I have (err...sorry "had"
) the Maxxis Buckshot Mudder 245/75/16's on my WJ with the 2" OME kit. I know of the same size tyre going under standard suspension...but it depends how sagged it is. My rear suspension was so shagged that with the 40mm OME lift, I got a 75mm lift on the driver's side...but that's not what you're asking
so I hope this helps a bit anyway.
