The 1956 Citroen CV belongs to the postwar European small-car tradition that prioritized light weight, simplicity, and everyday usefulness over excess size or power. Its appeal today comes from that same honest character, which makes tire selection an important part of preserving the car’s feel on the road. This model uses a 125-400 radial, a millimetric radial size that stands apart from more familiar inch-based American sizing. Because the fitment centers on one primary radial size, the key decision is choosing a tire that respects the car’s proportions and wheel requirements. That matters whether the goal is careful preservation, regular local driving, or a tidy restoration-oriented presentation.
Which Tire Size Is Right for The 1956 Citroen CV
The 1956 Citroen CV uses one primary tire size: 125-400, and it is a radial fitment. The same size applies to the covered Base sub-model, so the main decision is not between multiple factory fitments, but between the available tires within that millimetric radial size and making sure the wheel setup still matches the car.
125-400 is a classic metric or millimetric radial size, with the 125 referring to nominal section width in millimeters and the 400 indicating the wheel diameter in millimeters rather than inches. That makes it different from more familiar inch-based vintage American sizes, so the wheel itself has to match this format. For a 1956 Citroen CV, this radial size supports the car’s light-duty, European-style fitment character rather than a wider or more modern-looking alternative. Choosing this size keeps the tire selection centered on proper wheel compatibility, correct overall presentation, and preserving the car’s intended proportions.
Sub-model fitment is straightforward for the 1956 Citroen CV. The covered sub-model uses the same primary tire size, so the main concern is confirming that the car still has the correct millimetric wheel setup before selecting tires.

1956 Citroen CV Base
The 1956 Citroen CV Base uses the same 125-400 radial fitment as the model core. That keeps tire selection focused on staying with the correct millimetric radial size and verifying that the wheels have not been changed to a different diameter or sizing system.
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.
Frequently Asked Questions
Owners shopping for 1956 Citroen CV tires usually need clarity on the 125-400 millimetric size, wheel compatibility, restoration-minded appearance, and the inspections worth making before putting a lightly used collector car back on the road.
Tire Size & Fitment
What tire size fits a 1956 Citroen CV?
The 1956 Citroen CV uses a 125-400 radial tire. That is the primary tire size for this model, and it is a classic metric or millimetric radial rather than a modern inch-based bias-ply or P-metric size.
The practical point is that 125-400 refers to a wheel diameter measured in millimeters, so tire selection starts with confirming the car still has the proper wheels. Many collector cars have seen wheel changes over the years, and a different wheel setup can completely change what tire size is appropriate.
What size rim does a 1956 Citroen CV use?
A 1956 Citroen CV fitted with 125-400 tires uses a 400-millimeter wheel diameter. That dimension is part of the tire size itself, which is why this fitment differs from more familiar 15-inch or 16-inch vintage tire applications.
Wheel confirmation matters before ordering tires because a millimetric rim cannot be treated like a same-looking inch-based wheel. The safest approach is to verify the actual wheel markings and inspect the wheels already on the car, especially if the vehicle has been restored, stored for years, or modified by a previous owner.
Does the 1956 Citroen CV Base use the same tire size?
Yes. The 1956 Citroen CV Base uses the same 125-400 radial tire size as the model core. That makes sub-model fitment simple compared with vehicles that split tire sizes across trim levels or wheel packages.
Even with shared fitment, it is still worth checking the actual wheels on the car before choosing tires. Older collector vehicles are often changed over time, and the right choice depends on the wheel diameter and condition, not just the badge or trim name on the body.
Choosing the Right Tire
What should I consider when choosing a 125-400 tire for a 1956 Citroen CV?
Start with the correct 125-400 size and the fact that it is a radial fitment for the 1956 Citroen CV. Because this is a millimetric tire size, the first priority is matching the tire to the proper wheel diameter rather than assuming a nearby inch-based size will serve the same role.
