Hi Tomaz,
OK, the ideal setup then would be the 2.5"/50mm lift, that is the most
common.
I had 285/75/16s BFG ATs, I wouldn't want to go much bigger because it
will affect the speedo, gearing, etc.
I am still debating whether 285 is too wide, I certainly had to air down
more on sand than Lio who had 235/85/16s (about the same diameter) and the
235s are a more popular size in Africa.
Lio also thought they would be better for fuel consumption on tarmac due
to the lower surface area, but I've not had time to investigate things
further.
The 235s are about 28mm narrower in diameter, so he lost 14mm on height.
You can play around with tyre sizes at

Having said that, I have always fancied the BFG Traction tyres that are a
compromise tyre between AT and MT that only come in the 235/85 size.
Also bear in mind the following when looking at OME setups:
The springs and shocks are rated for different loads - make sure you have
the right ones for the loads you are carrying (I have a chart somewhere if
you want a copy).
The OME springs are longer on one side than the other - this is to cater
for the extreme camber on the roads in Aus to deal with the heavy rains.
In Aus driving on the left hand side as we do in the UK, they advise to
put the longer spring on the passenger side (LHS) to counter the camber,
however in the UK we don't have so much camber so I always advise having
the longer spring on the drivers side to counter the weight of the driver
(I have seen the size of some of you ;-)
Putting the longer springs on the drivers side (RHS) helps in Europe and
more importantly in places like Morocco where they do have more camber.
My 80 already had the springs on it when I got it and they have set it up
the Aus (wrong) way - I don't notice it much in the UK, but when in
Morocco I definitely felt that I was driving at an angle, which wasn't fun
when you see the states of their roads.
If you are in Europe and have a Left hand drive vehicle, put the longer
springs on the passenger (RHS) side.
Depending on your loading it will put more stress on things like the UJs
on the propshafts and you will also need to consider having adjustable
panhard rods to compensate fort the lift, unfortunately this is an area I
haven't looked into much.
