No, you can't use any 20" tire. You have to ensure that the overall diameter of the new tires is within a couple of percent of the original size. This tire size calculator recommends within 3%, but the closer to OEM diameter the better.
Tire Size Calculator - Tire & Wheel Plus Sizing
Tire Size Calculator - Tire & Wheel Plus Sizing
1) 275/45/20 (sidewall height: 123.75 mm, diameter variance: -1.18%)
2) 265/50/20 (sidewall height: 132.50 mm, diameter variance: 1.11%)
Leaning towards option 2 as that gives me more sidewall and a slightly narrower tire. Tire Rack does list 265/50/20 as a winter tire option implying it will fit?
Anyone have any thoughts one way or another, between these two options? As always, your inputs are greatly appreciated.
Thanks!

NABS4, Thank you that tip, that calculator is great. I want to go down in width compared to the OEM 20" (285/40/20), and I've narrowed my choices down to these two,
1) 275/45/20 (sidewall height: 123.75 mm, diameter variance: -1.18%)
2) 265/50/20 (sidewall height: 132.50 mm, diameter variance: 1.11%)

I would go with 255/50/20 as it is within 0.3% of the stock 285/45 R20. So your actual speed at 60 MPH would be 59.8.
With the 265/50/20 it's a 1% difference so at 60 MPH you will actually be doing 60.6.

You, Sir, are correct. Thanks for pointing that out. I'll see if 255/50/20 is available in the Nokian Hakka R2s. Placing order in the next couple of days.

Turns out the 255/50/20 Nokians are out of stock nation-wide. Demand was higher than expected and Nokian sold out, new stock is expected to arrive around the first of the new year (according to tiresbyweb).
265/50/20 is available, and I know it will fit but just not as close to stock as the 255.
What would you do in my place, wait for the 255 or get the 265? I live in MA, there's probably a 50/50 chance of meaningful snow by early Jan.

Thanks for sharing your thoughts, Lookout.

Yes, I want to stay with Nokian. With the 265/50/20, I get a little more sidewall (+ve?), but a little more width (-ve?) as well. And the greater speed variance, does that hurt the car in any way/cause more wear, or is it just an annoying measurement error?
Thanks for sharing your thoughts, Lookout.

I just bought Continental DWS06 275/45 20 $225 each
20X9.5 AVARUS AV15 TITANIUM 32 offset. $99 each
From Tirerack. $1580 total Just to use in winter months. Summer 21" came on the Q7. Not real blown away buy the look but will get the job done and great price
