  • Patent number: 5363895
    Abstract: A bias ply pneumatic tire 40,80 is disclosed. The tire 40,80 has a tread 42,82 with a plurality of circumferentially continuous grooves 52,72 and a plurality of laterally extending grooves 50,70. The grooves define tread elements 60,90 of parallelogram shape. Each lateral groove 50,70 includes a portion 53,73 extending from a tread edge a distance of at least 5% of the tread width (W). The portion of the groove 53,73 adjacent a tread edge is inclined less than relative to a plane passing through the axis of rotation, preferably inclined The tread elements 60,90 preferably have radially extending groove walls having an outer portion 69A,79A inclined at and an inner portion 69B,79B inclined at least relative to the radial direction. The tire is particularly well-suited for a rear drive tire for Sprint car racing vehicles.

  • Patent number: 5014762
    Abstract: A pneumatic tire (10, 40) having a belt reinforcing structure (24) located between the carcass (12) and the tread portion (20) is reinforced with an overlay belt (30) located between the belt reinforcing structure (24) and the tread (20). The overlay belt (30) has a plurality of parallel cords (32) oriented at an angle with respect to the equatorial plane (EP) of the tire. The angle of the cords (32) is between to degrees. The overlay can be used by itself or in conjunction with a pair of belt reinforcing strips (42) located radially outwardly along both axial edges (46, 48) of one of the belts (26, 28) of the belt reinforcing structure (24). The belt reinforcing strips (42) also contain a plurality of cords (50) oriented at an angle of from to with respect to the equatorial plane of the tires.

  • Patent number: 4722378
    Abstract: The tread (28) of a tire (10) has a plurality of traction elements (34), each of which has a ground-engaging surface. The ground-engaging surfaces are convex in either an axial direction, a circumferential direction, or both directions. The convex paths followed by the ground-engaging surfaces vary between ground-engaging surfaces across the axial width of the tread in relationship to the unit tread pressure of the tire, and may also vary between ground-engaging surfaces that are axially aligned but located at different places around the circumference of the tire.

  • Patent number: 4688617
    Abstract: A pneumatic vehicle tire (10) has a plurality of radial carcass plies (16,18). One of the carcass plies (16) has a high turn-up that ends under the belt reinforcing structure (42). The other carcass ply (18) has its lateral edges (34,36) located radially inwardly of the widest part of the tire (SD).
