Wobble . Shimmy in Steering Wheel at 40-50MPH?

I can feel side to side pulling in the steering wheel between 40 and 50 MPH. it started after I put on a set of 265/75R16 TrXus MTs mounted on 16x8 Rockcrawler rims. I am running a 2" BB with OME shocks on a 2003 Rubicon.

Any idea what this is? Could it be a balance issue?

Thanks

Edit: just had all 4 tires balanced and they are about as close to perfect as you can get. The wobble is still there. It's started since I put the TrXus tires on. It was perfectly fine with a set of 245/75R16 BFG ATs. I guess I'll have to crawl under there again and double check that everything is torqued to spec.

The alignment was done when I put the BB on in the fall, and it tracked fine until I put these tires on. Could it be something to do with the tires, even though they balance fine?

Any other suggestions?

Balance or allignment. Im sure someone else will chime in soon with the the web site that has a good write up on doing your allignment yourself, im not sure what it is.

I had an alignment done in th fall, and it was driving straight before I put the new tires on. I'm leaning towards getting the tires balanced again, just wanted to see if someeone thought it might be something else.

Balance the tires again and it should go away. I have that same thing show up every now and then and balancing always fixes it.

Great tires, but have heard they are hard to balance.

According to the balancing machine they are balanced almost perfect (I watched them do it). One tire needed 4.5 oz, the rest were under 3 oz.
