I have never heard of the fronts that are on it at the moment, and I do realise that tyres are VERY important as its that little patch of rubber that keeps us on the road.
These are the current front tyres:

They are at the cheaper end of the prices, I will admit to liking the 'look' of the tyre tread, and according to that website the ratings of C & C and a decibel of 73, That is actually not that bad, compared to Mitchelin Diamaris (which everyone seems to mention) they are actually quieter than the Mitchelins.
Lets be clear:
I am not going off road with my BM - so I dont need mud pluggers
I am not a boy racer anymore - so I dont need 'slicks'

I am not 'well off' - so price IS important (but so is safety)
I know 'winter tyres' would be ideal for the coming months, but I cannot afford two sets of tyres, nor could I store them.
Vainly I do care about how the tread looks,

SO (short story long) What are the BMW Officially approved tyres for an 2003 4.6iS?
Current tyres are 275/40/ZR20 106W XL (think the XL is irrelevant)
