It should be on the tyre sidewall....failing this, take a wheel to your LBS.

Thanks, I know it should be but they are very worn, and I just wondered if there was a way to measure it.

How about 650? maybe 27". Quit guessing.

Look on the rims.If they aren't marked,take a rim to LBS.

Take a pill mate....how many 650c road bikes have you seen??

Its a Schwinn Worldsport, i guess my question is: Is it possible for me to measure the wheel myself?

that's 27". You can measure the diameter with a normal tape measure.

So if the tires on my other bike are 700 x 20 - 28c, what are these? What do the numbers mean? If i know the diameter, which number is it?

those tyres won't fit this bike. 700c is the wheel diameter, 20-28 is the tyre profile.
700c and 27 inch wheels are diffenret sizes.
