Tires for my hybrid

[jjmolyet]

I have two road bikes and my original bike is a hybrid with 700 wheels, the tires are spent because it spent the winter on my trainer. This summer/fall I want to add nice tires I can ride in the snow. my tires now are 700x25 what size cyclocross tires can I put on this, suggestions from Nashbar?

If your bike can handle it, Ritchey ZED Pro 700x42 (http://www.nashbar.com/profile.cfm?category=121&subcategory=1196&brand=&sku=11023&storetype=&estoreid=&pagename=).

I have some studded monsters as well. But as long as we're talking snow not ice, I'd recomend
a pair of agressive patterned wide low pressured tires.

Yeah, I was looking at those, I was not sure if the 700x42 would be too wide for a wheel that currently uses a 700x25. Thanks for your help.
