I just picked up a set of 20" XD Battalions with 33 12.50 Federal Couragia tires. Normally I would have never bought M/T tires but the deal was too good to pass up, $1200 and they even had TPS sensors. The tires are pretty loud on the road and I'd like to try to quiet it down as much as possible. I'm thinking about picking up some dynomat and giving that a shot. Any other ideas besides that or getting new tires?

That is definitely an aggressive looking tread pattern. Your best bet would be to find someone that wants to trade an A/T for a M/T or sell those and purchase new ones.
Otherwise your tearing your entire interior apart to apply some additional sound deadening.
A rubberized undercoating may help a bit though.

I'm slowly getting used to the noise. I took the inner front wheel wells out and covered them with 80 mil fatmat on the back sides. It help a little bit, Ill eventually get around to doing the doors and see how it sounds inside. I'll probably do the rear wheel wells tomorrow. I took a ride in my buddies truck that has mud grapplers on it the other day and those things were 10x louder so I guess these aren't so loud after all.

Dynamat type products do help but just so much and is only 1 step of true sound deadening. Look into mass loaded vinyl and so forth. The link I posted above tells all.
That is a ton of dynamat. Right now I plan on doing the rear wheel wells, rear cargo area floor, front floor boards and all 4 doors. I had my seats folded down from when I picked up the wheels and tires and just flipping them back up made a surprising amount of difference in the amount of road noise.

That is a waste of dynamat. You only need a little of it. As Coatwolf said if you want to block AIRBORN noise you need mass. Any type of mass will do. MLV happens to be the heaviest for the least money. The expanding foam is also a rather bad absorber. If you are going to stuff the pillars and such buy some 3M Thinsulate acoustic insulation as it is by far the best absorber in that application.
The dynamat is to dampen structure based noise. While the tires will transfer some energy into the panels creating some, it will be dominated by air born.
Don from SDS Showdown above is exactly who you should ask for help. Expect a slow response, but unlike other vendors he will sell you what he needs and not some arbitrary crap that doesn't do much.
The difference is HUGE btw. GM really cheaps out on the NVH package. So much better once addressed.
