Whats the secret

Another "secret" - barter. I clipped a curb in the city about a month ago. Sidewall was split, so no patching it. I know a car mechanic that buys used tires etc. from me. My plan now is to find another used tire or some other thing to trade with the mechanic for another tire. So I took the flat tire off and replaced it with a snow tire, for the time being. So eventually I found a worthy tire, and a power wheels, (for his granddaughter). The steering was busted on the power wheels but he's a mechanic so it's fixable. I took these two items to him, got a new mounted, balanced tire. Didn't cost me a dime.
