The 1953 Citroen W 15 comes from an era when Citroen was known for engineering that often stood apart from more conventional European cars. For owners of a surviving W 15 today, tire choice is less about sorting through multiple factory-style fitments and more about understanding one specialized size correctly. This model uses a 185-400 radial tire, a classic metric millimetric radial format that differs from more familiar inch-based sizing. That makes wheel confirmation especially important, since the 400 measurement refers to the rim standard used with this tire. The right selection comes down to preserving proper fit, maintaining the car’s character, and checking wheel condition before road use.
Which Tire Size Is Right for The 1953 Citroen W 15
The 1953 Citroen W 15 uses one primary tire size: 185-400, and it is a radial fitment. The covered W 15 Six sub-model uses that same size, so the main decision is not which primary size fits, but making sure the car still has the correct 400-millimeter wheels and selecting a tire that suits the vehicle’s intended road use and presentation.
185-400 is a classic metric millimetric radial size. The 185 identifies the nominal section width in millimeters, while the 400 refers to the millimetric rim standard rather than a conventional inch-based wheel diameter. As a radial fitment, it reflects a more modern construction style than many period numeric bias-ply sizes, but it still requires careful attention because the wheel standard is unusual by modern U.S. replacement-tire expectations. For a 1953 Citroen W 15, this size is the key fitment checkpoint, especially if the car has had wheel changes, long-term storage, or restoration work at some point in its life.
Fitment is straightforward for the covered 1953 Citroen W 15 sub-model. The W 15 Six uses the same primary tire size, so the important step is confirming that the car still carries the proper millimetric wheel setup before choosing a replacement tire.

Frequently Asked Questions
These FAQs focus on 1953 Citroen W 15 tire size, 400-millimeter wheel fitment, radial construction, period-style replacement considerations, and the checks that matter before putting a collector-era Citroen back on the road.
Tire Size & Fitment
What tire size fits a 1953 Citroen W 15?
The 1953 Citroen W 15 uses a 185-400 tire size. This is a radial fitment in a classic metric millimetric format, which is different from more familiar inch-based vintage tire sizes and modern P-metric sizing found on later vehicles.
That difference matters because the 400 measurement refers to the wheel standard used with the tire. Before choosing a replacement, confirm that the car still has the proper 400-millimeter wheels, especially if it has been restored, modified, or stored for many years. A correct size match starts with the actual wheel on the car, not just the model name.
What size rim does a 1953 Citroen W 15 use?
A 1953 Citroen W 15 using the 185-400 tire requires a 400-millimeter rim standard rather than a conventional 15-inch or 16-inch wheel. That is one of the most important fitment details on this vehicle because the tire size is built around a millimetric wheel diameter.
Owners should verify the actual wheel before ordering tires, particularly on collector cars that may have seen wheel swaps over the decades. Even when the tire size appears straightforward, a millimetric Citroen setup is not the same as an inch-based rim. Checking the wheel itself helps prevent a mismatch and keeps the tire search focused on the correct fitment.
Does the 1953 Citroen W 15 Six use the same tire size?
Yes. The 1953 Citroen W 15 Six uses the same 185-400 radial tire size as the covered 1953 Citroen W 15 fitment. That means there is no separate primary tire size to sort through for this sub-model within the fitment covered here.
Even with shared sizing, it is still smart to inspect the car’s actual wheel and tire setup before replacement. Older vehicles sometimes carry wheels from another application or have been altered during restoration work. On a specialized millimetric fitment like 185-400, confirming the wheel standard is just as important as recognizing the correct tire size.
Choosing the Right Tire
What should I consider when choosing a 185-400 tire for a 1953 Citroen W 15?
Start with the core fitment requirements: the 1953 Citroen W 15 uses a 185-400 radial tire on a 400-millimeter wheel standard. Because this is a specialized classic metric size, the first priority is making sure the wheel on the car matches that format exactly.
After wheel confirmation, think about how the car will be used and presented. A road-driven collector car may need different priorities than a display-focused restoration, but both depend on proper sizing and good wheel condition. It also helps to inspect suspension, steering clearance, and the age and condition of any existing tires before putting the car back into regular service.
How do I choose between available 185-400 tires for a 1953 Citroen W 15?
