2024 Subaru Outback — Tire Size & Pressure

Quick answer

• OEM tire sizes (most common): 225/65R17 (Base, Premium, Wilderness) or 225/60R18 (Limited, Touring, Onyx, XT trims)
• Recommended cold tire pressure (door placard): typically 35 psi front / 35 psi rear; some trims show 33–36 psi F/R. Always follow your specific door placard.
• Bolt pattern: 5x114.3 mm (5x4.5")
• Wheel size and offset: 17x7J or 18x7J; typical offset +48 to +55 mm; hub bore 56.1 mm
• Load index / speed rating (OEM range): 99–102 load index; H–V on highway all-season (Wilderness often T-rated A/T)
• Spare tire size: compact temporary on most trims (varies by wheel package; commonly T135/80R17 or T145/80R18); Wilderness often equipped with a full-size 225/65R17
• TPMS sensor frequency: generally 433 MHz on 2024 Subaru Outback (verify before ordering sensors)

Tire sizes by trim

Notes:

• Offsets across trims are commonly +48 to +55 mm. Wilderness wheels may sit slightly differently but remain within this range. Always confirm clearance and hub-centric fitment (56.1 mm) if changing wheels.
• Some trims may list alternative spare sizes; check the jack storage label or owner’s manual.

Recommended replacement tires

• Premium all-weather: Michelin CrossClimate 2 (price: premium). Outstanding wet, snow, and dry grip with SUV sizes available for 225/60R18 and 225/65R17.
• Premium touring all-season: Continental CrossContact LX25 or PureContact LS (price: upper mid). Quiet ride, strong tread life, and confident wet traction.
• Value touring all-season: General Altimax RT45 or Kumho Crugen HP71 (price: value). Solid everyday performance for budget-conscious owners.
• All-terrain (Wilderness or light trail use): Yokohama Geolandar A/T G015 or Falken Wildpeak A/T Trail (price: mid). Road-mannered A/T choices that fit 225/65R17 with 3PMSF options.
• Dedicated winter: Bridgestone Blizzak WS90 or Michelin X-Ice Snow (price: premium seasonal). Consider a 17" winter set for trims that ship with 18" wheels to improve winter compliance and cost.

Tip: Match or exceed the OEM load index and speed rating shown on your door placard. For Outback, that’s commonly LI 99–102 and H–V (T on some A/T).

When to inflate to max load psi (HD trucks only)

This guidance does not apply to the Subaru Outback. Do not inflate passenger-vehicle tires to the sidewall “max pressure” unless directed by the manufacturer. For Outback models, use the door placard pressure (typically 35 psi F/R, or within the 33–36 psi range shown on certain trims). Increase pressures modestly only when carrying heavier loads within GVWR and never exceed the tire’s sidewall maximum.

Lug nut torque & pattern

• Pattern: 5-lug, 5x114.3 mm
• Lug nut thread: M12 x 1.25
• Torque: 88–90 ft-lb (120 N·m typical). Retorque after 50–100 miles following wheel or tire service.

Additional wheel fitment notes

• OEM wheel sizes: 17x7J or 18x7J
• Typical offset range: +48 to +55 mm
• Hub bore: 56.1 mm (use hub-centric rings if running aftermarket wheels with larger bores)
• Plus-sizing: A common upgrade on 17" trims is 18" wheels with 225/60R18. If downsizing from 18" to 17" for winter, use 225/65R17 to maintain overall diameter.

Common tire issues for this vehicle

• Cupping/feathering on all-wheel-drive vehicles: Irregular wear can develop if rotations are skipped. Rotate every 6,000–7,500 miles and keep pressures at placard values.
• Inside shoulder wear: Can occur from alignment drift, curb strikes, or aggressive cornering. Have alignment checked annually or after impacts.
• A/T tire noise (Wilderness): Aggressive tread patterns can hum as they wear; maintain rotations and proper inflation to minimize.
• Hydroplaning resistance: The Outback is competent in rain, but worn tires lose wet grip quickly. Replace near 4/32" for wet performance and 5/32" if you drive in snow.
• TPMS service: 2024 models generally use 433 MHz sensors. When adding a second wheel set (e.g., winters), program or clone sensors to avoid warning lights.

Always confirm your exact door placard for tire size, load index/speed rating, and cold inflation.
