They road tested.....and I did as well putting it thru forward and backward hard turns and up/down a VERY steep driveway...basically worst case scenarios......I found no issues. However, my caveat is that this is a MY2015 Q7 & it does not have the adjustable air ride feature. Thus, not sure for those other folks considering doing this that may have different MY/etc....but wanted to post this result.

Also, I had friend who is part of large national tire wholesaler and he said/confirmed that the Conti new ExtremeContact DWS06 tires are really great product. I have not had extensive driving yet but as "new" tires both on aux streets and highway (I did test at up to 70mph) they road great. I will say the Pirelli P-Zero is perhaps slightly better ride but with them wearing out at ~15K miles, versus the DWS06 having 50K mile tread warranty, it was no brainer choice. Maybe other folks can afford $1300+ a year for tires but not me. Anyway, for those considering on size concerns and ride the DWS06s seem great ride and DO fit Q7.
