I have the new MTR's, I also ran the old ones. They are great tires, I would recommend them. In regards to the Toyo's, my bro has had 4 sets of them and loves them. They seem to be a bit harder material, and they weigh a TON. They have very stiff sidewalls, and he runs them at 6-8 PSI on his crawler, 35 PSI on his truck. People that have the Toyo's love them and swear by them. I really like how they perform, but they were too heavy for my taste, and the MTR's were also less expensive.
