Advan Advan-Racing RZII 18x10.5 +15 specs

The wheels are 18-inch in diameter and 10.5 inches wide with a +15 offset, in the 5x114.3 bolt pattern the Subaru WRX STI uses.

A +15 offset on a 10.5-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.

Advan Advan-Racing RZII 18x10.5 +15 on a Subaru WRX STI is a common WRX STI question, and this page shows exactly how it sits, how it clears, and what the owner changed to make it work.

225/35R18 tires on 18x10.5 wheels

The tire size is 225/35R18: a 225 mm section width with a 35 aspect ratio on the 18-inch wheel, which gives a stretched fit (the tire is narrower than the wheel, which pulls the sidewall in and helps clear the fender).

The owner chose Hankook Ventus V12 EVO2 K120. We stock Yokohama YOK Advan Fleva 225/35R18XL at $281 each in this size, and other 225/35R18 tires through the 225/35R18 tire search.

Searching for 225/35R18 tires on a Subaru WRX STI, or the right tire size for 18x10.5 +15 wheels? This is one owner's proven combination, and every wheel and tire package we sell ships mounted, balanced and ready to bolt on.

Suspension, stance and clearance

It rides on Air Lift Performance air suspension, so it can lay low parked and raise up to drive.

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 Subaru WRX STI comes down to the offset and width above; copy them and you get the same result.
