1989 Subaru Tire Fitment Guide

1989 Subaru vehicles use eight sizes across six model lines: 155R13 for DL, 165R13 for DL and XT, 185/70R13 for GL, GL-10, RX, and XT, 175/70R13 for GL and GL-10, 145R12 for Justy, 165/65R13 for Justy, and 205/60R14 plus 195/60R14 for XT. Rim diameters span 12, 13, and 14 inches, so fitment starts with the exact model and wheel package rather than the year alone.

Several of the supported sizes include rim-width guidance. 155R13 suits 4.00 to 5.50-inch rims, 165R13 suits 4.50 to 6.00-inch rims, 185/70R13 suits roughly 4.5 to 6.5-inch rims depending on the product, 175/70R13 suits 4.5 to 6.0-inch rims, and 145R12 appears on a 4.5-inch rim. That makes wheel diameter the first checkpoint and rim width the second when narrowing the correct tire.

On a 1989 Subaru, 155R13 means a radial tire with a nominal section width of 155 millimeters that fits a 13-inch wheel. Because no aspect ratio is written in that older metric format, it is conventionally treated as an 80-series radial. Within the 1989 Subaru range, that size belongs to the DL rather than the broader GL-family, Justy, or XT low-profile fitments.

That code matters because a 155R13 is not interchangeable with later lower-profile metric sizes simply because the wheel diameter matches. The tire’s overall height and section width are part of the intended setup. If your DL already wears 13-inch wheels, confirming whether it takes 155R13 or 165R13 is the right next step before comparing brands.

No, 1989 Subaru models do not use one common size. The DL uses 155R13 or 165R13, the GL and GL-10 use 175/70R13 or 185/70R13, the RX uses 185/70R13, the Justy uses either 145R12 or 165/65R13, and the XT ranges from 165R13 and 185/70R13 up to 195/60R14 and 205/60R14.

That variation means year and make alone are not enough for a confident tire choice on a 1989 Subaru. A Justy and an XT can both be 1989 Subarus yet require completely different wheel diameters and profiles. Identifying the exact model, then checking the current wheel diameter, will prevent mixing compact-car and specialty-coupe fitments.

1989 Subaru tire choices are mostly blackwall, which is the sidewall style seen in 155R13, 165R13, 175/70R13, 145R12, and 195/60R14 products. The standout is 185/70R13, which is also available in redline and wide whitewall form in addition to blackwall. Those alternate sidewall treatments are concentrated in that one size because it serves several Subaru models and has the broadest product range.

For a late-1980s Subaru restored to a factory-looking street presentation, blackwall is generally the most era-appropriate visual direction. Redlines and wide whitewalls create a more stylized appearance than most buyers would associate with a stock 1989 Subaru passenger car. If originality matters, choose the correct size first and then keep the sidewall style aligned with the character of the model.

Michelin, Dunlop, BFGoodrich, and Avon all cover parts of the 1989 Subaru range. Michelin appears in 155R13, 165R13, 145R12, and 195/60R14; Dunlop appears in 155R13, 165R13, and 185/70R13; BFGoodrich appears in 185/70R13; and Avon appears in 175/70R13 and 185/70R13. Brand choice therefore depends heavily on the exact Subaru model and size rather than on the make alone.

That spread gives some 1989 Subaru owners more flexibility than others. The broadest choice is in 185/70R13, while narrower or less common fitments such as 145R12 and 195/60R14 have a more focused offering. Once the correct size is confirmed, brand comparison becomes much more useful because you are looking within the actual fitment your Subaru uses.

For 1989 Subaru sizes such as 155R13 and 165R13, Michelin XAS and Dunlop SP Sport Aquajet are both radial blackwall choices, but they do not carry identical details. In 155R13, the Michelin XAS is marked 155HR13 78H TL and the Dunlop is marked 155R13 78H; in 165R13, Michelin versions are marked 165HR13 82H TL while the Dunlop is marked 165R13 82H. Michelin also shows rim-width guidance of 4.00 to 5.50 inches in 155R13 and 4.50 to 6.00 inches in 165R13, while Dunlop carries load figures of 937 pounds in 155R13 and 1,047 pounds in 165R13.

Those distinctions matter when you are matching the tire to the wheel and to the way the car is equipped. A buyer with original-size 13-inch Subaru wheels may pay close attention to the published rim-width range, while another may focus on load information or sidewall markings. The practical approach is to compare the exact product details within your confirmed size instead of assuming two blackwall radials are identical.

Several 1989 Subaru sizes have clear rim-width guidance. 155R13 fits 4.00 to 5.50-inch rims, 165R13 fits 4.50 to 6.00-inch rims, 185/70R13 fits from about 4.5 to 6.5 inches depending on the product, 175/70R13 fits 4.5 to 6.0-inch rims, and 145R12 appears on a 4.5-inch rim. Those ranges apply to the specific tire size, not automatically to every wheel used on every 1989 Subaru.

