2009 Subaru Tire Fitment Guide

2009 Subaru vehicles use eight tire sizes across three model lines: 205/50R17, 205/55R16, 225/45R17, and 245/40R18 for the Impreza; 205/50R17, 215/45R17, and 215/45R18 for the Legacy; and 225/60R16 plus 225/55R17 for the Outback. The only shared size across more than one model is 205/50R17, which fits both Impreza and Legacy applications. Rim diameters span 16, 17, and 18 inches depending on the model and wheel package.

That means the first step is identifying not only your 2009 Subaru model, but also the wheel diameter currently on the car. If you are comparing tires across trims, pay close attention to whether your Subaru uses a 16-, 17-, or 18-inch wheel, because the tire size families are not interchangeable simply because they belong to the same year and make.

On a 2009 Subaru tire, 205/50R17 means the tire is 205 millimeters wide, has a 50-series aspect ratio, uses radial construction, and mounts on a 17-inch wheel. Within the 2009 Subaru range, that size appears on both Impreza and Legacy applications. Available examples come in blackwall and wide whitewall form, with speed ratings that vary by product between W and Y.

For a buyer, the key point is that 205/50R17 is not just a measurement; it also places the tire in a specific 17-inch wheel package used on two different Subaru model lines. If your car already has 17-inch wheels and the sidewall calls for 205/50R17, you can then compare brand, sidewall appearance, and rating details without changing the basic fitment.

No. 2009 Subaru models do not share one universal tire size. The Impreza alone uses four sizes, the Legacy uses three, and the Outback uses two, with only 205/50R17 crossing between model lines. Every other size is specific to one model family, and the overall spread includes 16-, 17-, and 18-inch wheel fitments.

That model-by-model variation matters because Subaru positioned these vehicles differently. An Outback's taller-profile tire choice serves a different purpose from an Impreza or Legacy low-profile sport fitment, even when the year and make are the same. If you are unsure, check the sidewall on the tires currently mounted and compare it with the wheel diameter before moving on to brand or style selection.

Sidewall style depends heavily on size for 2009 Subaru applications. Several Impreza and Legacy sizes are available strictly as blackwalls, including 205/55R16, 225/45R17, 245/40R18, 215/45R17, and 215/45R18. The shared 205/50R17 size adds a wide whitewall option alongside blackwall, while Outback sizes open the broadest cosmetic range: 225/60R16 can be found in raised yellow letter, redline, pin white stripe, and wide whitewall, and 225/55R17 is available in blackwall and wide whitewall.

For most 2009 Subaru owners, blackwall remains the most natural visual fit because it matches the era and the original mainstream appearance of these cars. The whitewall, stripe, and lettered options are more of a custom-look choice than a factory-style one for a 2009 Subaru. If appearance matters as much as fitment, narrow the decision by size first, then choose the sidewall treatment that matches the look you want.

BFGoodrich covers the largest share of 2009 Subaru sizes, with fitments across every model line. Other brand coverage depends on the size: American Classic appears in 205/50R17, Michelin appears in 205/55R16, Nitto appears in 225/45R17 and 245/40R18, M&H Racemaster appears in 245/40R18, and Goodyear appears in 225/60R16. Brand choice is therefore tied closely to the exact size on your Subaru rather than to the make alone.

That matters because one owner may have several brands to consider while another may only have one or two within the correct size. An Impreza on 245/40R18 has a different brand mix from an Outback on 225/60R16, even though both are 2009 Subarus. Once your size is confirmed, compare the available brands by sidewall style, load figures, and speed ratings instead of assuming every brand covers every model.

For several 2009 Subaru sizes, both BFGoodrich g-Force Sport COMP-2 and BFGoodrich g-Force COMP-2 A/S are available in the same fitment family. In shared sizes such as 205/50R17, 205/55R16, 225/45R17, 245/40R18, and 215/45R17, they remain blackwall radials with similar rim-width compatibility, but the exact load index and weight can differ by size. For example, in 245/40R18 the COMP-2 A/S carries a 97Y XL marking while the Sport COMP-2 appears as 93W.

