ATV foam-filled tyres

Hi All, I am a rubber technologist who likes developing things. I am also gaining an interest in small-scale farming with the view to becoming self-sufficient in future. My question is as follows: are there perhaps regular problems regarding flat tyres on farming ATVs? Would the development of a lightweight, maintenance-free foam-filling system that would provide the necessary cushioning and load-carrying characteristics of air-filled tyres be of any benefit? Any comments or opinions would be much appreciated. Thank you Daniel Honiball

Hi Daniel,

So far, so good, I haven't had a flat on my Quad bike, that I ride almost every day. It may be a product worthwhile developing. Sounds like a great idea, Good luck with it.

Cheers,

Barb

Hi Daniel,

Welcome to the forum.

What a great idea, I used to spend so much time fixing holes in ATV bike tyres and there is nothing worse than a flat tyre when you are 10km from home and have a load on. We would use the rubber plugs, which involved running water over the tyre to firstly find the hole, once the hole was plugged up it would often still have a slow leak around it and you would then have to try and plug it again or get a new set of tyres.

We made the mistake of buying an ATV with standard 2 ply rated tyres, never again. The next set we purchased were 6 ply, which were better however after some wear and tear they still seemed very prone to punchers.

Let us all know how the idea develops, price of the tyre will be a big factor.

Charlie

Reckon you would be on a winner there Daniel. Nothing pees you off so much as being in the middle of nowhere on your quad, all loaded up, tired from a day's work and you have a flat. Its a LONG walk home and no fun at all.

When i was a kid we had an old HK ute wieghed a "Ton"(not tonne) and its tyres always bothered me when we collected wood or freighted anything heavy.

One the worries i wondered was its tyres because they are so narrow on that stock model of it. The main problem being side thrust, the walls collapse more easily but yet they did live their expectancy to treadless.

What i wondered was not about ATV(counts to safety also) tyres needing a foam internal , but was about the bearings in carrying a load only 300Km and the rear bearings need replacement and the danger and need for foam and internal support in these narrow tyres on an HK when turning and curve handling, all in all a good machine but side thrust decreases as much as no puncture would be good with a heavy Maximum load the tyres do not want to be deflated or have side thrust collapse problems.

The best i came up(as an idea) with was a mixture of rubber foam very close to the plastic rubber of tyres itself and a type of internal solid rubber strut set running from top to lower mid wall from either side and a heavier solid rubber top wall grabbing under the rim to mount these crossing solid rubber struts through the foam that extended around a quarter of the way out under the rim toward outer circumfrence.

The only limitation becomes a heavy tyre, and difficult to balance, but negligable in load carrying at Max weight over the back axles.

Many thanks for your comments folks! I have begun development of the 25x10-12 (rear) and 25x8-12 (front) sizes and will be trialling them within the next few weeks. @ nicephotog: I have actually developed a rubber foam filled tyre (size 7.50-16) for underground mining Landcruisers. It is restricted to 40 kph for safety reasons, but doesn't have balance issues and has been tested to much higher speeds. I expect to have it commercialised during 2014. Daniel Honiball
