I'm wearing out my rear right tire in under 8000miles. I took it in for an alignment and was told that they couldn't align it back into shape. A friend told me it could be from worn bushings and to get the toe eliminators. I did, but that didn't seem to help a lot. I had a mechanic look at it, and he couldn't see anything that was bent. Anyone have any suggestions?

Thanks,
Matt
