The 1975 Peugeot 504 occupies a distinctive place among mid-1970s European cars, known for its durable engineering, long-distance comfort, and understated style. Whether kept as a sedan or wagon, the 504 rewards owners who pay close attention to the details that shape its road manners and stance. Tire fitment centers on two radial sizes, 175R14 and 185R14, both built for 14-inch rims, with size choice tied to the specific body configuration. Available options include traditional blackwall designs as well as narrow whitewall selections, giving owners room to balance original character, touring use, and the exact look they want from a restoration-minded or road-ready car.
Which Tire Size Is Right for The 1975 Peugeot 504
The 1975 Peugeot 504 uses two primary tire sizes, and the correct one depends on the specific sub-model. Both sizes are radial tires for 14-inch rims, so the main fitment step is confirming whether the car is a sedan or wagon before comparing tire series, sidewall style, and other product details. Once the correct size is established, the decision shifts to appearance and product character rather than construction type.
A 175R14 size uses a nominal section width of 175 millimeters, radial construction, and a 14-inch rim diameter; in this format, the aspect ratio is not stated and is commonly associated with an 80-series profile. On the 1975 Peugeot 504, this is a classic radial fitment used on the sedan configurations. Available choices include Michelin and Vredestein offerings in series such as XAS, Sprint Plus, and Sprint Classic, all with blackwall presentation. This size suits buyers who are matching the sedan's original fitment pattern and want to compare period-style touring character across established European tire lines.
A 185R14 tire follows the same Euro-metric radial format, but with a nominal section width of 185 millimeters on a 14-inch rim. For the 1975 Peugeot 504, this size belongs with the wagon versions, making sub-model identification more important than construction choice because both primary sizes are radial. Product selection includes blackwall and narrow whitewall options from Michelin, Phoenix, and Vredestein, with series such as Michelin MXV and Vredestein Sprint Classic. This size is the one to evaluate when preserving the wagon's intended fitment while choosing between a more understated European look and a brighter whitewall presentation.
Sub-model fitment matters on the 1975 Peugeot 504 because sedan and wagon versions do not share the same tire size. The construction stays radial across the range, but identifying the exact body style is the first step before choosing a tire.

1975 Peugeot 504 Sedan (Diesel)
The 1975 Peugeot 504 Sedan (Diesel) uses the narrower of the two primary 14-inch radial fitments. That keeps the tire decision focused on selecting the right blackwall product line and confirming wheel compatibility rather than sorting through multiple construction types.
The 1975 Peugeot 504 Sedan (Gas) follows the same tire-fitment pattern as the diesel sedan, using the sedan-specific radial size on a 14-inch rim. Tire selection is mainly about choosing among the available European-style blackwall options while keeping the correct sedan fitment in place.
The 1975 Peugeot 504 Wagon (Diesel) uses the larger of the two primary radial sizes offered for this model year. That opens the door to both blackwall and narrow whitewall choices, so owners can weigh appearance along with wheel-width and general fitment checks.
The 1975 Peugeot 504 Wagon (Gas) shares the wagon tire-fitment pattern rather than the sedan setup. Choosing the correct wagon size first is essential, then the decision becomes whether a blackwall or narrow whitewall tire better suits the car'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)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1975 Peugeot 504?
A 1975 Peugeot 504 uses either 175R14 or 185R14 tires, depending on the sub-model. Sedan models, including Sedan (Diesel) and Sedan (Gas), use 175R14 radial tires. Wagon models, including Wagon (Diesel) and Wagon (Gas), use 185R14 radial tires.
The key step is identifying whether the car is a sedan or wagon before choosing a tire. Both sizes fit 14-inch rims, so the fitment decision is less about wheel diameter and more about making sure the body style, wheel width, and overall setup still match the original tire-size pattern.
What size rim does a 1975 Peugeot 504 use?
The 1975 Peugeot 504 uses 14-inch rims with both of its primary tire sizes. The sedan's 175R14 and the wagon's 185R14 are both designed around the same 14-inch rim diameter, even though the tires differ in nominal width.
That shared rim diameter simplifies selection, but it does not make the two tire sizes interchangeable across all versions of the car. Wheel width should still be checked against the tire being considered, especially if the 504 has aftermarket wheels or if the car's current wheel setup no longer matches its original sedan or wagon configuration.
Do all 1975 Peugeot 504 sub-models use the same tire size?
No, the 1975 Peugeot 504 does not use one tire size across every sub-model. Both sedan versions use 175R14 radial tires, while both wagon versions use 185R14 radial tires. The split is by body style rather than by fuel type.
