New Maxxis tires are 2 years old???

This seems to be turning out real well. Both companies handled this excellent--couldn't have handled things better at this point. I called Summit Racing (place of purchase) and they gave me 3 options: return them for full refund, send them back and they would try again hopefully for a newer set, or credit me $100 for the fact that they are 2 years old. They were willing to pay shipping for whatever I decided to do. So I called Maxxis and they were also unbelievably helpful. The person explained getting their product from Thailand to USA is a challenge, big ships sit at ports for a long time (but not necessarily 2 years I assume?), and other factors. I didn't ask for the name of the person I was speaking with, but she said she would not hesitate to use them--even after I expressed my concern about ST tires (which this post wasn't intended to be a LT vs. ST debate), she said, "blowout with our Maxxis M8008,that is not normal." Maxxis changed their warranty because of the time delay from 3 to 5 years.
But to help all she could, she offered to contact Summit and their distributor (nobody buys directly from Maxxis, everyone has a distributor), and a distributor near me to coordinate getting mine returned and a set of 4 with at least a newer date to me. I questioned more about the heart of the problem, "Are these tires fit for use knowing they have been sitting around for 2 years or not?" She assured me, AS LONG as they were in a controlled environment, they should be ok. Well that's a lot of shipping expense/coordination by everyone involved, so I said if you (Maxxis) believe they are ok, then I will use them. I called Summit back, they said they would issue a $100 credit because of the age. As I type this I feel a little guilty about that, honestly, but I did not expect my new, dependable tires to start off 2 years old so I'll take the credit, put them on and hope for the best. And in the future I will explain to anyone looking at buying new tires, purchasing from Summit Racing worked out extremely well for me, very happy with how they handled my concern, and also Maxxis is a very good company to deal with. I was able to speak with the appropriate person (someone from the "tire research department" of trailer tires) and got exactly the information I needed and pleasant to speak with. Now I hope she was right, time will tell how these work out but I have a good feeling. I plan on updating this someday to explain how things go over time, we will see. Thanks for the replies.

Just because the folks on the phone that represented two companies were nice to you changes nothing about the old(er) tires you were sold. We all make different choices and mine would have been to send them back and get some with a better date code. What is $100 over five years of tire life? As far as ships in port, their costs don't stop when in port so the ship gets loaded as fast as possible and back out to sea, and then again unloaded as fast as possible to turn around and get to sea again to make money. That comment was all about smoke and mirrors on their part. What the warehouse did was make sure the older tires were sent out first and you were the recipient of that hoping perhaps that you would not notice or care. Summit apparently did not check date codes either before selling them to you. And you think Summit handled this excellent for you?
