This 2022 Cadillac CT4 is running RRSW Boost in 18x8 +35 at all four corners, wrapped in 245/40R18 tires.

If you are searching for Cadillac CT4 wheel fitment, RRSW Boost on a Cadillac CT4, 18x8 +35 wheels on a CT4, or what tire size goes with that setup, this build is a real-world answer, photographed and measured by the owner.
The wheels are 18-inch in diameter and 8 inches wide with a +35 offset.
A +35 offset on a 8-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.
RRSW Boost 18x8 +35 on a Cadillac CT4 is a common CT4 question, and this page shows exactly how it sits, how it clears, and what the owner changed to make it work.
The tire size is 245/40R18: a 245 mm section width with a 40 aspect ratio on the 18-inch wheel, which gives a meaty fit (the tire is wider than the wheel, so the sidewall bulges a little and gives more cushion).
