Ron has been scarce around here the past few months, don't know why, but don't be insulted if you don't get a reply. Very knowledgeable guy though on this subject.
I think those are 406 wheels. Ron favors big cushy tires, so I'm pretty sure those tires are at least 2.0" section, possibly a bit greater.
