To be a little more precise, this review is for a 525i wagon but the vehicle dynamics are much the same as the sedan.
Negative reviews about this or any other all season tire should be taken with a grain of salt if they've been written about their performance in winter conditions. Why tire companies just don't call their so called all season tires THREE season tires instead, is beyond me. All seasons are CLEARLY inferior in winter to purpose built winter tires which have rubber compounds that don't harden in cold weather and treads that better deal with ice and snow conditions. The minute the weather/pavement goes to freezing, your tires' adhesion factor is severely compromised to the point of danger with summer or all season tires. So whenever reviewing an all season tire, I suggest going back to comments written in the summer, spring and fall for a perhaps more balanced outlook. In the meantime, these MXM4's are beyond all expectations for quiet, smooth and safe running in the wet and dry and look like they'll last a long time because at 10,000 kms, they don't appear to have worn AT All! Highly recommended. For better longer lasting wear for ANY tire you choose, I'd strongly suggest a wheel alignement IMMEDIATELY after purchase. I find the Tire Rack tests/comparisons very helpful for gaining a true, balanced and fair professional opinion. Hopefully you'll find a Tire Rack test for a tire you are considering. Sure, they sell tires and you might think that they'd have a vested interest in writing glowing reviews for every tire they sell but if you study their tests, you'll see that that is not the case.
