Thread: help, need Perentie rim/tyre combo for sand

9.00x16 tyres on a 7" rim would be an improvement! Though you want something with a lower sidewall rating than a truck tyre would typically have.
Look towards agricultural tyres perhaps.

I run 285/75x16s on 7" wide disco 1 steel rims. Running them on 7 psi I haven't yet been in a situation I couldn't drive out of. I have recovered a few people too.

I once got bogged retrieving my 5m plate dory on a fairly steep beach, but just unhooked, drove out and snatched the boat and trailer up onto the flat with a strap.

You can always go bigger, but you will need a suspension lift first.

Is this with standard offset and no lift?

In my experience, wider tyres are not better on sand than narrow tyres. Wide tyres have greater resistance and will be harder for the vehicle to push. Narrow tyres have a nice long footprint in sand. What ply rating are your tyres? If the side walls dont flex when you deflate (like with 12 plytruck tyres for example) you'll get bogged every time.

No lift. The rims have an extra 30 mm offset over std. Std rims would fit but rub on the rear coil turrets on articulation.

Any wider tire is better then the Olympic Steel Treks. The Steel Treks do an excellent job of cutting into the sand even at low PSI.

Well that's the issue then. The tyre size is spot on. The tyres are not.

Olympic steel treks have too stiff a sidewall. It is not that they are the wrong size.

Not this argument again...

This myth is caused by people swapping their 16s for 15's that are wider but smaller in diameter.

The best option is a tyre that gives you both a long footprint (large diameter) but also maximises total area in contact with the ground to reduce ground pressure in soft sand.

Drive on some WA beaches with 7.50s and you will sink straight to the axles whatever pressure you are running. Yet the same vehicle on 35x13.5s will float right over the top.
