Abstract
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.
