The 1981 Dodge Aries arrived at the start of Chrysler’s front-wheel-drive K-car era, making practical, space-efficient transportation a defining part of its appeal. Today, that same no-nonsense character makes the Aries an interesting survivor for owners who value originality, everyday drivability, or a clean period presentation. Tire fitment for the 1981 Dodge Aries centers on three radial sizes: 175/75R13, 185/70R13, and 185/70R14. That gives owners choices not only in size and wheel diameter, but also in sidewall style and tire series where product options are available. The key is matching the tire to the car’s actual wheel setup and restoration or road-use goals.
Which Tire Size Is Right for The 1981 Dodge Aries
The 1981 Dodge Aries uses three primary tire sizes, and the first step is confirming which wheel diameter is on the car. Two of the sizes fit 13-inch rims, while one fits a 14-inch rim, so tire selection depends on the actual wheel setup before comparing tread style, sidewall appearance, and available product choices.
175/75R13 is a metric radial size in which 175 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 13 is the rim diameter in inches. On the 1981 Dodge Aries, this is one of the primary radial fitments for a 13-inch wheel. It represents a narrower, taller-profile metric format than the 185/70 alternatives used on the same model. Choosing this size starts with confirming that the car still has the correct 13-inch wheel and that the current setup has not been changed over the years.
185/70R13 is a metric radial size with a 185-millimeter nominal section width, a 70-series profile, and fitment for a 13-inch rim. For a 1981 Dodge Aries equipped with 13-inch wheels, this size opens up the broadest visible product choice, including blackwall, redline, and wide whitewall options across several tire series and brands. That makes it especially useful for owners balancing period-style appearance with modern replacement availability. The right choice still depends on matching the tire to the car’s actual wheel dimensions and the look the vehicle is meant to carry.
185/70R14 uses the same nominal section width and aspect ratio as 185/70R13, but it is built for a 14-inch rim rather than a 13-inch wheel. On a 1981 Dodge Aries, that makes wheel diameter the critical distinction before any purchase decision is made. Available choices in this size include blackwall and wide whitewall radials from several established brands and series, giving the owner some flexibility in both style and tire character. This size is best evaluated by confirming the current 14-inch wheel setup and comparing product details such as rim-width compatibility.
Tire fitment stays straightforward across the covered 1981 Dodge Aries sub-models because Base, Custom, and SE all use the same three primary radial sizes. Even so, checking the exact wheel diameter on the individual car still matters, since both 13-inch and 14-inch fitments are part of the Aries range.

1981 Dodge Aries Base
The 1981 Dodge Aries Base uses the same three primary radial sizes found across the model line, so the main fitment question is wheel diameter rather than trim level. Tire selection then becomes a matter of confirming whether the car wears 13-inch or 14-inch wheels and choosing the sidewall style or tire series that suits the car.
The 1981 Dodge Aries Custom shares the same radial fitment range as the other sub-models, including both 13-inch and 14-inch wheel applications. That means the important next step is verifying the actual wheel on the car before comparing available product options, appearance treatments, and other tire characteristics.
The 1981 Dodge Aries SE also uses the same three primary radial sizes, so trim level does not narrow the fitment by itself. Tire choice depends more on whether the car has a 13-inch or 14-inch wheel and whether the goal is a simple blackwall replacement or a more restoration-oriented sidewall presentation.
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.

Owners usually need to sort out wheel diameter first on a 1981 Dodge Aries, then compare radial sizes, sidewall styles, and product choices. The questions below focus on fitment, selection, appearance, and the checks worth making before the car returns to road use.
Tire Size & Fitment
What tire size fits a 1981 Dodge Aries?
The 1981 Dodge Aries uses three primary radial tire sizes: 175/75R13, 185/70R13, and 185/70R14. Two of those sizes fit 13-inch rims, while 185/70R14 fits a 14-inch rim, so the Aries does not have a single universal size across every wheel setup.
The practical decision starts at the car itself, not the trim badge alone. Checking the actual wheel diameter is essential before choosing a tire, especially on an older vehicle that may have had wheel changes over time. Once the wheel size is confirmed, the next comparison is sidewall style, tire series, and overall appearance for the intended use.
What size rim does a 1981 Dodge Aries use?
A 1981 Dodge Aries uses either a 13-inch or 14-inch rim, depending on the tire size on the car. The 175/75R13 and 185/70R13 sizes belong on 13-inch rims, while 185/70R14 is built for a 14-inch rim.
That distinction matters because a 13-inch tire and a 14-inch tire are not interchangeable simply because their widths look similar. Verifying the wheel diameter stamped on the rim or measuring the wheel correctly helps avoid ordering the wrong size. It is also worth checking wheel width, since available tire choices within the same size can carry different rim-width compatibility ranges.
Do all 1981 Dodge Aries sub-models use the same tire size?
The 1981 Dodge Aries Base, Custom, and SE share the same overall fitment range of 175/75R13, 185/70R13, and 185/70R14. In that sense, sub-model fitment is consistent across the covered Aries lineup rather than being unique to one trim.
