The bias tire is modelled as an elastically-supported ring in order to study its lateral deflection characteristics. The elastic properties of cord/rubber laminates imply that circumferential stiffness of the sidewall should be included in a lateral deformation model of the bias tire. The relatively large camber stiffness of bias as compared to radial tires is explained in terms of the variation in rolling radius that occurs across the tread width of the bias tire when it is inclined.
