The 1991 Subaru Justy came from an era when small, efficient hatchbacks were built around light weight, compact dimensions, and practical city use. Its simple footprint and economy-minded design make tire selection especially important, because the wheel and tire package has a noticeable effect on stance, clearance, and everyday drivability. On this exact model, fitment depends on sub-model: the DL uses a 145R12 radial, while the GL uses a 165/65R13 radial. That means the decision starts with identifying the correct trim and wheel diameter, then narrowing the choice by tire style and intended use. For a stock Justy, staying close to the proper size keeps the car looking right and helps avoid needless fitment surprises.
Which Tire Size Is Right for The 1991 Subaru Justy
The 1991 Subaru Justy uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. The DL uses a 12-inch setup, while the GL uses a 13-inch setup, so confirming the exact trim and measuring the wheels already on the car should come first. Once that is settled, the next step is choosing the right radial tire within the proper size and overall presentation for the car.
145R12 is a Euro-metric radial size in which 145 is the nominal section width in millimeters, R identifies radial construction, and 12 is the rim diameter in inches. This format typically represents a tall, narrow small-car tire, which suits the 1991 Subaru Justy DL's compact, lightweight character. In this size, the available product uses a blackwall sidewall and belongs to the Michelin MX series. It is the size to evaluate when the car retains its 12-inch wheel setup and you want fitment that stays aligned with the DL's original wheel diameter.
165/65R13 is a metric radial size in which 165 is the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 13 is the rim diameter in inches. On the 1991 Subaru Justy, this size applies to the GL and uses a different wheel diameter than the DL. The lower-profile metric format makes wheel confirmation especially important before choosing a tire. This is the size to focus on when the car has its correct 13-inch GL wheel package and you want to avoid mixing trim-specific fitment.
Sub-model fitment matters on the 1991 Subaru Justy because the covered trims do not share the same tire size or wheel diameter. Checking whether the car is a DL or GL is the first step, since that determines which radial size belongs on the vehicle.

1991 Subaru Justy DL
The 1991 Subaru Justy DL uses a 145R12 radial on a 12-inch wheel setup, giving it a distinct fitment path from the GL. Tire selection here centers on keeping the correct small-diameter wheel package in place and choosing a radial that suits a stock, trim-specific presentation.
The 1991 Subaru Justy GL uses a 165/65R13 radial, so it requires a different tire and wheel diameter than the DL. That makes wheel verification essential before purchase, especially on cars that may have had wheels swapped over time.
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 1991 Subaru Justy Tires for Sale
Available products for the 1991 Subaru Justy currently center on the 145R12 size, with a Michelin MX radial in a blackwall sidewall style. For DL owners, the main comparison points are correct 12-inch fitment, radial construction, and the traditional look of a narrow small-car tire.
These FAQs focus on the exact tire sizes used on the 1991 Subaru Justy, how DL and GL fitment differs, what the size markings mean, and what to inspect before putting a stock or lightly changed Justy back on the road.
Tire Size & Fitment
What tire size fits a 1991 Subaru Justy?
A 1991 Subaru Justy uses one of two radial tire sizes, depending on sub-model. The DL uses 145R12, while the GL uses 165/65R13. Those are not interchangeable descriptions of the same fitment, because they also correspond to different wheel diameters.
The practical first step is identifying whether the car is a DL or GL and confirming the wheel diameter already on the vehicle. On older compact cars, previous owners sometimes change wheels, so checking the sidewall marking and measuring the rim helps prevent ordering the wrong size for the car's current setup.
What size rim does a 1991 Subaru Justy use?
The 1991 Subaru Justy uses either a 12-inch or 13-inch rim, depending on sub-model. A Justy DL uses the 145R12 size on a 12-inch rim, while a Justy GL uses the 165/65R13 size on a 13-inch rim.
Rim diameter is the most important number to confirm before choosing between these two sizes, because a 12-inch tire cannot be mounted on a 13-inch wheel and vice versa. Wheel swaps are common on older economy cars, so it is smart to verify the actual wheel size on the car rather than assuming the trim has remained unchanged.
Why does the 1991 Subaru Justy have more than one tire size?
The 1991 Subaru Justy has more than one tire size because the DL and GL use different wheel-and-tire packages. The DL uses 145R12, while the GL uses 165/65R13, so the size difference follows the sub-model rather than representing two interchangeable choices for the same configuration.
That means tire selection starts with trim identification and wheel confirmation, not with preference alone. If the car still has its original-style setup, the correct size is usually straightforward. If the Justy has aftermarket wheels or a prior owner changed the wheel package, the actual rim diameter and available clearance should be checked before settling on a tire.