The right choice begins with staying within the correct 185-400 fitment for the 1953 Citroen W 15. Since this car does not call for multiple primary sizes here, selection is mainly about choosing a tire that matches the car’s wheel setup and intended use rather than moving between different size families.
A restoration-oriented owner may care most about maintaining a traditional visual presentation, while a driver-focused owner may put more attention on overall road use and vehicle condition. In either case, check wheel integrity, confirm there is no hidden mismatch from past modifications, and evaluate how the car will actually be driven before settling on a replacement tire.
What rim-fitment details matter when choosing 1953 Citroen W 15 tires?
The biggest rim-fitment detail is that a 1953 Citroen W 15 using 185-400 tires relies on a 400-millimeter wheel standard. That makes this fitment different from many classic American and British applications that use inch-designated rim diameters, even when the tire appears similar in overall scale.
Wheel condition matters just as much as wheel diameter on an older vehicle. Before mounting new tires, inspect the rims for corrosion, damage, distortion, or previous repair work, and make sure the wheels match side to side. A specialized size can only perform properly when the wheel itself is correct, sound, and appropriate for continued road use.
Restoration & Appearance
Which tire should I choose for a period-style 1953 Citroen W 15?
For a period-style 1953 Citroen W 15, the starting point is the proper 185-400 radial size. Keeping the correct size and wheel standard preserves the car’s overall stance and helps maintain the specialized fitment character that is part of owning and restoring an older Citroen.
Appearance-focused owners should resist the temptation to substitute a more common size without carefully checking the wheels and the visual effect on the car. When exact historical originality matters, it is worth comparing against marque-club guidance, period photos, or restoration records. Even then, the proper fitment foundation remains the correct 185-400 millimetric setup.
Does correct tire fitment matter for a 1953 Citroen W 15 restoration?
Yes, correct tire fitment matters a great deal on a 1953 Citroen W 15 restoration because the car uses a specialized 185-400 radial size. On a vehicle with an uncommon millimetric wheel standard, the wrong tire choice can affect both appearance and the basic compatibility between tire and rim.
Beyond looks, fitment influences how naturally the finished car presents and whether the wheel-and-tire package remains true to the vehicle’s intended setup. Restoration work is also the moment when hidden substitutions often surface, so it is smart to inspect every wheel closely. Getting the fitment right early helps avoid rework and preserves the car’s character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1953 Citroen W 15?
Yes. Modifications can affect tire fitment on a 1953 Citroen W 15, especially if the car has received replacement wheels, brake changes, suspension work, or body alterations over the years. Since this model uses a 185-400 millimetric radial setup, any deviation from the original wheel standard deserves careful attention.
A modified car should be checked for wheel diameter, wheel condition, steering travel, and clearance at the fenders and suspension before new tires are installed. Even modest changes can complicate fitment on an older specialized application. That is why the actual hardware on the car matters more than assumptions based only on year, make, and model.
What should I inspect before driving a 1953 Citroen W 15 on new tires?
Before driving a 1953 Citroen W 15 on new tires, inspect the wheels, lug hardware, valve stems, and the general condition of the suspension and steering components. On a collector-era car, it is also wise to look for fluid leaks, worn bushings, brake issues, and anything that could affect straight tracking or consistent tire contact.
The existing tires should be checked too, even if they are being replaced, because uneven wear can reveal alignment or mechanical issues that will quickly affect the new set. Once the correct 185-400 tires are mounted, verify inflation, watch for any air loss, and take the first road miles cautiously while listening for rubbing, vibration, or pull.
How should 185-400 tires on a collector 1953 Citroen W 15 be maintained?
185-400 tires on a collector 1953 Citroen W 15 should be maintained with regular visual inspection, proper inflation, and careful storage habits. Because many collector vehicles are driven infrequently, tire condition can decline from age, sunlight, moisture, and long stationary periods even when tread wear remains minimal.
Look for cracking, bulges, cuts, flat spotting, and signs of air loss, and inspect the wheels at the same time. Moving the car periodically and storing it away from prolonged heat and ozone sources can help preserve the tires between drives. A short pre-drive inspection is especially worthwhile on a seldom-used Citroen with specialized millimetric fitment.
