Tyres with only tread and no sidewalls?

Probably.....

Arh, it would appear that it is going to be one.

But the shed looked nice...

Can we get this thread back on track?

Doh, where is the designated wood storage section.

No as good as I'd hoped.

I've started off with something basic so as not to intimidate others. I bet there's some serious shed porn on PH.

I don't see these being a hit.

Effectively, they are like run-flat tyres but with the sidewalls mounted at 90-degrees.

I can imagine the ride quality being poor with no air in them, they must be difficult to install, and they are unlikely to be very aero-efficient.

Which is a shame, because they look cool.

You could produce them with different radial stiffness properties i suppose, for different load ratings. Transverse stiffness will be mega, when in use, theyd load up and wear more evenly.

Several down sides though, obviously. Getting stuff stuck in them, fitting, the fact you'd need different wheels (probably) cost, i'm quite sure, etc.

Wonder if they can be re-tread. Probably.

Imagine what would happen under acceleration or braking... they'd twist-up like drag tyres.

They'd become seriously unbalanced with dried mud inside them, surely?

Those tyres have been around as a prototype for years

One of my first thoughts, along with other stuff and the need for new wheels, etc.

I can see the use for them in slower applications, looking into it for a whole 30 seconds earlier suggested that they are being trialed on things like Segways and so on, before moving onwards. As such I can see the benefits of their use there.

As tyres for road cars, not so sure. In the real World there are many issues which could easily arise, not the least of which they appear inviting to those who might wish to put others in harms way...

On the other side you could fit those beaddy clicky things like children used to have on the spokes of their bikes

Just to contradict those saying the flaws are the open "spokes" of the tyres, I believe the intention was to add a soft sidewall just to protect from the sort of problems mentioned but not to add any particular stiffness (unlike current tyres) unless required.

They left them off for the pictures so you could see the spokes because otherwise it would just look like any other tyre

[sinizter]

The open sides are only to demo the technology - not for release - so there will be no mud/stones stuck inside.

I imagine the ride would be harder than current run flat tyres - We know how popular they are around here.

[Alfanatic]

The ones I've seen photos of all look to be dimensionally equivalent to high profile tyres, which would mean smaller diameter wheels, which would mean smaller brake discs on high performance cars. No idea if they have to be that high profile or not.

Man you want to see the calendar I've got at home. Shed porn? Shed FILTH. I'll snap a couple later for ya.
