Tyre fitters and tyre depots offer little consistency in training of staff, approach to the job or equipment used. Eventually I learned that you shouldn't bother with the type of tyre depot that specialises in replacing budget tyres on 10-year old Ford Fiestas. If you go to a 'commercial vehicle' tyre fitter you are more likely to experience vastly better levels of expertise and experience. For example, the 'cones' used to centre a wheel on the balancing machine are rather expensive - so if the tyre depot rarely does 4X4 tyres - they won't have the special 'Ford Transit' sized cone that is essential for doing the job effectively. Also if the 17 year old 'tyre fitter' was recruited last week from a local Pizza shop - you are unlikely to experience satisfaction with your wheels and tyres. Top tip - Find a local specialist and don't waste your time and money. I use a truck tyre depot, who also does my tractor tyres and the chap that does the job has been on the tools since Adam was a boy.

1.Find someone that knows what they are doing.
2. Cones don't work on the Gen 4 mags, they must be PCD balanced.
3. Check the roundness of the tyre. I fitted Grabber X3, the rep replaced 4 out of the 5, and one of those needs replacing too.

Tell us more about PCD balancing as opposed to just "Cones don't work on Gen 4 mags". Every day is a school day and I've had several disappointments at tyre depots over the years.

Ask the tyre place(s) to balance hub-centric and not stud-centric as saxj says

The wheel has to be mounted to the machine so that the centre of the wheel is in the same place as it is on the car.
Most "modern" cars have a turned metal ring on the hub, that locates the wheel centrally using the machined centre hole. (This corrodes instantly, and you can't get the wheel off) The nuts are flat or reduced diameter at the bottom, and rattle round in the holes, as they are just to keep the wheel on the hub.
The jimny has tapered wheelnuts, and it is the centralising action of the nuts in the tapered holes that both holds the wheel on, and keeps it central to the hub. (Now the centre of the hub just rattles round in the big central hole of the wheel)
If you balance it dynamically, using the hole, by poking a tapered cone through it, there is no guarantee that the wheel is running true, and when it goes on the hub, the dynamic balance will be miles out.
So the fitter has to root in the box by the balancer to find the mounting flange, and swap it over with the cone and then bolt the wheel on properly, which takes ages, so they don't bother.
A commercial vehicle place always uses the flange as truck wheels don't have a centre hole.
If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

The mags on both the 3rd and 4th gen Jimny's are cast, so the surface is irregular, which protrudes above the machined centre of the wheel. When using a cone it rests on this irregular surface causing the tyre not to balance properly. PCD (pitch circle diameter) balancing is done using the stud holes.

I'm a user of balancing beads but with those tyres, on that car you should not be having these issues. Perhaps balancing beads are your easy solution though.

sorry to hijack this thread momentarily, I may have asked this before (sorry grey cells are not what they were) have you had any issues with the balancing-beads at low speeds?
...or put another way, at what speed do they become effective? Or is it something that you don't really notice?
I'm considering balancing beads in my prewar car( lumps of weights added to wire wheels just looks very ugly)
IF IT AINT BROKE, KEEP FIXING IT UNTIL IT IS
