The 1981 Subaru DL comes from the period when Subaru’s compact cars were earning a reputation for practical packaging, light weight, and everyday usability. For owners keeping one on the road today, tire choice is less about sorting through multiple factory sizes and more about preserving the car’s balanced, small-car character. This model uses a 155R13 radial tire on a 13-inch rim, giving the page a straightforward fitment starting point. Available choices stay within that traditional Euro-metric radial format and focus on differences in brand and tire series. The real decision is choosing a tire that suits restoration-minded appearance, road use, and the wheel setup actually on the car.
Which Tire Size Is Right for The 1981 Subaru DL
The 1981 Subaru DL uses one primary tire size: 155R13. That means the main fitment question is straightforward, since the tire is a radial design for a 13-inch rim and the covered DL Base sub-model uses the same size. From there, the decision shifts to choosing the right tire within that size, comparing brand, tire series, and wheel-width compatibility for the way the car will be driven and presented.
A 155R13 size uses a 155-millimeter nominal section width, radial construction, and a 13-inch rim diameter. In this format, the aspect ratio is not stated in the size itself, but it is commonly treated as an 80-series style radial, which suits the compact proportions of a 1981 Subaru DL. Available choices include Michelin and Dunlop blackwall tires in distinct series such as Michelin XAS-FF and SP Sport Aquajet. This size is the right starting point for keeping the car in its intended wheel diameter while comparing period-appropriate radial options.
Tire fitment is straightforward across the covered 1981 Subaru DL sub-models. The DL Base uses the same primary size, so the focus is less on trim differences and more on selecting the right radial tire within that shared fitment.

1981 Subaru DL Base
The 1981 Subaru DL Base uses the same 155R13 radial fitment as the core model. That keeps tire selection simple and lets the decision center on brand, tire series, and confirming that the wheel width and overall setup on the car still match the original-style 13-inch fitment.
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 questions for the 1981 Subaru DL usually come down to the 155R13 tire size, 13-inch rim fitment, brand and series choices, and the basic checks worth making before putting a lightly used vintage compact back on the road.
Tire Size & Fitment
What tire size fits a 1981 Subaru DL?
The 1981 Subaru DL uses a 155R13 radial tire. That is the primary fitment for this model, and the covered DL Base sub-model uses the same size, so there is no split fitment to sort through at this level.
A correct size match is only the first step on an older car. It still helps to confirm that the car retains 13-inch wheels, that wheel width falls within the tire’s requirements, and that no aftermarket suspension or wheel changes have altered clearance compared with the original-style setup.
What size rim does a 1981 Subaru DL use?
The primary tire fitment for a 1981 Subaru DL is built around a 13-inch rim. The 155R13 tire size itself confirms that rim diameter, and the available radial products for this application are also built for 13-inch wheels.
Rim diameter should be confirmed before ordering tires, especially on a vintage compact that may have been changed over the years. A 13-inch wheel is essential for this fitment, and wheel width matters too, since at least one available 155R13 tire is intended for a 4.00- to 5.50-inch rim width range.
Does the 1981 Subaru DL Base use the same tire size?
Yes. The 1981 Subaru DL Base uses the same 155R13 radial tire size as the core 1981 Subaru DL fitment. That makes sizing straightforward and keeps the focus on choosing among the available tires within that single size.
Shared sizing does not eliminate the need to inspect the actual car. A DL Base with replacement wheels, suspension work, or long-stored original wheels may still need wheel-width and condition checks before mounting new tires, particularly if the goal is to keep the car’s road manners and appearance close to its period feel.
Choosing the Right Tire
What should I consider when choosing a 155R13 tire for a 1981 Subaru DL?
Start with the correct 155R13 size and radial construction, then compare the available tires by brand, tire series, and wheel-width compatibility where stated. For this Subaru DL, the main choices stay within a traditional blackwall, small-car radial presentation rather than moving across several different fitment sizes.
