They have the same mold as the Toyo MT.
Fuel MT, Durun Terrainmaster MT, and AMP MT share the same also.
I sell the AMPs and are cheaper then those.
But, they are not in the same park when it comes to ride quality as Toyo.
But, I am a firm believer the Toyo is a way better ride and will last longer.
I am sure these Tuff Tires are another one off the knock-off tires of Toyo
