The 1973 Peugeot 504 stands out as one of the era’s most respected French family cars, known for its composed road manners, long-distance comfort, and understated engineering character. That makes tire selection especially important, because the way a 504 rides and steers is closely tied to keeping the right tall-profile radial fitment. Sedan models use 175R14, while Wagon models use 185R14, and both sizes stay within the traditional Euro-metric radial theme that suits the car’s period design. Available choices include blackwall and narrow whitewall styles from Michelin, Vredestein, and Phoenix. The real decision is matching the correct sub-model size, then choosing the look and product character that best fits restoration goals and road use.
Which Tire Size Is Right for The 1973 Peugeot 504
The 1973 Peugeot 504 uses two primary tire sizes, and the right one depends on the body style. Both sizes are radial tires for 14-inch rims, but Sedan and Wagon fitment differs, so identifying the exact sub-model comes first. Once that is settled, the choice moves to brand, sidewall appearance, and the character of the available Euro-metric radial options.
175R14 is a Euro-metric radial size with a 175-millimeter nominal section width, radial construction, and a 14-inch rim diameter. In this format, the aspect ratio is not stated in the size code and is conventionally associated with a tall-profile radial look that suits many period European cars. For the 1973 Peugeot 504, this size is offered in blackwall form through Michelin and Vredestein, including XAS, Sprint Plus, and Sprint Classic lines. It is the key size to evaluate for Sedan applications, especially when preserving the 504’s original-style ride height and traditional visual balance matters.
185R14 is a Euro-metric radial size that uses a 185-millimeter nominal section width on a 14-inch rim. Like other unstated-aspect-ratio metric radials of the period, it carries the tall-profile appearance and road-going character associated with classic European fitments. For the 1973 Peugeot 504, available choices include blackwall and narrow whitewall versions from Michelin, Phoenix, and Vredestein, giving this size more visual variety than a simple one-tire replacement decision. It is the size to focus on for Wagon fitment, where confirming wheel condition and selecting the right appearance both matter.
Sub-model fitment on the 1973 Peugeot 504 is not one-size-fits-all. Sedan and Wagon models use different radial tire sizes, so confirming the exact body style is the first step before comparing brands, sidewall styles, or product details.

1973 Peugeot 504 Sedan (Gas)
The 1973 Peugeot 504 Sedan (Gas) uses a 175R14 radial tire on a 14-inch rim. That keeps selection centered on period-style Euro-metric radial choices in blackwall form, with attention focused on brand character, wheel compatibility, and overall presentation rather than switching between multiple primary sizes.
The 1973 Peugeot 504 Wagon (Gas) uses a 185R14 radial tire on a 14-inch rim. That opens the door to both blackwall and narrow whitewall options, so tire selection becomes a matter of balancing the correct fitment with the appearance and product style that best suits the vehicle.
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.
Best 1973 Peugeot 504 Tires for Sale
Available 1973 Peugeot 504 tire choices center on 175R14 and 185R14 radials from Michelin, Vredestein, and Phoenix. Buyers can compare blackwall and narrow whitewall styles, familiar Michelin and Sprint-series options, and rim-width specifications that vary slightly by product.
Common 1973 Peugeot 504 tire questions usually come down to Sedan versus Wagon sizing, 14-inch rim fitment, Euro-metric radial interpretation, sidewall style choices, and the checks worth making before putting a collector-era Peugeot back on the road.
Tire Size & Fitment
What tire size fits a 1973 Peugeot 504?
A 1973 Peugeot 504 uses one of two radial tire sizes depending on the sub-model. The Sedan (Gas) uses 175R14, while the Wagon (Gas) uses 185R14. Both are classic Euro-metric radial fitments designed for 14-inch wheels, but they are not interchangeable as a universal one-size choice across the entire model range.
The important next step is confirming whether the car is a Sedan or a Wagon before choosing a tire. Once the correct size is identified, compare the available sidewall style, brand, and rim-width specification for the tire being considered, especially if the car has replacement wheels or has been stored for long periods.
What size rim does a 1973 Peugeot 504 use?
The 1973 Peugeot 504 uses a 14-inch rim diameter with both primary tire sizes. The Sedan’s 175R14 and the Wagon’s 185R14 are both built around that same 14-inch wheel diameter, so the difference between the two fitments is tire size rather than a change in wheel diameter.
Rim diameter is only part of the picture, so wheel width still deserves attention when selecting a tire. Product fitments in these sizes show slightly different approved rim-width ranges, which matters if the car has aftermarket wheels, older replacement rims, or anything other than the wheel setup it has historically carried.
Do all 1973 Peugeot 504 sub-models use the same tire size?
No, 1973 Peugeot 504 sub-models do not all use the same tire size. The Sedan (Gas) uses 175R14, while the Wagon (Gas) uses 185R14. Both are radial tires for 14-inch rims, but the Wagon carries a different primary size than the Sedan, so fitment needs to be matched to the specific body style.
That difference matters because the buyer’s real decision starts with identifying the exact sub-model, not simply choosing any Peugeot 504 tire. It also affects which product options are available, since 185R14 includes narrow whitewall choices while 175R14 is centered on blackwall offerings from Michelin and Vredestein.