The right choice depends on how the car will be used and how original-looking it needs to remain. A restoration-minded driver may lean toward a period-style tread and sidewall presentation, while a regular road-use owner may focus more on matching the tire to the wheel dimensions and the general condition of the suspension and steering.
What brands offer tires for the 1981 Subaru DL?
Michelin and Dunlop both offer tires in the 155R13 fitment used by the 1981 Subaru DL. That gives buyers a useful comparison between established vintage-oriented radial options while staying within the correct 13-inch sizing format for the car.
Brand should be considered alongside the actual tire series and specifications rather than by name alone. Looking at details such as stated rim-width range, load information where available, and the overall presentation of the tire helps narrow the choice to one that suits the Subaru’s wheels, intended use, and restoration goals.
What tire series are available for the 1981 Subaru DL?
Two distinct tire series are available in this fitment: Michelin XAS-FF and Dunlop SP Sport Aquajet. Both are radial blackwall options in the 155R13 size range used on the 1981 Subaru DL, but each has its own period character and specification profile.
Comparing series is helpful when the size itself is fixed and the choice comes down to overall presentation and compatibility. Looking beyond the size code to details like wheel-width suitability, tire weight where stated, and whether the car is being preserved as a period-style driver or a more display-oriented restoration makes the comparison more meaningful.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Subaru DL?
A period-style 1981 Subaru DL starts with the correct 155R13 radial format on a 13-inch rim. Since the available options remain in blackwall radial form, the decision is less about dramatic appearance changes and more about selecting the tire series and brand that best suit the car’s original small-car character.
For a restoration-minded result, keeping the proper size and overall visual proportion matters more than chasing novelty. Exact originality questions, especially for marque-specific presentation details, are best checked against period Subaru literature, club guidance, or surviving reference cars before settling on one tire series over another.
Does correct tire fitment matter for a 1981 Subaru DL restoration?
Yes. Correct tire fitment has a strong effect on how a 1981 Subaru DL looks, sits, and drives. Using the proper 155R13 radial size helps preserve the compact stance and wheel-to-tire proportions that suit the car far better than an arbitrary modern substitute.
Restoration quality is not only about appearance from a few feet away. Wheel diameter, tire section width, and sidewall profile all influence clearance and the overall impression of the car, so confirming the wheels and measuring the setup on the car is worthwhile before mounting tires intended to keep a period-style presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Subaru DL?
Yes. A 1981 Subaru DL may use the correct 155R13 size on paper and still present fitment issues if it has aftermarket wheels, altered ride height, changed springs, or body and suspension modifications. Even small changes on a compact car can affect space around the tire.
Wheel diameter is only one part of the picture. Owners should also verify wheel width, inspect steering and fender clearance lock-to-lock, and make sure nothing about the car’s current setup changes how the tire sits under load. That matters whether the Subaru is being restored or simply returned to regular road use.
What should I inspect before driving a 1981 Subaru DL on new tires?
Before driving a 1981 Subaru DL on new tires, inspect the wheels for damage or corrosion, confirm proper mounting for the 13-inch fitment, and check that the suspension and steering components are in sound condition. A fresh tire cannot compensate for worn hardware on an older car.
Road-readiness also includes practical tire checks after installation. Air pressure should be set correctly, wheel fasteners should be rechecked as appropriate, and the tires should be watched for rubbing, vibration, or uneven stance during the first miles. Those simple checks help confirm that the Subaru’s wheel and chassis setup still suits the tire.
How should 155R13 tires on a collector 1981 Subaru DL be maintained?
155R13 tires on a collector 1981 Subaru DL should be inspected regularly for air loss, sidewall cracking, cuts, bulges, and uneven tread wear. Low-mileage vintage cars often age their tires by time and storage conditions rather than by distance alone, so visual inspection matters as much as mileage.
Good maintenance also means protecting the car during storage. Keeping the Subaru away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and occasional pressure checks remain important even when the car is not driven often. Before a longer outing, a careful once-over is worth the effort on an older compact.
