Thread: not your normal tyre question

Geesh, this could be a blood fued to outdo the Civil War in America. Good luck mate!!

Sand tyres. Tall, fat and very very open pattern are the best.

These are sand tyres
Sand Tires Catalog

Two words - formula offroad

Google Pics Formula Offroad

Even better youtube search it!

But I doubt those tyres are really feasible.......... but it would look cool and you did say ANYthing haha

I suppose you already know the basics about sand tyres, and that a datto 180b got over big red with no dramas........

And (pics) if it actually happens!!!!!!!!!!

pics will be mandatory, and it is in the sand hills of Coffin Bay the biggest softest sand hills in Australia

I did the Simpson East West in a sewing machine engine powered SIII with 7.50x16 truck steer tyres.

A non aggressive tread will lay out a track without digging in.

A tall tyre will have less rolling resistance, but too tall and you won't be able to take off in the sand.

Go too fat, and you will have more resistance to overcome. Imagine a tank (long narrow footprint) vs a steam roller (fat wide footprint). What you want to do is cover a large foot print, but with a narrow front band of resistance.

A gentle throttle on take off so you don't break ground and dig in.

Low pressures will be your greatest asset. I'll give a 7.50R16 as an example.
If you deflate it from 50psi to 15psi you will increase the footprint by 44%, but the footprint will remain at the same width, although the side wall may bulge a bit. To prove it to yourself, lower a tyre on some foam (like a closed cell foam old school type camping/sleeping mat). It will leave an imprint. Mark the corners with a texta, then lower the tyre pressure and repeat the test. You'll notice that the new imprint is longer, but not wider. The lower the tyre pressure, the longer the footprint. I read an article or saw a DVD about the recovery guy in Birdsville, and he was able to tow broken down cars over dunes by lowering pressures to as little as 12psi.

the best sand tyres are bald tyres.......


to reduce down pressure.....wider and taller tyres at lower pressures will get you over the sand.......

if you are comparing to a suzuki sierra......any tyres on them will work well on sand because the cars are so light.......

tall rag construction steer tyres are the best in sand. Id suggest that bead lockers that allow you to seriously drop the tyre pressure.

so are the nose wheels from aircraft.

go take your pick of almost any HT tyre that fits and your laughing.

I'll get a pic of the tread pattern from my beach rubber if you really want.

actually a set of Mattracks will out do most normal tyres

spend some money on less sizable tyres and get some internal bead locks that way you can let your pressures right down!! and then nothing will stop you
