View Full Version : (New tire technology) Michelin "Tweels"..

04-19-2006, 10:19 AM
"Michelin, the company that invented the radial tire, has rolled out a radical new concept called the Tweel. As this prototype demonstrates, the traditional rubber tire and solid wheel duo is replaced by a tread bonded to a strong loop of composite material. The vehicle's weight hangs from a series of polymer plastic spokes that connect this loop to the hub. The flexible Tweel can bear the load of a pneumatic tire four times its size, it can cushion bumps five times better than a pneumatic tire, and the contact area can be nearly doubled for improved handling.

Noise, mass, and rolling resistance still need to be improved before this promising new technology is ready for high-speed, high-load passenger-car applications.

Thought you might like to see the next generation of tires. They had a pair at the Philadelphia & Detroit Car shows. These tires are airless and are scheduled to be out on the market very so on. The bad news for law enforcement is that spike strips will not work on these tires.

This is what great R&D will do and just think of the impact on existing technology:

a.. no more air valves.
b.. no more air compressors at gas stations.
c.. no more repair kits."

Hahaha that looks sick! Almost scary... But what is the "deformable wheel? They have to be special wheels made for these tires? That sucks.. They look huge too.

Here's an article on it... (page takes forever to load but it gets there)


The heart of Tweel innovation is its deceptively simple looking hub and spoke design that replaces the need for air pressure while delivering performance previously only available from pneumatic tires.

The flexible spokes are fused with a flexible wheel that deforms to absorb shock and rebound with ease. Without the air needed by conventional tires, Tweel still delivers pneumatic-like performance in weight-carrying capacity, ride comfort, and the ability to "envelope" road hazards.

Michelin has also found that it can tune Tweel performances independently of each other, which is a significant change from conventional tires. This means that vertical stiffness (which primarily affects ride comfort) and lateral stiffness (which affects handling and cornering) can both be optimised, pushing the performance envelope in these applications and enabling new performances not possible for current inflated tires.

sigh ... no more stretched tires for me. *sad*

You are a year too late:

yea, this is so old man.

I saw them at the detroit auto show back in 2004... even talked to the rep for a while about the pro & cons. I didn't recall ever seeing a thread on them, and someone just emailed me this info... so I decided to share it with maX. Sorry for the repost.

whatever thanks randy. May be old news to other but im sure there are plenty who hanven't heard of it before.

and yes, rubber will be on the sidewalls to keep the spokes from packing with snow/dirt.

never heard of this before. if they handle well, i'd sport em, i actually like the look

05-04-2006, 03:10 PM
wow, cool

but scarry-looking

thanks for the info! i wonder when they will come into use

and if Michelin has a patent on them, imagne what it will do to all the other tire companies if these things catch on...

so what if the disgruntled ex cuts off the sidewall.. will the roadside warranty cover that? hehe
