1979 Peugeot 504 Tires

A 1979 Peugeot 504 uses either 175R14 or 185R14, depending on the sub-model. Sedan (Diesel) and Sedan (Gas) models use 175R14, while Wagon (Diesel) and Wagon (Gas) models use 185R14. Both are radial tire fitments built for 14-inch wheels.

The important step is confirming whether the car is a sedan or a wagon before choosing a tire. Since both sizes share the same wheel diameter, the difference is not the rim size but the tire size itself. If the car has replacement wheels or prior modifications, check the actual wheel width and the space around the fenders and suspension before selecting a specific product.

The 1979 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 vehicle stays within one rim diameter across the covered sub-models.

That makes wheel diameter easier to confirm, but it does not mean every 14-inch wheel is equally suitable. Tire products in these sizes can carry different recommended rim-width ranges, so the actual wheel width still matters. A car with aftermarket wheels should be measured carefully before mounting tires, especially when moving between brands or comparing blackwall and whitewall options.

The 1979 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 radial sizes for 14-inch wheels, but the body style determines which of the two primary sizes belongs on the car.

That means tire selection starts with the exact version of the vehicle rather than with brand or sidewall style. A wagon should be matched to 185R14 choices, while a sedan should be matched to 175R14 choices. If the car has had wheel changes over the years, verify the wheel width and overall clearance so the selected tire suits the actual setup now on the car.

For a 1979 Peugeot 504 sedan, the first consideration is staying with the correct 175R14 radial size. From there, the main choices are brand, tire series, sidewall appearance, and wheel-width compatibility. Michelin and Vredestein options are available in this size, including Michelin XAS, Sprint Plus, and Sprint Classic.

A buyer deciding among 175R14 tires should think about how the car will be used and how authentic or understated the finished look should be. Blackwall tires keep the presentation simple and period-appropriate for many restorations and drivers. It also helps to compare the wheel's actual width against the tire's fitment range so the selected tire suits the car beyond size code alone.

Sidewall style depends on the tire size used on the 1979 Peugeot 504. In 175R14, the available choices are blackwall. In 185R14, both blackwall and narrow whitewall options are available, giving wagon owners more visible appearance variation within the correct primary size.

That makes sidewall selection partly a sub-model question and partly an appearance decision. A blackwall tire usually gives the car a clean European presentation, while a narrow whitewall can shift the look in a more formal or vintage direction. Appearance should be chosen after confirming the correct tire size for the car, since sidewall style does not override basic fitment requirements.

Michelin, Vredestein, and Phoenix offer applicable tires for the 1979 Peugeot 504, depending on the size. The 175R14 sedan fitment is available from Michelin and Vredestein, while the 185R14 wagon fitment includes Michelin, Vredestein, and Phoenix options.

Brand choice is only one part of the decision. It helps to compare the tire series offered within the correct size, along with sidewall style and wheel-width suitability where that information is available. A careful selection keeps the car in the right fitment while letting the owner choose between a more understated blackwall presentation and, on some 185R14 products, a narrow whitewall look.

A period-style 1979 Peugeot 504 starts with using the proper sub-model size: 175R14 for sedans and 185R14 for wagons. Both are Euro-metric radial fitments that suit the car's late-1970s European character. From there, period-style choices can include blackwall tires from Michelin or Vredestein, and some 185R14 wagon options also add a narrow whitewall presentation.

The right appearance depends on whether the goal is an understated driver, a restoration-oriented wagon, or a car that closely reflects period road-going style. Tire series and sidewall treatment change the visual impression even within the same size. If exact originality matters, compare the final choice against marque references, period photos, or other vehicle-specific historical material before making the decision.

Correct tire fitment matters on a 1979 Peugeot 504 restoration because the car uses two different primary sizes depending on body style. A sedan restored on 175R14 and a wagon restored on 185R14 will keep the proper visual relationship between tire and body, while also staying within the intended 14-inch radial format.

Fitment also influences the overall stance and the way the finished car presents itself. Even when several brands or sidewall styles are available, the restoration should begin with the correct size for the exact sub-model. Wheel width deserves attention as well, especially on a car that may have picked up replacement wheels over decades of use, storage, or prior refurbishment.

Modifications can affect tire fitment on a 1979 Peugeot 504 even when the tire size itself is correct. Aftermarket wheels, suspension changes, altered ride height, or body repairs can all change how a 175R14 or 185R14 tire sits in the wheel opening and how much room it has during steering and suspension movement.

A car that no longer has its original wheels should have both wheel diameter and wheel width checked before new tires are mounted. Clearance around the fenders, inner wheel housings, and steering components also deserves attention. The same sub-model size remains the starting point, but any Peugeot that has been modified should be verified as it exists today rather than assumed to match stock dimensions.

Before driving a 1979 Peugeot 504 on new tires, inspect the wheels for correct diameter and condition, confirm the tire size matches the sub-model, and check that the tires are properly seated and inflated. It is also wise to look over suspension and steering components so the new tires are not being asked to work with worn hardware.

A collector-era car should also be checked for fender and steering clearance at full lock, especially if replacement wheels are already on the car. After the first drives, recheck air pressure and look for any signs of rubbing or uneven contact. That early inspection helps catch fitment issues quickly and gives the new tires a better chance to wear evenly from the start.

Tires on a collector 1979 Peugeot 504 should be maintained with regular pressure checks, visual inspection, and careful storage habits. Even a lightly driven sedan or wagon can develop problems from age, underinflation, prolonged sitting, or exposure to heat and sunlight. Sidewall cracking, bulges, cuts, and slow air loss deserve attention before the car is driven.

Mileage alone does not tell the whole story on a vintage Peugeot. Cars that spend long periods parked should have their tires inspected more often and moved occasionally to avoid prolonged flat spotting. Clean, dry storage away from direct sun and ozone sources helps preserve the tires, and any uncertainty about age or condition should be addressed before extended road use.
