher than about 5 MPa, and a residual deformation measured at 25° C. after 4 cycles of deformation from 0% to 12%, equal to or lower than about 1%.

In a pneumatic tire, a two-dimensional code is provided on a surface of side rubber provided in a side portion. The two-dimensional code is formed of a dot pattern including two types of gray scale elements identifiably formed using surface irregularities. A two-dimensional code range in a tire radial direction in which the two-dimensional code is provided lies outward or inward of a bead filler rubber edge located outward of bead filler rubber in the tire radial direction.

Provided is a tire including a pigment mixture that is capable of changing color with a change in temperature and/or light, wherein one or more of a tread part, a sidewall part, and a spoke part of the tire include a color-changing part including the pigment mixture, and the pigment mixture includes two or more selected from the group consisting of a temperature-sensitive pigment, a light-sensitive pigment, and a photoluminescent pigment.

In a tire 2 of the present invention, sidewalls 6 each include an outer layer 6a, and an inner layer 6b disposed inward of the outer layer 6a in the axial direction. The inner side end, in the radial direction, of the inner layer 6a extends to a region between a bead 10 and a chafer 8. When Po represents a contact point, on an outer surface of the tire 2, at which the outer layer 6a and the chafer 8 contact with each other, an inner side end, in the radial direction, of the outer layer 6a is equal to the contact point Po. In the radial direction, an outer side end 44 of the chafer 8 is disposed outward of the contact point Po. In the radial direction, an inner side end 46 of the inner layer 6b is disposed inward of the contact point Po.

A pneumatic tire has a rim strip rubber. A radial height of the rim strip rubber on the basis of an outer diameter position of a bead core is equal to or more than 70% of a radial height of a tire outer diameter position. An upper end of a side reinforcing layer is arranged closer to an outer side radially than an upper end of a bead filler. A distance from a tire maximum width position to the upper end of the side reinforcing layer is equal to or less than 5 mm. The maximum thickness Tw of the rim strip rubber between the upper end of the bead filler and the upper end of the side reinforcing layer is greater than the maximum thickness Tm of the rim strip rubber closer to the outer side radially than the upper end of the side reinforcing layer.
