Thanks for the comments guys.
Those are big tires. I see it related more to the real world big haulers you see at a strip mine than tank transporter. But to each their own.
TRO with 2 lift hoists will let it transport 70 tons.
Mass 50 tons, MP 4/6 ICE, 2 tons armor, crew cab (0.5 tons), and 20 tons cargo.
