| Method for designing a tyre comprising a plurality of structural parts which are different from each other in terms of size, composition or position within the cross section of said tyre, which includes the steps of defining at least one profile of said tyre on the basis of a group of predefined dimensional constraints, defining remaining profiles on the basis of correlations between dimensional values of said structural parts, defining within the cross section the shape of said structural parts, filling each shape with a basic component depending on the composition of the structural part defined by said shape. | ||||||
| 62 | Tire and method for correcting tire uniformity thereof | US09510859 | 2000-02-23 | US06673184B1 | 2004-01-06 | Robert Walter Brown; Paul Harry Sandstrom |
| According to the invention, a pneumatic tire and method of manufacturing the pneumatic tire having improved tire uniformity characteristics is disclosed. The carcass reinforcement ply has a plurality of reinforcement cords embedded in a matrix material that can be rendered plastic and non-plastic to, respectively, permit and restricts reorientation of the reinforcement cords after the tire has been at least partially vulcanized. The method includes the steps of rendering the matrix material plastic, reorienting one or more reinforcement cords without their being stretched beyond their elastic limits, and then rendering the matrix material non-plastic. The reorientation can occur while the tire is still in the tire mold or when the tire is still hot from the tire mold and at a temperature of at least the deflection temperature by applying a force for reorienting the reinforcement cords. | ||||||

| A pneumatic radial ply tire with an aspect ratio of less than 50 has a ground contacting tread radially outward of a circumferential belt structure which in turn is radially ourtward of a carcass structure. The carcass structure has a pair of bead areas that include a bead foot compatible with a conventionally-shaped wheel rim having flanges with laterally extending portions. The carcass structure has a cord-reinforced elastomeric ply layer extend laterally between the two bead areas and radially inward of the belt structure. The tread area is directly connected to the bead areas without a sidewall. Rim flange protectors comprising a continuous circumferential elastomeric projection extend laterally outward from each bead/tread area and thereby radially outward of the rim flanges. | ||||||
| 65 | Method of estimating tire performance | US09530886 | 2000-05-05 | US06430993B1 | 2002-08-13 | Eisuke Seta |
| The estimation of the performance of an actually used tire in the presence of a fluid, such as drainage performance, in-snow performance, and noise performance. A tire model and a fluid model based on a finite element method are constructed from a draft design of a tire including the shape, structure, and the like, and a road surface condition is inputted by selecting a coefficient of friction &mgr; in conjunction with the construction of a road surface model (Steps 100 to 106). Boundary conditions during tire rolling or tire nonrolling are set (Step 108); deformation calculation and fluid calculation of the tire model are performed (Steps 110 to 114); and a boundary surface between the tire model and the fluid model is recognized to update the boundary conditions (Steps 118 and 120). The result of calculation is outputted as a result of estimation, the result of estimation is evaluated (Step 122), and the draft design with satisfactory performance is adopted (Step 124 to 132). If the performance is unsatisfactory, the draft design is changed (corrected) (Step 134). | ||||||

| 69 | Compression sidewall tire reinforced for deflated operation | US290534 | 1981-08-06 | US4341249A | 1982-07-27 | Thomas N. H. Welter |
| A compression sidewall tire reinforced for operation while deflated. A pair of junction portions connect the sidewalls and shoulders. Each of the shoulders extends axially outward and radially inward from the tread, and each of the sidewalls extends axially outward and radially outward from the mounting portions. The sidewalls are constrained against outward expansion by the rim and junction portions. The shoulders are reinforced with a plurality of circumferentially spaced ribs to resist movement toward the ground when the tire is deflated and under normal load. A circumferentially continuous rib may also be positioned on the exterior surface of each junction portion to further reinforce the tire. | ||||||

| A pneumatic tire for motor vehicles having a generally trapezoidal section with a top portion which is generally convex towards the outside and wider than any other part of the tire, beads, and two sidewalls. The sidewalls spread outwardly from the beads to zones which connect the sidewalls with the top portion. The top portion has a central tread portion which is normally in contact with the ground when the tire is under load, and lateral shoulders which are spaced from the ground during rectilinear running of the vehicle. The sidewalls have zones which are less resistant to bending adjacent to the shoulders and adjacent to the beads than the parts which are intermediate the shoulders and beads. The less resistant zones act as hinges under load on the tread. A generally annular reinforcing structure for the tread, which is substantially inextensible in the axial and circumferential direction, is folded at its ends about reinforcing annular straps arranged in each shoulder. In any radial section, the cincture connection angle, which is the angle between a straight line drawn through the center of the hinge adjacent to each shoulder and parallel to the tire axis and a straight line drawn through the center of the shoulder hinge and the center of the strap, is between -10.degree. and 30.degree.. | ||||||

