The 1959 Peugeot 203 represents the practical, intelligently engineered side of postwar French motoring, with light handling and road manners that helped make the model widely respected well beyond its home market. Tire selection for this car is more configuration-specific than it first appears, because the 1959 Peugeot 203 can use 155-400, 155R15, or 185-400 depending on the exact sub-model. All three are radial fitments, but they are not the same sizing system. For owners, the key decision is confirming the sub-model first, then choosing a tire that suits restoration priorities, wheel compatibility, and the way the car will actually be driven.
Which Tire Size Is Right for The 1959 Peugeot 203
The 1959 Peugeot 203 uses three different tire sizes, and the correct one depends on the specific sub-model. Although all of the fitments are radial, they appear in different sizing systems, including millimetric and Euro-metric formats. The first step is identifying whether the car is a Base, C, or U6 & C5, then confirming the wheel setup before choosing among the available tire options in the proper size.
155-400 is a millimetric radial size, with 155 representing nominal section width in millimeters and 400 indicating a metric wheel-seat diameter rather than a simple inch-based rim callout. For the 1959 Peugeot 203, this size belongs to the radial era of European fitment and should be treated as a distinct specification, not as shorthand for a 15-inch replacement. Tire choice in this size centers more on preserving the correct fitment format than on comparing a wide range of sidewall or series variations. It is a size that rewards careful wheel verification before any replacement decision is made.
155R15 is a Euro-metric radial size in which 155 is the nominal section width in millimeters, R identifies radial construction, and 15 is the rim diameter in inches. On the 1959 Peugeot 203, this fitment opens the broadest range of product choice, with blackwall options from Firestone, Michelin, Avon, and Vredestein across several radial series. That makes the decision less about finding any tire in the size and more about matching the tire's character to the car's intended use. Rim-width compatibility is also worth checking when comparing one 155R15 product to another.
185-400 is another millimetric radial size, but with a wider nominal section width than 155-400. The 400 designation refers to a metric wheel-seat diameter, so this size should not be treated casually as an inch-based alternative even though the vehicle summary groups the fitments around a 15-inch rim family. For the 1959 Peugeot 203, this size serves a specific sub-model application rather than the full model line. Choosing it correctly means confirming the exact version of the car and making sure the wheel and tire format remain compatible with the original setup.
Sub-model fitment matters on the 1959 Peugeot 203 because the covered versions do not all use the same tire size. A Base, C, and U6 & C5 can each point to a different radial fitment, so identifying the exact sub-model is the first step before comparing tires or wheels.

1959 Peugeot 203 Base
The 1959 Peugeot 203 Base uses the 155-400 radial size, which places it in a millimetric European fitment format rather than a conventional modern inch-marked size. Tire selection for this version starts with preserving that correct size system and confirming that the wheel setup still matches the car.
The 1959 Peugeot 203 C uses 155R15 radial tires, giving it the most straightforward access to currently available replacement choices in this group. That makes product selection more about comparing radial series, brand character, and rim-width suitability than sorting through multiple primary sizes.
The 1959 Peugeot 203 U6 & C5 uses the wider 185-400 radial size, which is a distinct millimetric fitment tied to this specific version. Owners should treat that as a configuration-specific requirement and verify the wheel format carefully before considering any substitute size or construction.
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 1959 Peugeot 203?
A 1959 Peugeot 203 can use 155-400, 155R15, or 185-400, depending on the exact sub-model. The Base uses 155-400, the C uses 155R15, and the U6 & C5 uses 185-400. All of these are radial fitments, but they are not the same size expressed three different ways.
The practical issue is identifying the exact version of the car before choosing a tire. Millimetric 400-series sizes and inch-based 15-inch radial sizes should not be assumed interchangeable, so the wheel setup on the car deserves a close check before any replacement is selected.
What size rim does a 1959 Peugeot 203 use?
The 1959 Peugeot 203 is associated with a 15-inch rim family, and the 155R15 fitment uses a 15.0-inch rim diameter. Product offerings in 155R15 are built for 15-inch rims, with several examples covering narrow vintage wheel widths in the 4.00 to 5.50 inch range.
That does not mean every 1959 Peugeot 203 wheel should be treated the same without inspection. A car that uses a 400-series millimetric tire needs the correct wheel-seat format, so measuring the existing wheel and confirming whether it is inch-based or millimetric is an important first step.
Do all 1959 Peugeot 203 sub-models use the same tire size?
No. The 1959 Peugeot 203 has sub-model-specific fitment, with the Base using 155-400, the C using 155R15, and the U6 & C5 using 185-400. Each of those is a radial tire size, but the dimensions and sizing conventions differ enough that they should be treated as separate applications.
