The airless tyre - Trilogy

Throw away your jacks, spares and puncture repair kits.

The future is here.

It’s called the ‘airless’ tyre and if you fit it to your car – which you’ll be able to by the start of next year – you’ll never get a puncture again. Ever.

Originally designed for the US military by off-road specialists Polaris, these ‘airless’ tyres will be put on the market in early 2014.

Sounds great doesn’t it? But we can already hear the question in your mind: what do they ride like?

Runflat tyres are notoriously rough on the road, so it’d be easy to assume this ‘airless’ rubber would be even worse.

Not so, says Polaris.

The company claims its new rubber is actually smoother over rough terrain and is quieter than its air-filled rivals.

Apparently they don’t ‘hum and drum’ like a conventional tyre.

Polaris also claims the new rubber has been put through ‘military grade testing’.

They have withstood gunshots and been driven on for hundreds of hours and thousands of kilometres.

This has been around a long time. Google Tweel.

Punctures mean profits so why would manufacturers bother?

Thank god because that constant machine gun fire on my route to work is becoming tiring.

Like daveyjp said, they've been around for years - without success.

I recall trying a pushbike in the '70s with airless tyres. It had all the comfort of a solid rubber tyre and the drag of a half inflated one.

Talk about a solution in search of a problem. Pneumatic tyres are superb in almost every respect.

Have they tested these at higher speeds than quadbikes can attain? The NVH and aero drag of that flexing honeycomb look pretty poor to me. They look cool though. In the same way that a snapped in half looks cool. Then you just eat it.

Popular Science, about 1930. A wheel made of hickory and rubber with flexible spokes. Claimed to replace suspension springs, and resist damage and blowouts.

Wouldn't an ordinary tyre full of sponge work much better?

Is it not the case that pneumatic tyres can generate predictable slip angles/cornering force, whereas these airless gadgets are really just 'sprung' solid tyres.

Ok for off-road but how do they cope with curves at speed?

Good for use in rundown areas and outside nightclubs. I wonder how long the tread would last as well?

Good for things like ride-on mowers and wheelbarrows. On a car, I reserve judgement until they are tested for more than "hundreds of hours and thousands of kilometers"!

What if you get a stone or something lodged in one of the honeycomb bits, putting the wheel out of balance, and end up with severe wheel wobble at 60 mph on the motorway and then the stone flies out and hits another vehicle?

Can see all cars having these in 3-4 years time. Well, many new cars anyway.

Polaris aims to launch its airless tyres in 2014

11 March 2013

More details have been revealed about how Polaris is planning to launch its innovative airless tyres for the public to experience and enjoy.

In effect, such a concept could make the concern among drivers that their car could suffer a flat tyre while taking part in a long road trip, especially over tricky road conditions, a thing of the past.

This is because Polaris’ unique tyre is designed with a honeycomb-style web of hexagon-shaped partitioned rubber, which acts as the product’s core and prevents it from collapsing no matter the terrain driven over.

Joaquin Salas, the business development representative of Polaris, also acknowledged to Fox News that the tyres are designed to offer a smoother ride over bumps in the road, as well as being quieter in operation when put in contrast to the specifications of a standard tyre.

"There is nowhere for the sound to pool, so there’s no humming or drumming like there is with a standard pneumatic tyre,” Mr Salas underlined to the news portal.

Motorists should not feel concerned that the airless tyres will be instantly recognisable when out on the road though, as industry experts have been reported by the Herald Sun as saying that the products will likely come complete with sidewalls and look just like a normal set of tyres to the naked eye.

On top of all of this, the airless tyres are effectively bulletproof and road-spike proof - two reasons why Resilient Technologies, the original developer of the products, initially designed the tyres for military and off-road buggy use.

Following its recent acquisition of Resilient Technologies though, Polaris became encouraged by the validation testing of the technology and began to pursue how the tyres could be made available for wider production in the near future.

Wisconsin inventor Ali Manesh, who was the original owner of Resilient Technologies, pointed out that one of the main reasons why he agreed to sell his business to Polaris is so that his firm’s airless tyres could finally enter the mass market.

"We developed the idea, had a design and proved that it worked. But we could not take it into full production," Mr Manesh pointed out to the Star Tribune newspaper.

"So Polaris took it from there. I am grateful because that is my baby. I am glad that somebody grew it."

The concept of airless tyres has been discussed on various occasions over the past decade, though the technology has never made its way to the public market to date.

In 2005, for example, well-known French tyre maker Michelin became the first company in the motoring industry to show off the idea of an airless tyre. A few years later in 2011, Japan manufacturer Bridgestone officially announced that it was looking into how to mass produce these state-of-the-art products.

However, Polaris, which is commonly known as being an American-based manufacturer of all-terrain vehicles, is confident that its acquisition of Resilient Technologies should mean that it will have airless tyres on the market ready to purchase by the end of next year.

ATS Euromaster stocks the latest tyres to hit the market at very affordable prices.

"There is nowhere for the sound to pool, so there’s no humming or drumming like there is with a standard pneumatic tyre,” Mr Salas underlined to the news portal.

This is bull. It is largely the flexing of the tread paatern that is responsible for tyre noise. So unless the airless tyre is rigid or treadless, it won't be any quieter than a conventional tyre.

This product is desparately looking for a raison d'etre. I can pretty much guarentee that you won't see it in ATS euromaster next year-or the year after.
