Nice idea, I hadn’t thought of that. I’m constantly on the look out for a pair of 2.5 zmax. If I find them they could have a home here.I would swap the tires but that´s entirely dictated by the terrain i ride. I would use all the extra clearance provided by the yo and fit 2.4 tires front and back; it was one of the first bikes to allow 2.5 tires.
