The elliptically-shaped tire has a pair of oppositely-opposed bead cores, a carcass structure each end of which is wrapped around a bead core, an apex disposed between the carcass structure and each of the ends thereof, a pair of oppositely-opposed sidewalls overlying the carcass structure, a chafer strip positioned between the carcass structure and each of the sidewalls, and a tread overlying the carcass structure and a belt reinforcing structure positioned therebetween. The carcass structure has a carcass aspect ratio of about 60. Additionally, the tire has a pair of oppositely-opposed sidewall portions having a relatively thin radially outer portion and a relatively thick radially inner portion.

Pneumatic tire

Tire tread and buttress

A tubeless pneumatic tire having means in the lower bead portions of the tire for preventing the tire from being inflated when the tire is mounted on a wheel having a rim diameter smaller than for which it was designed.

Pneumatic tire having air escape means

A tread for a pneumatic tire having a plurality of circumferentially spaced independent projections. The tread has three narrow zones which extend circumferentially about the tire; a central zone and two shoulder zones. The depth of the recesses in between the independent projections in these zones is substantially less than the depth of the recesses in between the projections in the remaining portion of the tread.

Tread for pneumatic tire

A tread for a pneumatic tire having a plurality of circumferentially spaced independent projections, each projection has an outer configuration which is basically triangular as viewed in a plane perpendicular to the tread. The projections in the central portion of the tread are oriented such that the leading edges form an angle from about 30.degree. to 60.degree. with respect to the mid-circumferential plane of the tire, and the projections in the shoulder portions are oriented such that the leading edges form an angle from about 30.degree. to 70.degree. with respect to the mid-circumferential plane of the tire.
