Subaru Outback models from 2015 onwards feature a bolt pattern of 5×114.3mm (5×4.5 inches), with a center bore of 56.1mm (2.20 inches), and utilize five lug nuts with a thread size of M12 x 1.25. These lug nuts require a torque of 120Nm (88.5 lb-ft). Earlier models, specifically from 1995 to 2014, share the same center bore and lug nut specifications but differ in bolt pattern, which is 5x100mm (5×3.94 inches).
Key Takeaways:
- Understanding Bolt Patterns: Models post-2015 use a 5×114.3mm pattern, while those between 1995-2014 have a 5x100mm pattern. This knowledge is crucial for wheel compatibility.
- Optimal Tire and Rim Selection: Different models have specific tire and rim requirements, such as the 2020-2022 2.4T’s 225/60R18 tires and 7Jx18 ET55 rims. Correct sizing ensures a smoother ride.
- Precision in Lug Nut Tightening: Adhering to the crisscross pattern and applying the correct torque (usually 88.5 lb-ft) is vital for wheel security.
- Regular Maintenance Checks: Rechecking lug nuts after the first 30 miles and periodically afterward ensures lasting wheel performance and safety.
- Model-Specific Wheel Details: Always refer to your specific model’s manual or consult a professional for accurate wheel specifications to maintain the integrity of your Subaru Outback’s performance.

Proper Lug Nut Tightening and Wheel Care
Lug Nut Tightening Procedure
Following the correct pattern when tightening the lug nuts on your Subaru Outback is crucial. Using a wheel wrench, begin by tightening the nuts halfway in a crisscross pattern. In the second round, apply the full torque as specified for your model. For most recent models, this is 88.5 lb-ft.
Checking and Retightening
After driving for approximately 30 miles (48 kilometers), it’s advisable to recheck the lug nuts for proper tightness. If they have loosened, retighten them to the specified torque. Regular checks are essential for maintaining wheel safety and performance.
