How long can you drive on a spare tire Subaru Outback?
In most Subaru Outback models, the spare is a compact temporary spare designed for emergency use. It should only be driven to the nearest service location and not used for long trips. The usual limit is about 50 miles (80 kilometers) at speeds up to 50 mph (80 km/h). Some models or markets may use a tire repair kit instead, which has its own usage instructions.
Spare setups in the Outback
The Outback's spare configuration has evolved over years and across markets. The common setup is a temporary donut wheel. In some trims or regions, Subaru ships a sealant-and-compressor repair kit instead of a spare wheel. Always verify with your owner's manual or the placard in the cargo area for your exact model.
Temporary spare vs repair kit
A temporary spare is a smaller-diameter wheel designed to get you to a place where you can repair or replace a tire. It typically carries a speed and distance limit. A tire repair kit uses sealant and an air compressor to temporarily seal a puncture and inflate the tire, but does not restore a damaged tire and should be used only as a stopgap.
Here are the standard driving limits most Outback spare configurations require:
- Distance: Do not exceed about 50 miles (80 kilometers) from the point of setup to reach a repair facility.
- Speed: Do not exceed 50 mph (80 km/h). Higher speeds stress the wheel and tire and can affect handling.
- Handling: Expect reduced traction, braking, and steering responsiveness; adjust driving style accordingly and leave extra space to other vehicles.
- Inflation: Inflate the spare to the pressure specified on its sidewall or in the owner's manual; do not assume standard road pressures apply.
These figures are general guidelines. For exact numbers that apply to your particular Outback model year and market, consult the owner’s manual and the tire placard in the cargo area or door jamb.
What to do if you must drive on a spare
If you find yourself with a spare installed, follow these steps to stay safe and avoid unnecessary wear on the spare and the vehicle:
- Limit your trip to the nearest tire shop or repair facility; arrange for a proper tire repair or replacement as soon as possible.
- Ensure the spare is properly mounted and the lug nuts are tightened to the manufacturer's torque specification with the correct pattern sequence.
- Keep speed under the recommended limit (typically 50 mph) and avoid highway merging or aggressive driving.
- Watch for adverse road conditions (wet, icy, or rocky surfaces) and drive more slowly than usual with ample following distance.
- Get the damaged tire inspected; even if you repair with sealant, you may need a replacement tire or wheel. If your spare is a full-size type, treat it with normal care, but still service the original tire promptly.
In all cases, a spare is a temporary solution meant to bridge you to professional service. Do not rely on it for extended periods or in severe driving conditions.
Summary
For Subaru Outback models with a compact donut spare, the common guideline is about 50 miles at up to 50 mph. If your Outback uses a tire repair kit instead, follow the kit’s instructions and seek tire service promptly. Always verify the exact figures in your owner’s manual, and treat the spare as a temporary fix rather than a long-term tire solution.
