2020 A4 Allroad wheels/tires going to 19" (TIRES WHICH SIZE)

[jdoc1949]

I have finally found really good condition 19" "rotors" kind two colors, sliver edges and dark Charcoal
BLADES they are 9" Width and 19"D with E33.

So question what width, I am getting 265/255/245 Either with x40 h x19" dia. 265 makes it .15mph faster and 245 a bit smaller.

I have ridden in one with 255/35/19 on highway, to rough, thats why Im going 40 high
I want the wheel well to look fuller, wider better for saving wheel edges and better grip. So what width is going to look best and give best grip.
It has just come out off warrantee so Im doing a few things.
Larger intake radiator,
KN filter,
Larger inlet out hoses on turbo

I have a stage 1 tune Im going to program
034 sway bars
Dont want to use 034 there springs its to low (its to much)
I think just stiffening up the car would be first suspension first
