I've tried Big Apples on my crosscheck, they barely fit but were a nice ride. My teenage son had BAs on his MTB converted to touring bike- they rode well and were nice on limestone trails.
IMHO- 47 or 42 mm regular Schwalbe Marathons not only fit better but were better suited to a mix of road, dirt, sand surfaces encountered during a commute. The 42 mm size is especially effective, have about 5000 km on the current set, still going well.
