Is Graphene Tire Revolution Finally Coming?

Hehe... ESB "Search found 957 matches: Graphene"...
... and "Search found 21 matches: Graphene tire"... includes:
Grips better, less rolling resistance, and possibly the fastest tire on the market.. But Graphene will never to be more than some "unicorn".. I'm just embarrassed for you dude.
Meanwhile...

Is Graphene Tyre Revolution Finally Coming? Hehe... Funny Euro folks... "tire" spelled funny... :wink:
http://www.bike-eu.com/sales-trends/nie ... g-10133257

Starts:
LOMAZZO, Italy – Is it finally living up to the promises; is the revolution in tyres really coming now? It appears so now a new patent has been announced by Graphene producer Directa Plus while bigger orders have been placed by the one and only bicycle tyre maker using this wonder material; Vittoria.
Includes:
Graphene Plus patent

For using the Graphene additive in its compounds Vittoria entered into a joint venture with Directa Plus SpA. This company recently announced that it has received the patent for Graphene Plus (G+) elastomeric composition for tyres. G+ simultaneously reduces resistance and increases grip in automobile, motorcycle and bicycle tyres.

Directa Plus got the patent from the Italian Patent and Trademark Office. It’s for the product and application of its new graphene based solution for enhancing the performance of tyres. Specifically, the patent covers Directa Plus’ ‘elastomeric composition comprising graphene and tyre components’.

I know graphene is a "buzz" product, likely to be overhyped. However, I am glad to hear that there is a product that will be using graphene, because industrial-scale production will quickly lead to the price and availability coming down to sane levels. Then, there will be experimentation with a product of reliable and consistent quality.

I'm sure that whatever carbon product that they will be putting into these tires will have other uses. Whether or not it is "true" graphene...I don't care. If its even close to being four layers thick, and also affordable...it will spur a burst of new applications, so we can see what it is useful for. Not in theory, in the real world.

If a new wonder battery claims to have three times the energy density of modern lithium cells, but...it only really has twice the density?...It is still a good thing.

Until we better understand the health risks of graphene exposure, it seems like gross negligence to put it in a product that is designed to shed its material into the human environment.

Molecularly, this stuff is much gnarlier than asbestos. Think free-floating razor blades to asbestos's sharpened fence posts. I don't like to contemplate what it does to DNA.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.

I see where graphene might make a puncture proof tire if it's in the cord, but traction? Counter intuitive. Sounds like vaporware. Let's see what kind of investment money can be lured by talk of graphene, sexy graphene.

Hehe... ESB "Search found 965 matches: Graphene"... again:

Mass production of Graphene moves a step closer with “cost effective” breakthrough :
https://cyclingindustry.news/mass-produ ... akthrough/

Starts:
A Singapore research team has developed a new Graphene production method that requires 50 times less solvent than traditional methods and one that opens the door to larger-scale production.

Pioneered by a team at the National University Singapore, the team set about creating a more sustainable method to harvest what has been dubbed a wonder material by many.

Pioneer Vittoria Explains Graphene Tyre Technology:
https://www.bike-eu.com/sales-trends/ni ... y-10133901

Starts:
MADONE, Italy – In the past five years Vittoria has been working intensively on the integration of wonder material Graphene in the rubber of its tyres. That proved to be a bigger challenge than expected. However, with more and more ‘Graphene-tyres’ being introduced by Vittoria that now also uses the exceptional characteristics of the material for carbon rims, that challenge seems to be overcome. Reason for Vittoria to explain more on Graphene.
Includes:
200 times stronger than steel
:mrgreen:

... and:
Moreover, one of the key findings was that Graphene-enhanced carbon wheels for tubeless tyres are now able to be used at higher air pressures and experience enhanced braking in all conditions.”

Yep. Treated walnuts shells. Not sure if the tire is also made stronger tho.

A few years back I did some investigation into rubber formulations while considering having some table tennis rubber made. Apparently additives and fillers are super important in determining rubber characteristics.
