Finally have a Maxxis issue!

I had a bought a Lifetime warranty one time on a pair of trailer tires I bought from amaricas tire one time, and I kept the receipt in my truck when needed, so anyway I head to las vegas and a few miles in, one of those tires lost all the tread but I was still able to drive on the treadles tires back to a Americas tires store near the blowout...So I show the salesman my receipt, and he shows me the fine print on the back that says "Trailer tires 3 year Maximimum" so I flip the receipt back over and show him where I bought the Lifetime warranty in writing for this specific tire, then hes like, we cant honor that anyway because its a different store...I was over arguning and I said fine, ill buy two new tires as I figured the other one was ready to blow too, he said only have one in stock, So in the back the installer finds an extra tire that was not in the system, he was like do you want it? I said nope..So after he was done installing my one tire and he walked away, I walked in threw the new unmounted tire in the back of my truck and was on my way! F Americas tire!
