Just had mine changed. I had moved them rotated after 7000 miles but then somebody decided to hit in the side of me at a roundabout at about 10700. One tyre was damaged, fortunately the rear which was almost shot so got one under insurance and I've since replaced the other and rotated the new back to the front again. Unfortunately it's the same brand which I was hoping to change.
Interestingly, the repair company paid £188+vat, I paid £125+vat from my local dealer :)
Will see what this second set run like
