The 2010 Subaru Legacy marked a major redesign year, giving Subaru’s midsize sedan a broader, more refined presence while keeping the brand’s all-weather, all-wheel-drive identity front and center. That matters when choosing tires, because this Legacy does not use a single size across the board. Depending on sub-model, it runs 205/60R16, 215/50R17, 225/50R17, or 225/45R18, and all are radial fitments. Available choices range from traditional blackwall performance-oriented tires to a wide whitewall option in 205/60R16. The right pick starts with the exact trim and wheel diameter, then moves to appearance, driving use, and overall fitment consistency.
Which Tire Size Is Right for The 2010 Subaru Legacy
The 2010 Subaru Legacy uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Fitment varies across 16-inch, 17-inch, and 18-inch rims, so the first step is confirming the trim and the wheels currently on the car. Once that is settled, the decision becomes choosing the right radial tire within that size, whether the priority is everyday road use, a sportier feel, or a distinct sidewall appearance.
Fit(s): 2.5GT Limited Sedan (Summer Tires) and 2.5GT Premium Sedan (Summer Tires)
Construction: Radial|Rim: 18 in
225/45R18 is a modern metric radial size in which 225 is the section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2010 Subaru Legacy, this size is used on specific 18-inch summer-tire sub-models, making wheel confirmation especially important. Available choices include BFGoodrich and Nitto blackwall tires across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This size suits buyers who need to stay with the Legacy’s larger-wheel fitment and compare sport-oriented product options carefully.
205/60R16 is a metric radial size that indicates a 205-millimeter section width, a 60-series profile, radial construction, and a 16-inch rim. For the 2010 Subaru Legacy, it serves as a primary fitment on certain 16-inch-wheel sub-models and keeps the focus on correct wheel diameter rather than performance-style upsizing. In this size, the available product uses an asymmetrical tread design with a 1.50-inch wide whitewall presentation. It is a useful choice for owners keeping the original 16-inch wheel setup and looking for a more distinctive sidewall appearance than a typical blackwall tire.
215/50R17 means a 215-millimeter section width, a 50-series aspect ratio, radial construction, and fitment on a 17-inch rim. On the 2010 Subaru Legacy, this size applies to a specific 17-inch sub-model, so it should not be treated as interchangeable with the other 17-inch Legacy size without checking the exact trim. Available tires are blackwall BFGoodrich offerings in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size is best evaluated by matching the existing wheel setup and then comparing series differences within the proper 17-inch fitment.
225/50R17 is a metric radial size with a 225-millimeter section width, a 50-series profile, and a 17-inch rim diameter. For the 2010 Subaru Legacy, this is the 17-inch fitment used on the 3.6R sub-model family, so it belongs to a different configuration than the 215/50R17 setup. Product choices include BFGoodrich and Nitto blackwall tires, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. This size is the right place to start for 3.6R owners who want to preserve the correct 17-inch specification while comparing available performance-oriented radial options.
Tire fitment on the 2010 Subaru Legacy varies by sub-model, so identifying the exact trim matters before selecting a tire. Some versions share the same size, but the Legacy range spans 16-inch, 17-inch, and 18-inch wheel fitments, which changes the available tire choices significantly.

2010 Subaru Legacy 2.5GT Limited Sedan (Summer Tires)
The 2010 Subaru Legacy 2.5GT Limited Sedan with summer tires uses the 225/45R18 radial size. That makes tire selection center on the 18-inch wheel setup and comparing blackwall performance-oriented options within the correct size.
2010 Subaru Legacy 2.5GT Premium Sedan (Summer Tires)
The 2010 Subaru Legacy 2.5GT Premium Sedan with summer tires also uses the 225/45R18 radial fitment. Buyers should confirm the 18-inch wheels remain on the car, then compare available series and brand choices in that size.
The 2010 Subaru Legacy 2.5i uses the 205/60R16 radial size. Tire selection here is more straightforward, with the main considerations being the 16-inch wheel fitment and whether the available sidewall presentation matches the look you want.
