This 2019 Audi S4 is running BCF RS31 in 19x9.5 +40 at all four corners, wrapped in 265/35R19 tires.

If you are searching for Audi S4 wheel fitment, BCF RS31 on a Audi S4, 19x9.5 +40 wheels on a S4, or what tire size goes with that setup, this build is a real-world answer, photographed and measured by the owner.
The wheels are 19-inch in diameter and 9.5 inches wide with a +40 offset.
A +40 offset on a 9.5-inch wide wheel puts the wheel face in a mild push toward the fender. Lower offset moves the wheel outward; higher offset tucks it in.

The tire size is 265/35R19: a 265 mm section width with a 35 aspect ratio on the 19-inch wheel, which gives a meaty fit (the tire is wider than the wheel, so the sidewall bulges a little and gives more cushion).
