Not really. The 'c' goes with '700'. A 700c rim has a diameter of 622mm. It's not 15 'c' wide, it's 15mm wide...most likely internal width. OP, if you use the proper terminology you won't have asshats like me correcting you all the time. Your rim will work w/ a pretty big tire, at least 32-35mm no problem. Many of us did this for years on CX bikes. One problem that others have mentioned is getting the tire out from between the brake pads when you remove a wheel. A bigger problem (if you have a road bike w/ caliper brakes) is having enough clearance for the tire in the first place. If you have normal road caliper brakes you're gonna be limited to 28mm tires at most.
