The 1974 Peugeot 504 sat in a sweet spot for European sedans and wagons, blending durable engineering with the balanced road manners that helped the model earn a loyal following well beyond France. For today’s owner, tire choice is less about converting from an older construction and more about matching the correct radial size to the exact body style. Sedan models use 175R14, while wagon models use 185R14, both on 14-inch rims. That keeps the decision focused on the right size first, then on details such as blackwall or narrow whitewall appearance, tire series, and brand. For a road-driven survivor or a careful restoration, body style and wheel setup deserve a close check before ordering.
Which Tire Size Is Right for The 1974 Peugeot 504
The 1974 Peugeot 504 uses two primary tire sizes, and the difference comes down to sub-model rather than tire construction or rim diameter. Both sizes are radial tires for 14-inch wheels, so the first step is confirming whether the car is a sedan or a wagon. Once that is settled, the real comparison becomes brand, sidewall appearance, tire series, and wheel-width compatibility within the correct size.
175R14 is a Euro-metric radial size in which 175 denotes nominal section width in millimeters, R identifies radial construction, and 14 is the wheel diameter in inches. This size suits the 1974 Peugeot 504 sedan models and reflects the kind of metric radial sizing common on European cars of the period. Available choices include Michelin and Vredestein, with blackwall options in series such as XAS, Sprint Plus, and Sprint Classic. For a sedan owner, this size keeps the search centered on the correct fitment while allowing a choice between more touring-oriented presentation and a restoration-minded period look.
185R14 is also a Euro-metric radial size, with a 185-millimeter nominal section width, radial construction, and a 14-inch rim diameter. On the 1974 Peugeot 504, this size is used by wagon models, making body style the key fitment distinction within the range. Product choices include Michelin, Phoenix, and Vredestein, with both blackwall and narrow whitewall appearances available depending on the tire. For wagon owners, this size opens up a broader appearance choice, but wheel width and overall vehicle setup still deserve verification before settling on one specific tire.
Sub-model fitment matters on the 1974 Peugeot 504 because sedan and wagon versions do not share the same tire size. Diesel and gas variants stay consistent within each body style, so the important first step is confirming whether the vehicle is a sedan or a wagon.

1974 Peugeot 504 Sedan (Diesel)
The 1974 Peugeot 504 Sedan (Diesel) uses the 175R14 radial size on a 14-inch rim. That keeps the selection focused on choosing the right blackwall tire series and confirming wheel width rather than sorting through multiple primary fitments.
The 1974 Peugeot 504 Sedan (Gas) also uses the 175R14 radial size, so tire fitment follows the same path as the diesel sedan. Once the sedan body style is confirmed, the choice comes down to brand, tire series, and whether a more road-use or period-style presentation is the goal.
The 1974 Peugeot 504 Wagon (Diesel) uses the larger 185R14 radial size on a 14-inch wheel. That means wagon owners should stay focused on 185R14-specific choices, including blackwall or narrow whitewall appearance, while checking wheel width before making a final selection.
The 1974 Peugeot 504 Wagon (Gas) shares the 185R14 radial fitment used by the diesel wagon. Tire selection therefore centers on the wagon-size product range, with attention to sidewall style, tire series, and compatibility with the actual wheels on 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 1974 Peugeot 504 Tires for Sale
Available 1974 Peugeot 504 tires center on 175R14 and 185R14 radial fitments from Michelin, Vredestein, and Phoenix. The main points of comparison are blackwall versus narrow whitewall appearance, Michelin XAS and MXV versus Vredestein Sprint series character, and wheel-width compatibility within each size.
Common 1974 Peugeot 504 tire questions usually come down to sedan-versus-wagon sizing, 14-inch rim fitment, available radial choices, sidewall appearance, and what to inspect before putting a collector-era Peugeot back on the road.
Tire Size & Fitment
What tire size fits a 1974 Peugeot 504?
A 1974 Peugeot 504 uses one of two radial tire sizes, depending on body style. Sedan models use 175R14, while wagon models use 185R14. Both are Euro-metric radial sizes for 14-inch wheels, so the difference is not construction type but the exact sub-model.
That makes vehicle identification the first step before comparing brands or sidewall styles. A sedan owner should stay within the 175R14 range, while a wagon owner should focus on 185R14 options. If the car has replacement wheels, it is worth confirming both wheel diameter and wheel width before choosing a specific tire.
What size rim does a 1974 Peugeot 504 use?
Both primary tire sizes for the 1974 Peugeot 504 are built for 14-inch rims. The sedan’s 175R14 and the wagon’s 185R14 share that same rim diameter, which simplifies the search compared with vehicles that changed wheel diameter across trims.
Rim diameter alone does not settle the whole fitment question, because width still matters when comparing individual tires. Some 175R14 and 185R14 products are matched to slightly different wheel-width ranges. That is especially important if the Peugeot no longer has its original wheels or has been fitted with aftermarket rims at some point.
Do all 1974 Peugeot 504 sub-models use the same tire size?
