Default Max Rolling Diamter Difference From Stock

I'm planning on getting some wheels. Specifically some Vossen wheels.
Current looking at 20x9 for front and 20x10.5 for rear. The tires are 245/35/20 and 285/30/20 Continental DWS. The diameter of the 4 new tires are about the same. However, it is 3.3% different from stock. Is this gonna caused any problem with the AWD system?
I'm ready to order now. Just making sure that it's not a problem.

Yes those tire sizes are fine for AWD but I wouldnt suggest them...

You should be 295/25-20 (r) & 245/30-20 (f)

Thanks for your input and suggestions. Your recommendation does matched the stock quite well.
However, the continental does not offer 295/25/20 in the DWS. I can, however, get the DW. Any difference between the two tires?

DWS = All Season
DW = High Performance

If you get snow and plan to drive this car with these tires DWS...If not DW is the way to go.

Okay, that's what I'm afraid of. But I thought as long as the 4 tires overall diameter is the same, it should be fine.
I'll just get the DW tires with 245/30/20 and 295/25/20. I'll have snow tires or use the stock runflats.
My stock wheels are 225/50/17 btw.

Yea I would toss the OEM rims and tires back on for winter or even swap out the tires for a snow or all season tire. This way you wont chew up your aftermarket rims.

Alright. I wasn't quite comfortable going with such low profile tires on the 20s. Especially when I have to do a 600miles round trip to Montreal. Montreal streets are not that friendly.
I went with 19" wheels instead and tires size are 245/35/19 and 285/30/19.

Nick, will you have any problems with rubbing? Did you do any modifications for those 19's to fit?

The wheels are just ordered. Won't be in until at least next week. It's funny because after I ordered it, the forecast is 6-10" of snow for today and tomorrow. So I think winter is still sticking around. The wheels won't go on until probably mid March earliest. I will also have BCR coilovers install at the same time.