| A low pressure, pneumatic tire is provided with a flexible tread belt that extends outwardly beyond the sidewalls respectively adjacent thereto when the sidewalls are flexed under normal load. The configuration and stiffness of the belt is such that the load carried by the tire is effectively spread beyond the width of the flexed torus. At the same time, local deformation of the belt can take place in such a way to fold up over the flexed sidewalls to prevent them from damage by shock or abrasion caused by objects striking the sidewalls. | ||||||
| 72 | Tire with supportable sidewalls | US64288 | 1979-08-06 | US4253511A | 1981-03-03 | Walter W. Curtiss, Jr. |
| A tire and a tire and rim assembly. The rim comprises a pair of annular support members extending axially outwardly of a pair of bead seat surfaces. The axial width of a tread of the tire is greater than the axial distance between the annular support members. A plurality of sidewall appendages are connected on the exterior surfaces of the sidewalls of the tire such that they are spaced apart from the annular support members when the tire is inflated and in supporting contact with the annular support members when the tire is uninflated and under load. The sidewall appendages extend radially and axially along the sidewalls such distances that when the tire is uninflated and under normal load, the support members support the sidewall appendages to maintain the shape of the sidewalls substantially the same as when the tire is under normal inflation pressure and load. | ||||||

| A slightly bulged outwardly arched pneumatic vehicle tire having a tread which is narrow in relation to the width of the tire. The tire also has a belt which is pull-resistant in the circumferential direction of the tire and effects the lateral stabilization of the tire. Portions of the belt are arranged on both sides of and adjacent to the tread in sections of the tire sidewalls which are essentially cylindrical or slightly conical. In addition, the reinforcing inserts form the belt. Those reinforcing inserts located in the tire sidewalls form a considerably smaller angle with the circumferential direction of the tire than do those reinforcing inserts located below the tread. | ||||||

| Pneumatic vehicle tires having a carcass with a tread strip centrally arranged thereon. The carcass freely spans the wheel rim and is only slightly outwardly curved when in a non-depressed condition. At its rim area the carcass is deflected by means of its arc of curvature towards the tire beads which are reinforced with pull-resistant cores. The carcass has a thickness which continuously decreases from its maximum thickness in the region of the tire bead to a fraction thereof at the edges of the tread strip. The carcass is provided with two fabric plies which are looped around the cores. Decreasing in distance between each other, the two plies extend beneath the tread strips. In the arc of curvature the two plies surround an elastic, deformable, incompressible intermediate layer which has an approximately wedge-shaped cross section. | ||||||
| 75 | Wide radial tire and rim therefor | US45550674 | 1974-03-27 | US3910336A | 1975-10-07 | BOILEAU JACQUES |
| A radial or partially radial tire has a ratio H/B of height to breadth less than one and a carcass reinforcement having a neutral fiber that follows, at least between the midheight of the respective sidewalls and the respective bead rings, the natural equilibrium curve of a single-ply radial carcass that is without a tread reinforcement and that is subjected to internal pressure, the curve being tangent to the bead rings and passing through the edges of the tread reinforcement and through points where the sidewalls have a maximum distance from each other. The wheel rim for mounting the tire is formed at each edge with a portion substantially parallel to the adjacent segment of the neutral fiber of the carcass reinforcement. This portion is connected to the adjoining bead seat by an S-shaped curve and is terminated on the outside by a curvature towards the axis of rotation of the tire.

| A pneumatic tire for vehicle wheels which includes a tread, an annular reinforcing structure, two sidewalls, two beads and having a plurality of slits in the inner and outer surfaces of the sidewalls which may come into contact with other surfaces of the tire or wheel in consequence of the deflation of the tire. The slits are prevailingly oriented in a direction perpendicular to the direction in which takes place the relative slidings between the contact surfaces. Each sidewall has a cross-section along meridian planes of such a shape that its section midline in the meridian plane has a convexity directed towards the tire inside and a flexional rigidity in the meridian plane such that the convexity does not change in direction even under normal operating inflation pressure. The flexional rigidity has a value which is smaller than that of the analogous rigidity of the remaining portions of the sidewall.

| 79 | Dual tire | US36630173 | 1973-06-01 | US3830273A | 1974-08-20 | BOILEAU J |
| A tire is formed with two treads spaced transversely from each other, two sidewalls terminating in beads reinforced with bead wires, and, between the treads, a connection comprising in its center a wire rod forming a closed loop of diameter intermediate between that of the bead wires and that of the treads. Each tread has its own independent reinforcement, and each sidewall has a rigid zone close to the bead and a flexible zone close to the tread. The connection has on opposite sides of the central wire rod substantially the same structure and the same equilibrium profile when the tire is inflated, and therefore the same radial flexibility, as the flexible zones of the two sidewalls.
