The 2011 Subaru Legacy sits in the modern all-wheel-drive sedan category where everyday usability, four-season confidence, and trim-specific personality all matter. In this generation, the Legacy ranged from practical 2.5i models to the stronger 3.6R cars and the 2.5GT with its sportier setup, so tire fitment is tied closely to the exact version in the driveway. This car uses radial tires throughout, but the correct size changes by sub-model across 16-, 17-, and 18-inch rims. Available choices also vary from blackwall performance-oriented lines to a 205/60R16 wide whitewall option. The key is matching the tire to the sub-model, wheel diameter, and the look or road feel you want.
Which Tire Size Is Right for The 2011 Subaru Legacy
The 2011 Subaru Legacy uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Fitment spans 16-, 17-, and 18-inch rims, so the first step is confirming both the trim and the wheels currently on the car. Once that is settled, the real choice becomes the type of radial tire you want within the correct size, including performance-focused blackwall options or, in one size, a more appearance-driven whitewall style.
225/45R18 is a metric radial size with a 225-millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. On the 2011 Subaru Legacy, this size is tied to the 2.5GT summer-tire application and points toward a more performance-oriented setup than the smaller Legacy tire sizes. Available choices in this size come from BFGoodrich and Nitto, all in blackwall form, with g-Force and NT555 G2 series options. It is the size to evaluate when the car already has the correct 18-inch wheel package and you want to stay aligned with that sport-focused fitment.
205/60R16 is a metric radial size that pairs a 205-millimeter section width with a 60-series profile on a 16-inch rim. For the 2011 Subaru Legacy, it serves the 2.5i and 2.5i Premium applications, making it one of the more straightforward fitments in the range. The available option in this size is an American Classic radial with a 1.50-inch whitewall and asymmetrical tread, so appearance plays a larger role here than outright performance variety. This size deserves a close look when maintaining the standard 16-inch wheel setup or pursuing a more distinctive visual presentation.
215/50R17 is a metric radial size with a 215-millimeter section width, a 50-series profile, and a 17-inch rim diameter. On the 2011 Subaru Legacy, this size applies to the 2.5i Limited, placing it between the base 16-inch fitment and the wider 225-section alternatives used elsewhere in the lineup. BFGoodrich offers several blackwall choices in this size, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. It is the right size to assess when the car is a 2.5i Limited and still carries the proper 17-inch wheels.
225/50R17 is a metric radial size that uses a 225-millimeter section width, a 50-series profile, and a 17-inch rim. For the 2011 Subaru Legacy, this size belongs to the 3.6R, 3.6R Limited, and 3.6R Premium models, so it is shared across the six-cylinder branch of the lineup. Available blackwall options include BFGoodrich g-Force series tires and the Nitto NT555 G2, giving this size a mix of recognizable performance-oriented choices. It makes sense when the Legacy is a 3.6R-based model and the goal is to preserve the correct 17-inch fitment rather than substitute another size.
Sub-model fitment on the 2011 Subaru Legacy is not one-size-fits-all, because tire size changes across the 2.5i, 2.5GT, and 3.6R branches. Checking the exact trim and wheel diameter matters before comparing products, since a Legacy on 16-inch wheels calls for a different tire than one equipped with 17- or 18-inch rims.

2011 Subaru Legacy 2.5GT (Summer Tires)
The 2011 Subaru Legacy 2.5GT with summer tires uses the 225/45R18 radial fitment, making it the largest wheel-and-tire package in this group. Tire selection here centers on staying with the proper 18-inch setup and choosing among blackwall performance-oriented radial lines.
The 2011 Subaru Legacy 2.5i uses the 205/60R16 radial size on a 16-inch rim, which separates it clearly from the 17- and 18-inch Legacy trims. The main decision is preserving that standard-size fitment while choosing a tire that suits the car's intended appearance and everyday use.
The 2011 Subaru Legacy 2.5i Limited uses 215/50R17 radial tires, giving it a distinct fitment from the 16-inch 2.5i models and the wider 225-section alternatives elsewhere. Tire selection should stay focused on the correct 17-inch wheel setup and the available blackwall performance-style options in this size.
The 2011 Subaru Legacy 2.5i Premium shares the 205/60R16 radial size with the 2.5i, so fitment remains straightforward within those two trims. That makes the real choice less about sizing and more about keeping the correct 16-inch setup while deciding how much appearance should factor into the tire selection.
The 2011 Subaru Legacy 3.6R uses the 225/50R17 radial fitment, which it shares with the other 3.6R sub-models. Choosing tires for this version comes down to confirming the 17-inch wheels and comparing the available blackwall radial lines in the correct size.
The 2011 Subaru Legacy 3.6R Limited also uses 225/50R17 radial tires, so its fitment is consistent with the rest of the 3.6R group. That shared size keeps selection simple once the trim is confirmed, leaving brand and tire series as the main comparison points.
The 2011 Subaru Legacy 3.6R Premium carries the same 225/50R17 radial size used across the 3.6R range. Buyers should verify the 17-inch wheel setup first, then compare the available blackwall tire series that suit the car's intended road use.
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.

Available 2011 Subaru Legacy tire choices vary by size, brand, and series, with BFGoodrich and Nitto covering several blackwall performance-oriented fitments and American Classic offering a wide whitewall option in 205/60R16. Comparing the product grid is mostly about matching the right size first, then weighing series character, sidewall style, and rim-width compatibility.
Tire questions for the 2011 Subaru Legacy usually come down to trim-specific sizing, wheel diameter, available radial choices, and how to compare blackwall performance tires with the lone whitewall option. The answers below focus on fitment first, then selection, maintenance, and real-world checks before driving.
