The 1955 Peugeot 203 sits in the postwar European small-car tradition, known for practical engineering, clean aerodynamic lines, and the kind of everyday durability that helped French cars build a loyal following. That character matters when choosing tires, because this model family uses radial construction throughout, but not every 203 sub-model uses the same size. Depending on the version, fitment centers on 155-400, 155R15, 175-400, or 185-400. For buyers working with the 155R15 setup, available choices include several blackwall radial series from Firestone, Michelin, Avon, and Vredestein. The key is matching the exact sub-model first, then confirming wheel dimensions and the kind of road use or restoration presentation desired.
Which Tire Size Is Right for The 1955 Peugeot 203
The 1955 Peugeot 203 uses four primary tire sizes, and the correct one depends on the exact sub-model. Although the covered fitments are all radial, the size format changes between millimetric and inch-rim radial sizing, so the first step is identifying the specific 203 version and confirming whether the car is set up for a 400 mm fitment or a 15-inch wheel.
155-400 is a millimetric radial size, with 155 referring to nominal section width in millimeters and 400 referring to the wheel diameter in millimeters rather than inches. This is a radial fitment, which suits the Peugeot 203's postwar European design and its use of early modern tire construction. Its main importance is fitment accuracy, because a 400 mm tire setup should not be confused with a 15-inch wheel arrangement. Buyers considering this size should confirm the actual wheel on the car before choosing a replacement, especially if the vehicle has changed hands or seen past wheel swaps.
155R15 is a Euro-metric radial size, with 155 indicating nominal section width in millimeters, R marking radial construction, and 15 identifying the rim diameter in inches. On the 1955 Peugeot 203, this size opens the broadest visible product choice, with blackwall offerings from Firestone, Michelin, Avon, and Vredestein across series such as F560 Radial, Michelin X, XAS, XAS-FF, CR6ZZ, Snow Classic, and Sprint Classic. That makes it the size where appearance, series character, rim-width compatibility, and intended driving use become especially important parts of the decision.
185-400 is a millimetric radial size, using a nominal 185 millimeter section width on a 400 mm wheel. As a radial fitment, it reflects the European sizing conventions that can appear unfamiliar next to modern inch-based tire designations, even though it remains a purpose-specific vintage fitment. On the 1955 Peugeot 203, this size applies to selected sub-models rather than the full range, so it should be matched carefully to the exact vehicle configuration. The practical issue is making sure the car still carries the correct wheel standard before any tire is chosen.
175-400 is another millimetric radial size, pairing a nominal 175 millimeter section width with a 400 mm wheel diameter. For a 1955 Peugeot 203, that means working within a vintage European sizing system where the wheel measurement is metric, so it needs to be distinguished clearly from 15-inch fitments. This size belongs to specific sub-model coverage and should not be treated as universal across all 203 variants. It is best evaluated by confirming the exact sub-model and wheel setup first, then checking overall condition and clearance on a car that may have seen decades of maintenance or modification.
Tire fitment varies across the 1955 Peugeot 203 range, so the exact sub-model matters before any size decision is made. Some versions use millimetric 400 mm radial sizing, while the 203 C uses a 15-inch radial fitment that brings a much broader product selection.

1955 Peugeot 203 Base
The 1955 Peugeot 203 Base uses the 155-400 radial size. That makes wheel-standard confirmation especially important, since this is a millimetric fitment and should be matched to the car's actual wheel setup before choosing a replacement tire.
The 1955 Peugeot 203 C uses 155R15 radial tires on a 15-inch rim. This version gives the clearest product choice, with several blackwall radial series available, so the decision can center more on tire character, rim-width compatibility, and intended use.
The 1955 Peugeot 203 L & CL uses the 185-400 radial size. Tire selection starts with preserving that specific millimetric fitment, then checking that the wheels and overall setup still match the original-style configuration carried by the vehicle.
The 1955 Peugeot 203 U6 & C5 also uses the 185-400 radial size. For this sub-model grouping, the practical focus is confirming the 400 mm wheel arrangement and avoiding confusion with 15-inch radial sizing before moving to product selection.
The 1955 Peugeot 203 U8 & C8 uses the 175-400 radial size. That places fitment accuracy ahead of style choice, since the buyer should verify the wheel standard and current vehicle setup before selecting any replacement tire.
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.

These 1955 Peugeot 203 tire FAQs focus on the most important fitment questions: which size belongs to each sub-model, how 400 mm and 15-inch setups differ, and what to compare when choosing among available radial options.
Tire Size & Fitment
What tire size fits a 1955 Peugeot 203?
A 1955 Peugeot 203 can use one of four primary tire sizes: 155-400, 155R15, 175-400, or 185-400. The correct size depends on the exact sub-model, not just the model name alone, and all of these fitments are radial rather than bias-ply.
The main point is to identify the specific 203 version before selecting a tire. A 400 mm wheel setup and a 15-inch wheel setup are not the same thing, even when the section width looks close, so the wheel standard on the car should be confirmed before replacement.
What size rim does a 1955 Peugeot 203 use?
The 1955 Peugeot 203 range includes fitments tied to both 400 mm sizing and a 15-inch rim size. The 155R15 setup uses a 15-inch rim, while the 155-400, 175-400, and 185-400 sizes are millimetric radial fitments that should be matched to their corresponding wheel standard.
