Abstract: A run-flat tire comprises a tread portion, sidewall portions, bead portions, and a carcass ply extending between the bead portions. The sidewall portions are each provided therein with a sidewall reinforcing rubber layer having a crescent-shaped cross sectional shape and disposed on the axially inside of the carcass ply. The sidewall portions are each provided in the axially outer surface thereof with a rim protector which projects radially outward most on the radially outside of the radially inner edge of the sidewall reinforcing rubber layer. The bead portions are each provided therein with an axially inside core and an axially outside core between which each radially inner edge portion of the carcass ply is secured. When measured along a normal line drawn normally to the carcass ply from an apex of the rim protector, the thickness of the sidewall reinforcing rubber layer is in a range of from 29% to 35% of the thickness of the tire.

Abstract: A pneumatic tire comprises a tread portion which has, on each side of the tire equator, a first tread edge, a second tread edge and a third tread edge which are occurred under tire loads of 100%, 75% and 50% of a regular tire load, respectively. Between the third tread edge and the tire equator, a circumferentially continuously extending main groove is disposed. A shoulder region between the main groove and the first tread edge is provided with a first inclined groove which extends so as to intersect with the first tread edge, the second tread edge and the third tread edge. The depth of the first inclined groove at the first tread edge is smaller than the depth at the second tread edge and the depth at the third tread edge.

Abstract: A tire includes an outboard tread edge and an inboard tread edge to be located on an outboard side and an inboard side of a vehicle, respectively, circumferentially and continuously extending main grooves, and land portions divided by the main grooves. The land portions include an outboard shoulder land portion, an outboard middle land portion, an inboard shoulder land portion, and an inboard middle land portion. Each of the outboard shoulder land portion, the inboard shoulder land portion, and the inboard middle land portion is provided with axially extending lateral grooves. The outboard middle land portion is provided with outboard middle lateral grooves extending from an edge of the outboard middle land portion on the outboard tread edge side toward the inboard tread edge. The outboard middle lateral grooves are inclined with respect to a tire circumferential direction at angles smaller than those of the lateral grooves.
