If you are searching for Lexus IS300 wheel fitment, Lumarai Morro on a Lexus IS300, 20x8.5 +37 wheels on a IS300, or what tire size goes with that setup, this build is a real-world answer, photographed and measured by the owner.

Lumarai Morro 20x8.5 +37 specs (staggered)

The wheels are 20-inch in diameter and 8.5 inches wide with a +37 offset up front, and 20-inch by 10 inches at +44 in the rear.

A +37 offset on a 8.5-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 rear +44 offset on the 10-inch wheel keeps the rear in line with the front.
