I'd taken a look at those and a few of the other px/on-one sets but wasn't sure about the range of tyre sizes they take. They say 25mm width, I assume external, but no real idea of what they can take, if they start at 28c that should be fine.
Seeing as people have been racing cross on narrow rims since forever I'm sure that a rim with an external width of 25 will be absolutely fine with anything up to 32-35.
