THE SLEITER "ELEPHANT" ST 816 needs and would benefit from expanded tires like the offroad ,all terrain, chained and highway along with the JAT dlc pack too. it was originally a 6-speed transmission, not 4, as I just found an old PDF archive of an old pamphlet and translated and read it and also has a range of 600-700 horsepower and could move 250 to 315 tonnes and also originally intended to be used off-road as a versatile model of a semi-tractor unit.
