Thanks Corey.

I agree "flat spotted" isn't the right language but that's what the Jax Tyre fitters describded it as.

Rather than get a new one I'm going to investigate getting it repaired as the wobble it produces is slight and only discerable from 70-80, and even then on a very smoth road. Will report back how it went as others may come across this too at some stage.

Thanks again.
