imagine, a Terrain Conforming Wheel (TCW), which
utilizes a totally new concept of mobility. This is
a non-pneumatic wheel, which breaks away from
conventional wheel design and standards. It is not a
static wheel design as is the case of conventional
wheels. This Wheel is a variable design, which
conforms to the terrain it envelopes in a uniform
It has the traction in the range of a track
assembly, well beyond that of a wheel! Yet, it is
not a track assembly- it does not churn the terrain.
It has resistance closer to that of a standard
Since it conforms to the terrain, it is able to
scale objects in its path in a uniform fashion. In
fact, its entire rim contributes to conforming to
them. The Wheel scales the objects from within,
minimizing resistance and jolting.
Ecologically, it is friendly to the terrain it
transverses. It does not churn the terrain, as is
the case with conventional wheels. Actually, the
load bearing mass is not static in relationship to
the wheel itself. The weight oscillates between the
bearing supports of its spokes.
The full circumference of these Wheels is utilized
in gripping the terrain. Thus, in the case of a
four-spoke wheel, it takes the shape of a
parallelogram. In the case of a six- spoke wheel, it
takes the shape of a rounded pyramid (Triangle).
Initially, these TCWs will focus on lower speed and
lower weight applications. Donohue Resilient Wheels,
LLC is a market developmental company which will be
assigning rights to this new Patent pending
(#13340568) technology. Do contact them in your
quest for markets beyond what was possible before.
Here is a link to the article
covering the release of this terrific product!
Here are examples of the TCW mounted onto a standard
The TCW can also be
demonstrated on larger wheels.
Wheels, LLC shows the capacity of its resilient
wheel technology with prototypes of future wheels. They
can widely broaden their contact with the terrain,
absorb shock, flex/swivel transversely, and horizontally
shift their load bearing upon the ground.
This technology is not limited to the models presented.
The desired performance of the wheel is a reflection of
the "selection of parameters" chosen to build it!
In general, these functional mock-ups demonstrate means
for attachment either centrally or through the
cylindrical pivots of the hub, a spoke hinge designed
with fail-safe* in mind and capable of universal action,
and a rim/tire easily removable with a small Allen

band(s) riding within and held in place by an assembly
fasteners and a concave washer. They are restricted
by a crossover, threaded pin (axle) directly above.

“hub assembly of
an axle”. This wheel has an offset rim to partially
the wheel bearing.
II b (Above): Features a smaller hub having four
tubular axles, which allow access for fastening onto
“ hub assembly of an axle”. The revolving
cylindrical pivots act
as sleeves encompassing them.
III (Above): Displays a mid-size wheel with a
relatively small hub.
Notice that this wheel only incorporates a single
steel band within
the tire. The tire is transversely grooved at the
base of each spoke
to facilitate flexing.
IV (Above): Displays a full-size wheel with a
relatively large hub.
Notice that this wheel fastens to the “hub assembly
of an axle”
at its center and has an offset rim to partially
