Abstract
The present invention relates to a rim member having an internal support member associated with the rim member. The internal support member includes an outer peripheral surface having an annular groove with the groove having a transverse passageway to permit a tire to be mounted onto the rim member. The transverse passageway consists of two angular positions which communicate through an intermediate section on the internal support member. The invention also relates to a tire construction having an internal rolling surface which engages the outer peripheral surface of the internal support member during the run-flat condition.
Claims21
A run-flat rim member for supporting a deflated vehicle tire includes:
- an annular main body portion providing a mounting for the vehicle tire;
- two sidewall shoulders formed on opposing sides of said annular main body portion and providing an anchoring means for the tire bead sidewall portion mounted on said sidewall shoulders;
- a substantially annular internal support member located between said sidewall shoulder, with said support member having an outer surface greater than said sidewall shoulder and including an annular groove extending around said support member to provide first and second outer peripheral surfaces;
- with said internal support member having at least one annular groove extending therein and having a transverse passageway extending therethrough to permit the wedging of the tire beads onto the rim member;
- said wedging transverse passageway includes an entrance section and an exit section;
- and
- wherein said entrance and exit sections are in different angular positions with respect to the annular main body and communicate with each other through said annular groove without affecting the continuity of the peripheral surface contact.
