1979 Subaru DL Tires

A 1979 Subaru DL uses either 155R13 or 6.15-13, depending on the specific sub-model. The 155R13 is a radial tire size, while 6.15-13 is a numeric bias-ply size. Both fit 13-inch rims, but they are not simply different ways of writing the same tire. The 4WD DL uses 155R13, while the 2-door and 4-door DL models may use either size.

That makes the first step confirming exactly which DL version is in front of you and checking what wheel and tire setup is already on the car. A previous owner may have changed tires or wheels over the years, so the current equipment should match the intended fitment before selecting a replacement.

The 1979 Subaru DL uses a 13-inch rim with both of its primary tire sizes. That applies to the 155R13 radial fitment and the 6.15-13 bias-ply fitment. Even though the construction and sizing format differ, the shared wheel diameter remains 13 inches across these tire applications.

Wheel diameter is only one part of the fitment picture, so the wheel should still be checked for width and any changes from stock-type hardware. On a car of this age, aftermarket wheels or swapped steel wheels are common enough that verifying the actual rim before mounting tires is a smart step.

No, the 1979 Subaru DL does not use one universal tire size across every covered sub-model. The 4WD model uses 155R13 radial tires, while the 2 Dr. and 4 Dr. versions can use either 155R13 radial or 6.15-13 bias-ply tires. That means size selection is tied to the exact configuration rather than the DL badge alone.

This matters because the buying decision changes once the sub-model is identified. A 4WD owner can focus on selecting the right 155R13 radial product, while a 2-door or 4-door owner may need to decide whether to stay with a traditional bias-ply setup or use the radial size already associated with the model.

On the 1979 Subaru DL, 6.15-13 is a bias-ply tire size. It uses a vintage numeric sizing system, and the dash-format size reflects a traditional bias-ply construction rather than a modern radial format. This fitment appears on the 2 Dr. and 4 Dr. DL models, not on the 4WD version.

That distinction affects both appearance and replacement planning. A buyer looking to preserve a more traditional period-style look may prefer to remain with the bias-ply size, while anyone comparing alternatives should first verify the car’s actual wheel setup and whether the current tire construction matches the intended use.

155R13 is a radial tire size for the 1979 Subaru DL. In this size format, the R identifies radial construction, and the tire fits a 13-inch rim. It is the fitment used on the 4WD DL, and it also appears on the 2 Dr. and 4 Dr. versions alongside the alternate 6.15-13 bias-ply size.

For a buyer, that means 155R13 is the relevant path when the car is already set up around a radial tire or when the sub-model calls for that fitment. It is still worth checking wheel width, overall vehicle condition, and clearance if the car has been altered from its original wheel and suspension arrangement.

That choice depends on the specific DL sub-model and the kind of ownership goal attached to the car. The 1979 Subaru DL uses both constructions across its fitments: 155R13 in radial form and 6.15-13 in bias-ply form. A 4WD model points directly toward the radial size, while some 2-door and 4-door cars may reasonably be evaluated either as radial-equipped or bias-ply-equipped setups.

Bias-ply usually matters most when traditional appearance is part of the plan, while radial selection often centers on using the radial size already tied to the vehicle. The safest buying approach is to confirm the exact sub-model, wheel size, and current setup first, then choose the tire construction that matches the car’s intended presentation and road use.

Start with the exact vehicle configuration, because 155R13 is the required fitment for the 4WD DL and one of the applicable sizes for the 2 Dr. and 4 Dr. models. From there, compare radial construction details, blackwall appearance, tire series, and wheel compatibility. Michelin and Dunlop both offer 155R13 choices for this Subaru in period-appropriate radial form.

Selection becomes easier once the intended use is clear. A restoration-oriented car may emphasize brand character and presentation, while a regularly driven example may place more weight on practical product details such as rim-width range, load information where stated, and the condition of the existing 13-inch wheels.