After size and wheel compatibility, focus on the condition and intended use of the car. A preservation-minded owner may want a tire that keeps a traditional visual balance, while a driver putting the car on the road regularly should also inspect wheel condition, suspension wear, and available clearance before making a final choice.
How do I choose between the available 125-400 tires for a 1956 Citroen CV?
Choosing between 125-400 tires for a 1956 Citroen CV comes down to staying with the correct fitment and selecting a tire that suits the car’s purpose. Since there is one primary size, the decision is less about dimensions and more about wheel compatibility, appearance, and how the car will be used.
A lightly shown car and a regularly driven collector car may call for slightly different priorities, even when the size stays the same. Looking closely at tire construction details, the wheel setup already on the car, and the overall presentation you want will usually narrow the decision faster than treating it like a generic small-car tire purchase.
What rim-fitment details should I compare when choosing 1956 Citroen CV tires?
The most important rim-fitment detail for a 1956 Citroen CV is wheel diameter, because 125-400 uses a 400-millimeter rim rather than an inch-based diameter. That single point has a bigger effect on correct tire choice than many buyers expect when looking at a small vintage European car.
It also helps to inspect the wheel itself for age, damage, and any signs of prior modification. A wheel that has been replaced, widened, or converted can change the tire decision completely, so checking actual wheel markings and overall condition is a smart step before mounting new tires on a collector vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1956 Citroen CV?
For a period-style 1956 Citroen CV, the correct starting point is the original fitment type and size: a 125-400 radial. Keeping the car in its proper millimetric radial format helps preserve the narrow, light-duty proportions that are part of the vehicle’s visual character.
Appearance-focused buyers should avoid treating a modern-looking substitute size as automatically acceptable just because it seems close. On a small postwar French car, tire dimensions have a strong effect on stance and visual balance, so matching the proper size and wheel format is often more important than chasing a more common replacement.
Does correct tire fitment matter for a 1956 Citroen CV restoration?
Yes, correct tire fitment matters a great deal on a 1956 Citroen CV restoration. The car’s small scale means tire size has an outsized effect on how it sits, how the wheels fill the arches, and whether the finished car still looks faithful to its period character.
A 125-400 radial keeps the restoration anchored to the proper fitment format, but exact originality questions can go beyond size alone. When show-level authenticity is important, it helps to compare the car against marque references, period photos, and restoration documentation instead of assuming any tire in a similar visual size will look right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1956 Citroen CV?
Yes. Modifications can affect tire fitment on a 1956 Citroen CV, especially if the car has aftermarket wheels, brake changes, altered ride height, or wheel conversions from the original millimetric setup. Even small changes matter on a compact collector car with a narrow original tire size.
A changed wheel diameter or width can turn a correct 125-400 tire choice into the wrong one for the car as it sits today. Checking wheel markings, steering clearance, fender space, and the condition of suspension components will give a much clearer picture before new tires are mounted.
What should I inspect before driving a 1956 Citroen CV on new tires?
Before driving a 1956 Citroen CV on new tires, inspect the wheels, valve stems, and mounting surfaces, then look closely at the steering and suspension for looseness or worn components. Tire pressure should be set correctly, and the car should be checked for any rubbing or uneven stance once the tires are mounted.
Collector cars often spend long periods parked, so the first road test should be careful and gradual rather than treated like normal daily driving. It also makes sense to check for brake drag, fluid leaks, and any signs that the car has settled unevenly in storage, since those issues can affect how new tires behave.
How should 125-400 tires on a collector 1956 Citroen CV be maintained?
125-400 tires on a collector 1956 Citroen CV should be inspected regularly for cracking, cuts, bulges, flat spotting, and air loss, even if the car is driven only occasionally. Low annual mileage does not stop tires from aging, and long storage periods can hide condition problems until the car is back on the road.
Storage habits make a real difference on a lightly used vintage car. Keeping the CV away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition, and moving the car periodically can reduce stress from sitting in one place for extended periods.
