Outer Limits 4x4 Board

i understand a bit of maths would be involved.it would be like 4x4 tractor...do you think the wider tyre at the back would try to follow the front rut and have more bite on side lugs in mud..sand might be differant story. or would it work better same track, same tyre width...being a ute it seems easy way of keeping car low with added traction,larger pushing footprint...like the older syle offroad race buggies..plus would like to see what it looks like.

i ran 40s on the rear of my truggy with 37s on the front for a bit. 4.5r+p in the front 4.88 in the rear, maths all worked out but it still felt funny, didnt like how the rear steer felt. it also made step ups steeper, the leading edge of the rear tyre made contact with the ledge 1.5"s before it would have with the 37s. made the car sit on quite a bit more of an angle.
But if you built the car with these things in mind with a touch more wheelbase and lower in the rear it would work fine
