| A low compaction cantilevered tire construction is provided which is designed for use at relatively low inflation pressures and which has sidewalls with a relatively uniform bending resistance through the majority of the sidewall. When the tire is placed under high loads at low inflation pressures the sidewall deflects substantially radially and allows the tread portion of the tire to maintain its intended shape thus improving the contact area of the tire and providing a tire having a relatively high contact area and thus relatively low soil compaction for a given loading. | ||||||

| Disclosed is a method of designing rubber composite executed as follows. A shape of the rubber composite, a shape of the each part (i) constituting the rubber composite and physical properties of a rubber material used for each part (i) are tentatively selected respectively. Thereafter, the rubber composite is divided into many finite elements, and strain in each element is calculated by the finite element method to obtain maximum principal strain (εi)max of the elements in each part (i). Then, the tentative selections of the shape of the rubber composite, the shape of each part (i) and the physical properties of the rubber material, and the calculations by the finite element method are repeated until an allowance ratio Sia calculated as a ratio of strain (εi)b at break to the maximum strain (εi)max becomes equal to a specified reference allowance ratio S0 or higher in all of the parts (i). The shape of the rubber composite, the shape of each part (i) and the physical properties of the rubber material are thus determined. | ||||||

| A runflat tire is provided that may be used in applications currently requiring a large aspect ratio tire. The runflat tire of the invention may be substituted in these applications while providing desirable ride characteristics. The runflat tire includes a sidewall with a radial portion and a cantilever portion. The cantilever portion may be fabricated by extending a sidewall insert in the axially inward direction or by extending the bead filler in the axially outward direction. In other embodiments, the cantilever sidewall portion is formed by a combination of the sidewall insert and the bead filler. The resulting runflat tire has desired durability in the uninflated operating condition while having desired ride characteristics in the inflated condition. The sidewall structure allows the tire to be used in applications presently requiring a tire with a high aspect ratio. | ||||||
