If you're selling them, ask the buyer pay the extra shipping and let it go. You are going to lose (a) your time and (b) money for tools breaking these down or (c) money to the shop that you'll not get anything of value for. If they were for yourself, you'd realize the benefit of a little expense, but this is money spent for someone else's benefit coming out of your pocket. You are now in the hole. Don't forget you'll have to get rid of the tires somehow too, which if legal, isn't always free. I've been there many times bro, and to keep my word, I came up short in the end.
