Abstract
A pneumatic tire with an increased load carrying capacity (extended load index) but compatible with conventional, commercially available wheel rims, has a modified carcass plyline. The tire has a tread area, a carcass structure including two bead areas each comprising a bead, at least one cord-reinforced elastomeric ply extending between the two bead areas, and two sidewalls, one sidewall extending between the tread area and each bead area. The tire is characterized by: a section width defined by lines L and L disposed orthogonally to an axis of rotation of the tire and at equal distances on either side of the equatorial plane of the tire; a plyline that follows the meridional path of a radially and axially outermost one of the at least one ply; points P P on the plyline, being located where the plyline is axially outside of one of the beads and simultaneously at a minimum radial distance of dp dp respectively, from the axis of rotation AR; lines M and M each parallel to, and axially inwards of, lines L and L respectively, and passing through points P and P respectively; a first distance of 1 mm to 5 mm being the spacing from line L to line M and from line L to line M limiting radial distances r and r that exceed the distances dp and dp respectively, by a value of 30% to 70% of a section height SH of the tire; and the plyline extending radially outward in each sidewall to the limiting radial distance r r without axially deviating from lines M M respectively, by more than a second distance of 0 mm to 5 mm.