For the available 155R13 radial products tied to the 1979 Subaru DL, the sidewall style is blackwall. That keeps the look simple and in character with a compact late-1970s Subaru. Among the current radial product choices in this size, there is not a spread of whitewall, redline, or raised white letter variations to compare.

That means the choice within 155R13 is less about sidewall decoration and more about brand, tire series, and wheel compatibility. Buyers considering the alternate 6.15-13 bias-ply fitment should keep appearance goals in mind, but the first task remains confirming which of the DL sub-models and wheel setups the car actually has.

For the 155R13 radial fitment used on the 1979 Subaru DL, available products come from Michelin and Dunlop. Michelin offers the XAS-FF series, while Dunlop offers the SP Sport Aquajet. Both are blackwall radial choices in the 13-inch size associated with this Subaru fitment.

Brand should be considered alongside the rest of the specification rather than by name alone. The better comparison points are the correct size, construction, wheel compatibility, and the kind of period-style presentation you want the car to have. Those factors do more to narrow the right choice than a brand label by itself.

A period-style choice for a 1979 Subaru DL starts with the fitment that matches the exact sub-model and the way the car is equipped today. That could mean a 155R13 radial for a 4WD DL or either 155R13 radial or 6.15-13 bias-ply for certain 2-door and 4-door cars. The right period-style direction depends on whether the goal is a traditional bias-ply presentation or a late-1970s radial look.

Appearance should be considered together with wheel setup and how strictly the car is being restored. A buyer chasing exact historical authenticity should compare the tire choice against marque references, old photos, and vehicle-specific documentation, while a driver-quality restoration can focus more on staying within the correct size family and visual character.

Tire construction changes the visual character of a restored 1979 Subaru DL even when the wheel diameter stays the same. A 6.15-13 bias-ply setup gives the car a more traditional, earlier-style presentation, while a 155R13 radial keeps the Subaru within the compact radial era it also occupied. On this model, the difference is as much about stance and visual tone as it is about specification.

That is why construction should be chosen deliberately rather than as an afterthought. Buyers restoring a 2-door or 4-door DL have room to evaluate both paths, while a 4WD owner is centered on the radial fitment. The final look should still be checked against the actual wheel setup and the overall restoration goal.

Yes, modifications can affect tire fitment on a 1979 Subaru DL even when the tire size itself appears correct. Changes to wheel width, wheel design, suspension height, or body clearance can alter how a 155R13 or 6.15-13 tire sits on the car. That is especially important on older compact cars, where small dimensional changes can matter more than expected.

A Subaru DL with aftermarket wheels or altered suspension should be checked carefully before replacement tires are chosen. Confirm the actual rim diameter, verify that the wheel width suits the tire being considered, and look at steering, fender, and suspension clearance with the car at normal ride height.

Before driving a 1979 Subaru DL on new tires, inspect the wheels, valve stems, lug hardware, and overall condition of the suspension and steering components. Tire pressure should be set correctly, and the new tires should be checked for proper seating and clearance. It also helps to confirm that the installed size matches the car’s actual sub-model and wheel arrangement.

A cautious first road test is worthwhile on any older Subaru, especially one that has spent long periods parked. Watch for rubbing, pulling, vibration, or unusual steering response, and recheck pressure after the initial drive. Catching those issues early is better than assuming a correct size alone guarantees the whole setup is sorted.

Tires on a collector 1979 Subaru DL should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, bulges, and signs of age-related deterioration. Low-mileage collector cars often wear old tires long after they stop being roadworthy, so condition matters just as much as tread depth. Keeping the correct pressure also helps preserve shape and drivability.

Storage habits make a real difference on a lightly used car. Parking away from prolonged sunlight, moisture, and ozone sources can help protect the tire casing, and occasional movement helps avoid long-term flat spotting. Before any longer drive, the Subaru should get a fresh visual inspection and a pressure check rather than relying on last season’s condition.
