Abstract:

A radial ply pneumatic tire () features a bead core () which comprises an arrangement of filaments () positioned relative to one another. The bead core () has a cross-section and a radially inward base side (), a radially outermost side (), an axially inward first side (), and an axially outward second side (). In the cross section, the base side () of the bead core () has a width which is substantially linear and is between 50% to 75% of the rim seat width. The bead core base side () is inclined at least 15 relative to the bead's axis of rotation, while the bead heel surface has an as molded inclination at the central portion () radially inward of the bead base () at an angle of at least 10 with respect to the bead's axis. An associated rim () has a pair of humps () and a rim flange () associated with each hump (). Each rim flange () has an axially inward surface (), the distance between each hump () and the axially inward surface () of the associated rim flange () being a rim seat (). The tire () further has a unique toeguard chafer () compound that is cut resistant.
