Aftermarket 20x9 +18 / 20x8.5 +48 275/65R20 Lift kit Hellaflush stance
2022 Rivian R1T
This 2022 Rivian R1T is running Aftermarket, staggered: 20x9 +18 up front and 20x8.5 +48 in the rear, wrapped in 275/65R20 tires.
It sits on lift kit with a hellaflush stance, meaning the wheel face sits at or just past the fender, the most aggressive look.
If you are searching for Rivian R1T wheel fitment, Aftermarket on a Rivian R1T, 20x9 +18 wheels on a R1T, or what tire size goes with that setup, this build is a real-world answer, photographed and measured by the owner.
The wheels are 20-inch in diameter and 9 inches wide with a +18 offset up front, and 20-inch by 8.5 inches at +48 in the rear.
A +18 offset on a 9-inch wide wheel puts the wheel face in an aggressive position close to the fender. Lower offset moves the wheel outward; higher offset tucks it in. The rear +48 offset on the 8.5-inch wheel keeps the rear in line with the front.
Aftermarket 20x9 +18 on a Rivian R1T is a common R1T 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 275/65R20: a 275 mm section width with a 65 aspect ratio on the 20-inch wheel, which gives a meaty fit (the tire is wider than the wheel, so the sidewall bulges a little and gives more cushion).
We stock Arroyo Tamarock AT LT275/65R20 at $262 each in 275/65R20, and more 275/65R20 tires through the tire search.
