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

2009 Campagna T-Rex | Road Tested | Edmunds.com
Campagna Motors builds its line of three-wheelers by hand in Montreal,
Quebec (what is it about Quebec and three-wheelers; there's the Can-Am
Spyder, too). The chassis of the T-Rex is constructed from 1.5-inch tubular
steel and then covered in fiberglass body panels. This three-wheeler
utilizes a double-wishbone suspension at each front wheel and a traditional
motorcycle-style swingarm in the rear. Mounted behind the driver and
passenger is a 197-hp, 1,352cc inline-4 engine and six-speed sequential
manual transmission lifted from the Kawasaki Ninja ZX-14 — one of the
quickest and most powerful motorcycles made today.
