    What causes tire wear like this?

    I have a nasty shake at highway speeds. Noticeable at 65, threatening to shake the car apart at 85. Nothing seems loose if I jack up the car and try to wiggle the wheel back and forth. Front right has a bend in the rim, but both tires are worn like this. The tire on the bent rim is worn more than the other side. I know a bent rim can cause a vibration, and I'll be fixing that, and the tires being worn like this I'm sure is contributing also, but how did they get this way to begin with? Sort of a butterfly effect from the bent rim, or something loose in the steering that isn't obvious from wiggling the wheel? Bad alignment? I don't think I've seen a tire worn this way before.

    If it is not a mechanical fault with the car, which seems unlikely, then it is probably a belt or tread separation in the carcass of the tire. They can be very hard to spot and present in very strange ways.

      In both front tires though? Or is the problem in the one tire and resultant shaking causing the other tire to wear the same way?

          My Discovery has scalloping on the rear tires from a sloppy balljoint and worn bushing - any play in your front suspension?

            Shouldn't be, although I haven't gone over it thoroughly, just a basic check. Although it was 10+ years ago now, I replaced almost everything in the front suspension, including control arms, bushings, Z3 rack, tie rods, springs and shocks. Only thing left that I can think of is wheel bearings, and I thought one of them was bad since I have a noise that sounds like it's coming from that corner, but didn't feel any play when I checked it. I'll probably take a closer look at it. I don't put a ton of miles on the car so I would think the parts I replaced should still be in good shape with 40k miles on them at the most.

            From the link ehrawn posted, I suspect my bent wheel is causing a vibration, and that's the source, but not sure.
