touring wheels

I have 700c wheels on my road bike. I've been riding with 23mm tires but one blew out recently so I'll need a replacement.

I've been thinking about getting something wider, more suited for touring. My question is if I need a special wheel set, maybe wider, for touring wheels. Everything I've read about touring wheels suggests a 36+ spoke arrangement, which I have, but I'm curious if my rims which hold 23mm tires oh so well can handle a larger tire. Or do I need a different wheelset for touring?

Whatcha got for a bike? How much room does it have before the tire rubs against
the brake or frame?

You first need to measure how wide a tire will fit between your chainstay forks, as alluded to by "late". If you have a road bike it is not likely that you can accommodate anything wider than 28mm regardless of what wheels - or more precisely - what rims you planned to get for touring.

The late Sheldon Brown has a great chart to show workable rim/tire-width combinations:

You will have to measure the inside of your rim.

Okay, this answers the question that some road rims are wider than others. I wasn't sure about that one.

So, where on the tire does the 23mm measurement get taken from? And if I were to put, say, a 32mm tire on instead, would I really need 9mm more of clearance?
