Workshop/Diary - Tyres

On having the Beamer checked out at my local Dealership 'Sytner' and spending £50 for a diagnostic concerning the battery drain, they decided to inform me of everything but the cause of the battery drain, this included the wear of my tyres: It was more like an MOT, but without the MOT certificate....

Tyres:
- n/s/f tyre put on in the wrong direction
- o/s/r tyre worn down to 2mm and 0mm on outer edge - advise replacement

I did have to shop around and found my local Plume garage promoting this make of tyre and decided to do some research:
