I was never a fan of the OE 19"
Msport wheels on my car and I miss the look of the 21" 311's I had on my 7 series. I just bought a set of 20" 311 and got the shop to replace the Dunlop RFT tires will Falken FK453 tires.
So far the tires are amazing! Much smooth and quieter then the 19" Goodyear crap run flats and even smoother then the Conti DWS.
Very happy with my decision!
