The 1990 Subaru Justy came from an era when small imported hatchbacks were valued for simplicity, efficiency, and easy city use rather than sheer size or power. Its compact footprint and light-duty character make tire selection more sensitive than on larger cars, especially when wheel size changes between trims. For this model year, the Justy uses radial tires in either 145R12 or 165/65R13 depending on sub-model. That means the key decision is not just tread style, but confirming whether the car is a DL or GL and whether it still carries its original 12-inch or 13-inch wheels. For owners keeping a stock, roadworthy Justy, fitment comes first.
Which Tire Size Is Right for The 1990 Subaru Justy
The 1990 Subaru Justy uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. DL models use a 12-inch wheel with 145R12 tires, while GL models use a 13-inch wheel with 165/65R13 tires. Before choosing a tire, the first step is confirming the exact sub-model and checking which wheels are actually on the car today.
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 it is commonly treated as an older Euro-metric radial convention. On the 1990 Subaru Justy, this size is tied to the smaller-wheel fitment and suits buyers trying to preserve the car's original-size footprint. Michelin is available in this size with the Michelin MX series and a blackwall presentation, giving the buyer a straightforward period-appropriate radial option.
165/65R13 is a metric radial size with a 165-millimeter section width, a 65-series profile, radial construction, and a 13-inch rim diameter. Compared with older numeric or unstated-aspect-ratio sizing, this format is more familiar to modern buyers because the width, profile, and rim diameter are all spelled out in the code. On the 1990 Subaru Justy, this size belongs to the larger-wheel trim configuration rather than every version of the car. It is the right size to evaluate only after confirming that the vehicle is the correct sub-model and still uses 13-inch wheels.
Sub-model fitment matters on the 1990 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 simplest way to narrow the correct tire before comparing product options.

1990 Subaru Justy DL
The 1990 Subaru Justy DL uses the 145R12 radial size on a 12-inch wheel setup. For this trim, tire selection centers on staying with the proper smaller-wheel fitment and choosing a suitable radial option that matches the car's intended road use and appearance.
The 1990 Subaru Justy GL uses the 165/65R13 radial size, which places it on a different wheel diameter than the DL. That makes wheel confirmation especially important before purchase, particularly on cars that may have had wheels changed 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.

Tire Size & Fitment
What tire size fits a 1990 Subaru Justy?
A 1990 Subaru Justy uses either 145R12 or 165/65R13, depending on the sub-model. The DL uses 145R12 radial tires, while the GL uses 165/65R13 radial tires. Both are primary fitments for this model year, but they are tied to different wheel diameters and should not be treated as interchangeable choices for every Justy.
The practical step is to confirm both the trim and the wheels currently on the car before choosing a tire. A DL and GL do not share the same rim diameter, and many older small cars have had wheel changes over the years. Checking the sidewall on the existing tire and measuring the wheel diameter helps avoid ordering the wrong size.
What size rim does a 1990 Subaru Justy use?
The 1990 Subaru Justy uses either a 12-inch or 13-inch rim, depending on sub-model. The 145R12 fitment uses a 12-inch rim, and the 165/65R13 fitment uses a 13-inch rim. Rim diameter is a primary fitment point on this car because the two tire sizes do not share the same wheel size.
Wheel diameter should be confirmed before anything else, especially on an older economy car that may have been modified or repaired with replacement wheels. The tire size molded into the sidewall is a useful reference, but the wheel itself should still be checked. Matching tire and wheel diameter is fundamental before considering width, appearance, or brand preference.
Do all 1990 Subaru Justy sub-models use the same tire size?
No. The 1990 Subaru Justy DL uses 145R12, while the 1990 Subaru Justy GL uses 165/65R13. Both are radial tire fitments, but they differ in both size format and rim diameter. That means tire selection changes with the specific sub-model rather than staying uniform across the full 1990 Justy range.
This matters because choosing by model name alone is not enough on a Justy with multiple trim-level fitments. Verifying the exact trim, current wheel diameter, and any past wheel changes helps narrow the correct choice quickly. Once the proper size is confirmed, the next decision becomes product style, construction details, and whether the tire suits the car's intended use.
Choosing the Right Tire
What should I consider when choosing a tire for a 1990 Subaru Justy?
Start with the correct tire size for the exact sub-model. A 1990 Subaru Justy DL uses 145R12, while a GL uses 165/65R13, so the right choice begins with wheel diameter and trim identification. Construction is straightforward because both primary fitments are radial, which keeps the decision focused on sizing, wheel compatibility, and the character of the available tire.
