Michelin Tweel Tyre Development

When I first saw this post i thought that the prototype Michelin tyre called the Michelin Tweel Tyre. Consequently which had been developed for real time use.  But looking at this I think not.

The new tyre is tall and narrow 165/50 x 18 will be the size used. This will make the tyre much more dynamic with far less rolling resistance. So, it will be like going back in time 50 years to Michelin’s first radials. They would have been 125 x 400 milimetric size (tall and thin). You know what they say “what comes round goes round”.

It was back in 2005 when the French tyre company first announced the arrival of the Michelin Tweel Tyre . To me it just looks like a light weight solid fork truck wheel with a wheel that has a solid rubber welded to the wheel on the outside. It could also be said to look like the old fashioned horse cart wheel, with the spokes fixed to a hub that is connected to the axle. The spokes then fit to the outer wheel, which is fitted with a rubber band.

The difference is in the materials that Michelin Tweel have used.

The same as the cart wheel. Traditionally, a solid inner hub mounts to the axle. Similar to a normal spokes alloy wheel. From this is another set of spokes that connect to the outer rim, the same as a cart wheel. These spokes are incredibly strong and are the things that replace the air pressure in a conventional tyre. The outer part of the Michelin Tweel Tyre rim is connected with a band of rubber with a tread pattern.

The second spokes that absorb all the impacts and bumps and respond to the cars steering are made from polyurethane and are incredibly strong. The French Company say that these spokes can be made of different strength and tensions, to enable the Michelin Tweel Tyre to be fitted to different vehicles of different weights and physical size, to help improve the handling, much in the same way as a conventional tyre and wheel assembly does at the moment. As I have said earlier in my article these Michelin Tweel Tyre do look like a mixture of the old cart wheels and modern alloy wheels and tyres and in my opinion area very clever concept.

Michelin have said that the Tweels have been tried and tested on an Audi A4

Naturally, giving the car much more lateral stiffness than the conventional wheel and tyre set up. In my opinion Michelin are a massive tyre company and I cannot see them giving up their core business, to make things like this, but I do think that the Tweel may be part of a big mix of technologies in the future.

Hi I would like to introduce myself. I have worked in the Garage and Michelin Winter Tyre and Car Battery business now for 40 years. So, working for a couple of national tyre companies before starting my first business. Now owning a company here in the UK called Pellon Tyre and Auto-centre. Of course, I am a keen blogger about anything to do with cars and their related products. Of course, that will help my business to grow.

For as long as we can remember tyres of all shapes and sizes have always to filled with air-filled rubber tubing. This is to put it to its simplest terms. As a result, the latest tyre designs are a far cry from the old cycle tyres.  Mr Michelin first made these in France well over 100 years ago.

Michelin looks for models for the future

Airless Tweel Wheel Tyre

Airless Tweel Wheel Tyre substitute will now be available for many of the small urban vehicles.These are used in cities across Europe. They will replace the conventional rubber tyres .

as a result, almost all the leading tyre companies are looking for the concept tyre designs for future urban cars and Michelin tyres are no exception. The first idea started to come out of the Michelin Laboratories in about 2005. The new concept was to become the “Tweel” a simple cross between the tyre and the wheel, this is where the name comes from, the “T” from the tyre and the Airless Tweel Wheel Tyre.

The Airless Tweel Wheel Tyre looks like a giant bicycle wheel, probably a futuristic version of the original solid bicycle wheel that Michelin worked on over 100 years ago. The tweel has a solid hub, with spokes and an outer rim. Materials that are used, will be manufactured, using a polyurethane type substance, which is a hard material and light in weight. The tyre tread is stretch fitted onto the spokes in a rubber band similar to the tyres mounted on fork trucks. This construction looks very solid yet flexible. These have the spokes absorbing all the shocks, just like air would do in a tyre, but having the advantage of “not having punctures”.

In addition, Michelin, has been testing different cars with the tweel fitted. Furthermore, this  includes the Audi with good handling results. They admit though that they are still in the early stages of development. I think it is good to try other materials to try out to replace rubber products. A large amount of oil, is used for making tyres? and we are running out of oil ?.