The 2010 Subaru Legacy 2.5i Limited uses the 215/50R17 radial size. Because another 17-inch Legacy fitment also exists, the practical step is confirming this exact sub-model before choosing among the available blackwall tire series.
The 2010 Subaru Legacy 2.5i Premium uses the same 205/60R16 radial size as the 2.5i. That keeps fitment simple as long as the 16-inch wheels are still in place, with the choice focused more on tire appearance than multiple product families.
The 2010 Subaru Legacy 3.6R uses the 225/50R17 radial size. Tire selection should stay centered on that 17-inch fitment, then move to comparing the available blackwall options from the brands and series offered in this size.
The 2010 Subaru Legacy 3.6R Limited also uses the 225/50R17 radial fitment. That means the main task is confirming the wheel setup and then narrowing the choice by brand and tire series rather than by alternate primary sizes.
The 2010 Subaru Legacy 3.6R Premium uses the 225/50R17 radial size as well. Owners should treat the selection process as a comparison among the available 17-inch blackwall tires, while checking that the car has not been changed to a different wheel package.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2010 Subaru Legacy Tires for Sale
Available 2010 Subaru Legacy tires vary by size, with BFGoodrich, Nitto, and American Classic options across several radial series. Most choices are blackwall performance-style tires, while 205/60R16 also includes a wide whitewall option for a more distinctive appearance.
These 2010 Subaru Legacy tire FAQs focus on the sizes used by each sub-model, the meaning of the metric size codes, wheel-diameter differences, product choices, and the fitment checks that matter before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2010 Subaru Legacy?
A 2010 Subaru Legacy can use four different tire sizes depending on sub-model: 205/60R16, 215/50R17, 225/50R17, and 225/45R18. All of these are radial sizes, and each one belongs to a specific Legacy configuration rather than the entire model line as a whole.
The most important step is matching the tire size to the exact trim and the wheels currently on the car. A Legacy with 16-inch wheels needs a different tire than one with 17-inch or 18-inch wheels, and even the two 17-inch fitments are not the same size. Checking the placard, existing tire size, and sub-model helps prevent ordering the wrong fitment.
What size rim does a 2010 Subaru Legacy use?
The 2010 Subaru Legacy uses three rim diameters across its tire fitments: 16-inch, 17-inch, and 18-inch. The 205/60R16 size fits a 16-inch rim, both 215/50R17 and 225/50R17 fit 17-inch rims, and 225/45R18 fits an 18-inch rim.
Rim diameter should be confirmed before anything else because a tire must match the wheel diameter exactly. It also helps to verify wheel width, especially if the car has aftermarket wheels, since product options in these Legacy sizes carry their own recommended rim-width ranges. The wheel and tire combination should be checked together rather than assuming every Legacy wheel setup is interchangeable.
Why does the 2010 Subaru Legacy have more than one tire size?
The 2010 Subaru Legacy has more than one tire size because the model range includes different sub-models with different wheel packages. The lineup spans 16-inch, 17-inch, and 18-inch fitments, and the tire size changes with those configurations rather than staying uniform across the entire Legacy family.
That means the correct tire is tied to the exact trim, not just the year and model name. A 2.5i may use a different size than a 2.5i Limited, 3.6R, or 2.5GT summer-tire sedan. Since many used cars have had wheel swaps over time, it is smart to confirm both the sub-model and the wheel diameter on the car before choosing a replacement tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Subaru Legacy?
Start with the correct size for the exact 2010 Subaru Legacy sub-model, then compare tires by construction, rim-width compatibility, sidewall style, and intended use. This Legacy uses radial tires only, but the available products vary from blackwall performance-style options to a wide whitewall choice in 205/60R16.
A careful selection also means matching the tire to the wheel setup actually on the car. The Legacy uses multiple rim diameters, and some sizes have several product lines while others are more limited. Once the size is confirmed, the decision becomes whether the priority is a traditional blackwall look, a more distinctive sidewall treatment, or a particular tire series within the proper fitment.
What sidewall styles are available for 2010 Subaru Legacy tires?
Sidewall style depends on tire size for the 2010 Subaru Legacy. Blackwall choices are available in 225/45R18, 215/50R17, and 225/50R17, while 205/60R16 includes a wide whitewall option. That gives some Legacy owners a more appearance-driven choice in addition to simple size matching.