Choosing the Right Tire
What should I consider when choosing a 175R14 or 185R14 tire for a 1973 Peugeot 504?
Start with the correct sub-model size, since the 1973 Peugeot 504 Sedan uses 175R14 and the Wagon uses 185R14. After that, focus on radial construction, 14-inch rim compatibility, and the visual presentation you want, because these sizes are offered in traditional Euro-metric forms that preserve the car’s period character.
Product differences can include brand, tire series, sidewall style, rim-width range, load figure where stated, and even tire weight. A car kept close to its original appearance may call for one look, while a driver-focused 504 may lead to another, so wheel condition and intended road use should guide the final choice.
What sidewall styles are available for 1973 Peugeot 504 tires?
Sidewall choices for the 1973 Peugeot 504 include blackwall and narrow whitewall, depending on the tire size. The 175R14 selections center on blackwall tires, while 185R14 adds narrow whitewall options alongside blackwall choices. That gives Wagon fitment more visible appearance variation than a simple brand-only decision.
Sidewall style changes the car’s visual tone more than the fitment itself, so it helps to decide whether the goal is a restrained European look or a slightly dressier period presentation. The right choice still needs to stay within the correct Sedan or Wagon tire size, since appearance should follow fitment rather than replace it.
What brands offer tires for the 1973 Peugeot 504?
Michelin, Vredestein, and Phoenix offer tires for the 1973 Peugeot 504 across its two primary radial sizes. Michelin appears in both 175R14 and 185R14 applications, Vredestein offers multiple Sprint-series choices, and Phoenix appears in 185R14 with a narrow whitewall presentation aimed at buyers who want a different period-style look.
Brand alone should not drive the decision. It makes more sense to compare the correct size for the sub-model, then look at sidewall style, tire series, and wheel compatibility details within that size, especially since Sedan and Wagon fitments differ and the available appearance choices are not identical between them.
Restoration & Appearance
Which tire should I choose for a period-style 1973 Peugeot 504?
A period-style 1973 Peugeot 504 starts with keeping the correct body-style fitment: 175R14 for the Sedan and 185R14 for the Wagon. Both are tall-profile Euro-metric radial sizes that suit the 504’s 1970s European character. From there, the decision becomes one of brand, tire series, and whether the car should wear a restrained blackwall or a dressier narrow whitewall.
Restoration-minded buyers usually benefit from treating size and profile as the foundation, then using sidewall style to fine-tune the appearance. When exact originality matters, marque-specific references and period photography can help confirm what look makes the most sense for a particular car before selecting among the available products.
How does tire construction affect the appearance of a restored 1973 Peugeot 504?
Tire construction is straightforward on the 1973 Peugeot 504 because its primary fitments are radial, not bias-ply. That helps preserve the tall, European touring-tire look associated with sizes like 175R14 and 185R14. In visual terms, the bigger appearance choice comes from staying with the proper sub-model size and selecting either blackwall or narrow whitewall where available.
A restored 504 can look noticeably different if the tire profile or sidewall treatment drifts away from the period feel, even when the wheel diameter remains correct. Keeping the proper metric radial fitment generally does more for the car’s stance and character than chasing a dramatic sidewall treatment that does not suit the build.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 Peugeot 504?
Yes, modifications can affect tire fitment on a 1973 Peugeot 504 even when the tire size itself is correct for the Sedan or Wagon. Changes to wheel width, wheel offset, ride height, springs, or suspension components can alter how a 175R14 or 185R14 tire sits in the wheel opening and how much clearance remains during steering and suspension movement.
A modified car should be checked more carefully than one on a stock-style wheel setup. Wheel diameter still needs to remain 14 inches for these primary sizes, but clearance at the fenders, suspension, and steering components matters just as much before committing to a tire for regular road use.
What should I inspect before driving a 1973 Peugeot 504 on new tires?
Before driving a 1973 Peugeot 504 on new tires, inspect the wheels for damage or corrosion, verify that the tire size matches the correct sub-model, and check that the tires seat properly and hold pressure. It also makes sense to look over the valve stems, suspension condition, and basic alignment-related wear points before putting miles on a newly mounted set.
A short road test should confirm that the car tracks cleanly, the steering moves freely, and nothing rubs under normal driving. On a collector-era Peugeot, it is also wise to recheck pressure and fastener security after the first drive, since long storage and infrequent use can expose small issues once the car returns to service.
How should 175R14 and 185R14 tires on a collector 1973 Peugeot 504 be maintained?
Collector-use 175R14 and 185R14 tires on a 1973 Peugeot 504 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Even low-mileage cars need attention because age, sitting time, and environmental exposure can affect tires long before tread wear becomes severe. Sidewalls should be watched for cracking, cuts, bulges, or signs of persistent air loss.
The 504 benefits from occasional movement and inspection rather than long periods of neglect. Storage away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and a car that returns to the road after sitting should have its wheels, tire pressures, and general clearance checked again before any longer drive.
