This invention relates to improvements in wheel struc
tures for motor vehicles, and more particularly an auto
mobile wheel structure provided with means to support
the wheel in the event of a blowout or puncture causing
the associated tire to become de?ated, and serving to
prevent unnecessary damage to the tire.
A main object of the invention is to provide a novel
and improved safety tire and wheel structure which in

with apertured lugs 26 registrable with the apertures 21
and 22 of the disc member 15. -Rigidly secured to the
rim ?ange 19 are respective studs 27 which are spaced so
as to be engageable through apertured lugs 26 and the
apertures 21 and 22 of the disc member ‘15, suitable
clamping nuts 29 being provided on the studs 27 to secure

the annular adjacent plate member 47. As in the pre
said auxiliary tread element and interposed between the
the side wall portion and the annular plate element, the
diameter of said plate element being smaller than the
normal diameter of the tire, whereby the auxiliary tread
element is disposed inwardly of the normal tread portion
of the tire, anannular auxiliary washer mounted in the
rim outwardly adjacent said annular plate element, an
annular locking ring wedgingly engaged on the rim and
‘having aperipheral ?ange outwardly adjacent to and en
gaging said auxiliary washer, a split ring lockingly en
gaged on said‘ rim outwardly adjacent to and engaging
said ?ange, said ?ange exerting inward force on said
viously described form of the invention, the auxiliary
tread elements 52, 52 are located inwardly of the main
tread portion 56 of the tire ‘46. Thus, in the event that
the tire becomes de?ated, the wheel will be supported on
the auxiliary tread elements 52, 52 for a su?icient length
of time to allow the driver to retain control of the vehicle
and to thus avoid a serious accident.
"As shown ‘in FIGURES 4 and 6, the tire 46 may be
