A pneumatic radial aircraft tire is described having a B/A ranging between 60-70%, wherein B is the width of the tire between the wheel flange, and A is the inflated tire width under rated pressure. The tire may further optionally include a tire bead portion having a Ra/Fr1 relationship which ranges from about 1 to about 2.1, wherein: Ra is the tire heel radius at uninflated and in an new and unused condition, and Fr1 is the wheel flange elliptical radius at the heel section of the tire. The tire may further optionally include a SW/TS ratio which ranges from about 0.1 to about 0.5, wherein SW is the chafer gauge at area A, TS is the total sidewall rubber gauge at area A, wherein A is defined as the region in the sidewall that has a lower radial endpoint defined by the point of contact between the flange and the tire at inflated, unloaded condition, and an upper radial endpoint Ah defined by the tire wheel flange point of contact when the tire is at inflated, and at 100% rated load.

Aircraft radial tire

A tire structure that is especially advantageous for an aircraft tire has a pair of annular elastomeric members (40,41) disposed axially inwardly of the carcass plies (13,14) to maintain the carcass plies in a desired configuration. A preferred arrangement of bead reinforcing strips (32,33,34,35) is disclosed for use in tires that are intended for mounting on H-type aircraft rims.

Sidewall and bead reinforcing structure for a pneumatic aircraft tire

A motorcycle tire particularly for racing motorcycles which has a tread, a pair of beads, and a carcass comprising a single bias ply extending to and around the beads, and a single breaker ply whose width is at least about 85 percent of the tread width and the ends of the single bias ply overlying 50 to 90 percent of the breaker ply. In its uninflated state, the cross-section of the tire suggests a triangle.
