Stooge MK2 rear rim & tyre recommendation

[Huwblut]

Evening

I’ve just picked up a Stooge MK2 frame

I already have a couple of Rabbit Holes / Chronicles one of which will go up front but I’m under the impression that I’ll need something less wide for the rear.

Suggestions for rim / tyre combo with plenty of mud clearance appreciated.

Cheers
