I am after 4 new tyres and when searching it seems most either have 'BMW Fitment', 'Audi Fitment' or 'Merc Fitment'. Does this just mean they are for those cars specifically or that it's just an OEM fitment?
Generally just means it is logoed with e.g. Audi ring badge in addition to the tyre manufacturers logo.
However, sometimes specific OEM fitments can have slightly different compounds (or at least be advertised as such) to the non-OEM fitment, as evidenced by different "tyre ratings" e.g. the Wet / Noise / Fuel efficiency ratings
