Sorry sorry. I was inspecting the wear to see if it could tell me what the vibration could be caused by. It's the right front, straight axle 4x4. It did this last month. So I put a spare on and then had the tires replaced as they were due anyway. It went away for about 1500 miles now it's back. Tire shop didn't find anything worn during their inspection at the time. And the previous tire was out of balance but it wasn't cupped and I've since checked the suspension stuff myself. This is even a new rim as the last one was bent