That variation matters because tire selection starts with the exact sub-model, not just the model name on the title or badge. It is also wise to confirm that the car still has the proper wheels, since decades of repairs or modifications can leave an older Peugeot wearing a different setup.
Choosing the Right Tire
What should I consider when choosing a 155R15 tire for a 1959 Peugeot 203?
Start with the fact that 155R15 applies to the 1959 Peugeot 203 C. Within that size, choices include blackwall radial offerings from Firestone, Michelin, Avon, and Vredestein, with series such as F560 Radial, Michelin X, XAS, XAS-FF, CR6ZZ, Snow Classic, and Sprint Classic.
The next comparison points are rim-width compatibility, tire series character, and any stated load figure or speed designation that matches the car's intended use. A restoration-minded owner may prioritize a traditional look, while a driver-focused owner may concentrate more on the specific radial design and wheel match.
What brands offer tires for the 1959 Peugeot 203?
For the 155R15 fitment used on the 1959 Peugeot 203 C, available brands include Firestone, Michelin, Avon, and Vredestein. Those brands cover several distinct radial series rather than one generic replacement, so the choice is broader than simply finding the correct size stamped on the sidewall.
Brand selection is best handled as part of the overall tire decision, not as a shortcut by itself. Once the correct sub-model and size are confirmed, compare the series offered by each brand, check wheel-width suitability, and think about whether the car will be used mainly for display, casual driving, or longer road miles.
What tire series are available for the 1959 Peugeot 203?
In 155R15 for the 1959 Peugeot 203 C, available tire series include Firestone F560 Radial, Michelin X, Michelin XAS, Michelin XAS-FF, Avon CR6ZZ, Vredestein Snow Classic, and Vredestein Sprint Classic. All are blackwall radials, but they are not identical in series design or wheel-width range.
That variety gives owners room to match the tire to the car's purpose. Some buyers will focus on a traditional European presentation, while others may care more about a particular radial series and the wheel dimensions it accommodates, especially if the car has replacement rims or sees regular road use.
Restoration & Appearance
Which tire should I choose for a period-style 1959 Peugeot 203?
A period-style choice starts with using the tire size that belongs to the exact 1959 Peugeot 203 sub-model. On a Base, that means 155-400; on a C, 155R15; and on a U6 & C5, 185-400. Keeping the proper size format preserves the car's intended stance and avoids mixing millimetric and inch-based fitments casually.
For a 155R15-equipped car, blackwall radial choices from several established brands give a traditional look without drifting into modern visual themes. If exact originality matters beyond general period style, the next step is comparing the car against marque literature, photos, and restoration references for that specific configuration.
Does correct tire fitment matter for a 1959 Peugeot 203 restoration?
Yes, correct tire fitment has a major effect on a 1959 Peugeot 203 restoration because the car's sub-models use different radial sizes and even different sizing systems. A 155-400, 155R15, and 185-400 do not represent the same visual or mechanical fitment, even though they may appear similar at a glance.
Getting the fitment right helps preserve the car's proportions, wheel compatibility, and overall presentation. It also reduces the risk of building a restoration around the wrong wheel format, which can create unnecessary complications later when matching tire size, clearance, and intended road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1959 Peugeot 203?
Yes. A 1959 Peugeot 203 with replacement wheels, altered suspension height, or body repairs may no longer match its original tire and wheel setup exactly. That matters even more here because the model range includes both 400-series millimetric radial sizes and a 155R15 inch-based radial fitment depending on sub-model.
Checking the actual wheel diameter, wheel-seat type, and width on the car is a smart first move before ordering any tire. Steering clearance, fender room, and the car's current ride height should also be reviewed so the selected size works with the Peugeot's present configuration.
What should I inspect before driving a 1959 Peugeot 203 on new tires?
Inspect the wheels for damage, verify that the wheel format matches the intended tire size, and make sure the tires are mounted in the correct size for the exact 1959 Peugeot 203 sub-model. It also makes sense to look over valve stems, balancing, and general clearance at the fenders and steering components.
A short test drive should be paired with a follow-up check for air loss, rubbing, vibration, or unusual wear. On an older car, suspension bushings, steering parts, and alignment condition can influence how new tires behave, so road readiness is about more than fresh rubber alone.
How should tires on a collector 1959 Peugeot 203 be maintained?
Tires on a collector 1959 Peugeot 203 should be kept at the appropriate operating pressure for the tire being used, inspected regularly for cracking, cuts, bulges, and uneven wear, and checked for air loss even when the car is driven only occasionally. Low-use collector cars can age tires long before they wear them out.
Storage conditions also matter. Keeping the Peugeot away from prolonged sunlight, heat, moisture, and ozone sources helps protect sidewalls and overall tire condition. Periodic movement, clean wheels, and routine visual inspections make it easier to catch problems before a casual weekend drive turns into a roadside issue.
