Sometimes, people who don't know about sizing will just take a tape measure to it rather than reading the actual numbers off of a tire. That's what those numbers sound like.

Basic math .. Diameter = 2x Radius.

I believe they are giving you the frame size in cm and inches. A 64 cm frame is close to 25".

That's a big bike. I hope that you're over 6' tall.
