Tire ISO ?

[Crazy Nick]

Sunlite Revolutions Tire 24 x 2.5

I asked the seller if this tire would fit an S-2 and he says that it has an ISO of 502. I'm not sure what that means because I googled 502 mm and it's showing me a 27.5 rim. Has anybody else used this tire and know what rim size it will fit ?

A 24" tire your size would most probably be the 24" BMX size, 507. The 540 is 24 x 1 3/8ths, I have a set of those skinny tires. The size shown on the old tire is the best way to know what rim you have.

It could be he misread it and it's a 507.

I think you're right, supposed to be 507 which would be a 24 inch BMX style rim.
Since I'm using a fender that tire radius probably won't work, but it looks like a nice tire for a fender-less build..
