The 2007 Subaru Legacy sits in the era when Subaru blended all-weather practicality with a sharper, more performance-oriented midsize sedan character. Depending on trim, this Legacy uses three modern radial tire sizes: 205/50R17, 215/45R17, and 215/45R18, so the first step is matching the exact sub-model and wheel diameter. From there, the choice is less about old bias-ply versus radial questions and more about selecting the right modern tire series, sidewall style, and wheel-width compatibility. That matters whether the goal is everyday road use, preserving the car's intended stance, or maintaining proper fitment on an unmodified or updated Legacy.
Which Tire Size Is Right for The 2007 Subaru Legacy
Three tire sizes apply to the 2007 Subaru Legacy, and the correct one depends on the specific sub-model and whether the car has 17-inch or 18-inch wheels. The 2.5i models use 205/50R17, the GT Limited uses 215/45R17, and the GT spec.B uses 215/45R18. Before comparing tire options, confirm the exact trim and actual wheel diameter on the car, especially if wheels have ever been changed.
Fit(s): 2.5i, 2.5i Limited, and 2.5i Special Edition
Construction: Radial|Rim: 17 in
205/50R17 is a metric radial size in which 205 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2007 Subaru Legacy, this size belongs to the 17-inch-wheel 2.5i family and keeps the sizing conversation centered on modern road manners and wheel compatibility. Available choices include BFGoodrich, American Classic, and Vredestein options, with both blackwall and wide whitewall presentations. It is a useful size to evaluate when the car is a 2.5i-based model and the goal is to balance fitment, appearance, and intended driving use.
215/45R17 is a metric radial size with a 215-millimeter nominal section width, a 45-series profile, radial construction, and a 17-inch rim diameter. On the 2007 Subaru Legacy, this size is tied to the GT Limited and reflects a lower-profile 17-inch fitment than the 2.5i models use. BFGoodrich offers this size across several g-Force series, all in blackwall form, giving buyers a focused choice within one brand family rather than a broad appearance range. This is the size to examine when the car is a GT Limited and the wheel setup remains true to that trim's 17-inch fitment.
215/45R18 is a metric radial size that uses the same 215-millimeter nominal width and 45-series profile as the 17-inch version, but it is built for an 18-inch wheel. On the 2007 Subaru Legacy, this size is associated with the GT spec.B, making wheel diameter the key fitment checkpoint before anything else. Available products center on BFGoodrich blackwall radial offerings in distinct g-Force series, so the decision is more about tire character and wheel-width compatibility than sidewall styling. This size belongs in the conversation when the car retains its 18-inch spec.B wheel fitment and stance.
Tire fitment changes across the 2007 Subaru Legacy range, so identifying the exact sub-model matters before selecting a tire. Most trims stay on 17-inch wheels, but one performance-oriented variant moves to an 18-inch fitment, which changes both size and wheel requirements.

2007 Subaru Legacy 2.5i
The 2007 Subaru Legacy 2.5i uses a 17-inch radial fitment centered on 205/50R17. Tire selection here comes down to choosing among available brands, series, and sidewall styles while keeping the wheel diameter and overall setup aligned with the car.
The 2007 Subaru Legacy 2.5i Limited shares the same 205/50R17 radial tire sizing as the other 2.5i-based trims. That makes tire choice fairly straightforward, with attention focused on appearance, tire series, and making sure the wheel on the car is still the intended 17-inch fitment.
The 2007 Subaru Legacy 2.5i Special Edition also uses 205/50R17 radial tires on a 17-inch wheel. Buyers can focus on product character and sidewall presentation rather than sorting through multiple primary sizes, provided the car has not been altered with a different wheel package.
The 2007 Subaru Legacy GT Limited uses a 215/45R17 radial tire, which differs from the 205-width fitment used on the 2.5i models. That means tire selection should start with confirming the GT Limited setup, then comparing the available blackwall g-Force series within the correct 17-inch size.
The 2007 Subaru Legacy GT spec.B moves to a 215/45R18 radial tire, making it the trim where wheel diameter becomes especially important. Tire choice should begin with confirming the 18-inch spec.B wheel fitment, then narrowing the decision to the available blackwall radial series in that size.
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.

Tire Size & Fitment
What tire size fits a 2007 Subaru Legacy?
The 2007 Subaru Legacy does not use one universal tire size across every trim. The 2.5i, 2.5i Limited, and 2.5i Special Edition use 205/50R17, the GT Limited uses 215/45R17, and the GT spec.B uses 215/45R18. All of these are radial fitments.
The practical decision starts with identifying the exact sub-model and confirming the wheel diameter actually on the car. A Legacy that has been fitted with aftermarket wheels or a different factory wheel package may no longer match its original trim-based tire size, so checking the current setup before ordering is important.
What size rim does a 2007 Subaru Legacy use?
A 2007 Subaru Legacy uses either a 17-inch or 18-inch rim, depending on sub-model. The 2.5i family and GT Limited are tied to 17-inch tire sizes, while the GT spec.B uses an 18-inch tire size. That wheel diameter difference is central to picking the correct tire.
Wheel diameter should be confirmed before comparing tread designs or tire series. A 17-inch tire cannot be mounted on an 18-inch wheel, and an 18-inch tire cannot be mounted on a 17-inch wheel, so the wheel itself needs to be verified first, especially on cars that may have had wheel swaps over time.
