    275/40R18?

    Hey guys!

    I was just wondering if anyone is running 275/40R18 on their S4. If so, do you have any tips for making them fit well? I am in the market for a new set of wheels and tires, and if anyone is running this tire size, some pics of the setup would be greatly appreciated.

    Unsure they will fit? Front calipers might rub. I haven't seen anyone running 18's... I have 19x9.5 +25 offset and have 275/35 Michelin's. They fit but needed all the camber I could get once modestly lowered.

    That size tire is too tall, wont work. I have seen one guy use 275/30/19, which is shorter than factory. Requires a really high offset wheel

    Not sure about the width, but 18's should fit over the calipers no problem. I use some old 18" RS4 replica wheels as winters and they fit fine.

    I'm running 245/40/R18 OEM wheels and tires and they fit fine over the calipers. I plan on upgrading my wheels in a few year and would also like to run a wider setup, the 40 series sidewall is great for ride quality which I appreciate and won't give up, so I'm sticking with 18s. I don't think I'd go wider than 255 though, 275s seem crazy wide lol.
