36x17 Iroks on 17" MRW Steel Locks.

I am running 8 oz per wheel of airsoft. They are nowhere near balanced. Bad shakes from 45-70(won't go any faster:)). I'm to the point I'm gonna break them down and get them balanced with weights.

Suggestions before I go through all the trouble?

Also, I have rotated them front to back with no difference.

I have 35x12.5x15 trxus radial M/Ts, and I used 10 oz of airsoft per tire, and they are almost perfectly balanced. I would try at least 3-4 more oz per tire first.
 
Well I added another 4 oz to the 9 oz that I had. Only in the fronts to start with to see if there was any difference.

There was, Its better, sort of. Sometimes at 50, I get the old shake, sometimes, its not to bad.

Obviously, I have to do the rears too. But its a start.

Think I should add more to the fronts as well?

Have you tried running nothing in them? I am running 42's on beadlocks with nothing inside, no reall issues. I was running 39.5 with beadlocks before these. Had 4 golf balls( they were in the tires and wells when I bought them, so I left them when I welded on the beadlocks) in each of them and they drove as normal as well.
 
If you check my thread you will see I have the same problem. I started with no weights and it shook like crazy. I put 8oz in every tire and I couldnt tell a difference. I then put 4 more ounces the front tires and noticed that it helped some. Then I added 3 more ounces to the front and 5 to the rear. Im running a total of 15oz in the front tires and 13oz in the rear tires. Its much better than it was but I still notice a little shaking at exactly 45mph. Im scared to put anymore beads in the tires, though. It rides about 70% better than it did with no beads.
 
The problem that I see with 'balancing' with weights, BBs, airsofts etc is that nobody, and I mean nobody is accounting for out of round tires. No amount of weights will take care of this. Ive fought this for years and with all types of methods. An out of round tire will ALWAYS feel shaky. Can you have somebody watch you go down the road and watch them to see if this is the case? This will probably be the case.

What do you mean by out of round?
 
Chuckman is on the right track, I have been turning wrenches, and doing tires for years and i've gotten just about every set dead on and i'm very particular. That being said if a tire is molded wrong or has a weak belt etc. in it there is no fixing it. 15oz is a little extreme to get them to balance but it's worth a try, if a tire is off by more than a pound at that size it may be time to retire them. The problem you run into going that high is weight is you lose surface area inside the tire for the pellets to "fall" into.

HTH.
 
I can watch them myself, they do shake side to side. Are you saying top to bottom out of round? I doubt all 4 of them would be that way.

I did add 4 oz to the backs as well and that make it worse. So I'm back to square 1.

At this point, I'm gonna empty them and take them to a tire shop. I'm gonna have them stick on weight balance them and keep notes of the weight amount, if I throw those weights, I'll stick that amount of weight back in it with bb's
