Default Deathwobble after new tires

So I put my 31x10.5x15 BFG's on today and I also balanced them. Everything checked out just fine as far as the balancing went. I mounted everything up and torqued my lugs to spec *in hope that there was no room for error of course*. I took off from auto shop to go home and all of a sudden after hitting about 50mph, I started to get death wobble. If I went under 50, I would lose the DW, if I went over 50, I'd lose it the DW too. I got home and tightened everything thinking maybe my trac bar was the culprit when it actually wasnt at all! I think it's my passenger side outer tie rod but I'm not too sure. I still can't figure out why this would all of a sudden happen right after just a new pair of tires. It was never like this before!

If you have an idea of what is going on, or you would like to make a comment feel free to do so I need all the help I can get!

this might sound dumb but when you tightened them down did you hand tighten the lugs first or just run them down with an impact reason i ask is the rim might not be sitting on the studs exactly flush and could cause the above mentioned issue

I finger tightened them, then I used the Impact wrench, and then I let it off the lift and checked all the lug torque with a torque wrench. I'm going to use a breaker bar or something instead of an impact wrench just to see if that was my problem. This might save me the $75 for buying a new tie rod end lol... Thank you!

Yeah I was running 215x75x15 BFG Long Trail T/A's, the part that sucks is I took them off and they only have a thousand miles on them if that. I wish the money spent on those went into my used 31's hahaha

Doesn't sound like deathwobble. It sounds like a missbalance, rebalance the tires again

They're not new. The ones I just took off were new. The set of 31's I'm running at the moment are used takeoffs.

No can do, those rears are a lot less grippy than my fronts and I want steering traction lol. I'm only riding on those particular set of rears till the end of the month when i get paid.
