The 1991 Subaru Legacy came to market as Subaru’s modern midsize sedan and wagon line, bringing all-weather confidence and a more refined road-car character to the brand’s early 1990s lineup. That matters when choosing tires today, because this model uses radial fitments only, but the exact size depends on the sub-model. Most 1991 Legacy trims use 14-inch sizes such as 185/70R14 or 175/70R14, while the Legacy Sport steps up to 195/60R15. Available choices range from blackwall touring and sport-oriented radials to whitewall and redline presentations, so the right selection depends on whether the goal is stock-style driving, period-inspired appearance, or confirming fitment on wheels that may have changed over time.
Which Tire Size Is Right for The 1991 Subaru Legacy
Three tire sizes apply to the 1991 Subaru Legacy, and the right one depends on the exact sub-model and wheel diameter. The first step is confirming whether the car uses a 14-inch or 15-inch rim, because both appear in this model range. Once that is settled, the choice becomes more about selecting the right radial tire style, brand, and sidewall treatment for the way the car is being restored, maintained, or driven.
185/70R14 is a modern metric radial size: 185 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. On the 1991 Subaru Legacy, this size suits several 14-inch-wheel trims and keeps the fitment in the original radial format used by the car. Available choices include blackwall and wide whitewall styles from brands such as BFGoodrich, Avon, Dunlop, Michelin, and Vredestein across series like Silvertown Radial, CR6ZZ, Sport Classic, XAS, and Sprint Classic. It is the size to evaluate when the car is one of the 14-inch Legacy models that did not use the narrower 175-section tire.
175/70R14 is also a modern metric radial size, with a 175-millimeter nominal section width, a 70-series profile, radial construction, and a 14-inch rim diameter. On the 1991 Subaru Legacy, this size is tied to a specific 14-inch-wheel configuration rather than the full model range, so it should not be assumed to match every trim. The available product in this size uses a narrow whitewall presentation, which gives this fitment a more appearance-driven replacement path than the broader assortments seen in some other Legacy sizes. It is worth choosing carefully when maintaining the exact wheel and sub-model setup already on the car.
195/60R15 follows the same modern metric radial format, but with a wider 195-millimeter section width, a lower 60-series profile, and a 15-inch rim diameter. This size belongs to the 1991 Subaru Legacy Sport, making wheel diameter confirmation especially important before selection. Product choices include blackwall, wide whitewall, raised white letter, and redline treatments, with BFGoodrich and Michelin offerings in series such as Silvertown Radial, Radial T/A, and Primacy 3. It is the right fitment to examine when the goal is matching the Sport model’s 15-inch setup while still choosing between traditional-looking and more performance-flavored radial presentations.
Tire fitment for the 1991 Subaru Legacy varies by sub-model, so identifying the exact trim is essential before choosing a replacement tire. Most covered versions use 14-inch radial sizes, while the Legacy Sport uses a different 15-inch fitment.

1991 Subaru Legacy L (AWD)
The 1991 Subaru Legacy L (AWD) uses a 14-inch radial tire setup distinct from the front-wheel-drive L. That makes trim confirmation important before replacement, especially if the car has changed hands or had wheels swapped at some point.
The 1991 Subaru Legacy L (FWD) uses a narrower 14-inch radial fitment than the all-wheel-drive L and several other Legacy trims. Tire selection here is less about broad style variety and more about staying with the proper size for the wheel and vehicle configuration.
The 1991 Subaru Legacy LS shares the same 14-inch radial fitment used by several other Legacy sub-models. That gives the buyer room to compare blackwall and whitewall presentations while still keeping the car in the correct basic size range.
The 1991 Subaru Legacy LSi uses the same 14-inch radial size as the LS and the all-wheel-drive L. For tire selection, that means the main choice is usually between touring-oriented blackwall options and a more restoration-minded sidewall appearance.
The 1991 Subaru Legacy Sport moves to a 15-inch radial fitment that differs from the rest of the covered Legacy range. Tire choice starts with confirming those 15-inch wheels, then deciding whether the car calls for blackwall, raised white letter, whitewall, or redline styling.
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.

Common 1991 Subaru Legacy tire questions usually come down to exact trim fitment, 14-inch versus 15-inch wheels, sidewall appearance, and how to choose among the radial tire options available for each size.
Tire Size & Fitment
What tire size fits a 1991 Subaru Legacy?
The 1991 Subaru Legacy uses three tire sizes depending on sub-model: 185/70R14, 175/70R14, and 195/60R15. All three are radial sizes, and they are not shared across the entire Legacy range for this model year.
The key step is matching the tire to the exact trim and wheel diameter already on the car. Most versions use a 14-inch fitment, while the Legacy Sport uses a 15-inch setup, so checking the sub-model and the wheel itself helps prevent choosing the wrong size.
What size rim does a 1991 Subaru Legacy use?
A 1991 Subaru Legacy uses either a 14-inch or 15-inch rim, depending on sub-model. The 185/70R14 and 175/70R14 sizes are built for 14-inch wheels, while 195/60R15 is built for a 15-inch wheel.
