What size tires are on a Subaru Impreza hatchback?
The tire size for a Subaru Impreza hatchback isn’t fixed across all years and trims. In general, you’ll commonly see 205/55R16 on 16-inch wheels or 205/50R17 on 17-inch wheels, but the exact size varies by model year and equipment. Always verify your specific vehicle’s size on the door placard or in the owner’s manual.
The Impreza hatchback has offered multiple wheel options across generations, and tire sizes can change with updates or different trims. The most reliable way to know your exact stock size is to read the placard on the driver’s door jamb, consult the owner’s manual, or look up your vehicle’s VIN with Subaru’s official documentation.
How to find the exact size on your car
Use these steps to determine the correct tire size for your specific Impreza hatchback.
- Check the driver's door jamb placard for a line labeled Tire Size that lists the recommended size for both front and rear tires.
- Inspect the sidewall of any current tire for the size notation, typically shown as P205/55R16 (or a similar format).
- Consult the owner's manual or the window sticker (Monroney) for the original equipment tire specification.
- If in doubt, contact a Subaru dealer or use your VIN to pull the exact factory build sheet and original tire size.
Knowing the exact size helps ensure you install the correct tires and maintain safety, handling, and fuel economy.
Understanding tire size notation
How the size breaks down
Tire sizes follow a standard format that includes width, aspect ratio, construction, and wheel diameter. This helps you read the numbers on the tire and choose compatible replacements.
- Example formats you may see: P205/55R16, 205/50R17, or 205/60R16, where 205 is width in millimeters, 55 is the aspect ratio (height as a percentage of width), R indicates radial construction, and 16 is the wheel diameter in inches.
- Some Impreza variations use different prefixes (P vs LT) and may include a load index and speed rating after the size (e.g., 205/55R16 91V).
Correct interpretation helps you match the replacement tires to the car’s performance and safety specifications.
What to consider when replacing tires
When selecting tires, align with Subaru’s recommendations and consider your driving conditions, climate, and performance preferences.
- Always aim to replace with the same size as the original equipment or a size within Subaru's approved range for your model year and trim.
- Check the load index and speed rating to ensure safety and proper performance for your vehicle.
- Consider all-season tires for year-round use, or winter tires in cold climates; avoid mismatched sizes if you drive in challenging conditions.
- After installing new tires, ensure proper wheel alignment and tire rotation to maximize life and handling.
- Ensure the TPMS (tire pressure monitoring system) sensors are compatible or reset after installation.
The most reliable approach is to start with the original equipment size listed on your car’s placard or owner’s manual and consult a professional for any deviations.
Summary
There is no single tire size that fits every Subaru Impreza hatchback. The size depends on the model year, trim level, and wheel option. Always verify using the door placard, the owner’s manual, or Subaru’s VIN-based documentation, and follow manufacturer guidelines when replacing tires.