That means a buyer should confirm the exact sub-model first, then compare tire choices within the correct size. A sedan owner can focus on 175R14 options, while a wagon owner should stay within 185R14 offerings and then sort through blackwall or whitewall appearance, tire series, and wheel-width compatibility.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1975 Peugeot 504?
For a 1975 Peugeot 504 that uses 175R14, the main considerations are staying with the correct sedan size, confirming 14-inch wheel compatibility, and choosing among the available radial product lines. Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic are all part of the 175R14 selection, and each presents a blackwall appearance.
Once size is settled, compare details that affect how the tire suits the car's use and presentation, such as rim-width range, weight, load specification where stated, and the overall character of the tire series. That approach keeps the focus on a proper sedan fitment while still allowing a meaningful choice within the available 175R14 radials.
What sidewall styles are available for 1975 Peugeot 504 tires?
Sidewall choice depends on which tire size your 1975 Peugeot 504 uses. The 175R14 sedan fitment is available in blackwall form. The 185R14 wagon fitment adds more appearance variety, with both blackwall and narrow whitewall options available.
That makes sidewall style part of the decision only after the correct size is confirmed. A buyer restoring or preserving a restrained European look may prefer blackwall, while narrow whitewall can create a more dressed presentation on the wagon. The right choice is the one that suits the car's intended appearance without stepping outside the correct size and wheel fitment.
What brands offer tires for the 1975 Peugeot 504?
Tires for the 1975 Peugeot 504 are available from Michelin, Vredestein, and Phoenix, depending on size. The 175R14 fitment includes Michelin and Vredestein options, while the 185R14 fitment includes Michelin, Vredestein, and Phoenix products.
Brand choice should come after size confirmation, since the sedan and wagon do not use the same tire. It also helps to compare the tire series and sidewall treatment within each brand's offering rather than choosing by name alone. That is especially useful on a collector-era Peugeot where appearance, wheel compatibility, and intended road use all matter.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Peugeot 504?
A period-style 1975 Peugeot 504 tire choice starts with the correct body-style fitment: 175R14 for sedans and 185R14 for wagons. Because both primary sizes are radial, the decision is less about changing construction and more about selecting a tire series and sidewall treatment that suits the car's era and intended presentation.
Michelin and Vredestein options give the 504 a distinctly European feel, while the wagon's available narrow whitewall choices create a different visual character. For a restoration where exact originality matters, size should remain the anchor point and appearance details should be checked against marque references, period photography, or other vehicle-specific historical documentation.
How does tire construction affect the appearance of a restored 1975 Peugeot 504?
On the 1975 Peugeot 504, primary fitment stays within radial construction across both listed sizes, so appearance differences come more from sidewall treatment and tire series than from a bias-ply-versus-radial decision. Blackwall options present a restrained, European-style look, while the 185R14 wagon fitment also allows a narrow whitewall presentation.
That means restoration-minded buyers can focus on getting the proper size for the sub-model first, then decide how formal or understated they want the finished car to look. A sedan kept on blackwalls will read differently from a wagon wearing narrow whitewalls, even though both can remain within correct vintage-style fitment boundaries.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Peugeot 504?
Yes, modifications can affect tire fitment on a 1975 Peugeot 504 even when the tire size itself is correct for the sub-model. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or body repairs can all influence how a 175R14 or 185R14 tire sits and clears the car.
A modified 504 should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before tires are selected or installed. The sedan-versus-wagon size split still matters, but any departure from the stock-style setup can change the amount of available room and the range of tire products that make sense.
What should I inspect before driving a 1975 Peugeot 504 on new tires?
Before driving a 1975 Peugeot 504 on new tires, inspect the wheels, valve stems, and overall wheel condition, then confirm that the car has the correct tire size for its sedan or wagon configuration. It is also wise to check alignment condition, brake operation, and whether the tires clear the body and suspension through the full steering range.
Collector-era cars often spend long periods parked, so attention should also go to worn suspension bushings, weak shocks, or wheel-bearing play that can affect how fresh tires perform. Proper inflation, careful initial road testing, and a quick recheck for rubbing or air loss help confirm that the car is ready for regular use.
How should 175R14 and 185R14 tires on a collector 1975 Peugeot 504 be maintained?
Tires on a collector 1975 Peugeot 504 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Both 175R14 and 185R14 radials benefit from being kept clean, protected from prolonged sunlight and ozone sources, and inspected for cracking, bulges, cuts, uneven wear, or slow air loss.
Low-mileage cars can age tires out before they wear them out, so condition matters as much as tread depth. A Peugeot 504 that sees occasional use should have its tires inspected before longer drives, and any sign of sidewall deterioration or recurring pressure loss should be addressed before the car returns to road service.