No. The 1974 Peugeot 504 splits tire size by body style rather than by fuel type. Sedan models, including both diesel and gas versions, use 175R14. Wagon models, also in diesel and gas form, use 185R14.
That means a buyer should not assume that any 1974 504 uses the same tire simply because the wheel diameter matches. Once the vehicle is identified as a sedan or wagon, fitment becomes much more straightforward. From there, the decision shifts toward brand, sidewall appearance, and whether the wheel width matches the selected tire.
Choosing the Right Tire
What should I consider when choosing a 1974 Peugeot 504 tire?
Start with the correct primary size for the body style: 175R14 for sedans and 185R14 for wagons. From there, the important selection points are radial tire series, wheel-width compatibility, sidewall appearance, and whether the car is being kept as a road-going driver or given a more restoration-oriented presentation.
A sedan owner may be comparing Michelin XAS with Vredestein Sprint options, while a wagon owner may weigh blackwall against narrow whitewall choices in 185R14. The best approach is to match the tire to the car’s intended use and actual wheel setup, rather than choosing strictly by appearance or brand name alone.
What sidewall styles are available for 1974 Peugeot 504 tires?
The available sidewall styles for 1974 Peugeot 504 tires include blackwall and narrow whitewall, depending on size and product. Blackwall choices appear in both 175R14 and 185R14, while narrow whitewall options are offered in 185R14 for wagon applications.
That gives wagon owners more flexibility if a brighter period-style presentation is part of the goal. Sedan owners remain in a more traditional blackwall range. Sidewall style should be chosen after the correct tire size is confirmed, since appearance options do not override the basic sedan-versus-wagon fitment split on the 504.
What brands offer tires for the 1974 Peugeot 504?
1974 Peugeot 504 tires are available from Michelin, Vredestein, and Phoenix, depending on the tire size. The 175R14 sedan fitment includes Michelin and Vredestein choices, while the 185R14 wagon fitment adds Phoenix alongside Michelin and Vredestein.
Brand is only one part of the decision. The more useful comparison is how each option lines up with the correct size, the sidewall look you want, and the wheel-width requirements of the tire. A careful buyer should compare those fitment details first, then use brand and tire series to narrow the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Peugeot 504?
A period-style 1974 Peugeot 504 should begin with the correct body-style fitment: 175R14 for sedans and 185R14 for wagons. From there, traditional blackwall radials such as Michelin or Vredestein options usually give the most restrained European look, while certain 185R14 wagon choices also introduce a narrow whitewall presentation.
The right pick depends on whether the car is being preserved as a tasteful driver or restored with closer attention to period appearance. Exact originality can vary by market and individual car history, so appearance-minded owners may want to compare surviving photos, manuals, or marque-club guidance before settling on one sidewall style.
How does tire construction affect the appearance of a restored 1974 Peugeot 504?
On a 1974 Peugeot 504, the primary fitments are radial tires, so construction choice does not involve deciding between a visibly older bias-ply look and a modern radial profile. The appearance differences here come more from brand character, tread-era presentation, and sidewall treatment than from switching between basic construction types.
That keeps restoration decisions focused on the correct size and visual style for the body type. A blackwall 175R14 or 185R14 generally preserves a clean European presentation, while a narrow whitewall can change the wagon’s overall look considerably. Wheel condition and stance also influence how authentic the finished tire package appears.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Peugeot 504?
Yes. Even though the 1974 Peugeot 504 uses straightforward 14-inch radial fitments, later wheel changes can alter what works safely and cleanly on the car. A different wheel width, offset, suspension height, or brake conversion can affect how a 175R14 or 185R14 tire sits within the wheel opening.
That is why the actual car should be checked before assuming a stock-size tire will behave the same on a modified setup. Clearance at full steering lock, suspension travel, and the match between the tire and wheel width are all worth confirming, especially on a wagon moving into the wider 185R14 size.
What should I inspect before driving a 1974 Peugeot 504 on new tires?
Before putting a 1974 Peugeot 504 back into regular road use, inspect the wheels for damage or excessive corrosion, confirm the tire size matches the sedan or wagon fitment, and make sure the tires are seated properly and holding pressure. It is also smart to look at valve stems, lug hardware, and visible suspension condition.
A short test drive should include listening for rubbing, checking steering response, and verifying that the car tracks properly. Collector cars that have spent time parked can reveal wheel-bearing, alignment, or brake issues only after new tires are installed, so the tire change is a good moment to review the whole rolling setup.
How should 175R14 and 185R14 tires on a collector 1974 Peugeot 504 be maintained?
Collector-car tires on a 1974 Peugeot 504 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of sun, moisture, and ozone exposure. Low-mileage cars still need tire checks because age and storage conditions matter as much as tread depth.
Routine maintenance also includes watching for slow air loss and moving the car enough to avoid prolonged flat spotting. A Peugeot that alternates between storage and occasional driving benefits from periodic pressure checks and visual inspections before every longer outing. That habit helps catch age-related problems before they become road-use issues.
