That's what I think too.
At 4'11" you're going to be hard to fit. If you want to be comfortable, you need to find a good fitter. Somebody local, who knows your local riding conditions would be best.
Are you sure you need knobby tires? Unless you're riding some pretty extream conditions, I think that knobby bicycle tires are over rated.
