A pneumatic tire having a chine extending outwardly from at least one sidewall. The average thickness of the chine, between a point 50% of the width of the chine from the tire sidewall and the end of the chine, is at least 50% of the width of the chine.

Pneumatic tire

A radial ply aircraft tire (11) is mounted upon an H-type rim (10) which was originally designated for use with a bias ply aircraft tire. The ratio of the axial distance (WBF) between the rim flanges to the maximum cross-sectional width (CSWR) of the tire is in the range of 0.7 to 0.9. The ratio of footprint width to footprint length for the tire is in the range of 0.45 to 0.65. Preferably, the carcass (12) and the belts (14) are reinforced with aramid cords. A line (T) which is tangent to a carcass ply (12) and passes through the center of a bead (13) is inclined at an angle (.alpha.) of greater than 60.degree. with respect to the tire's axis of rotation.

Tire

A pneumatic tire having a ground-engaging tread portion. The tread portion has at least two circumferentially extending grooves, each groove having a pair of oppositely disposed sidewalls. One groove sidewall having a first portion extending radially outward in a substantially vertical direction from the base of the groove to a first point spaced a distance from the bottom of the groove a distance no greater than about one-half of the groove depth and a second portion extending from the first point radially outward to the tread surface at an inclined angle. The second groove sidewall extending from the base of the groove to the tread surface at an inclined angle. The included angle between the second portion of the first groove sidewall and the second sidewall being at least thirty degrees (30.degree.).