That distinction matters more than it might seem, because the Legacy range includes both rim diameters in the same year. Before replacing tires, verify the wheel diameter stamped on the wheel or confirm the existing tire size, especially if the car may have received replacement wheels over the years.
Why does the 1991 Subaru Legacy have more than one tire size?
The 1991 Subaru Legacy has more than one tire size because different sub-models used different wheel and tire combinations. The front-wheel-drive Legacy L uses 175/70R14, several other trims use 185/70R14, and the Legacy Sport uses 195/60R15.
That means tire selection starts with vehicle configuration, not just the model name on the decklid. A buyer should identify the exact trim and confirm whether the car still has its intended wheel diameter before comparing brands, sidewall styles, or tire series within the correct size.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Subaru Legacy?
Start with the correct tire size for the exact 1991 Subaru Legacy sub-model, then confirm the wheel diameter matches that size. After that, compare radial tire choices by sidewall appearance, brand, tire series, and any rim-width details that apply to the wheel already on the car.
A restoration-minded Legacy may call for a whitewall or redline presentation, while a more stock-driving or road-use-focused car may point toward a blackwall radial. The right choice depends on how the car is used today and whether originality of appearance matters more than simply replacing worn tires.
What sidewall styles are available for 1991 Subaru Legacy tires?
1991 Subaru Legacy tire choices include blackwall, narrow whitewall, wide whitewall, redline, and raised white letter sidewall styles, depending on the size. Those appearance differences are spread across the 14-inch and 15-inch fitments rather than being available in every size.
That means sidewall choice should come after confirming the proper tire size for the car. Once size is settled, the sidewall becomes a useful way to shape the car’s presentation, whether the goal is a clean original-era look, a sportier treatment, or a more customized period-style appearance.
What brands offer tires for the 1991 Subaru Legacy?
Tires for the 1991 Subaru Legacy are available from BFGoodrich, Avon, Dunlop, Michelin, Travelstar, and Vredestein, depending on the size. Brand availability changes with the fitment, so one Legacy trim may have several choices while another has a narrower selection.
That makes size confirmation important before comparing brand names too closely. After identifying the correct fitment, look at each tire’s sidewall style, series, and wheel-compatibility details to narrow the field, since the best match for one Legacy trim may not even exist in another trim’s tire size.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Subaru Legacy?
A period-style 1991 Subaru Legacy tire choice starts with the correct original-size radial fitment for the exact sub-model. From there, the visual direction can shift toward blackwall for a straightforward early-1990s look or toward whitewall, redline, or raised white letter options where those styles are offered.
Appearance should be balanced with wheel diameter, intended use, and how closely the car is being restored. For buyers pursuing exact historical presentation, it is wise to compare the car against period photos, sales literature, or marque-specific references before choosing a sidewall treatment simply because it is available.
How does tire construction affect the appearance of a restored 1991 Subaru Legacy?
On a 1991 Subaru Legacy, construction changes are not the main appearance question because the fitments here are radial throughout. The visual difference comes more from the size itself and from sidewall treatment, with blackwall, whitewall, redline, and raised white letter options creating very different impressions.
That gives a restorer some flexibility without moving away from the basic radial format the car used. Even so, the tire still needs to match the sub-model’s wheel diameter and intended size, since an attractive sidewall treatment cannot make an incorrect 14-inch or 15-inch fitment appropriate for the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Subaru Legacy?
Yes, modifications can affect tire fitment on a 1991 Subaru Legacy, even when the tire size itself appears close to stock. Aftermarket wheels, suspension changes, lowering, and body alterations can change the wheel width, offset, or available clearance around the tire.
A Legacy that has been modified should be checked at the wheel and on the car rather than judged by model year alone. Pay attention to rim diameter, wheel width, steering clearance, and fender room before installing a new set, especially when moving between 14-inch and 15-inch combinations.
What should I inspect before driving a 1991 Subaru Legacy on new tires?
Before driving a 1991 Subaru Legacy on new tires, inspect the wheels for damage, confirm the tires match the correct size for the sub-model, and check that inflation is set appropriately for the installed tire. It is also smart to look over valve stems and make sure each tire seats properly.
A short initial drive should include attention to vibration, rubbing, or any steering behavior that feels unusual. On an older Legacy, it also helps to inspect suspension and alignment condition, because worn components can affect how even a correctly sized new radial tire behaves on the road.
How should tires on a collector 1991 Subaru Legacy be maintained?
Tires on a collector 1991 Subaru Legacy should be maintained with regular pressure checks, periodic visual inspection, and attention to age as well as tread depth. Collector cars often spend long periods parked, so sidewall cracking, flat spotting, and slow air loss deserve just as much attention as visible wear.
Storage conditions matter, too. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, while occasional movement can reduce stress from sitting in one position. Before a longer drive, inspect tread and sidewalls carefully and confirm the tires still suit the car’s wheel setup.
