The 1989 Subaru Justy came from an era when small, efficient hatchbacks were built around light weight, simple packaging, and practical city driving. Its compact footprint and economy-focused design make tire fitment especially important, because wheel size and overall proportions have a noticeable effect on how the car looks and drives. This Justy uses radial tires, but fitment is split between two sizes: 145R12 and 165/65R13. That means the first decision is confirming the exact sub-model and wheel diameter before looking at tire choices. For an owner trying to keep the car usable and visually appropriate, correct size selection comes before anything else.
Which Tire Size Is Right for The 1989 Subaru Justy
The 1989 Subaru Justy uses two primary tire sizes, and the correct one depends on the specific sub-model. Those sizes also use different rim diameters, so the first thing to confirm is whether the car has 12-inch or 13-inch wheels. Once that is settled, the decision becomes much more straightforward because both fitments are radial, with selection focused on matching the proper size and wheel setup.
145R12 is a Euro-metric radial size that uses a 145-millimeter nominal section width, radial construction, and a 12-inch rim diameter. In this format, the aspect ratio is not stated in the size itself and is commonly understood as a taller-profile metric radial style. On the 1989 Subaru Justy, this size is tied to the 12-inch wheel fitment and suits buyers who need to stay with the smaller original wheel diameter. Michelin offers this size in the Michelin MX series with a blackwall appearance, making it a focused choice for a clean, understated presentation.
165/65R13 is a metric radial size with a 165-millimeter section width, a 65-series aspect ratio, radial construction, and a 13-inch rim diameter. Compared with older numeric or unstated-aspect-ratio sizing, this format gives a more modern-looking size code that clearly identifies profile and wheel diameter. On the 1989 Subaru Justy, it belongs to sub-models equipped with 13-inch wheels, so wheel confirmation is essential before selecting it. This is the size to evaluate when the car is a GL or RS configuration using the larger factory wheel diameter.
Sub-model fitment matters on the 1989 Subaru Justy because tire size changes with the trim. The DL uses a different wheel and tire package than the GL and RS, so confirming the exact sub-model is the quickest way to avoid a size mismatch.

1989 Subaru Justy DL
The 1989 Subaru Justy DL uses the 145R12 radial size on a 12-inch wheel package. That makes tire selection more about staying with the correct smaller-diameter fitment and choosing a tire that preserves the car's compact proportions.
The 1989 Subaru Justy GL uses the 165/65R13 radial size, which differs from the DL fitment. Tire selection starts with keeping the 13-inch wheel diameter in mind and making sure the car has not been changed to a different wheel setup over time.
The 1989 Subaru Justy RS also uses the 165/65R13 radial size. For this sub-model, the main fitment task is confirming the existing 13-inch wheels and choosing a tire that matches the intended road use and overall appearance of the car.
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 1989 Subaru Justy Tires for Sale
Available product choice for the 1989 Subaru Justy is centered on 145R12, with a Michelin MX radial offered in a blackwall design. That gives buyers a clear period-friendly option to compare against the vehicle's wheel diameter and intended presentation.
These FAQs focus on the 1989 Subaru Justy's two tire sizes, the sub-model split between 12-inch and 13-inch wheels, radial fitment, product selection, and the basic checks worth making before putting a lightly used older compact back on the road.
Tire Size & Fitment
What tire size fits a 1989 Subaru Justy?
A 1989 Subaru Justy uses either 145R12 or 165/65R13, depending on the sub-model. The DL uses 145R12, while the GL and RS use 165/65R13. Both are radial tire fitments, but they are not the same size and they do not use the same rim diameter.
The practical step is to confirm the exact sub-model and then verify the wheel diameter currently on the car. Many older small cars have changed wheels over the years, so checking the sidewall size on the existing tires and measuring the wheel before ordering helps prevent choosing a 12-inch tire for a 13-inch setup or the other way around.
What size rim does a 1989 Subaru Justy use?
The 1989 Subaru Justy uses either a 12-inch or 13-inch rim, depending on the tire size and sub-model. The 145R12 fitment uses a 12-inch rim, and the 165/65R13 fitment uses a 13-inch rim. Rim diameter is tied directly to the tire size on this car.
That means wheel diameter must be confirmed before any tire choice is made. A tire marked 145R12 cannot be mounted on a 13-inch wheel, and a 165/65R13 cannot be used on a 12-inch wheel. On an older Justy, it is also smart to confirm that aftermarket wheels were not added at some point, especially if the car has changed hands several times.
Do all 1989 Subaru Justy sub-models use the same tire size?
No, the 1989 Subaru Justy does not use one tire size across all sub-models. The DL uses 145R12, while the GL and RS use 165/65R13. That difference also means the car may have either 12-inch or 13-inch wheels depending on the version.
For a buyer or owner, that makes sub-model identification more than a trim detail. It determines the tire size and the wheel diameter the car should have. If the badges are missing or the car has been modified, checking the current wheel diameter and tire sidewall marking is the safest way to confirm which fitment matches the vehicle.
