2015 Lexus IS350

2015 Lexus IS350 wheel fitment at a glance

This 2015 Lexus IS350 is running Rotiform KPS, staggered: 20x8.5 +30 up front and 20x9.5 +35 in the rear, wrapped in 225/35R20 front and 235/30R20 rear Crusade SXT tires.

It sits on BC Coilovers coilovers with a flush stance, meaning the wheel face lines up with the fender.

If you are searching for Lexus IS350 wheel fitment, Rotiform KPS on a Lexus IS350, 20x8.5 +30 wheels on a IS350, or what tire size goes with that setup, this build is a real-world answer, photographed and measured by the owner.

Rotiform KPS 20x8.5 +30 specs (staggered)

The wheels are 20-inch in diameter and 8.5 inches wide with a +30 offset up front, and 20-inch by 9.5 inches at +35 in the rear, in the 5x120 bolt pattern the Lexus IS350 uses.

A +30 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 +35 offset on the 9.5-inch wheel keeps the rear in line with the front.

225/35R20 / 235/30R20 tires on 20x8.5 wheels

The tire size is 225/35R20 front and 235/30R20 rear: a 225 mm section width with a 35 aspect ratio on the 20-inch wheel, which gives a square fit (tire and wheel are about the same width, the clean look most people go for).

The owner chose Crusade SXT. We stock Lexani LX-TWENTY 225/35R20 at $100 each in this size, and other 225/35R20 tires through the 225/35R20 tire search.

The car is lowered on BC Coilovers coilovers, which lets the owner dial in ride height and camber to clear 20x8.5 +30 and get the flush look.

No rubbing at all, front or rear, no spacers, no fender work. That means the setup fits as-is, which is what most owners want to know before they buy.
