I know it's a long shot that anyone here can use these, but thought I would give it a try. I bought these tires for a bike that had a 24" front wheel, but they were the wrong size. These are Cheng Shin nylon tires and the size is 25-540, sometimes called 600A. They fit older Terry bikes and also some juvenile road bikes. I think I paid $10 or $12 each for them - asking $10 plus shipping for both.
