Marathons have been made in China in the past although there is rumor some sizes are once again made in the USA. The China Goodyears have the same rep as other Chinese tires...BAD. I have not heard any bad about Maxiis. I will be buying new tires next spring and will buy Maxiis unless something else happens along.
I have a set of Carlisle tires on my trailer at this time and so far I have been happy with them. I was told at the time of purchase that they were made in the U.S. I have not attempted to verify this.