Do all 2007 Subaru Legacy sub-models use the same tire size?
No. The 2007 Subaru Legacy uses three different tire sizes across its sub-model range. The 2.5i-based trims share 205/50R17, the GT Limited uses 215/45R17, and the GT spec.B uses 215/45R18, so trim level directly affects tire selection.
That variation means a buyer should not choose tires by model name alone. The sub-model badge, existing wheel diameter, and current tire markings all deserve a quick check first, since a Legacy with changed wheels or a replacement wheel set may not still be running the size associated with its original trim.
Choosing the Right Tire
What should I consider when choosing a 2007 Subaru Legacy tire?
Start with the correct trim-based size, because the 2007 Subaru Legacy uses 205/50R17, 215/45R17, or 215/45R18 depending on configuration. From there, compare tire series, brand, sidewall style, rim-width compatibility, and any stated load figures that matter for the way the car is driven.
A 2.5i owner may have broader appearance choice in 205/50R17, while GT models are more focused on blackwall performance-style selections. It also helps to think about how the car is used: regular street driving, seasonal use, or a preserved enthusiast car can each point you toward a different balance of styling and specification.
What sidewall styles are available for 2007 Subaru Legacy tires?
Most available 2007 Subaru Legacy tire options are blackwall radials, especially in the 215/45R17 and 215/45R18 sizes. In 205/50R17, there is also a wide whitewall American Classic Radial, which creates a very different visual effect from the blackwall performance-oriented choices.
That means sidewall style is a real consideration mainly for the 2.5i-based 205/50R17 fitment. A blackwall keeps the presentation more contemporary and understated, while a wide whitewall gives the car a more custom or specialty appearance, so the right choice depends on how closely the tire's look should match the owner's vision for the car.
What brands offer tires for the 2007 Subaru Legacy?
Available tires for the 2007 Subaru Legacy include BFGoodrich across all three fitment sizes, along with Vredestein and American Classic in 205/50R17. The BFGoodrich range includes several g-Force series, while Vredestein Sprint Plus and American Classic Radial add different character within that 17-inch size.
Brand choice should still come after size confirmation, since not every brand appears in every Legacy fitment. Once the correct size is settled, compare the available series within that size for sidewall presentation, rim-width range, and any load or weight details that matter to the car's intended use and wheel setup.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Subaru Legacy?
A period-style 2007 Subaru Legacy tire choice starts with preserving the correct trim-based size and wheel diameter. For most owners, that means selecting a modern blackwall radial in the proper 17-inch or 18-inch size, since those fitments suit the Legacy's contemporary midsize sport-sedan era.
Appearance goals then narrow the field. A 205/50R17 Legacy has the broadest visual range because it includes both blackwall and wide whitewall options, while GT fitments stay focused on blackwall performance-style tires. For a restoration-minded presentation, the safest approach is matching the proper size first and keeping the wheel setup consistent.
Does correct tire fitment matter for a 2007 Subaru Legacy restoration?
Yes. Correct tire fitment matters because the 2007 Subaru Legacy used different sizes across its trim range, and those differences affect both appearance and stance. A 2.5i on 205/50R17 presents differently from a GT Limited on 215/45R17 or a GT spec.B on 215/45R18.
Using the wrong size can change the visual balance of the car and complicate wheel selection. Owners aiming for a restoration-oriented result should verify the sub-model first, then confirm that the wheel diameter on the vehicle still matches that trim. That keeps the tire decision grounded in fitment rather than guesswork or broad model-year assumptions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Subaru Legacy?
Yes. Wheel changes, suspension lowering, altered offsets, or body modifications can all affect tire fitment on a 2007 Subaru Legacy. That matters even more here because the car already uses multiple factory tire sizes, so an altered setup may differ from what the original trim would have used.
A Legacy with aftermarket wheels should be checked for actual wheel diameter and width before new tires are chosen. Clearance at the fender, strut, and steering range also deserves attention, especially when moving between factory-style 17-inch and 18-inch combinations or when the car no longer sits at stock ride height.
What should I inspect before driving a 2007 Subaru Legacy on new tires?
Before driving a 2007 Subaru Legacy on new tires, inspect the wheels for the correct diameter and any visible damage, then confirm the tires are the proper size for the trim and wheel setup. It is also wise to check inflation, tread seating, and general clearance around the fenders and suspension.
A short first drive should include attention to rubbing, vibration, or unusual steering feel. Since Legacy fitment varies by sub-model, this first check is especially important on a car with replacement wheels, suspension changes, or an uncertain service history, where the current hardware may not match the original factory-style setup.
How should 2007 Subaru Legacy tires be maintained?
2007 Subaru Legacy tires should be maintained with regular pressure checks, visual inspections for cuts, bulges, and cracking, and periodic review of tread condition. Because these are modern radial fitments, consistent pressure and condition monitoring play a major role in preserving predictable road behavior and tire life.
Cars that see occasional use deserve extra attention, since low annual mileage can hide age-related deterioration. Owners should inspect for air loss, uneven wear, and any signs that wheel alignment or suspension condition may be affecting the tires. Keeping the car stored away from prolonged heat, sunlight, and ozone sources also helps protect the tires over time.
