24" ISO 520 wheel outside diameter?

[[email protected]]

Hi All,

I'm working on building up a road bike for my kids. I wonder if anyone
knows the outside diameter of 25x520 tires like the IRC Triathlon? I'm
puzzling through the differences between 520 and 540. I'm trying to
determine which wheel size I should lean towards.
