I have now had these tires fitting for about 1.5 years. They are in a 35x12.50R17 size, load range D.
Overall, these are perhaps the best AT tires I have ever had. MT has done an amazing job getting these tires to have a smooth, quiet ride on the street, while also providing fantastic traction offroad. I have had them on dirt, rocks, and plenty of snow.
The tires are a bit on the heavier side due to having a more robust, 3 ply sidewall with sizable side biters. When aired down these really do help protect the sidewalls while also giving additional traction.
On the street, their noise level about average for an AT, despite them being more aggressive than most AT tires. This can be attributed to their asymmetric tread design. My Jeep has more wind noise than tire noise. They have full depth sipes which aid in wet traction, and aid them a lot in the snow. While they will not perform as well as a dedicated snow tire, they are 3-peak rated and have gone everywhere in the snow that I have asked them too. They have also had great tread wear. I live in the mountains, and our roads are known for chewing up tires faster than average. These have done well.
Offroad, these tires really shine. They have larger, deeper voids than most ATs. These really are more of a hybrid tire with an AT name. They will not due as well in deep mud as a dedicated mud tire, but they easily out perform AT's like the BFG KO2/KO3 in the mud. Their compound seems to work pretty well in the rocks. They are not as soft as some more purpose built rock tires, but they do well enough for most.
Its worth noting there is three versions of this tire. The P rated tires have much shallower tread, and the side biters are more of just a shallow design element and do not provide much protection/traction. There is the LT rated tires (eg: 35x12.50R17), which are designed for Jeeps/Broncos/etc and have a load range C or D depending on size. These have a softer compound, deeper tread, and deep side biters. Then there is the metric sized LT tires (eg: 315/70R17) which are load range E, and use a harder compound. These are intended for diesel pickups and such. Do not put these on a Jeep, you will hate them.
