Tubeless Tyres? Not Enough! How about Airless -Michelin TweelTyres

lamborghini · 24th March 2005, 00:25

It has come in a recent ACI issue and has been discussed on this board.
This is to improve ride quality if i am not mistaken.
Seems like a good idea.
I dont think there will be any side walls though.

Just got this in a mail.

New Airless tyres from Michelin.
Look funny to me. Dunno if they would turn out to be as practical as the conventional tyres.

The one mentioned in the photographs is called Michelin Tweel. Michaelin Airless is is a different product. here is a link from Michelin explaining their latest products...

Anyway, I think its practical but they look hideous....:lol

what about the ride.wont those tyres without air in them make it to hard.how are the compensating for that.

on the site its written that tweel has suspension-like characteristics.what exactly is mean by that.

means that the flexible spokes function as a cushion making up for the lack of airin the convetional tyres...hence it ansorbs bumps perhaps the same way as the usual tyre..

aazam · 28th June 2005, 02:52

the spokes wont last when the car jumps they wont be strong enough to handle the hard landing as an average car is about 1tonne and if its in the air for even a second and if its going at 30 kmph the force by which it land would be about 294000nuetons and then even with the best suspension the spokes would have to handle about 1000neuton each then the material may have to be as strong as 6cm of carbonated steel the tyres are not feasable

Michelin, The Next Generation Of Tyres...

They had a pair at the Philadelphia car show. These tires are airless and are scheduled to be out in the market very soon. The bad news for the 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..
No more air valves
No more air compressors at the petrol pumps.
No more repair kits..

These are the actual pictures taken in south carolina plant of Michelin. It will be awhile before they are available to the automotive industries.

Cheers,

Ollie.

P.S: Mods please move this thread if it has already been discussed

looks really wierd......like the car is on rails or somthing

GTS · 2nd November 2006, 18:28

I dont mind if my tyres get punctured, I am going to use the regular ones! These look err...err...

tif0si · 2nd November 2006, 18:30

the plus point would be no flat tyres and one could probably use up the space for the spare tyre for something else, as a spare tyre would not be necessary, from my point of view the negative at the moment is the looks....the normal tyres look much better!

i dont agree wid this coz according to the rules in india, no car can move on indian roads without a spare wheel.....

sumitsingh · 10th November 2006, 09:02

You are right Chocoguy4u,

Currently BMW in India is fighting with the authorities to let their cars be legal since they have run flat tyres and do not come with a spare tyre.. The World moves on and we are still stuck with age old regulations.
