Nice thread.

BTW, I have not tried them yet, but have the Conti Snow tires from last season that I used on my 2001 S8 on the stock "wagon cart" wheels, they were AWESOME on snow and ice, but have a much less "aggressive" looking tread design. I've had some excellent results from both the Conti and Blizzak snow tires on my Audi's, they are pretty much unstoppable if you don't try and push through 4' high snow banks, and get high centered.
I have 255/35-20 Bridgestone Blizzaks on my S6 in the winter (on VMR 20x9 wheels). They look great on that car, but the pothole minefield we have in Pennsylvania makes it a brutal combination. That's part of the reason I went with more sidewall/less wheel on my KO2 setup for the Q5 (plus the fact that they don't make any 19" KO2s!)

I get fantastic snow performance from my Blizzaks in the S6 and suspect that the KO2s will be better than all seasons, but not as good as dedicated winter tires in wintry conditions. I had at one point considered leaving the summer tires on my S6 for the winter and trying out the winter tires/wheels from it on the Q5 (I don't know whether the bolt pattern is even the same, but I figured it's a pretty cheap experiment costing me nothing more than time in my garage to find out) but ended up putting the winters on the S6 anyway because it was scheduled to snow the day of a scheduled service appointment for the S6.

The K02's look great! I might have to get a set. The stock "all season" tires are not the best for Canadian winters or off road for that reason.

So cool that I [maybe] started a trend. Looking good, folks!

Any feed back on running a 255/55/18? I am trying to expand my options over just 235/60/18. and the 255-55-18 or a 245-60-18 seem like viable options

Warhead I'm onto my 4th year with 235/60-18 Yokohama Iceguard iG51s.By the end of another Quebec winter they'll have 50k kms.They have been absolutely excellent in all respects.Going with 255s will just make your vehicle more "floaty" - technical term LOL.If money is no object I'd seek out Hakkapeliittas - the best but at very least try to keep them skinny as possible.

Its not a matter of money being no object. it's quite the opposite. I am hoping to find a set of used ones if need be. I just don't have the coin to drop 700+ on just tires.

I installed my 255/55-18 KO2s two weeks ago and immediately took the Q5 on a 200-mile highway trip on dry roads. Definitely more road noise, but I didn't have any problem with ride quality. Then my wife used the Q5 for a week while we loaned her minivan to family visiting from out of town.She said that she had a couple of strangers compliment her on the tires unsolicited, which is pretty sweet. Nobody has said anything to me thus far about the tires.

Yesterday I began driving the Q5 regularly on my 120+ mile roundtrip to work. I noticed that lateral wet traction is way worse than the stock Goodyears. For example, I don't ever recall seeing the traction control light in my first 20,000 miles with the Q5, but lit it up accidentally yesterday in rain. On the highway it tracks stable, and I just need to remember that it's not a sports car and slow down on curves, especially when wet.

Default How is the KO2 setup?

How has the setup been on your Q5? Any winter Sri I gotta yet? Gas mileage?
Thanks

I have had no issues; driving on wet, forest road, or freeway. Snow has been fine too. For sure more road noise, but not bad. My last ride was a Rubicon that was much louder. Mileage has typically 25-27mpg. 30mpg on long freeway trips. They can be squirrely if over pressurized. I run at 40psi. Don't expect them to handle like 20's. They are truck tires.
