Description:
Airless tireFrom Wikipedia, the free encyclopediaAirless tireNon-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 2011.[1][2]Naked surfing girls

Mar 19, 2012 - Bicycle/motorcycle tires generate their lateral force primarily through a mechanism called "camber thrust" while automotive tires primarily through a slip angle (angular deformation between wheel and contact batch). You are comparing apples and oranges. Don't act like you know so much about them.. the fact that you don't need air is a very small piece. There are other, more important applications such as generating electricity by weaving nano-muscles into the fibers.

Apr 2, 2012 - Wikipedia - A tire (in American English and Canadian English) or tyre (in Commonwealth Nations such as UK, Australia, and others excluding Canada) is a ring-shaped covering that fits around a wheel rim to protect it and enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.

Apr 13, 2012 - yeah but if a bullet hits that shit the tyre is good to the garbage

Apr 15, 2012 - It is interesting to see how the structure performs in fatigue performance. The tensile/shear strenght. Conventional seel or aluminum deteriorates in fatigue after every use. I don't have any knowledge about composite materials, but I am waiting to see the results. Also, it means this new structure must be machined with a perfection, surface treatment and tolerancing. You can't allow microfissure as it may lead to failures.

Mar 19, 2012 - If NPTs ever do become standard, you can be sure high performance and racing applications now dominated by low-profile pneumatic tires will be the very last ones to convert. NPTs driving characteristics suck and always have. Heavier, louder, less durable at speed, less traction, worse shock absorption. Put some on your bicycle, which are available now, and you will know I'm right. They sacrifice every aspect of performance for the ability to run-flat.
