Greetings just picked up my new Audi Avant and am planning next summer. I am going to take the 17" wheels that came stock and make those winters...so my question is with stock suspension should I go as big as 19" wheels or just move to 18"?

Anything other than optics I should be aware of?

 

I have a '12 s line A4 with 19's and no issues don't see why you would have any with stock suspension.

 

No issue if you go with 19
It all comes down to what is important to you...
Yes 19 looks amazing, improved handling...etc.
on the other hand, 18 will cost less, and especially more comfortable in daily driving and or commuting -

 

imo unless you want to drop the car a litlle bit 19's wont look as good with wheel gap...

 

17", 18" & 19" wheel/tire combination all have the same circumferences so why would the wheel gap be any different?

I run 19's both summer & winter:
