I was considering both when I was looking at tires, I bought them online though some website, paid a little under 900 for all 4. Then I sold my duratracs on fb marketplace for 400, I only had 8k on them. The weight difference between the stt and mxt was why I went with the mxt, the stt has that triple side wall reinforcement. I don’t rock crawl so I didn’t need that, and that also adds to the weight of the tire. I drive very hard and have about 8k on the mxt, I can barley tell I’ve driven them. I think they are pretty quite. I’m excited to see how they do this winter.