Tire Size & Fitment
What tire size fits a 2011 Subaru Legacy?
The 2011 Subaru Legacy uses four tire sizes depending on sub-model: 205/60R16, 215/50R17, 225/50R17, and 225/45R18. The 2.5i and 2.5i Premium use 205/60R16, the 2.5i Limited uses 215/50R17, the 3.6R models use 225/50R17, and the 2.5GT summer-tire application uses 225/45R18.
Finding the right size starts with identifying the exact trim and confirming the wheel diameter on the car. A Legacy that has been fitted with different wheels over the years may no longer match its original sub-model pattern, so the safest approach is to verify both the trim badge and the current rim size before selecting a tire.
What size rim does a 2011 Subaru Legacy use?
A 2011 Subaru Legacy can use 16-inch, 17-inch, or 18-inch rims depending on the sub-model and tire package. The 205/60R16 fitment uses a 16-inch rim, both 215/50R17 and 225/50R17 use 17-inch rims, and the 225/45R18 summer-tire setup uses an 18-inch rim.
Wheel diameter is the first thing to confirm before comparing tires, because none of these sizes cross over to a different rim size. Looking at the sidewall on the current tire or measuring the wheel is especially helpful if the car has aftermarket wheels, a replacement wheel set, or a trim history that is unclear.
Why does the 2011 Subaru Legacy have more than one tire size?
The 2011 Subaru Legacy has more than one tire size because the lineup includes different sub-models with different wheel packages. The 2.5i models, 2.5i Limited, 3.6R models, and 2.5GT summer-tire application do not all share the same rim diameter or section width, so each uses its own radial tire size.
That means tire selection is tied to the exact version of the car rather than the Legacy name alone. Matching the correct size preserves the intended wheel relationship and avoids choosing a tire simply because it looks close, which is especially important when comparing 16-, 17-, and 18-inch Legacy configurations.
Choosing the Right Tire
What should I consider when choosing a 2011 Subaru Legacy tire?
Start with the correct size for the exact 2011 Subaru Legacy sub-model, then compare the tire's series, sidewall treatment, and rim-width compatibility within that size. The Legacy range includes blackwall performance-oriented choices in 215/50R17, 225/50R17, and 225/45R18, while 205/60R16 includes a wide whitewall radial option.
That makes the decision less about one universal Legacy tire and more about the role the car plays. A 2.5GT on 18-inch wheels calls for a very different tire conversation than a 2.5i on 16-inch rims, so choose around the car's actual wheel setup, appearance goals, and the kind of road use it sees.
What sidewall styles are available for 2011 Subaru Legacy tires?
Sidewall style depends on the tire size used on the 2011 Subaru Legacy. The 17-inch and 18-inch fitments offered here are blackwall radials, while the 205/60R16 size includes an American Classic radial with a 1.50-inch wide whitewall. That creates a clear visual split between sporty and more appearance-driven choices.
Sidewall treatment can change the character of the car even when the basic size remains correct. Buyers working with a 16-inch Legacy setup may want to decide whether the whitewall look suits the car's presentation, while 17- and 18-inch Legacy owners are choosing among blackwall options that keep a more modern tire appearance.
What brands offer tires for the 2011 Subaru Legacy?
Tires for the 2011 Subaru Legacy are available here from BFGoodrich, Nitto, and American Classic, depending on the size. BFGoodrich appears across several 17-inch and 18-inch fitments, Nitto is available in the 225/45R18 and 225/50R17 sizes, and American Classic covers the 205/60R16 application.
Brand comparison only matters after the correct tire size is confirmed, since not every brand appears in every Legacy fitment. Once the size is settled, it becomes easier to compare the available series, sidewall style, and rim-width suitability inside that one application instead of treating the entire Legacy lineup as a single tire category.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Subaru Legacy?
Yes, modifications can affect tire fitment on a 2011 Subaru Legacy even when the tire size matches a known Legacy application. Aftermarket wheels, changes in wheel width, suspension lowering, and body or alignment changes can all alter how a 205/60R16, 215/50R17, 225/50R17, or 225/45R18 tire sits in the car.
A modified Legacy should be checked for wheel diameter, width, and clearance at the fenders and steering components before new tires are installed. That is particularly important when the car no longer carries its original wheel package, because a size that suits one Legacy configuration may create issues on another with a different setup.
What should I inspect before driving a 2011 Subaru Legacy on new tires?
Before driving a 2011 Subaru Legacy on new tires, inspect the wheels for the correct diameter and condition, confirm inflation pressure, and make sure each tire matches the intended size for the car's trim. It also helps to check for uneven suspension wear, damaged valve stems, and any signs that prior tire clearance was marginal.
A short road test should follow installation so steering feel, vibration, and clearance can be evaluated at low speed first. Looking over tread and sidewalls after the first drive can reveal rubbing or setup issues early, especially if the Legacy has replacement wheels or has not been on fresh tires in some time.
How often should tires on a 2011 Subaru Legacy be inspected?
Tires on a 2011 Subaru Legacy should be inspected regularly for pressure, tread condition, cracking, cuts, bulges, and uneven wear. Even on a newer-style car like this, low-use examples can age their tires long before the tread is worn out, so visual checks matter as much as mileage in many cases.
A monthly inspection is a practical habit, with a closer look before longer drives or seasonal use changes. Any Legacy that sits for extended periods should also have its tires checked for flat spotting and slow air loss, since storage conditions and infrequent driving can quietly affect road readiness.
