Coker Firestone 6.40x15 Bias ply tires

These are brand new tires. They are Firestone blackwalls 6.40x15's, tubeless. Never been driven on, just mounted for a bit and taken off the rims. I paid almost $800.00 for them but I need to get some money back out of them, or if you have tire connections, I would trade them for a new set of tires:two 195/50/15's, and two 195/60/15's. Let me know. Thanks Rick 636 978 1996