Shared fitment range does not remove the need to inspect the actual car. One Aries may be on 13-inch wheels while another uses 14-inch wheels, and decades of replacement parts can complicate assumptions. The safest approach is to confirm the wheel diameter currently on the vehicle, then compare the available tire options within the correct size for the look and use you want.
Choosing the Right Tire
What should I consider when choosing a tire for a 1981 Dodge Aries?
Start with the correct primary size for the wheel on the car: 175/75R13, 185/70R13, or 185/70R14. All three are radial fitments, but the real differences involve wheel diameter, overall tire proportions, and how much product choice exists within each size.
After confirming size, compare the details that affect how the car will look and be used. Some Aries sizes have broader choices in brand, tire series, and sidewall treatment than others. Rim-width compatibility is also worth checking, especially on a survivor or modified car, because the right tire is not just about matching the size code on paper.
What sidewall styles are available for 1981 Dodge Aries tires?
For the 1981 Dodge Aries, available sidewall styles include blackwall, redline, and wide whitewall, depending on the tire size selected. Those choices appear in the product range for 185/70R13 and 185/70R14, giving owners flexibility between a straightforward replacement look and a more period-style presentation.
Sidewall style can change the character of the car more than many owners expect. A blackwall usually keeps the appearance restrained, while a redline or wide whitewall creates a stronger vintage visual statement. The right choice depends on the wheel size already on the car, the exact tire size being used, and whether the goal is restoration-minded appearance or simple road-ready function.
What brands offer tires for the 1981 Dodge Aries?
Tires for the 1981 Dodge Aries are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein in the supported product range. Those brands appear across 185/70R13 and 185/70R14, with several series represented rather than a single one-brand solution.
Brand choice should be considered alongside size, sidewall style, and the type of presentation you want from the car. Some options lean toward a traditional appearance, while others have a more performance-oriented or European-style character. A useful comparison includes rim-width compatibility, load information where stated, and how the tire’s sidewall treatment complements the Aries rather than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Dodge Aries?
A period-style 1981 Dodge Aries begins with the correct primary radial size for the wheel on the car, then narrows down by sidewall treatment and tire series. For owners using 185/70R13 or 185/70R14, the available range includes blackwall, redline, and wide whitewall options that can shift the car’s appearance in different directions.
The best choice depends on whether the car is being preserved as a clean survivor, refreshed as a street-driven classic, or styled to reflect a certain early-1980s look. Exact originality questions should be checked against marque references or period documentation. Tire size and wheel diameter still come first, since an appealing sidewall treatment means little if it is mounted on the wrong rim.
How does tire construction affect the appearance of a restored 1981 Dodge Aries?
On a restored 1981 Dodge Aries, construction is less of a visual dividing line than on older bias-ply-era vehicles because the primary fitments are already radial. The more visible appearance changes come from the tire’s sidewall treatment, proportions within the correct size, and the overall style of the tire series selected.
That means a restoration-minded owner should focus on the complete visual package rather than construction alone. A blackwall can keep the car understated, while a redline or wide whitewall creates a stronger period-inspired impression. Matching the tire to the confirmed wheel diameter is still essential, since the restored look can be thrown off quickly by using a 13-inch size on a car that actually wears 14-inch wheels.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Dodge Aries?
Yes, modifications can affect tire fitment on a 1981 Dodge Aries even when the tire size is one of the recognized primary sizes. Wheel swaps, changes in wheel width, aftermarket offsets, suspension alterations, or body changes can all influence how a tire sits and clears.
A car that has been lowered, updated with different wheels, or repaired over the years may not match its original setup closely enough for assumptions to be safe. Measuring the actual wheel diameter and width, then checking clearance at the fender, steering, and suspension points, is a better approach than relying only on the model name when selecting replacement tires.
What should I inspect before driving a 1981 Dodge Aries on new tires?
Before driving a 1981 Dodge Aries on new tires, inspect the wheels for damage or excessive corrosion and make sure the wheel diameter matches the tire being installed. It is also wise to check alignment condition, suspension wear, brake condition, and valve stems so the new tires are not asked to compensate for other problems.
A collector-era compact may spend long periods parked, so age-related issues matter as much as mileage. Look over the old tires for cracking, bulges, irregular wear, and signs of air loss, then verify clearances once the new tires are mounted. A short test drive followed by a recheck of pressure and visible clearance can catch problems early.
How should tires on a collector 1981 Dodge Aries be maintained?
Tires on a collector 1981 Dodge Aries should be maintained with regular pressure checks, routine visual inspection, and attention to age as well as tread depth. Even a low-mileage car can develop problems from long storage, including sidewall cracking, flat spotting, or slow air loss that may not be obvious at a glance.
Storage conditions make a difference, especially for a vehicle that is driven occasionally rather than daily. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and moving or driving it periodically can help avoid long-term flat spotting. Before a longer trip, confirm inflation, inspect for damage, and recheck that the tires still have proper clearance on the current wheel setup.
