A new method for designing a tire comprises the steps of laying up a tire having a stiff lower sidewall portion () that has a high modulus apex () and a high turn-up () and a concave shape, a flexible upper sidewall portion () that is decoupled from the tread (). The tread () is supported by a wedge () and extended belts () to substantially eliminate lateral curvature. The tire of the invention also has a rhothat comprises 60% of the section height (SH) of the tire and a shoulder radius that defines a convex shape in upper sidewall portion ().

Tire design based on first principles of structural engineering

An apparatus which uses a sensing device for measuring gauges of elastomeric or rigid articles, or runout of elastomeric articles, has a pivoting arm which holds a means for creating a signal, and is movable relative to the object being measured. The means for creating a signal provides a signal to the sensing device, and the magnitude of the signal depends on the position of the pivoting arm relative to the object being measured. Movement of the pivoting arm, caused by changes in the dimensions of the object, can be recorded and analyzed.
