If you are searching for Mazda RX-8 wheel fitment, Rota Wheels P45-R on a Mazda RX-8, 18x9.5 +30 wheels on a RX-8, or what tire size goes with that setup, this build is a real-world answer, photographed and measured by the owner.

Rota Wheels P45-R 18x9.5 +30 specs (staggered)

The wheels are 18-inch in diameter and 9.5 inches wide with a +30 offset up front, and 18-inch by 9.5 inches at +20 in the rear.

A +30 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 rear +20 offset on the 9.5-inch wheel pushes the rear out further for the staggered look.

245/40R18 / 255/35R18 tires on 18x9.5 wheels

The tire size is 245/40R18 front and 255/35R18 rear: a 245 mm section width with a 40 aspect ratio on the 18-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 Hankook RS-3. We stock Ironman IRON iMOVE Gen 3 AS 245/40ZR18XL at $101 each in this size, and other 245/40R18 tires through the 245/40R18 tire search.

Suspension, stance and clearance

This Mazda RX-8 is on stock suspension, so the ride height is factory and the fitment you see here works without lowering the car.

No rubbing at all, front or rear, no spacers, rolled fenders. Rolling or pulling the fender is what most owners do once the wheel sits this close; it keeps the tire from catching the lip over bumps.

Stance: flush. The wheel face lines up with the fender. Flush fitment on a Mazda RX-8 comes down to the offset and width above; copy them and you get the same result.
