Extreme AMPHIBIOUS Russian offroad vehicle: Aton-Impulse VIKING-2992
4x4xAMPHIBIOUS, VIKING combines the best of extreme off-road with internal
floatation and water-jet powered amphibious capability.
The ATON IMPULSE VIKING-2992 is a unique special purpose vehicle, ideal for
heavy industry, exploration, arctic use, flood-relief, NGOs, rescue and
emergency services. VIKING is the only amphibious off-road vehicle in the
world to have passed through certification to meet UN/ECE regulations for
unrestricted ON-ROAD USE.
VIKING's world-leading amphibious capabilities are based around its
purpose-designed flotation construction, centrally mounted engine and
powerful water-jet propulsion enable it to ford open water at speeds of up
to 15 km/h. The vehicle's wheels may be optionally engaged while in
amphibious mode, providing unique ability to cope with shallow water and to
transit the challenging littoral zone, where other vehicles commonly become
stuck in soft mud.
Off-road, VIKING is overwhelmingly superior to comparable amphibians, with
cross-country ability akin to tracked vehicles. High maneuverability,
turn-over resistance and endurance provide safety and comfort in remote or
With a curb weight of only 1.46 tonnes, riding on giant 1300x600x533 tires,
VIKING's exceptionally low ground pressure enables it to "float" on soft
snow surfaces and avoids damage to sensitive environments. VIKING has
independent pneumatic front and rear wheel suspension with adjustable
clearance and a tire air-pressure adjustment system operable from the cab
while driving the vehicle.
VIKING's is designed for security and endurance rather than high speed,
which in any case is hazardous on rough terrain. Top speed on-road is 50
mph at 16.8 mpg; off-road at 11.8 mpg, currently limited by the tires (cost
$700 each) speed rating. ATON IMPULSE is bringing out new, higher-speed
rated, custom tires, as well as bullet proof tires. More powerful engine
models will be fitted in future models.
The VIKING-2992 will for the first time be available for international
purchase in late 2012.

Retreading the Tweel Airless Skid Steer Tire and Wheel
Pete's Tire Barns, Inc, has successfully retreaded the Michelin Tweel
Airless Skid Steer Tire and Wheel. The Michelin Tweel is a revolutionary
tire and wheel assembly for skid steer machines that uses high strength
poly resin spokes instead of air to support the load of the machine. This
allows for a virtually zero down time tire without the drawbacks and
limitations of solid skid steer tires.
Pete's Tire Barns believes that they are the first retread shop in the
country to successfully retread a Michelin Tweel. After buffing down the
surface of the Tweel, Pete's retread technicians Dennis McCarthy and Jared
Derosiers filled in the remaining gaps with rubber and applied a new tread.
After curing for more then 4 hours under both heat and pressure, a high
quality retreaded Tweel rolled out of their retread plant in Orange, MA.
"The ability to retread this revolutionary product maximizes the value for
our customers and saves landfill space" said Pete's Tire Barns President
Peter Gerry. The next test for this retreaded MichelinTweel will be in the
field and Pete's Tire Barns has scheduled a real world test for the tire in
a local glass recycling facility. With a goal of extending the life of the
tire and providing value to the customer, Pete's Tire Barns has found a
About Pete's Tire Barns: Pete's Tire Barns, Inc, headquartered in Orange,
MA, has grown to one of the largest independent commercial tire dealerships

England, a brand new state-of-the art Distribution Center, and 2 Bandag
retread facilities. The company employs in excess of 200 people, and
operates a fleet of over 130 service and delivery vehicles. In 2013, Pete's
Tire Barns celebrated their 45th year in business and has consistently been

Airless tire test Humvee vs Hummer
From Wikipedia, the free encyclopedia
Non-pneumatic tires (NPT), or Airless tires, are tires that are not
supported by air pressure. They are used on some small vehicles such as
riding lawn mowers and motorized golf carts. They are also used on heavy
equipment such as backhoes, which are required to operate on sites such as
building demolition, where tire puncture is likely. Tires composed of
closed-cell polyurethane foam are also made for bicycles and wheelchairs.
The main advantage of airless tires is that they cannot go flat, but they
are far less common than air filled tires.
Airless tires generally have higher rolling resistance and provide much
less suspension than similarly shaped and sized pneumatic tires. Other
problems for airless tires include dissipating the heat buildup that occurs
when they are driven. Airless tires are often filled with compressed
polymers (plastic), rather than air.
Michelin is currently developing an integrated tire and wheel combination,
the "Tweel" (derived from "tire" and "wheel," which, as the name "Tweel"
suggests, are combined into one new, fused part), that operates entirely
without air. Michelin claims its "Tweel" has load carrying, shock
absorbing, and handling characteristics that compare favorably to
conventional pneumatic tires. Automotive engineering group of mechanical
engineering department at Clemson University is developing a low energy
loss airless tire with Michelin through the NIST ATP project.
Resilient Technologies and the University of Wisconsin--Madison's Polymer
Engineering Center are creating a "non-pneumatic tire", which is basically
a round polymeric honeycomb wrapped with a thick, black tread. The initial
version of the tire is for the Humvee and is expected to be available in
