Death wobble at 70km/h

[mudski]

I can see your logic. I also thought the aftermarket steelies I run may have something to do with it, but it dont explain my issue. I have 33" BFG Muds on King rims. I have had the rims checked out and found no issues. A while ago, my tyre shop identified a slightly "out of round tyre" which we thought was causing the wobble issue, but after swapping to the spare, it went away for a while but eventually came back.
I think my issue is tyres. Maybe just one or two of them. As I have a second vehicle as a daily drive, the Patrol is not used as much as before, and as I said earlier, if the Patrol is not driven for a week or so the problem seems to go away until the tyres are "warmed up". Maybe I have one or two "soft" compound tyres causing the wobbles when hot. It gets all too hard and I get a headache thinking about it.

Yeah I think this issue has varied causes from vehicle to vehicle.