That is especially important with a 1989 Subaru XT, which can move between 13-inch and 14-inch fitments, and with a Justy that may use either a 12-inch or 13-inch wheel package. Always match the tire’s approved rim-width range to the wheel actually on the car. If your wheel falls outside that range, move to the correct size rather than trying to force a fit.

Most of the 1989 Subaru products with clear tube information are marked TL, meaning tubeless. That includes Michelin examples in 155R13, 165R13, 145R12, and 195/60R14. In some sizes, though, tube status varies by product because not every tire includes an explicit TL or TT marking in the sidewall notation, so it is important to check the exact tire rather than assume the whole size is identical.

For a late-1980s Subaru on original production-style wheels, tubeless radial fitment is the normal expectation. Even so, a buyer should confirm the sidewall marking and inspect the wheel condition, valve stem area, and bead seat before installation. If your chosen product uses a different marking than another tire in the same size, follow the tire maker’s setup requirements for that exact tire.

A 1989 Subaru should be stored on clean, properly inflated tires in a cool, dry place away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing sources. Radial tires generally tolerate storage better than older bias-ply designs, but they still age from heat, UV exposure, and long static periods. Keeping the car on a clean surface rather than bare dirt or damp ground also helps protect the tires.

If the Subaru will sit for an extended period, move it periodically to change the contact patch or place it on stands in a way that does not stress the suspension. Check inflation before and after storage, and look for early sidewall weathering when the car comes back into use. Limited-use collector cars often age their tires out long before they wear them out.

On a 1989 Subaru, tire life is usually judged more by age than by mileage. A sound rule for collector and occasional-use cars is to begin evaluating tires closely once they are about five to seven years old and to treat around ten years as a point where replacement deserves serious consideration, even if the tread still looks good. The DOT date code on the tire is the key reference for age.

That matters because many older Subarus see light seasonal use, which can hide age-related hardening and cracking. A tire with plenty of tread may still be past its best service life if it has been exposed to heat cycles, long storage, or years of underuse. Date codes, physical condition, and how the car is driven should all carry more weight than tread depth alone.

Tires on a 1989 Subaru should be inspected before every drive and again before any longer trip. Look for sidewall cracking, cuts, punctures, bulges, uneven tread wear, and any sign that the tire is losing pressure. Valve stems deserve the same attention, especially on an older car that may still wear aging hardware even when the tires themselves are newer.

A short pre-drive walkaround catches many of the problems that strand collector cars or make them unpleasant to drive. Add a more thorough inspection at seasonal service intervals, including tread-depth checks and wheel-condition review. If the Subaru has been parked for weeks or months, give the tires extra attention before returning the car to regular road use.

Many 1989 Subaru tire choices are entirely suitable for normal highway use when they are the correct size, in good condition, and properly inflated. The available speed ratings include S to 112 mph on 145R12, H to 130 mph on several 13-inch sizes, and V to 149 mph on some 185/70R13 and 195/60R14 products. Those limits are well above ordinary U.S. highway speeds, provided the tires are fresh and the rest of the car is mechanically sound.

For a 1989 Subaru, overall road safety often depends as much on suspension condition, brakes, alignment, and wheel integrity as on the speed symbol molded into the tire. A Justy, DL, and XT also place different demands on their tires because they use different sizes and profiles. Match the tire to the exact model and treat age and condition as seriously as the rating itself.

Inflation pressure on a 1989 Subaru should follow the vehicle manufacturer’s recommendation for the model and size, then be checked against the individual tire’s own maximum-load and pressure markings where available. Some 185/70R13 products carry a load figure of 1,135 pounds at 35 psi, while Dunlop examples show 1,047 pounds in 165R13 and 185/70R13 and 937 pounds in 155R13. Those numbers are tire ratings, not universal vehicle settings.

The safest approach is to use the Subaru placard or owner’s manual as the starting pressure for the exact model, then make sure the chosen tire is appropriate for that use. Do not transfer one pressure figure from a 13-inch DL tire to a 14-inch XT tire or from a Justy to a GL. Correct pressure depends on both the vehicle and the exact tire fitted.

Before a longer drive in a 1989 Subaru, inspect each tire for cracking, cuts, bulges, punctures, irregular wear, and correct cold inflation pressure. Check the spare as well, since many older cars still carry an original or very old backup tire that is no longer serviceable. On sizes with explicit tubeless marking, confirm the valve stems and wheel sealing surfaces are in good condition.

Tires are only one part of the pre-trip routine on an older Subaru. A sensible longer-drive check also includes brakes, wheel bearings, fluids, belts, cooling system condition, and suspension health. If anything about the tires feels uncertain during the inspection, resolve that first, because even a mechanically healthy 1989 Subaru depends on sound tires to be enjoyable and predictable on the road.