After size is confirmed, compare practical details such as rim-width compatibility, sidewall appearance, load capability where relevant, and whether the tire suits a stock road-use setup. On a light older hatchback, even small sizing changes can affect clearance and presentation. Keeping the tire matched to the car's actual wheel setup is usually more important than chasing a broader selection.
What sidewall styles are available for 1990 Subaru Justy tires?
The available 145R12 product for the 1990 Subaru Justy uses a blackwall sidewall style. Blackwall suits the Justy's simple late-1980s to early-1990s small-car character and keeps the look understated. Sidewall style may seem secondary to size, but on a compact car with small-diameter wheels, it has a noticeable effect on how original or updated the finished appearance feels.
Appearance should be considered only after the correct fitment is established. A blackwall radial is often the natural choice for owners keeping the car close to stock in both look and use. If the Justy has had wheel or tire changes in the past, confirm the actual size on the car first so sidewall preference does not lead to ordering a tire for the wrong diameter.
What brands offer tires for the 1990 Subaru Justy?
Michelin is available for the 1990 Subaru Justy in the 145R12 fitment through the Michelin MX series. That gives buyers of the smaller-wheel setup a recognized radial option in the correct size format. Brand choice matters, but on a vehicle like the Justy, proper size and wheel match remain the first priorities before brand preference enters the decision.
It helps to think of brand as one part of the package rather than the starting point. Once the tire size is confirmed, compare the available brand offering with the car's intended use, sidewall appearance, and wheel specifications. On an older subcompact, a correctly matched tire usually contributes more to a satisfying result than simply choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1990 Subaru Justy?
A period-style 1990 Subaru Justy should begin with the correct original-size fitment for the specific sub-model: 145R12 for the DL or 165/65R13 for the GL. Because both primary fitments are radial, the restoration-oriented decision is less about changing construction and more about preserving the proper wheel diameter, tire proportions, and overall visual balance of the car.
Owners aiming for an authentic presentation should avoid treating the two sizes as interchangeable just because both belong to the same model year. Small hatchbacks are especially sensitive to tire shape and wheel diameter in side view. When exact originality matters, compare the car against period photos, marque references, and any surviving wheel and tire markings before final selection.
Does correct tire fitment matter for a 1990 Subaru Justy restoration?
Yes, correct tire fitment matters on a 1990 Subaru Justy restoration because the tire size directly affects the car's stance, wheel-to-body proportion, and overall presentation. With one trim using 145R12 and another using 165/65R13, the difference is not cosmetic alone. The wrong diameter can make a restored Justy look noticeably off even before the car is driven.
Fitment accuracy also helps keep the restoration practical rather than purely visual. Matching the tire to the intended wheel diameter supports proper mounting and keeps clearance questions manageable. On a compact collector-era import, small changes stand out quickly, so confirming the correct sub-model and wheel setup is one of the simplest ways to keep the finished car consistent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1990 Subaru Justy?
Yes. Modifications can affect tire fitment on a 1990 Subaru Justy, especially because the car already has two factory size paths tied to different wheel diameters. If the Justy has aftermarket wheels, altered ride height, replacement struts, or non-stock wheel offset, the original DL or GL size may no longer reflect the exact setup now on the car.
The sensible check is to verify wheel diameter and width first, then inspect clearance at the fenders, suspension, and steering range. A small car leaves less room for error than a larger platform. Even when using one of the known Justy sizes, the current wheel and suspension combination should be reviewed before mounting new tires.
What should I inspect before driving a 1990 Subaru Justy on new tires?
Before driving a 1990 Subaru Justy on new tires, inspect the wheels for damage, confirm the tire size matches the rim diameter, and make sure each tire is properly seated and inflated. It also helps to check for suspension wear, loose steering components, and any signs that the old tires rubbed the body or inner wheelhouse.
A short road test should be paired with a visual recheck for air loss, unusual contact marks, or vibration. On a light older hatchback, worn shocks, bent wheels, or alignment issues can show up quickly after a tire change. Looking over the full wheel-and-tire system helps the new tires perform as intended and reduces surprises on regular road use.
How should tires on a collector-era 1990 Subaru Justy be maintained?
Tires on a collector-era 1990 Subaru Justy should be kept at appropriate pressure, inspected regularly for cracking, cuts, bulges, and uneven wear, and checked for air loss if the car sits for long periods. Low-use cars often age their tires before they wear them out, so condition matters just as much as tread depth on an older Justy.
Storage also affects long-term tire life. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment can help preserve the sidewalls. A Justy that sees occasional use still benefits from routine inspection before each drive, especially since small-diameter tires can make age-related deterioration easier to overlook until problems become obvious.
