I'm basing the tire size off the
Sheldon Brown Tire Sizing guide, which lists anything up to a 25mm tire as safe on a 13mm inner dimension rim. A 35mm tire shouldn't go on anything less than a 17mm I.D. according to his charts.
The risk you run with a super wide tire on a very narrow rim is poor locking of the tire bead along the rim hook, which could blow the tire off the rim. Another risk is sidewall rolling, which could also unseat the bead.
No way do I want to imply that Sheldon was wrong when he wrote that, but my Raleigh One way comes with AT400 rims, which have the same sizing as the AT450. The Raleigh comes stock with Vittoria Randonneur Cross in 700x35c. I find it hard to beleive that major bike manufacturers would use a combo tire/rim that sets them up for recalls/lawsuits.
