How wide of a tire can I go?

The Good All-Around Tire thread made me think. I want to prepare my road bike for a tour and I want to add wider tires. How do I kow how wide of I tire I go? I am currently using 25C tires on a Cannodale SR500.

How wide can I go?

How wide should I go for mostly roads?

Most road bikes will take a 28 in the rear and some forks a 25.

Thanks

A SR500? Or just a road bike? Does the model matter?

How wide can I go?

How about taking your bike down to your LBS and trying to fit a few wheels with wide tires to see if they work? Hybrids usually have wider tires. You want be sure that you have brake and fork clearance.

The "new 29-inch tires" that are now available on mountain bikes are actually 700c tires (ERTRO 622 mm). A quick look at tire websites shows that Schwalbe and Continental both make a 54-622 tire. It won't fit on an ordinary touring bike, though...

A good place to look is here: http://sheldonbrown.com/tire_sizing.html The widest tire you can fit will depend on your rim and your frame clearance. Look at your current tires - are they pretty close to the frame? Is there room for a larger tire? Wider tires are likely to be taller as well.

My full-on touring bike can only go to 700x42 according to the builder. 700x38 was the limit with fenders. The guy who said take it to a bike shop was right on the money. I found a German tire company, not Schwalbe, that offered a 700x60 tire. A friend who was an HPV builder laced two MTB rims together with two tires side by side and built a frame to hold them. Used it to ride in sand. He rigged a jack shaft/transfer reduction gear to give him a 3 gear/inch low. One spring I followed him up Fargo Street in LA; a 35% grade. He was pulling a trailer with his infant son in it.
