I can't read Sheldon's mind, but you are probably in that gray area between "recommended" and "will it work".
I am not an expert, but I suspect with a tire that wide you are probably limited on the air pressure by the tire manufacturer. I would be extremely cautious about tire pressure... Too much and you could blow the tire off of the rim due to the increased angle between the sidewall and the rim. Too little, and I would fear instability, pinch flats or both.