The practical takeaway is to compare the exact sidewall marking in your chosen size rather than choosing by series name alone. Two tires may look closely related at a glance yet carry different speed letters, load indexes, or XL markings once you get into the specific Subaru fitment. That sidewall-level comparison is especially important on 17- and 18-inch applications where profile and rating details can matter more than brand familiarity.

Rim-width compatibility varies by size on 2009 Subaru applications. The 205/50R17 and 205/55R16 sizes commonly fit 5.5- to 7.5-inch rims, 225/45R17 generally falls around 7.0- to 8.5-inch fitment, and 245/40R18 works around 8.0- to 9.5-inch rims, with one drag-oriented application at 8.5 inches. Legacy-specific 215/45R17 and 215/45R18 sizes center around 7.0- to 8.0-inch rims, while Outback sizes span wider recommendations, including 225/60R16 at 6.0- to 9.0-inch rims and 225/55R17 at 6.0- to 9.0 inches depending on the product.

Those ranges show why wheel width matters almost as much as tire size. Two tires may share the same nominal size but still have slightly different approved rim-width windows depending on the series. Before mounting a replacement, verify the actual wheel width on your Subaru so the tire sits correctly on the rim and retains the profile intended by the manufacturer.

Most 2009 Subaru fitments here are modern radial applications, and tubeless marking appears on some products, such as a Michelin 205/55ZR16 91Y TL and a BFGoodrich 245/40ZR18 97Y XLTL. At the same time, not every product in those sizes carries the same sidewall notation, so tube status can vary by product rather than being expressed the same way across an entire size family. No 2009 Subaru size here is presented as a tube-type-only fitment.

For that reason, the safest approach is to match your decision to the exact tire you plan to use rather than treating all tires in the same size as identical. If your Subaru still uses its original-style wheels, valve stems, or specialty wheels, confirm the tire's sidewall marking and wheel compatibility before installation. That quick check prevents confusion when two products in the same size use different notation.

A 2009 Subaru should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can accelerate sidewall aging. Keep the tires inflated to the pressure appropriate for the car's load and use, and move the vehicle periodically so one section of tread is not carrying the same weight for months at a time. Radials generally tolerate storage well, but they still age from time, heat, and environment even when mileage stays low.

If the Subaru will sit through a full season or longer, clean the tires, avoid parking on damp soil, and consider reducing long-term static load with proper stands if the storage plan is extensive. Collector-car storage is easiest on tires when the environment stays stable and the car is not left half-flat. A little storage discipline goes a long way toward preserving ride quality and sidewall condition.

For a 2009 Subaru that sees collector, enthusiast, or irregular-use driving, tire life should be judged more by age than tread wear. A good rule is to begin inspecting age more critically once a tire reaches the five- to seven-year range and to treat around ten years as the point where replacement deserves serious consideration, even if the tread still looks serviceable. The DOT date code on the sidewall is the best starting point for that evaluation.

That age-based approach matters because many enthusiast cars accumulate miles slowly, and tires can appear healthy while the rubber has already hardened or begun to degrade internally. If your 2009 Subaru still wears older tires from a lightly used period of ownership, do not let tread depth alone guide the decision. Sidewall condition, pressure retention, and manufacture date together tell the fuller story.

Tires on a 2009 Subaru should be checked before every drive and again before any longer highway outing. Look for visible cracking, cuts, punctures, bulges, uneven wear, and pressure loss, and make sure the tread surface remains even from shoulder to shoulder. Because some products in these Subaru sizes use explicit tubeless notation while others vary in marking, valve stems and bead sealing are worth inspecting closely during routine service.

Regular inspection is especially important on cars that alternate between daily use and long periods of sitting. A Subaru that feels normal around town can still reveal pressure or aging issues once it is loaded for a trip or driven at sustained speed. Catching a worn valve stem, damaged shoulder, or slow leak early is far easier than dealing with it after the car is already on the road.

A 2009 Subaru Impreza would have originally used modern radial tires, not bias-ply or antique constructions. Within the 2009 Impreza range, the applicable sizes are 205/50R17, 205/55R16, 225/45R17, and 245/40R18 depending on the exact model and wheel package. Those sizes reflect Subaru's modern compact-car approach at the time, with both standard-profile and lower-profile performance-oriented fitments appearing across the range.

