This invention relates to an improved -tire for
a vehicle Wheel and its principal object is to'pro
vide a tire which possesses the advantageous fea
projecting flanges -of the rims and body of the ,
tures of the conventional pneumatic tire, but v
which is not subject to such well-known disad- `
vantages as punctures, blowouts, carcass injury,
etc.
,
to an attaching iiange Vor disk I0 of a wheel or
hub such, for example, as is shown in United
States PatentNo. 2,096,366, granted October 19,

'1937.
Further objects relate to various features 'of

According to the present invention the tire
comprises an annular plate having circumferen-v
tially spaced perforations through which a single
helical spring isV threaded so as to provide alre
silient toroid extending about the plate.` A'paìr

plate so as to embrace the inner periphery of _the
helical spring, each half rim preferably being
formed with lugs, corrugations or the like adapted
to project between the convolutions of the spring
