I've openly been a Toyo MT fanboi for years having tried or done recon on many other MT and AT tires prior on the truck. The Toyo MTs last forever, toughest MT i've found, and decent on road noise. They do weigh a solid 10lbs more than your typical C or D load 8ply like the KO2, Duratrac, etc. Given they are a 10ply E load with 3 ply sidewall, that's where the added weight is.
That all said, with the new 17's weight savings, I wanted to keep that theme going and try something new. Best solution I found was the 35x12.5 Mastercraft, which on paper is also a 10ply E load with 3 ply sidewall like the toyo, but supposedly weighing under 70lbs... Have worked well for me for 8k miles, no issues in harsh terrain out west, but the 10lbs of extra material will be a tradeoff somewhere in terms of durability compared to the toyo. These also lack the bead saver that the toyos offer (beefed up material right at the bead of the tire). The mastercarafts do seem to wear quite a bit faster than the toyo too, and possibly feel more road vibration in the pedal.
If comparing the Toyo MT to a Nitto, its comparable model is the Trail Grappler. A few lbs lighter than the toyo, but no sipes. So id say the Toyo is a superior tire of the two for snow/ice folks atleast. Both made by Toyo tho
