Before swapping tires, I would contact Yan to get some insight. According to the DT website, the Nova comes with 1.2 narrow tires so I'm wondering if this means the rims will only take narrow tires. I'm sure you can use wider tires, but the question is "how wide"? The Big Apples may be out of the question.

Glad to hear that the M-Wave only gives occasional heel strike in "extreme" situations. As I said before, this rack is half the price of the Versarack, making it a killer deal.

Now all you need is a nice set of fenders ; )
