Have put the Coopers on Defender, 7 ply MTs become very heavy, 26.5 kgs to be exact. Defender is used as a recovery/service vehicle during rallies or for slow offroading and touring up north so Coopers are fine on it.
Evo being a speed machine, needs lighter tyres hence Cooper MT, because of their weight, would not suit. Already have All Terrain BF Goodrich 265/75/16 (6 pieces) for Evo, each BFG weights around 22 kg. BfGs have 6 ply base and 3 ply side wall so I am quite satisfied with them. Recently also purchased 4 GT Severo 265/75/16 MTs. These weight around 21 kg, so if Evo requires MT, would put Severos on it
