摘要： A pneumatic tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, a carcass extending between the pair of bead portions, and an inner rubber extending between the pair of bead portions on an inner side of the carcass. The inner rubber includes a first portion extending in the tread portion with a first thickness and a second portion extending in each of or one of the pair of sidewall portions with a second thickness. The first thickness is greater than the second thickness. In a tire meridian cross-section, a cross-sectional area of the inner rubber is in a range from 1.5% to 10% of an inner-cavity cross-sectional area of the pneumatic tire.

摘要： The invention relates to a self-sealing vehicle tyre comprising a belt package (2), a tread (1) arranged radially above the belt package (2), and an air-tight inner layer (4) arranged radially inside, wherein the self-sealing of the vehicle tyre is obtained via a sealing material layer (5) subsequently attached radially inside after the vulcanisation of the vehicle tyre, wherein the sealing material layer (5) is substantially the width of the belt package (2) and is arranged substantially in the projection thereof, and has a cross-section, formed in the cross-sectional plane containing the tyre axis, with a surface (5a) running in the axial direction substantially in parallel to the belt package, and a surface (5b) running substantially in the radial direction. The invention is characterised in that at least the surface (5a) of the sealing material layer running in the axial direction substantially in parallel to the belt package has a coating (6) all around, which contains at least one alkali salt of at least one fatty acid and/or at least one earth alkali salt of at least one fatty acid.
