Abstract
A tire or tire and wheel assembly in which the sidewalls are pretensioned before being loaded and/or deflected. Various pretensioning means are disclosed including some for displacing the beads radially, axially or circumferentially, and some for applying a radially outwards force to the tread. There is thus a tendency to lengthen the or each sidewall thereby creating pretension.
