Abstract
A tire assembly ( ) having runflat capability comprises a tire ( ) mounted to a rim ( ) to provide a tire cavity ( ) defined by a carcass circumferential inner surface ( ), two sidewall inner surfaces ( A, B) and the rim. The tire assembly ( ) is characterized by having a platform ( ) disposed circumferentially around the rim within the tire cavity and one or more hoops ( A- C) disposed within the tire cavity ( ) between the platform ( ) and the carcass circumferential inner surface ( ) so that under normal inflation the one or more hoops do not contact either the carcass circumferential inner surface ( ) or the sidewall inner surfaces ( A, B), but below a first runflat inflation pressure, the one or more hoops ( A- C) contact and support the carcass circumferential inner surface ( ).