Original-equipment brand can vary by market, trim, and production run, so the most important authenticity point is usually getting the correct size, wheel diameter, and overall look for your particular Impreza. If you are restoring a specific trim to factory-style appearance, compare the car's placard, handbook, and surviving original photos, then cross-check with marque forums or Subaru specialists before settling on a sidewall style or replacement series.

Yes, correct tire fitment matters on a 2009 Subaru when the goal is factory-style presentation or judged authenticity. On a modern-era Subaru, judges and informed enthusiasts are more likely to notice incorrect size, wheel diameter mismatch, or an out-of-character sidewall treatment than to focus on an exact replacement brand. A blackwall radial in the proper size generally aligns more closely with how these cars appeared when new than a custom whitewall, redline, or raised-letter treatment.

That does not mean alternate sidewall styles are wrong for every owner; it means they read as customization rather than strict originality on a 2009 Subaru. If the car will be shown in marque events or preservation-oriented classes, keep the size and overall visual character close to factory practice. Event-specific standards can vary, so Subaru clubs and model-specific enthusiast groups remain the best reference for judging expectations.

In 225/60R16 for the 2009 Subaru Outback, BFGoodrich Silvertown Radial and Goodyear Eagle NASCAR take the same size in very different visual directions. The Goodyear appears with a raised yellow letter sidewall, a 6.0- to 7.0-inch rim-width range, and a 1,609-pound load figure at 44 psi. BFGoodrich Silvertown Radial appears in redline, pin white stripe, and wide whitewall versions, with a broader 6.00- to 9.00-inch rim-width range and load figures reaching 1,609 pounds depending on the version.

For an Outback owner, that makes the choice primarily about appearance and wheel compatibility rather than about basic size. The Goodyear creates a more overtly lettered performance look, while the BFGoodrich family offers several vintage-style custom sidewall treatments. Since neither presentation is typical factory-appearance territory for a 2009 Outback, authenticity-minded owners will usually lean toward a blackwall-style look in the correct size, while custom builds may favor the more expressive options.

Yes, these 2009 Subaru tire sizes are highway-capable modern radials, and where speed symbols are present they are substantial. W-rated products carry a 168 mph ceiling and Y-rated products carry a 186+ mph ceiling, depending on the exact size and series. Those figures exceed normal legal highway use by a wide margin, so in everyday driving the condition of the tire and the mechanical state of the Subaru matter far more than the raw speed symbol alone.

The practical point is that highway safety starts with matching the tire to the correct size, maintaining proper inflation, and making sure the suspension, alignment, and brakes are in sound order. A 2009 Subaru in good condition on fresh, correctly sized radials can be a very capable road car. An older or neglected Subaru on aged tires should be inspected carefully before any sustained-speed travel, regardless of what the sidewall rating says.

Inflation pressure on a 2009 Subaru should follow the vehicle's factory recommendation first, with the tire maker's sidewall information used to understand the tire's maximum-rated load and pressure. Several 2009 Subaru sizes here include load-and-pressure references such as 1,279 at 51 psi, 1,433 at 50 psi, 1,609 at 44 psi, 1,609 at 50 psi, and 1,819 pounds at 50 psi depending on the exact size and product. Those numbers are maximum load references, not a universal cold inflation target for every Subaru.

That distinction is important because the right running pressure for a Legacy, Impreza, or Outback depends on the specific car, axle load, and intended use. Do not transfer a pressure figure from one Subaru size to another just because the brand matches. Check the door-jamb placard or owner's manual for the car, then confirm that the tire selected has the correct load capacity for the application.

Before taking a 2009 Subaru on a longer drive, inspect all four tires and the spare for cracking, cuts, bulges, embedded debris, and uneven wear. Verify cold pressures, make sure the tread depth is consistent across the axle, and inspect the valve stems for age or damage. On sizes where sidewall notation varies by product, also confirm the exact tire type and condition of the wheel sealing surfaces during service.

A longer drive is also the right time to look beyond the tires themselves. Subarus of this era reward a full pre-trip check that includes alignment condition, brake feel, wheel-bearing noise, and suspension behavior, especially if the car has been sitting or only used locally. Tires are the first point of contact with the road, but they work best when the rest of the chassis is equally ready for the trip.
