Hmm when I first saw your post I assumed you just got wheels and not tires. Thats really strange since you got tires mounted and balanced too...that means both the person that pulled your order and the Tire Technician didn't see that they were the wrong color. Very rare that they would both miss this.
I can get you set up to have the correct rims sent to you right away. I am going to send you more information via PM to keep your personal information private.
