The 1977 Peugeot 504 occupies a distinctive place among European sedans and wagons of the period, known for its durable engineering, long-distance comfort, and understated French character. By this stage in the model’s life, the 504 had earned a reputation as a practical touring car rather than a flashy specialty machine. Tire fitment centers on two 14-inch radial sizes, with 175R14 used on sedans and 185R14 used on wagons. That gives owners a meaningful choice in period-appropriate radial designs, including blackwall and narrow whitewall options from Michelin, Vredestein, and Phoenix. The right selection comes down to matching the exact body style, preserving the car’s appearance, and confirming wheel compatibility.
Which Tire Size Is Right for The 1977 Peugeot 504
The 1977 Peugeot 504 uses two primary tire sizes, and the correct one depends on whether the car is a sedan or a wagon. Both sizes are radial tires built for 14-inch wheels, so the first step is confirming the exact sub-model before comparing tire series, sidewall appearance, and other product details.
175R14 is a Euro-metric radial size in which 175 refers to nominal section width in millimeters, R indicates radial construction, and 14 designates a 14-inch wheel. On the 1977 Peugeot 504, this size is used on the sedan and reflects the classic metric sizing common on European cars of the era. Available choices include Michelin XAS plus Vredestein Sprint Plus and Sprint Classic, all in blackwall form. This size suits buyers who are maintaining the sedan’s proper fitment and want to compare traditional European-style radial options within that specification.
185R14 is also a Euro-metric radial size, with a nominal width of 185 millimeters, radial construction, and a 14-inch rim diameter. For the 1977 Peugeot 504, this size belongs to the wagon models and represents a different fitment from the sedan. Product choices include blackwall and narrow whitewall versions, with offerings from Michelin, Phoenix, and Vredestein across series such as MXV and Sprint Classic. This is the size to evaluate when the goal is keeping the wagon on its correct primary fitment while choosing the right appearance and product style.
Sub-model fitment on the 1977 Peugeot 504 is straightforward once the body style is confirmed. Sedans use one tire size, wagons use another, so identifying the exact version matters before selecting a tire.

1977 Peugeot 504 Sedan (Diesel)
The 1977 Peugeot 504 Sedan (Diesel) uses the 175R14 radial tire size on a 14-inch wheel. Tire selection here is mainly about choosing among period-style blackwall radial options while keeping the sedan on its proper size.
The 1977 Peugeot 504 Sedan (Gas) also uses the 175R14 radial tire size. That keeps the decision focused on tire series and brand choice rather than size changes, provided the car still has the correct wheel setup.
The 1977 Peugeot 504 Wagon (Diesel) uses the larger 185R14 radial size. Buyers choosing for a wagon should stay focused on that fitment and then compare blackwall versus narrow whitewall presentation among the available products.
The 1977 Peugeot 504 Wagon (Gas) uses 185R14 radials on 14-inch wheels. That means tire choice is less about alternate primary sizes and more about selecting the right sidewall style and tire series for the wagon’s intended look and use.
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)

Tire Size & Fitment
What tire size fits a 1977 Peugeot 504?
A 1977 Peugeot 504 uses either 175R14 or 185R14, depending on the sub-model. The sedan uses 175R14, while the wagon uses 185R14. Both are radial tire sizes designed for 14-inch wheels, which keeps the construction type consistent even though the vehicle line uses two distinct sizes.
The most important step is confirming whether the car is a sedan or wagon before choosing a tire. Once that is settled, the next comparison points are brand, tire series, sidewall style, and wheel-width compatibility, especially if the car has replacement wheels or has been altered from its original setup.
What size rim does a 1977 Peugeot 504 use?
The 1977 Peugeot 504 uses 14-inch rims with both of its primary tire sizes. The sedan’s 175R14 and the wagon’s 185R14 are both built around a 14-inch wheel diameter, so the rim diameter stays the same across the covered sub-models even though the tire width changes.
That does not mean every 14-inch wheel is automatically suitable. Wheel width still matters, and some available tires include specific rim-width ranges, such as 4.5 to 6.0 inches or up to 6.5 inches depending on the tire. Checking the actual wheel on the car helps avoid mounting a correct-size tire on an unsuitable rim.
Why does the 1977 Peugeot 504 have more than one tire size?
The 1977 Peugeot 504 has more than one tire size because fitment changes by sub-model. Sedan versions use 175R14, while wagon versions use 185R14. Both are period-appropriate Euro-metric radial sizes, but they are not the same primary fitment across the model range.
That difference means the buyer should identify the exact body style before comparing products. A wagon owner may also see a broader appearance choice, including narrow whitewall options in 185R14, while sedan owners selecting 175R14 will mainly be comparing blackwall radial offerings and tire series.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1977 Peugeot 504?
