Bought a kid's 20" bike today at GW for $8. It's pretty ugly...but the tires are GREAT! Going to cannibalize this bike for the tires and use them to replace the tires on my wood cart.
The replacement tires for these carts are around $60 ea. and shipping would be almost as much as the tires combined. So...did a little digging online to see if anyone successfully substituted bike tires for these carts and they have. So I will too. No, they won't be rated for the wt. bearing that the cart tires are, I'm sure, but I'll take that chance.
So...for $8 for two tires instead of $120 plus shipping, I'm thinking it's a GREAT score.
