    摘要: A pneumatic radial tire combination for four-wheeled automobile or light truck vehicles. The tire combination has a pair of front steer position tires and a pair of rear position tires. The front steer position tire has a footprint when the tire is normally inflated for normal load that has a footprint shape factor of greater than 1.00 at a 50% load, and about 1.00 at both 85% load and 100% load, the footprint shape factor being defined as the maximum circumferential extent of the tire's footprint at the centerplane of the tire's footprint width divided by the average of the circumferential extent of the tire's footprint width as measured at 40% of the footprint from both sides of the central plane of the footprint. The rear position tire footprint, when the tire is normally inflated for normal load, has a footprint shape factor of about 1.00 at 50% load, and 1.00 or less than 1.00 at 85% load and 100% load when measured similar to the method described for the front position tires.

    摘要: A radial pneumatic light truck or automobile tire 40 having a tread 42 is described. The tread 42 has a base 43, a plurality of traction elements 52 extending radially outwardly from the base 43 and at least one circumferentially continuous wide groove 54,55. The wide groove 54,55 has a circumferentially continuous window 72 extending from the tread base 43 to the radially outer contacting surface 53. The window 72, when viewed in the ground contacting portion of the tread 42, has a shape that is triangular or trapezoidal having two sides 73,74 and a radially outer long base 75. The long base 75 has an axial width of 7% to 20% of the tread width. The wide groove 54,55 has a zig-zag portion 70 extending radially from the tread base 43 in a circumferentially continuous path. The sides 73,74 of the window 72 define the maximum axial extent or amplitude of the zig-zag portion 70 into the wide groove 54,55. Preferably the tread 42 is asymmetrical and non-directional and has two wide grooves 54,55 dividing the plurality of traction elements into three zones 60,61,62, each zone having a different net-to-gross ratio.

    摘要: A pneumatic radial tire combination for four-wheeled automobile or light truck vehicles. The tire combination has a pair of front steer position tires and a pair of rear position tires. The front steer position tire 10 has a first tread arc 46 when the tire is normally inflated for normal load but unloaded, of decreasing radii extending toward the lateral edges 42, 44 and a straight line 50 drawn between the intersection of the tread arc curvature and the centerplane is inclined at an angle &thgr;F of greater than 5° relative to a tangent line L, L being tangent to the tread arc at the centerplane and parallel to the axis of rotation R. The rear tire 20 when similarly measured has a tread arc having an angle &thgr;R of less than 5°.

    摘要: An on/off road radial pneumatic light truck or automobile tire has a tread with at least one wide groove having an average width of at least 7% of the tread width. At least two axially adjacent rows of traction elements are separated by the wide groove. The tread has a plurality of protrusions extending from traction elements into the wide groove. The protrusions are sloped radially inwardly at an angle in the range of 20.degree. to 60.degree. relative to the radial direction from the outer surface of the traction element toward the tread base and crossing axially more than halfway across the wide groove width toward an intersection of a lateral groove and the wide groove. The protrusions extending from traction elements on one side of the wide groove are circumferentially offset and at least partially axially aligned with protrusions extending from traction elements on the opposite side of the wide groove.
