I think I'm going to go with a set of 255/40 RT615k+ to start.
A 9" wheel offset will depend on the spring OD, lower spring perch OD and location in relation to the top and/or section width of the tyre. Lower spring perch location is dictated by ride height.

Wheel offset advice from others is only useful if they're running the same setup as you. Your best option is to measure yourself... and them measure it again.. at least twice more. I use correct offset wheels rather than using spacers.

You'll need to run a 255/35 (not 255/40, which will be far too tall).
