RE: Official HPI MT2 Thread
The Moabs are made for 2.2" wheels, which is what the MT2 uses, so yes, they'll physically bolt on. The only problem is they're taller than "standard" 2.2" truck tires, so you might need to do a little trimming on the body behind the front tires to open up the wheel opening so the tire tread doesn't catch when the wheels are turned.
I've been running Masher 2000s on my NMT for years and I think it looks great, a little more meaty than the stock tires. The Moabs are the same height as the Masher 2000s, but the Moabs are a little narrower.
I've got some Moabs I could bolt onto my NMT if you'd like to see how it looks.
