I replaced the original Michelin 4x4 Diamaris after 45,000 miles with Continental ExtremeContact DWS two weeks ago. I have a 2006 BMW X5 4.8is with staggered wheels, Front 275/40-R20; Rear 315/35-R20. I have driven about 200 miles on the new tires so far. The cabin noise has been reduced drastically. The BMW Bluetooth system is now usable pass 40mph. I used to get so much cabin noise that the other party couldn’t hear me if I was on the car Bluetooth.

I feel the side walls on DWS are a tad softer than the Diamaris and the steering doesn’t feel as sharp as before. The steering is still very responsive just not as responsive as before. To test the tires and handling, I took an off ramp at about 70mph and I felt the tires side walls are not holding up as well as the Diamaris. I did the same off ramp around 80mph with the Diamaris and no problem. At the end of the day, it is a 5,000+lbs SUV. So, I am ok losing some steering response and gain more comfort and quiet.

So far, the next set of tires will be Continental ExtremeContact DWS again.