Choosing the Right Tire
What should I consider when choosing a 145R12 tire for a 1989 Subaru Justy?
Start by confirming that the car is a 1989 Subaru Justy DL or otherwise equipped with 12-inch wheels, because 145R12 belongs to that smaller-wheel fitment. This size is a Euro-metric radial format, so the key factors are matching the tire size exactly, keeping the correct rim diameter, and choosing a tire style that suits the car's intended use.
Product choice in 145R12 is more focused than broad, so details such as sidewall appearance, tire series, and rim-width compatibility matter. A blackwall Michelin MX is available in this size, which gives the buyer a straightforward period-minded radial option. On a lightly used older compact, proper fit and wheel compatibility are more important than chasing a different size.
What sidewall styles are available for 1989 Subaru Justy tires?
The available 145R12 product for the 1989 Subaru Justy uses a blackwall sidewall style. That gives the car a simple, understated appearance that suits many late-1980s economy cars without adding a more decorative sidewall treatment such as a whitewall or raised white letter design.
Sidewall style affects appearance more than fitment, but it can still influence the look of a restored or preserved Justy. A blackwall presentation tends to keep attention on the compact proportions of the car rather than the tire itself. The more important selection point remains choosing the correct size for the sub-model and matching it to the wheel diameter already on the vehicle.
What brands offer tires for the 1989 Subaru Justy?
Michelin is represented in the available 145R12 fitment for the 1989 Subaru Justy through the Michelin MX series. That means buyers looking for the DL's 12-inch tire size have a recognizable radial option with a blackwall presentation and a traditional small-car look.
Brand matters, but it should come after size and wheel confirmation on this car. The Justy's split fitment makes it more important to match the DL, GL, or RS correctly than to start with a brand preference. Once the correct tire size is confirmed, comparing the available brand and tire series becomes much more useful and much less likely to lead to a mismatch.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Subaru Justy?
A period-style 1989 Subaru Justy should start with the correct original-size fitment for the sub-model: 145R12 for the DL or 165/65R13 for the GL and RS. Keeping the proper size and wheel diameter does more for the car's visual balance than moving to an unrelated substitute that changes sidewall shape or overall proportions.
For a restoration-oriented DL, a blackwall radial such as the available Michelin MX keeps the presentation simple and era-appropriate. Buyers aiming for exact historical accuracy should still compare their car against marque references, surviving examples, and original vehicle literature. On a car this small, even modest departures from the intended tire size can change its stance noticeably.
Does correct tire fitment matter for a 1989 Subaru Justy restoration?
Yes, correct tire fitment matters on a 1989 Subaru Justy restoration because the car's compact size makes wheel and tire proportions very visible. Using the right sub-model fitment helps preserve the intended look of the DL, GL, or RS and keeps the wheel diameter in line with the vehicle's original setup.
Fitment also affects how believable the finished restoration feels. A 12-inch DL setup looks different from a 13-inch GL or RS setup, so mixing them can alter the car's character even before it moves. For appearance-conscious owners, matching the proper size first and then choosing a suitable sidewall style is usually the soundest approach.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Subaru Justy?
Yes, modifications can affect tire fitment on a 1989 Subaru Justy. Aftermarket wheels, suspension changes, altered ride height, or body and brake changes can all influence whether the original 145R12 or 165/65R13 sizing still makes sense on the car. Even a small change can matter on a vehicle with limited wheelwell space.
The safest approach is to verify current wheel diameter, wheel width, and available clearance before selecting tires. Steering lock, fender clearance, and suspension travel all deserve a look, especially if the car sits lower or uses non-original wheels. On a compact hatchback like the Justy, small fitment differences are more noticeable than they would be on a larger vehicle.
What should I inspect before driving a 1989 Subaru Justy on new tires?
Before driving a 1989 Subaru Justy on new tires, inspect the wheels for damage or corrosion, confirm the tire size matches the sub-model, and make sure the tires seat properly on the rims. It is also wise to check valve stems, wheel fastener condition, and basic alignment if the old tires showed uneven wear.
A road-ready check should also include tire pressure, visible sidewall condition, tread seating after installation, and clearances at full steering lock. Since many older Justys see occasional use rather than daily service, it helps to inspect suspension bushings, shocks, and brakes at the same time. A fresh set of tires performs best when the rest of the rolling hardware is equally sound.
How should tires on a collector-era 1989 Subaru Justy be maintained?
Tires on a collector-era 1989 Subaru Justy should be maintained with regular pressure checks, visual inspections, and periodic examination for cracking, bulges, cuts, or uneven wear. Low-mileage cars can still develop tire problems from age, long storage, and repeated sitting, even when tread depth looks acceptable.
Storage conditions matter almost as much as driving miles. Keeping the Justy away from prolonged sunlight, moisture, and ozone sources helps preserve the tire casing and sidewall condition over time. It also pays to move the car occasionally or avoid leaving it parked on one spot for extended periods, especially if the vehicle is used seasonally rather than as a daily driver.
