What tyre size have you been using? In my experience putting a tyre only a few mm wider than the rim width is horrible in setting up.. So I wouldn't think a 35mm will work on a Blunt.
Depends on tyre. Been thinking a lot about this recently with the popularity of + tyres. I wouldn't fit a tyre to a rim that was more than 45-55% of the tyre's width. Particularly for long distance.