Choosing the Right Tire
What should I consider when choosing a 145R12 tire for a 1991 Subaru Justy?
For a 1991 Subaru Justy DL, the starting point is keeping the correct 145R12 radial size on the proper 12-inch wheel. In this size, the available option is a Michelin MX blackwall radial, so the main considerations are correct fitment, radial construction, and whether that traditional narrow-tire appearance suits the car's condition and intended use.
It also helps to check the wheel itself before ordering. The available 145R12 product uses a 4.5-inch rim width, so matching the tire to the actual wheel on the car matters. Tire age, suspension wear, and any previous wheel changes can all affect how well the finished setup works on a light, compact Justy.
What sidewall styles are available for 1991 Subaru Justy tires?
For the currently available 145R12 fitment used on the 1991 Subaru Justy DL, the sidewall style available is blackwall. That gives the car a clean, understated appearance that suits many preserved and regularly driven small imports from the early 1990s.
Sidewall style is partly an appearance decision, but it should come after the correct size and wheel diameter are confirmed. On a Justy, the proportions of the tire are very visible because the car is so compact, so staying with the proper size matters more than chasing a different visual effect that could alter fitment.
What tire series are available for the 1991 Subaru Justy?
The available product coverage for the 1991 Subaru Justy currently includes the Michelin MX series in 145R12. That series is offered as a radial blackwall tire, giving DL owners a recognizable small-car radial option in the correct 12-inch size.
Series differences matter because they often shape the tire's appearance and overall character, even when the size stays the same. On a trim-specific car like the Justy, choosing the proper size and wheel diameter remains the first priority, then the tire series becomes part of the decision about how stock, tidy, or road-use-oriented the finished setup should feel.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Subaru Justy?
A period-style 1991 Subaru Justy should start with the correct trim-specific size and wheel diameter. That means 145R12 for a DL and 165/65R13 for a GL. Keeping the proper narrow radial proportions does more for the car's overall appearance than moving to a different size simply for convenience.
For a DL, the available Michelin MX blackwall maintains a restrained, era-appropriate small-car look. On any restoration-minded Justy, verify the actual wheels on the car before choosing tires, since older economy cars are often altered over time. Correct fitment helps preserve the visual balance that makes these lightweight hatchbacks look right.
Does correct tire fitment matter for a 1991 Subaru Justy restoration?
Correct tire fitment matters on a 1991 Subaru Justy restoration because the car's small dimensions make the wheel-and-tire package especially noticeable. Using the proper DL or GL size helps preserve the intended stance, keeps proportions in check, and avoids the mismatched look that oversized or incorrect-diameter tires can create.
Restoration-minded owners should begin with the right trim, the right rim diameter, and a tire whose overall presentation suits the car's era. Exact originality claims should be checked against vehicle-specific literature or marque references, but even without that level of research, staying with the proper fitment is the strongest starting point for a clean, convincing result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Subaru Justy?
Yes, modifications can affect tire fitment on a 1991 Subaru Justy, especially because the car uses small wheel diameters and trim-specific tire sizes. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the clearance picture enough that the original DL or GL fitment may no longer be the only factor.
A changed Justy should be checked for actual wheel diameter, wheel width, steering clearance, and space at the fender and suspension before choosing tires. Even modest wheel changes can matter on a compact hatchback, so it is worth measuring what is on the car now rather than assuming it still follows factory-style dimensions.
What should I inspect before driving a 1991 Subaru Justy on new tires?
Before driving a 1991 Subaru Justy on new tires, inspect the wheels for damage, verify that the wheel diameter matches the intended tire size, and check that the old tires did not hide suspension or alignment problems. It is also wise to look at valve stems, wheel hardware, and overall tread-to-body clearance once the new tires are mounted.
A short test drive should include listening for rubbing during turns and checking that the car tracks straight without vibration. Older lightweight cars can be sensitive to uneven wear, weak struts, or worn steering parts, so the tire installation is a good time to correct those issues before relying on the car for regular road use.
How should tires on a collector 1991 Subaru Justy be maintained?
Tires on a collector 1991 Subaru Justy should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and irregular wear, and checked for slow air loss between drives. Because cars like the Justy are often driven infrequently, visual condition and age-related deterioration can become as important as tread depth.
Storage habits also matter. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition during long idle periods. Moving the car occasionally and checking pressures before each outing can help avoid flat-spotting concerns and reduce the chance of discovering a problem only after the drive has started.
