Which gen Iron Cross? I've never installed one of those that didn't leave me hating being alive.
I was a pretty early adopter of IC, so probably gen 1. I have some Grails which I could try, but I don't really want to dismount the Schwalbe Ones that are on them.
I've put a fair few tyres on ICs and never had a problem, but they have been a mix of regular CX tyres converted to tubeless and schwalbe tubeless specific stuff, not vittoria.
I've never had tyre fitting issues, but Corsa Speeds have seen me kill tubes, levers and nearly myself on my Jet+. I think Vittoria have gone for the tighter end of bead diameters.
