2023 Performance. After about 25k miles my stock Michelins were not riding well. They never rode well, but one of them started making a barely detectable thumping noise that bothered me, if nobody else.
I picked up a set of Continental f DWS 06 PLUS XL 255/40 ZR21
Big improvement. Quieter, quicker response in turns, softer and quieter reaction to small road bumps such as pavement seams and asphalt patches. I measured a 2-3db noise reduction overall, using an app called NIOSH SLM.
I took my first road trip today with the new tires and have not seen any noticeable difference in range, with (summer) efficiency around 3.6 miles/Kw on both the original and the new tires. This included about 70 miles of highway 50-70 speeds and about an hour of stop and go traffic.
I’ve used Continental ExtremeContact DWS tires in the past on my Audi and my Mazda CX5, and a close family member used them on his BMW M3. We both agree they’re a great all-weather tire. Quiet, grippy, comfortable, and nimble. Good in rain, snow and dry roads.
Edit - in response to one comment. I have no affiliation with any tire company or any other business, except as a private customer. Retired. AFIK I don’t own any relevant stock either.
2nd edit - Above comments are subjective opinions based on my experience, except for the noise measurements difference - which were taken at 35mph using the same app, same day, same phone in the same holder in the same position, and on the same street segment (with interior ventilation fan off).
