The climate change debate continues.

The problem is the tyre disposal fee system is only administered by tyre shops - who take their used tyres to tyre recyclers. But a lot of people don't buy new tyres from tyre shops, they buy good used tyres from private sellers, fit them themselves - then have to dispose of the old tyres. So their solution is simply to dump the used tyres. It costs around $10 to send a used passenger tyre to a tyre recycler, about $12 for a 4WD tyre, and around $20 for a small truck tyre. We need a better used tyre disposal system that encourages the tyre dumpers to drop their tyres at a recycling point.

They need to increase the fines for tyre dumping.

They can do that.. but they have to be bothered catching the cretins.

Used tyres can be made into walls for dwellings. They are hard to fill though.

 

Personally, I would live in a house with the exterior walls made from old tyres filled with sand. The University of SA has tried tyres out for retaining walls and they are good for this too.

 

[Bruce Tuncks]

If you burn them, I was told it had better be at night or the black smoke might give the game away. I don't advise burning them anyway.

[spacesailor]

TYRE BURNING !

But ! , even Coal is black smoke producing. until it is crushed then injected at the right mix , just the same as petrol  ¬! .

 

Paris is burning ' rubbish ' , no one there complains .

After I’d used them to protect my newly-planted trees, I carried 400 tyres up my hill and used them as a retaining wall. The hard part was filling them; two steel buckets of rocks per tyre, gathered by hand and carried up the hill. That terrace will outlast me, as long as I protect it from wildfires.

If a fire takes hold in a tyre, you’d never put it out.

[Bruce Tuncks]

Thanks Old K. I never thought about a fire setting the tyres alight, but you are right! 

[onetrack]

Using tyres for reinforcement or fill is banned here in the West. You cannot store more than 100 tyre carcasses without a Dangerous Goods licence, such is their flammability.

Tyres used for soil reinforcement gradually leach toxic compounds such as heavy metals, and other chemical compounds (including oil) into the soil, making it unsafe for growing fruit and vegetables.

You cannot even transport more than 250kg of tyres here without a DG licence, such is the concern of the EPA.

Quite a few years ago, I read about a house in the U.S. built with tyres for walls. From memory, I think it was in semi arid southern California. It was a semi dugout. The side of a dune or embankment was excavated out and a concrete floor poured. Load bearing walls were concrete, but all others were overlapped tyres. They were steel reinforced with concrete fill, much the same as a Bessa block wall if you had every block concrete filled with steel rods. The roof was a concrete suspended slab construction, with the natural dirt replaced on top. The tyre walls were all adobe plastered to finish it off.

 

 To be able to fill the tyre walls fully, I recon you'd need a concrete pump with a fairly wet mix to flow into the tyre side walls. The only externally exposed part of the house was the front, mainly glass. Very similar to some dugouts in Coober Pedy (the flasher ones).

It used to be fairly common to saw tractor tyres in half to make round feeder troughs for livestock. Obviously they have to be rag tyres, but I don't know if they still make rag tyres in tractor sizes.

[onetrack]

Yes, rag (crossply) tyres are still produced in sizeable numbers. Not everyone sees the benefit of radials, and in some cases rag tyres provide a heavier wall strength which deflects stakes and stones and stumps better, thus reducing the number of flats.

Back in the days of the Nickel boom when lease pegging was going ballistic, and whole teams of blokes were doing pegging, the pegging teams usually used Landrovers for "bush-bashing" the grid lines in. This meant driving straight through the scrub to acquire a pegging line.

The Landrovers copped a hammering, but the tyres copped the worst hammering, from stakes from broken-off limbs, and mallee trunks and stumps. The peggers would end up using bald rag tyres on the Landrovers, as these provided the maximum resistance to stakes.

The bald treads stopped stakes getting a guideline into the tyre carcass, and the heavy rag walls resisted stakes far better than radial walls.

I've never had anything to do with Nickel apart from doing an access track into a lease near Hall's Creek. Just curious how they look for it; I'd assume they use a truck mounted rig to take core samples.

Stiffer sidewalls seem to be the main difference of the new “low friction” tyres used on some Electric Vehicles to acheive a few extra km range.

Willie - Yes, drilling in a grid pattern is the way it's done. They utilise diamond drilling, as the nickel is found in the sulfide ground, which is not usually found until you get down to around 50M to 150M into the ground. The material found between the surface and the sulfide ground is called the oxidised ground, it has been severely weathered. However, sometimes the sulfide ground is found on the surface.

The sulfide ground is usually extremely hard, so only diamond drills will penetrate it.

Electric cars have high preasure 80 psi , in their tyres .

So my neibour tells me .

spacesailor

[facthunter]

I wouldn't be surprised if some do space. So do early beaded edge car and motorcycle tyres The high pressure keeps the tyre in the bead of the rim. There's no steel  wire..  Nev

[octave]

I dont know about other EVs but Tesla uses 40-45 PSI.  

[spacesailor]

My neibours is a Tesla 3 , & when I asked about his tyres having no bulge,  he said 80 psi .

Done by the dealer each time he drops it off .

spacesailor

[octave]

Your neigbour may be using non standard tyres but the factory fitted tyres take 42-45 psi

 

Tesla Model 3 Tire Pressure

• Typical recommended cold pressure: 42-45 psi (42 psi recommended, lower for ride comfort, higher for a small addition to range)
• TPMS: Conventional 433mhz pressure sensors (2018-2021, pre-refresh), or Tesla proprietary Bluetooth sensors (2021-present, post-refresh)

How to Check Model 3 Tire Pressure (TPMS): Using your main touchscreen, swipe cards (left side of the screen) until the tire pressure visualization displays for all four wheels (either in psi or bar). Alternatively, use the menu to go to Controls > Service.

[spacesailor]

YES

He  checked that screen & the preasure sensors said " OK "  . Thats when he said 80 psi .

Should I tell him to recheck ? .

spacesailor

 

[Bruce Tuncks]

yes, space, tell him to recheck everything he thinks is true.

[kgwilson]

Modern tyres only have about 19% natural rubber in them & 24% synthetic polymers. The rest is steel 12%, textiles 4%, fillers like carbon black & silica 26%, curing systems (sulfur & zinc oxide) , antioxidants & antiozonants 14%. All up they seem pretty toxic to me.

[Bruce Tuncks]

80 psi is way too much for any car tyre I have ever heard of. Anything over 50 psi is a lot. I agree with the handbook pressures and recommend that he drive to just about any service station and check the pressure physically.
