Airless tire test Humvee vs Hummer
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

► 2012 Chevy Sonic makes a bungee jump!
When Chevrolet decided to launch the all-new Sonic in the States, it seems
they took the word 'launch' a little too seriously.
On the back of research that showed extreme sports to be highly popular
within the car's 18-30 target customer range, the company decided to make
quite an impact by throwing a car from the top of a ten storey tower in
Long Beach, California.
Well, we say impact. But just before it plummeted to the ground, the
all-new Aveo dipped its nose in a paddling pool and bounced back up in an
incredible display of non-contact automotive bungee-jumping.
The stunt was performed as part of Chevrolet's 'Let's do this' marketing
campaign in the USA.
The Bungee Jump is the second extreme sport in which the Aveo has
participated. Last month, the car was launched more quickly than any car in
history -- accelerating from 0-60mph in just 0.4 seconds as it was pushed
out of an aeroplane, to perform its first freefall skydive.

A kick flip -- a 360-degree rotation in mid-air -- is a common stunt on a
skateboard. Not so much in a vehicle. But Dyrdek, host of MTV's Fantasy
Factory and Ridiculousness, and the Chevy Sonic are up for trying firsts
