285-45-r21 is not the oem size for the 21". Its 285-40-r21". There is no still no exact OEM size option in an all season available (at least in the US). One would think something surely coming eventually though.

I am looking at MICHELIN PILOT SPORT ALL SEASON 4 Ultra High Performance All-Season - Size: 285/40ZR21 109Y XL. Has anyone had them? I have always had Michelin’s on all my Sedans so far and love them but have no experience with them on a SUV. So wanted to know if folks have any opinions.

I have the winter setup 275/45/21s Atturro Aw730, excellent winter tire. Car looks/feels good. 45 is good cush for winter, especially. For summers has 22"s, but on 40s.

Just got these a month ago and they seem fine to me. No real differences than the Pirellis I had on before, but almost twice the tread length, so it was a no-brainer for me. My Pirellis needed to be changed out before 20K miles.

From my review on tirerack.com, it looks like the Continental ExtremeContact DWS-06 Plus is the top-rated tire in the Ultra High Performance All-Season category, and is marginally higher in every subcategory (wet traction, dry traction, etc.) than the Michelin Pilot Sport All Season 4, as well as is cheaper to boot. However, the Michelin is available in my OEM tire size of 285/40ZR21 while it looks like the closest size for the Conti for my Q7's Audi Sport 21" rims would be 295/40ZR21. Does anyone know if the 295 Conti's would fit ok on my rims?.

Here is a tire calculator to tell you the dimensional differences. based on this, it doesn’t look like an issue.

Thanks for the info. In my experience, 21" rims are not a really common size, so it's good to know there are a couple of top-rated tires out there for my Q.

In June, I bought the DWS-06 Plus from Discount Tire, where I got an incredibly good deal. Went to the 275-45-R20 from the 285. I've driven almost 5K miles already and they ride really nicely. Couldn't wait to get rid of the RF's. It holds the road in both dry and wet conditions and they even work in snow, although I do have a set of snow tires. You will not be disappointed with this tire.

I had the Conti DWS on my last X6 and they were great , even in steep deep snow ! When I need to get new rubber on my SQ8 that's what I'll be looking at.........

There is a new version of this tire out. There is also a new version of the Michelin PS A/S (4) out that is competing with the new Conti DWS 06 Plus