Choosing a 175R14 tire for a 1977 Peugeot 504 starts with confirming that the car is one of the sedan sub-models. In that size, available choices include Michelin XAS along with Vredestein Sprint Plus and Sprint Classic, all as radial blackwall tires on 14-inch fitment.
After confirming the correct size, compare the tire series, the intended look, and any rim-width details tied to the tire. On a sedan that is driven regularly, that may steer the decision toward a classic European radial design, while a more appearance-focused project may place greater emphasis on period-style presentation and brand preference.
What sidewall styles are available for 1977 Peugeot 504 tires?
Sidewall style depends on the tire size used by the 1977 Peugeot 504. In 175R14, the available products are blackwall. In 185R14, both blackwall and narrow whitewall options are available, giving wagon owners a broader appearance choice within the correct primary size.
That matters most for buyers balancing visual style with proper fitment. A blackwall usually preserves a restrained European look, while a narrow whitewall gives the wagon a different period-style presentation. The sidewall choice should come after confirming the correct sedan or wagon tire size, not before.
What brands offer tires for the 1977 Peugeot 504?
Michelin, Vredestein, and Phoenix all offer tires for the 1977 Peugeot 504, depending on the size. Michelin appears in both 175R14 and 185R14 fitments, Vredestein also covers both sizes, and Phoenix is available in 185R14 with a narrow whitewall presentation.
Brand selection is only one part of the decision. It still helps to compare the exact tire series, sidewall treatment, and wheel-width compatibility for the size your Peugeot uses. A sedan owner and a wagon owner may see different brand and appearance combinations even though both vehicles use 14-inch radial tires.
Restoration & Appearance
Which tire should I choose for a period-style 1977 Peugeot 504?
A period-style choice for a 1977 Peugeot 504 begins with the correct primary size: 175R14 for a sedan and 185R14 for a wagon. From there, classic European radial offerings such as Michelin XAS, Michelin MXV, or Vredestein Sprint Classic fit the character of the car without forcing a move away from the proper sizing format.
Appearance should be matched to the specific project. A restrained blackwall often suits the 504’s original era and design language, while a narrow whitewall can create a more tailored vintage presentation on a wagon. Buyers chasing exact originality should still compare tire appearance against marque-specific historical references for their particular car.
How does tire construction affect the appearance of a restored 1977 Peugeot 504?
Tire construction is less of a style debate here because the 1977 Peugeot 504 uses radial primary fitments in both 175R14 and 185R14. That keeps the restored look rooted in the metric radial proportions associated with European cars of the period rather than a bias-ply presentation.
The visual differences come more from tire series and sidewall treatment than from switching between construction types. On this Peugeot, the main appearance decision is usually blackwall versus narrow whitewall where available, along with choosing a radial line whose tread and sidewall styling complement the restoration rather than overpower it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1977 Peugeot 504?
Yes, modifications can affect tire fitment on a 1977 Peugeot 504 even when the correct primary size is known. Aftermarket wheels, different wheel widths, suspension changes, ride-height alterations, or body repairs can all change how a 175R14 or 185R14 tire sits within the wheel opening and against steering components.
A modified car should be checked for wheel diameter, wheel width, and clearance before a tire is chosen. That is especially important when moving between sedan and wagon sizes or when the car no longer carries its original-style wheels. A correct size on paper still needs to suit the car’s actual physical setup.
What should I inspect before driving a 1977 Peugeot 504 on new tires?
Before driving a 1977 Peugeot 504 on new tires, inspect the wheels for correct diameter and condition, confirm the tires are mounted in the proper sedan or wagon size, and look over the valve stems, balance, and general installation quality. A quick visual check for even seating on the rim is also worthwhile.
Roadworthiness depends on more than fresh rubber. The car should also be checked for alignment-related wear patterns, suspension looseness, brake drag, and any contact points that could affect clearance during turning or compression. Collector cars that sit for long periods benefit from a slow shakedown drive and a pressure recheck afterward.
How should 175R14 and 185R14 tires on a collector 1977 Peugeot 504 be maintained?
Collector-car tire maintenance for a 1977 Peugeot 504 starts with routine pressure checks, regular visual inspection, and attention to age-related deterioration. Whether the car uses 175R14 or 185R14, the owner should watch for cracking, bulges, cuts, uneven tread wear, and slow air loss, especially if the vehicle is driven infrequently.
Storage conditions matter as much as mileage on an older hobby car. Keeping the Peugeot away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, while occasional movement can reduce flat spotting from long stationary periods. Seasonal inspection is a good habit even when the car sees only limited road use.