That distinction matters because 400 mm and 15-inch are close enough to create confusion but should not be treated as interchangeable. A buyer should inspect the wheels actually installed on the vehicle, especially on a collector car that may have had wheels or tires changed at some point.
Do all 1955 Peugeot 203 sub-models use the same tire size?
No. The 1955 Peugeot 203 Base uses 155-400, the 203 C uses 155R15, the 203 L & CL and U6 & C5 use 185-400, and the U8 & C8 uses 175-400. The fitment stays radial throughout the range, but the size differs by sub-model.
That means a tire chosen for one 203 variant should not be assumed correct for another. Matching the sub-model first helps avoid ordering the wrong wheel standard or section width, and it is especially useful when the car's badges, papers, and current wheels do not all tell the same story.
Choosing the Right Tire
What should I consider when choosing a 155R15 tire for a 1955 Peugeot 203?
Start with the exact fitment, since 155R15 applies to the 1955 Peugeot 203 C rather than the full 203 range. After that, compare radial series, rim-width suitability, sidewall presentation, and any load figures that matter for how the car will be used.
The available 155R15 choices are all blackwall radials, but they differ by brand and series, including Firestone, Michelin, Avon, and Vredestein. That gives room to choose between a more traditional touring presentation and a more specialized period-style radial, while still keeping the correct overall size format for the car.
What brands offer tires for the 1955 Peugeot 203?
For the 155R15 fitment used on the 1955 Peugeot 203 C, available brands include Firestone, Michelin, Avon, and Vredestein. Those options cover several radial series rather than just one uniform tire, so brand choice is really part of a broader comparison of size-correct products.
The useful next step is comparing the specific series within those brands, such as Michelin X, XAS, XAS-FF, Firestone F560 Radial, Avon CR6ZZ, and Vredestein Sprint Classic or Snow Classic. Buyers should keep the focus on fitment, wheel compatibility, and intended use rather than treating brand alone as the deciding factor.
What tire series are available for the 1955 Peugeot 203?
The 155R15 fitment for the 1955 Peugeot 203 C is available in several tire series, including Firestone F560 Radial, Michelin X, Michelin XAS, Michelin XAS-FF, Avon CR6ZZ, Vredestein Snow Classic, and Vredestein Sprint Classic. All of them are radial tires in a blackwall presentation.
Series matters because it helps separate one size-correct tire from another when the vehicle itself uses only one fitment in that sub-model. Looking at rim-width range, load specification where stated, and the kind of driving planned for the car will usually do more to narrow the choice than the size marking alone.
Restoration & Appearance
Which tire should I choose for a period-style 1955 Peugeot 203?
A period-style 1955 Peugeot 203 should start with the correct primary tire size for the exact sub-model, whether that is 155-400, 155R15, 175-400, or 185-400. Since the 203 uses radial fitments across this range, keeping the proper size format and wheel standard is the foundation of an authentic-looking result.
For a 155R15-equipped 203 C, the available blackwall radial series offer different ways to maintain a traditional presentation without stepping outside the correct size family. Buyers pursuing exact historical originality should still compare tire appearance against marque references and vehicle-specific documentation before settling on one series.
Does correct tire fitment matter for a 1955 Peugeot 203 restoration?
Yes, correct tire fitment matters on a 1955 Peugeot 203 restoration because the car's sub-models do not all use the same tire size or the same wheel standard. A restoration that confuses 400 mm millimetric sizing with 15-inch fitment can look wrong and create avoidable fitment problems.
Proper fitment also affects stance, wheel compatibility, and how convincingly the car presents as a coherent period vehicle. Even when the car is restored more for touring than show judging, matching the correct size family to the correct sub-model is a better starting point than choosing by appearance alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1955 Peugeot 203?
Yes. A 1955 Peugeot 203 with aftermarket wheels, altered suspension height, brake conversions, or body changes can end up with tire-fitment needs that differ from its original sub-model specification. That is especially important here because the 203 range includes both 400 mm and 15-inch radial fitments.
Any modified car should have its current wheel diameter and width checked before replacement tires are chosen. Steering clearance, fender clearance, and overall setup deserve a careful look as well, since a vintage Peugeot may have accumulated changes over time that are not obvious from badges or paperwork alone.
What should I inspect before driving a 1955 Peugeot 203 on new tires?
Before driving a 1955 Peugeot 203 on new tires, inspect the wheels for correct diameter, visible damage, and proper bead-seat condition, then confirm that the tire size matches the exact sub-model. It also helps to check valve stems, lug hardware, and basic suspension and steering condition before road use.
Once the tires are mounted, look for even clearance through steering travel and suspension movement, then set and monitor inflation carefully. A collector car that has spent long periods parked should also be checked for brake drag, alignment issues, and any old chassis wear that might affect how the new tires behave.
How should 1955 Peugeot 203 tires be maintained?
Tires on a 1955 Peugeot 203 should be maintained with regular pressure checks, visual inspection of tread and sidewalls, and routine monitoring for cracking, bulges, cuts, or slow air loss. Vintage cars that see limited mileage still need attention because age and storage conditions can matter as much as road wear.
Keeping the car away from prolonged heat, sunlight, moisture, and ozone sources helps preserve the tires between drives. It is also wise to inspect them before any longer outing, since a Peugeot 203 that sits for extended periods may develop flat spotting or reveal wheel and suspension issues only when returned to service.
