I am trying to replace the original tires and wheels on my Schwinn Super le tour 12.2 (there really old). I am confused by the sizes (700cc and 650cc). I measured the wheels and there somewhere around 24in without the tire. I read somewhere that 700cc is close to 29in wheels. The guy I bought the bike from advertised it as a 24in bike, but I didn't think bike sizes went off of wheel sizes. If anyone could help me out that would be great. Thanks alot!

The tires on my bike read 27X1/8
