Wobble / vibration through steering wheel at 50 to 55mph

Just fitted new wheels and tyres ( sawtooth with bfg 265-75-16 AT's) which were balanced by the supplier. I noticed a wobble/ vibration at about 50to 55 mph through the steering wheel. I then took them to a local tyre fitted and had them re balanced and he had to put a few more weights on,his machine gave the front tyres the green light and we were good to go.
The wobble is still there on some road surfaces at the same speed.
As a long shot, will get the rears done as well, has anyone experienced a similar problem and is there anything else I can try to eliminate the issue ?
The Landy has only covered 600 miles, so I don't think it would be bearings or dampers( problem did not exist with factory steels on).

Experiencing EXACTLY the same thing at the moment.

Been running 265/75x16 BFG's on ZU's for years without any problems whatsoever. Fitted 265/75x16 ST Maxx on Sawtooth's and I also have a wobble at 50-55MPH. Tyres are balanced ok and there are no problems at higher or lower speeds but I get the wobble at this speed regardless of the road surface.
I am going to check the swivel pre-loads but it is a brand-new LRGP axle and was fine with the old wheels / tyres fitted. ONE LIFE, GET IT!

Worth checking the suspension bushes, mainly the Panhard arm and Radius arm bushes. Get a good pry bar and check for movement.

are both of the new sets of wheels the 'copies' by any chance?

Mine are.
Another long shot is, I have locking wheel nuts, could these throw the balance out if they are a different weight to the standard nuts?

yes mine are copies.
i run them at 33psi, but i have got rack and rooftent fitted.
no wobble at any speeds ,the mud terrains would go out of balance all the time.
saved them for winter use and lower speeds

Cheers for that, next stage is to balance the rear ones again and swap them over to see if that helps.
