I'm thinking that versawheels with blue nitrile might have a large enough OD to give a decent amount of rock with 4" Colson wheels on the outside.

Alternatively, you could use 4" wheels on the back and middle and a 3.5" wheel on the front. That gives you the same amount of rock as a 1/8" center drop.
There's definitely a lot you can do with the wheels, I'm just a huge fan of the durability of Colson wheels and we have a lathe handy right in our workshop.

I've had a few extra requests for the CAD model, so here it is.
