Goodyear Wrangler Silent Armor problem

At first the only thing Goodyear said they were willing to do is give me a credit (prorate) for a future purchase. I explained although I appreciate the prorate on a future purchase, I am faced with the expense of 6 new tire now. I got a supervisor on the phone today that is willing to give me $300. Although it's no where near what 6 new tires are costing me, I guess it's better then nothing. The aggravation alone is worth more then this. So much for being loyal to Goodyear, I have 3 vehicles with Goodyear tires not to mention my 5th wheel.
