Wheel advice needed - TTRS - 20 inches

I had the misfortune of denting two of my OEM rotor wheels in one single day. These are my summer wheels, so they're coming off in about a week, so this isn't a rush.

I'm looking at getting new wheels, maybe 20 inches. My questions are :

- What tires do i need to keep everything as oem as possible? 255-30-20 ? or 35-20? Currently, they're 255-35-19
- Any wheel recommendations?
- I'd need a wheel/tire set that is straight bolt on. No spacers or anything. I had that on my jetta back in the day and nothing but headaches.
- I have no idea what the new in styles are
- I have no idea about offsets
- I already bought OEM wheels from Audi for winter. Not doing that mistake again
- Weight isnt that much of a concern to me, but the lighter the better.

obligatory pic of the car to get an idea of the colour. This is when Joey cleaned her up real nice



Thanks much in advance!

living in Mtl I would stay with 19"

and 20" doesnt look right on a TT unless youre slammed. You will also rolling on bandaid tires.. not worth it
