Summary: Excellent mid range tyres. Very impressed with the quietness grip is good. The side walls are so much stronger than the Michelin ps2 and ps3. Only thing I am not keen on is the lack of depth of the tread on the outside edges as bmw 5 series wear on the outside edges anyway.
Summary: I had these tyres for about a year recommended by Tony @ Pumaspeed. They are a great dry tyre loads of feel through the corners not bad in the wet but did feel a bit slippy in the very cold weather we've just had.
