Subaru Legacy BN, 6th gen wheel fitment

The sixth-generation Legacy left the factory on narrow 7 to 7.5-inch wheels with high offsets, so owners usually go wider at 18 or 19 inches to fill the arches. WRX and STI wheels are a popular swap because this generation moved to the same 5x114.3 bolt pattern.

5x114.3 bolt pattern · 56.1 mm centre bore · Stock wheels: 17 × 7.5, 17 × 7, 18 × 7.5 inch · Stock tyres: 225/55 R17, 225/50 R18

Width and offset guidance

Offset range

Check the exact setup

There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.

Common width limit

Measure before ordering

A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.

These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.

Clearance notes

The 2010–2014 fifth-generation Legacy uses 5x100, so its wheels do not fit the BN without adapters.
The hub bore is 56.1 mm. Most aftermarket 5x114.3 wheels have a larger bore and need hub-centric rings.
Owners in the LegacyGT wheel thread warn that a 245/40 R18 tyre is undersized for this car and makes the speedometer over-read. 245/45 R18 stays closer to the factory diameter.
The same thread advises against fitting 245 tyres to the factory 7.5-inch rims; 235 is about the widest that suits that width.
Parts catalogues list both 17x7 and 17x7.5 ET55 alloys for the 2.5i and Premium, so check your existing wheels before ordering winter tyres or spacers.
Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.
