The Pro-one tires are tubeless ready and for this have an additional air tightness layer. With an inner tube you will add the rolling resistance of the tube to the one of the tubeless layer.

What is the inner width of your rims? Its often possible to use wider tires than written in the ETRTO recommendation.