The practical point is that sidewall style follows the available tires in each fitment, not just personal preference alone. An owner with a 16-inch-wheel Legacy may be able to choose a wide whitewall presentation, while the 17-inch and 18-inch fitments stay centered on blackwall products. Confirming the size first keeps appearance preferences from pulling the search toward a tire that does not match the wheel setup.
What brands offer tires for the 2010 Subaru Legacy?
Tires for the 2010 Subaru Legacy are available from BFGoodrich, Nitto, and American Classic, depending on size. BFGoodrich appears across several 17-inch and 18-inch fitments, Nitto is offered in select 17-inch and 18-inch sizes, and American Classic appears in the 205/60R16 fitment.
Brand choice should come after the correct size is established, because not every brand is offered in every Legacy fitment. It also helps to compare the tire series within each size, since one fitment may have several blackwall performance-oriented options while another may have a more appearance-focused tire. The brand question is really part of a larger size-and-application decision.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Subaru Legacy?
A period-style choice for a 2010 Subaru Legacy starts with the factory-size fitment for the exact sub-model, since the car used several different radial sizes. For a stock-appearing car, staying with the original wheel diameter and tire size usually preserves the overall stance and proportions better than mixing in a different Legacy fitment.
Appearance then comes down to the product options available in that size. Most Legacy fitments here are blackwall, while 205/60R16 also offers a wide whitewall presentation for a more distinctive look. If originality matters at a detailed level, it is worth checking Subaru-specific brochures, window-sticker records, or marque resources before treating any brand or sidewall treatment as the exact factory-delivered look.
Does correct tire fitment matter for a 2010 Subaru Legacy restoration?
Correct tire fitment matters on a 2010 Subaru Legacy restoration because the model used different tire sizes across its sub-models, and those sizes are tied to different wheel diameters. Using the right size helps maintain the intended visual balance of the car and keeps the wheel-and-tire package consistent with the trim being restored.
That is especially important on a modern collector car where a wheel swap can easily blur the original configuration. Matching the correct 16-inch, 17-inch, or 18-inch setup should come before choosing a tire series or sidewall style. Once the proper size is settled, the remaining decisions are about presentation and road use rather than basic fitment accuracy.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Subaru Legacy?
Yes, modifications can affect tire fitment on a 2010 Subaru Legacy even when the replacement tire matches one of the original sizes. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change how much space the tire has at the fender, strut, and steering components.
That is why a modified Legacy should be checked as it sits, not only by the original trim specification. Confirm the actual wheel diameter and width, compare the current tire size to the intended replacement, and inspect turning and suspension clearance before road use. This is particularly important on cars that have moved from 16-inch wheels to 17-inch or 18-inch setups over time.
What should I inspect before driving a 2010 Subaru Legacy on new tires?
Before driving a 2010 Subaru Legacy on new tires, inspect wheel diameter, wheel width, tire pressure, valve stems, and basic clearance at the fenders and suspension. It is also smart to look over alignment condition, tread seating, and any signs that the car has been altered from its original wheel and tire configuration.
A short initial drive should be followed by another visual check for rubbing, uneven wear, or pressure loss. On a Legacy with all-wheel-drive expectations and multiple original tire sizes across the range, consistency matters more than guesswork. Paying attention to the wheel-and-tire package as a system helps catch issues early and makes the transition to new tires much more predictable.
How often should tires on a 2010 Subaru Legacy be inspected?
Tires on a 2010 Subaru Legacy should be inspected regularly, not just when tread looks worn. A quick check of pressure, visible tread condition, cracking, cuts, bulges, and uneven wear is worthwhile before routine driving, and a more careful inspection makes sense before a longer trip or after the car has been sitting.
That routine becomes even more important on an older Legacy that may see limited use or seasonal storage. Tires can age even when mileage stays low, and a car with changed wheels or suspension deserves extra attention to clearance and wear patterns. Catching air loss, sidewall damage, or abnormal wear early helps keep the correct tire size working as intended.
