I haven't seen any in the places I've been looking that are anything other than "700." Are my tires *that* much smaller than every other 56cm bike on the planet?
Your rims and tires are not 700C but what is commonly known a 650C (ISO 571) and were sometimes used on small frame bikes to keep the rider's toes away from the front wheel on tight turns and on triathlon and time trial bikes as they were a bit more aero. 650C tires are available but not nearly as common as 700C so you will have to look around.
BTW, the most common 26" size these days is the mountain bike ISO 559 and there are several other "26 inch" size rims and tires, none of which are interchangeable with your 650C or each other, so be very careful what you buy.
