How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
Subaru Outback OE Wheel Specs
The 2025 Subaru Outback (Midsize Crossover Wagon) uses a 5x114.3 bolt pattern with a 56.1mm center bore. Factory wheels are 18x7.0J at ET48 offset, front and rear.
Why the factory spec works for most owners:
- Supports the vehicle's curb weight and load capacity
- Preserves ground clearance for everyday and light off-road use
- Balances ride comfort with cargo and passenger stability
- Maintains clearance for the factory suspension travel and brake package
Flush Fitment
For a flush look, a 18x8.5J wheel at ET45 offset (front and rear) is a commonly used starting point — clearance must be verified on a stock or mildly lowered Subaru Outback.
Maximum Aggressive Fitment
18x9.0J at ET40 offset is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: 18x7.0J ET48 → ~5.89\" backspacing
- Flush: 18x8.5J ET45 → ~6.52\" backspacing
- Max: 18x9.0J ET40 → ~6.57\" backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or can't find your exact Subaru spec, or want a wheel built to a custom offset for your Subaru Outback? Contact ANKUSI with your bolt pattern and offset target and we'll confirm the correct forged wheel spec for your build.
