Never thought I'd get annoyed hearing the engine noise of my Lexus - but with my MXM4's that is exactly what is happening. They are so quiet, that for the first time I began to notice and get annoyed by the noise pattern of the engine.
Secondly love the handling, especially in some snow. The previous OEM tires were as effective as gripping as skates on an icy pond. Did not get a chance to drive through heavy snow yet, but I am not expecting these to outperform nor are they designed to. As long as I can get through normal city snow driving - I am good.
Otherwise handling of the car is much improved. Not that much of a difference up or down for fuel economy. And the tread seems to be holding up quite well.
