it's awesome to see another one of these! i'd love more pictures at some point if you're able and willing.
right now i'm leaning towards the rene herse rat trap pass tires and they're 2.3", but at $70 a pop i'm still kinda shopping around. this bike will see probably 70/30 pavement/off road, so i want something that can handle both ok, but i also want as high volume as i can go.
