I researched my options pretty well (even going through a set of rims) that were not right- would have required a 50mm wheel spacer for the van (perfect fit on the triton but not worth the risk).
Anyway got a set of Goodyear kevlar MTR 235/85/16 tyres cheep on ebay (brand new...)
needed a set of rims, these needed to be rated at 1100kg (van is a single axle 2 tonne offroader) and zero offset, so not much choice.

Got some CSA rims in 16x 7 0 offset

load rating of tyres more than adequate

Fitted they don't look much in white- but has to match the van not the truck, missed the brake calliper (couldn't get a photo of the clearance but would say less than 5mm.

very hard to photograph, but this combination does not stick out past the guards, increase in track.

don't mind the mess.

slightly bigger than the 265/70/17 I run normally, but the 265's also have 20,000kms.
measured 806mm for the new 235's and 802mm for the 265's (still 11-12mm tread remains on the 265's down from 14mm)
I also tried one of the original van rims and tyres and can confirm 15" rims in a zero offset will foul the brakes.

checked out the back of a mitsubishi alloy and you can just make out what we already know.
17x7 rim JJ +38 offset (sorry for the crap pic)
Hope this is of help to someone.
BTW- Nissan patrols run zero offset rims
