I just bought almost indestructible Deutscher slasher- mower and very happy with performance while slashing bushes.Until today I caught flat 2km of the home
I heard that we could easily fill the tire with some sealant, foam to make it flat-proof?

What sort of sealant we could use to fill mower tires, wheelbarrow etc?
I heard that can not use ordinary polyurethane foam, because it expands too much.
What product on our Aussie market suits?
This tire is relatively small approx 20-30 cm diameter.

Just buy a solid tyre for the thing and be done with it. Great mower thou

As he said, buy solids. Been using them on forklifts for years

If you desperately wanted to flat proof your tyre, you could do what we do with mountain bikes and convert the tyre to tubeless. This involves specific valves, rim tape and something like Stans sealant. But to be honest, just do what the others say as if would not be worth the hassle....go for solids.

OK, I will look for solid tire 3.5 x 6.0 somewhere.
Where to look? In the meantime, I need to come back with slasher 2km trough the bushes tomorrow.
Hopefully, DUCK TAPE will hold!!!


I have been thinking initially about eventually filling the tube with a sealant to convert the whole wheel into solid,

wet cement

Just use the green "Slime" tyre sealant from Super Cheap Auto or Repco.

Nothing is perfect and nothing will be 100% puncture proof, but it works better than nothing.

You can still put patches on a tube with slime in if you have to.

Then buy a couple of spare tubes, they are fairly cheap.

Other than a 2km walk (which presumably you'd have to do anyway) once you have changed a tube a few times it takes but a few minutes.


oh - and keep the tyres pumped up, maximum pressure allowed on the side wall.



Wait until you get a puncture on a 320/18-24 water filled tractor tyre in the bottom of a gully 2km from anywhere.

Get a smaller garden

Duct tape ..... not DUCK TAPE
Office worker I'm guessing

Go to your closest hardware store and buy heaps of tubes of the cheapest silastic. Take the wheel off, take the valve out drill a hole in the tyre at each end and fill the tyre.

Don't go solids, rough ride and you'll get bogged everywhere. I reckon the slime or cut up a truck tube to make some liners.

Could try filling the tyre with squash balls or tennis balls or something similar. They may Destroy themselves in the tyre after some time though.
Have heard of mowing contractors using the "green slime" because of continually getting puntures.

I think in reality Macro is just preparing for a drive to the Margret River region.

both equally valid as it was originally called duck tape when invented

I'd run with duct though as it decribes the most common usage

So I did arrived today to left overnight Deutscher with duct taped tire only to find out that other one is flat too,
So another walk 2km to get more duck/t tape.Eventually everything works like dream, I managed to work whole day, slashing and pumping a bit from time to time.Duck tape saved a day.In long term tires MUST be flat proofed either by slime or sealant to make it solid.
I found 3 holes in single tube made by pieces of old barbed wire.

get your hans on some older tyres ,cut off sidewall ,deflate tyre and force fit old skins over top then pump up. i reckon a slasher working scrub is gonna get some big holes that slime will never quite fix. also try leaving old tubes inside tyre as a a line for the new tubes.
this is my specialist skill Landyacht knows these things

Be aware that when you slash scrub, you end up with a paddock covered in the upright stems of whatever you slash. After a few weeks the stems dry out and get super strong so that if you drive over the slashed area, or ride over it with a motor bike you end up with punctured tyres.
This lasts for two or three years until the sticks rot or get eaten by white ants.. It can even puncture the side walls of tractor tyres.
It's ok if you intend to plough or scrape it straight away but otherwise slashing it comes with later consequences.
It's ok on light grassy weeds or arum lillies or anything soft but that's all. Tea tree scrub,? definitely not.

That's why you see combine harvesters and self propelled swathers with big pieces of conveyor rubber attached to the comb to stagtegicly lay the stubble down in front of the tyres,,, stubble erosion on farm machinery tyres is incredible

I have been thinking about other option to.
What about some liner inside tyre?
I can remove tube for w while and lay something inside tire.
Piece of another tire, kevlar tape ? Something that make tire thicker from inside, to protect tube.

I think Landyacht already gave you that answer.

Yep, I discovered the same and read Landyach already knows and do this for years.
But I have also another idea.
Filling with silicone from Bunnings.
Could be expensive even for this small 6" tire.
$6 per cheapest silicone tube 330 mln
But I could try to fill the space inside with something first.
Golf balls? glass beads ,plastic granules, even stones and gravel?
Then amount of silicone is greatly reduced.
Ideal could be 2 component mix- like liquid rubber , that will set permanently and evenly.

looks like technology is here to do so professionally,
Price is $66+gst per one 6 x 3.5" tire.

but here is example how NOT TO DO IT

Oh come on! You have invented spiral wound fuel tanks and tunnels. Surely you can invent a flatproof tyre that is cheaper than that and can be done in ten minutes?
