Have a look at tuff truck and the like , even if that's not your flavour you won't do it on small tyres. Think of a skateboard mounting a kerb versus a mountain bike , overall diameter is the key

One of the most competent trucks at tuff truck is the portaled Bush Ranger and it runs 39.5's when most of the other big rigs are between running tyres between 40 and 50 inch's.

I didn't think D3/4's would go much bigger than a 32 because of the chassis Xmember being in the way.

39.5 compared to 40 and some 50 inch are we splitting rabbits?

Just funny pretty much the smallest tyred truck is the most capable

I have 32.3" on my D4 and get the occassional rub, the vehicle needs to have the GOE EAS or LIAMS or it will rub on lock.

AND in the event of failure will stop with the wheels touching the top of the arches. Just something to be wary of..

What's your wheel/tyre size?

My guess is 285/65 R18, not legal in NSW though (827.7mm OA) . 275/65 R18 manages to fit in the laws (814.7mm OA).

The 285 is 7.8% larger than the standard tyre while the 275 is 6.33% which gets under the 7% rule in NSW.
