1981 Subaru Trucks Brat Tires

The 1981 Subaru Trucks Brat uses two different radial tire sizes depending on sub-model. The DL uses 165R13, while the GL uses 185/70R13. Both sizes are built for 13-inch wheels, but they are not the same fitment and should not be treated as interchangeable simply because the rim diameter matches.

The most important step is confirming whether the truck is a DL or a GL before comparing tires. After that, check the actual wheel width, overall tire condition, and any prior wheel or suspension changes, since older Brats are often modified over time and that can affect what size remains appropriate.

Both tire sizes used on the 1981 Subaru Trucks Brat are built around a 13-inch rim diameter. The DL’s 165R13 and the GL’s 185/70R13 each mount on a 13-inch wheel, so the main fitment difference between trims is tire size rather than wheel diameter.

Rim diameter is only part of the picture on an older utility vehicle like the Brat. Wheel width still matters, especially when comparing different tire series, so it is smart to confirm the actual wheel dimensions on the truck before selecting a tire, particularly if the original wheels have been replaced at some point.

The 1981 Subaru Trucks Brat has more than one tire size because fitment varies by sub-model. The DL uses 165R13, while the GL uses 185/70R13. Both are radial sizes for 13-inch rims, but they represent different sizing conventions and different trim-level fitment requirements.

That means tire selection starts with the badge on the truck, not just the wheel diameter. It also helps to compare the tires already on the vehicle against the intended sub-model fitment, since many surviving Brats have changed hands for decades and may no longer be wearing the size that matches their trim.

Start with the correct sub-model size, because the 1981 Subaru Trucks Brat does not use one universal tire. The DL takes 165R13 and the GL takes 185/70R13, both in radial construction. From there, compare the available tire series, brand choices, sidewall treatment, and wheel-width compatibility where that specification is given.

Appearance and intended use matter almost as much as size on a vintage compact truck. A stock-looking restoration may call for a traditional blackwall presentation, while a GL owner might want a redline or wide whitewall style. It also helps to review load figures, tire weight, and how the truck will actually be driven.

Sidewall style depends on the size used by the truck’s sub-model. In 165R13, the available choices are blackwall. In 185/70R13, the selection broadens to blackwall, redline, and wide whitewall, giving GL owners more flexibility in how the truck presents visually while staying within the proper size category.

That makes sidewall choice more of an appearance decision than a fitment decision, as long as the correct size comes first. A blackwall usually keeps the look understated and utility-minded, while redline or wide whitewall changes the truck’s character more noticeably. Sidewall style should complement the Brat’s wheels and overall build direction.

Brand selection varies by size on the 1981 Subaru Trucks Brat. The 165R13 fitment is available from Michelin and Dunlop. The 185/70R13 fitment expands the field with BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, along with several distinct tire series inside that larger size category.

Brand is best used as one part of the decision rather than the only one. It helps to compare the exact tire series, sidewall appearance, rim-width specification where stated, and any load information shown for the size you need. That approach keeps the choice centered on the truck’s fitment and the owner’s goals.

A period-style 1981 Subaru Trucks Brat starts with the correct trim-specific size. That means 165R13 for the DL and 185/70R13 for the GL, both in radial construction. From there, a traditional blackwall presentation usually gives the most understated vintage-import look, while the GL’s 185/70R13 fitment allows more visible style variation.

The best appearance choice depends on whether the truck is being preserved, mildly personalized, or restored with stronger visual cues. Matching the tire’s overall character to the wheel style matters as much as the size itself. When exact originality is important, compare tire appearance details against marque references and period photos.

On the 1981 Subaru Trucks Brat, construction is straightforward because the primary fitments are radial rather than bias-ply. That means the visual difference in a restored truck is driven more by the size used on the correct sub-model and by the sidewall treatment than by a bias-ply-versus-radial decision.

The DL’s 165R13 blackwall fitment supports a simple, tidy period-style look, while the GL’s 185/70R13 opens the door to blackwall, redline, or wide whitewall styling. A restored Brat tends to look most cohesive when the tire profile and sidewall presentation match the truck’s trim level, wheels, and intended era impression.

Yes, modifications can affect tire fitment on a 1981 Subaru Trucks Brat even when the correct original-type size is known. Aftermarket wheels, different wheel widths, suspension changes, and body alterations can all change how a 165R13 or 185/70R13 tire sits in the wheel opening and how much clearance is available.

A Brat that has been lifted, lowered, or fitted with non-original wheels should be measured rather than judged by trim alone. Check wheel diameter and width first, then inspect steering clearance and the space around the fenders and suspension components. That is especially important before moving from one trim-specific size to another.

Before driving a 1981 Subaru Trucks Brat on new tires, confirm that the truck is wearing the correct DL or GL size and that the wheels are in sound condition. It is also wise to inspect valve stems, wheel hardware, and basic alignment condition so the new tires are not compromised by older supporting parts.

A short visual check of the rest of the vehicle helps prevent avoidable problems on an older truck. Look for rubbing marks inside the wheel openings, uneven wear clues from previous tires, and any suspension looseness that could affect tracking. Tire pressure should also be set correctly before the truck returns to regular road use.

Tires on a collector 1981 Subaru Trucks Brat should be inspected regularly for air loss, cracking, cuts, bulges, and uneven tread wear, even if the truck is driven infrequently. Low-mileage vintage vehicles often age their tires through time and storage conditions rather than through heavy road use alone.

Storage habits make a real difference with an older Brat. Keeping the truck away from prolonged sun, excessive heat, moisture, and ozone sources helps preserve the tires between drives. It also pays to check pressures before each outing and to look over the wheels and suspension periodically, especially after long periods of inactivity.
