i don't think the ramped teeth are a problem as long as the chain is straight and tight.

42x15 is gonna be a little tougher on that thing than it is with skinny tires. obviously, ride what's comfortable. but remember with the softer tires, more rolling resistance from the knobs and greater wheel diameter you're going to notice a difference.
