The 1987 Dodge Diplomat belongs to the last wave of traditional American rear-wheel-drive sedans, a format valued today for its straightforward mechanical layout, square-shouldered styling, and familiar full-size road manners. Whether kept as a clean survivor or maintained as a dependable cruiser, tire choice has a big effect on both stance and character. The 1987 Dodge Diplomat uses a 205/75R15 radial tire on a 15-inch rim. Within that size, there is room to choose between blackwall-adjacent classic radials, whitewall treatments, goldline, and redline presentations from several vintage-focused series. The right choice comes down to the look you want, the wheel you actually have, and how the car will be driven.
Which Tire Size Is Right for The 1987 Dodge Diplomat
The 1987 Dodge Diplomat uses one primary tire size: 205/75R15. It is a radial fitment on a 15-inch rim, and that same size is shared across the covered SE and Salon sub-models. With size selection being straightforward, the real decision shifts to sidewall style, tire series, brand preference, and confirming that the wheel on the car still matches the intended 15-inch setup.
A 205/75R15 tire uses a 205-millimeter nominal section width, a 75-series aspect ratio, radial construction, and fits a 15-inch wheel. On the 1987 Dodge Diplomat, this is the primary fitment and suits the car's later-era radial tire design rather than an earlier bias-ply setup. Available choices include BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar, with sidewall styles ranging from narrow and wide whitewalls to goldline and redline across several tire series. That gives Diplomat owners flexibility to match original-era character, custom appearance, or general road-use priorities while staying in the correct base size.
Tire fitment is straightforward across the covered 1987 Dodge Diplomat sub-models. Both the SE and Salon use the same 205/75R15 radial size, so the main choice is not sub-model sizing but which sidewall style, brand, and tire series best suits the car.

Tire Size & Fitment
What tire size fits a 1987 Dodge Diplomat?
The 1987 Dodge Diplomat uses a 205/75R15 radial tire. That size applies to the covered SE and Salon sub-models, making fitment simpler than on vehicles that split tire sizes by trim level or wheel package.
Since the primary size is consistent, the next step is confirming that the car still has the expected 15-inch wheels and has not been changed to an aftermarket setup. Once size is verified, the real comparison becomes sidewall treatment, tire series, rim-width compatibility, and the overall look you want for the Diplomat.
What size rim does a 1987 Dodge Diplomat use?
The 1987 Dodge Diplomat uses a 15-inch rim with its 205/75R15 tire size. The tire size itself confirms the 15-inch wheel diameter, and the available products for this application are built around that same rim diameter.
Wheel diameter is only part of the fitment picture, so it also helps to confirm the actual wheel width before choosing among available tires. Many 205/75R15 options in this fitment range are intended for wheels in the 5 to 7.5 inch range, depending on the specific tire design.
Do all 1987 Dodge Diplomat sub-models use the same tire size?
The covered 1987 Dodge Diplomat sub-models share the same tire size. Both the SE and the Salon use a 205/75R15 radial, so there is no trim-level split in primary tire size within this fitment group.
That consistency makes shopping easier, but it is still wise to inspect the car before ordering replacement tires. Older sedans are often changed over the years, and wheel swaps or suspension changes can alter what is currently on the vehicle even when the original-size replacement remains 205/75R15.
Choosing the Right Tire
What should I consider when choosing a 205/75R15 tire for a 1987 Dodge Diplomat?
Start with the basics: correct size, radial construction, and a 15-inch wheel. From there, compare the tire's sidewall style, tire series, rim-width specification, and load information where it is given, since those details shape both the car's appearance and how closely the tire matches your intended use.
A Diplomat kept in stock-looking form may call for a whitewall presentation, while a different build may suit goldline or redline styling better. It also helps to check the wheel on the car before choosing, because some available 205/75R15 products are intended for slightly different rim-width ranges than others.
What sidewall styles are available for 1987 Dodge Diplomat tires?
The 1987 Dodge Diplomat's 205/75R15 fitment is available in several sidewall treatments, including narrow whitewall, wide whitewall, goldline, and redline. Those choices let the same basic tire size present very differently depending on whether the goal is understated, luxury-oriented, or more distinctive period-style character.
Sidewall appearance should be chosen with the whole car in mind, including wheel covers, paint color, trim, and the overall personality of the build. Keeping the correct size constant allows the visual decision to take center stage, but it remains important to confirm the selected tire's wheel-width suitability before finalizing the choice.
What brands offer tires for the 1987 Dodge Diplomat?
Available 205/75R15 tires for the 1987 Dodge Diplomat include options from BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar. These appear across several vintage and classic-oriented radial series, giving buyers a wider spread of appearance choices within the same fundamental fitment.
Brand alone should not be the only deciding factor. A better comparison looks at the combination of brand, sidewall style, tire series, and wheel-width compatibility so the tire matches both the car's visual direction and the actual wheel setup being used on the Diplomat.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Dodge Diplomat?
A period-style 1987 Dodge Diplomat starts with the correct 205/75R15 radial size, then moves into appearance choices such as narrow whitewall, wide whitewall, goldline, or redline. Since this is already a radial-era sedan, the main restoration-minded decision is usually visual character rather than choosing between older and newer construction types.
The most suitable tire depends on how the car is being presented. A clean survivor, formal sedan look, or more personalized build can each point toward a different sidewall treatment, so photos, original literature, and marque-specific references are useful if exact period presentation matters to the project.
Does correct tire fitment matter for a 1987 Dodge Diplomat restoration?
Correct tire fitment matters because it affects the car's stance, proportions, and overall authenticity of presentation. On a 1987 Dodge Diplomat, staying with the proper 205/75R15 radial size preserves the basic visual balance intended for the car far better than using an arbitrary substitute size.
Appearance is only part of the story. Proper size also helps keep wheel compatibility and body clearance in the expected range, which is especially important on a restoration where wheel covers, trim, and ride height all contribute to the finished look. A mismatched size can change that impression quickly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Dodge Diplomat?
Yes. A 1987 Dodge Diplomat may originally use 205/75R15 tires, but wheel changes, altered ride height, suspension work, or body modifications can change the fitment picture. Even when the replacement tire remains in the correct base size, the car's actual wheel width and available clearance still need to be checked.
This matters most on cars that have had aftermarket wheels installed or have been lowered over time. Tire selection should account for the real wheel-and-body setup now on the vehicle, not just the original-size reference, so steering clearance and fender clearance deserve a close look before road use.
What should I inspect before driving a 1987 Dodge Diplomat on new tires?
Before regular road use, inspect the wheels for correct diameter and condition, verify that the new tires are seated properly, and check inflation pressure carefully. It also helps to look over suspension and steering components, since worn front-end parts can affect how a full-size rear-wheel-drive sedan tracks and feels on fresh tires.
A short test drive should include listening for rubbing, checking straight-line behavior, and making sure there is no contact at full steering lock. Older collector vehicles often sit for long periods, so confirming even air retention and rechecking the tires after the first few drives is a sensible habit.
How should 205/75R15 tires on a collector 1987 Dodge Diplomat be maintained?
Collector-car tires in 205/75R15 should be inspected regularly for air loss, cracking, bulges, cuts, and uneven tread wear. A 1987 Dodge Diplomat that spends long periods parked can age tires through time and storage conditions even when it is not accumulating many miles.
Consistent inflation, clean storage conditions, and periodic movement of the car all help preserve tire condition. Keeping the vehicle away from prolonged sun, heat, moisture, and ozone sources is also worthwhile, and any tire showing visible age-related deterioration should be evaluated before the Diplomat returns to regular driving.
