I was looking at the Pilot online; it looks like it comes with 25mm tires and it also has fender eyelets, etc. So it might be more "fat tire friendly" than the bikes we used - a Cannondale R800 and some kind of aluminum Trek road bike.

Here are the Nashbar deals:

I like the idea of a $10 32mm Pasela, if you can fit it.

You can see where the tight spot will be by looking at where it's close with your current tires. Small clearances are likely (with modern brakes) between the tread of the tire and the caliper. Also, the chainstays and side of the tire, and maybe the fork and side or tread of tire.

Be warned - 28mm tires don't slip nicely through the calipers - this is less of an issue if you have a flat, because you can squeeze a flat tire through without trouble, AND you can put the wheel back on before fully inflating.

If your wheels are not true and dished right, you will have less tire clearance on the side of the tire. And a broken spoke will be more likely to cause rubbing if you are running wide tires. So carry a spoke wrench and know how to use it. Of course, I may be paranoid about spokes because we had a spoke break.
