I've just picked up a little bike with square tyres, and am looking for anything to fit it, perhaps someones F3 cast-offs.
I'm happy to trade for big bike tyres, which I have a stack of.

The sizes I need are 110/70R17, and 140/60R17, I'd be happy to try a 150 rear out.

The sizes I have at home are 120/70R17, and 180/55R17
