A 2.4 would be fine on 25mm.
I've been around the houses of wheel and tyre size, but I'm back where I was a decade ago with 2.4 front and rear.
Chisel came with 25mm rim and 2.4 fast tracks. Insert made it feel nicer, less bouncy.
... then I dented the rim and bought some 30mm wide Deore XT wheels. Still on 2.4s.
