The 1961 Citroen DS stood apart from almost every other sedan of its time, combining advanced French engineering with a shape and road presence that still feel unmistakably distinctive. Owners value it not just for style, but for the way every mechanical choice contributes to the car’s character. Tire selection follows that same logic, because this DS uses a 165-400 radial in a millimetric format rather than a more familiar inch-based American size. That makes fitment the first priority, not guesswork. Once the correct size is confirmed, the focus shifts to maintaining the DS’s intended stance, ride character, and overall presentation for restoration or regular road use.
Which Tire Size Is Right for The 1961 Citroen DS
The 1961 Citroen DS uses one primary tire size: 165-400 radial. This fitment appears on the DS 19 Sedan, so the main decision is not between multiple primary sizes, but making sure the car still has the correct millimetric wheel setup and then choosing a tire that suits the car’s appearance and intended use.
165-400 is a classic metric radial size that uses a 165-millimeter nominal section width and a 400-millimeter rim diameter, which is very different from common inch-based rim sizing. Its radial construction is central to the way a 1961 Citroen DS is meant to sit and drive, so this is a fitment where matching the proper wheel format matters as much as choosing the tire itself. Buyers often encounter this size while restoring original-style wheel setups or bringing long-stored cars back into service. The practical step is confirming that the car still wears the correct 400-millimeter wheels before selecting a replacement tire.
Fitment is straightforward for the covered 1961 Citroen DS sub-models, because the same primary tire size is used across them here. Checking the exact sub-model still helps confirm that the car remains on its intended wheel and tire configuration before replacement.

Frequently Asked Questions
Common questions for the 1961 Citroen DS usually center on the 165-400 millimetric tire size, wheel fitment, restoration-minded tire choice, and the checks worth making before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1961 Citroen DS?
The 1961 Citroen DS uses a 165-400 radial tire. That size is a classic metric or millimetric radial fitment, and it is the primary tire size associated with the covered DS application, including the DS 19 Sedan.
The important point is that 165-400 is not a typical inch-based size. Before buying tires, confirm that the car still has the correct 400-millimeter wheels and has not been converted to another wheel format over the years. That check matters more than appearance alone, especially on a restoration or a long-owned collector car.
What size rim does a 1961 Citroen DS use?
A 1961 Citroen DS using the 165-400 tire requires a 400-millimeter rim diameter. That millimetric dimension is built into the tire size itself, so the wheel diameter is part of the fitment rather than a separate inch-based interpretation.
This is one of the first things to verify on the car because a 400-millimeter wheel is not the same as a 15-inch or 16-inch rim. If the car has replacement wheels, a past conversion, or mixed parts from an earlier restoration, confirm the actual wheel setup before selecting tires to avoid an expensive mismatch.
What does 165-400 mean on a 1961 Citroen DS?
On a 1961 Citroen DS, 165-400 refers to a metric radial tire size with a nominal section width of 165 millimeters and a rim diameter of 400 millimeters. It is a period European sizing format rather than the numeric or alphanumeric inch-based sizes more familiar on many American classics.
That distinction matters because the size tells you both the tire’s width class and the wheel format it belongs on. A buyer looking at a DS should treat the 400-millimeter rim requirement as essential, then confirm the car’s current wheels, tire age, and overall setup before replacing tires for road use or restoration display.
Choosing the Right Tire
What should I consider when choosing a 165-400 tire for a 1961 Citroen DS?
Start with the exact size and construction: a 1961 Citroen DS uses a 165-400 radial. On this car, getting the proper millimetric fitment is the first concern, because the wheel format is unusual compared with more common inch-based classic car tire applications.
After confirming the wheel setup, think about how the car will be used. A restoration-minded owner may focus on preserving the proper overall presentation, while a driver may put more emphasis on tire condition and dependable road manners. In either case, inspect the wheels carefully and avoid assuming that a tire with a similar width but different sizing system belongs on the car.
How do I choose between the available 165-400 tires for a 1961 Citroen DS?
Choosing among 165-400 tires for a 1961 Citroen DS begins with the same foundation: correct size, radial construction, and proper fit on the car’s 400-millimeter wheels. Once those points are settled, the differences that matter most are usually condition, intended use, and how closely the tire suits the car’s restoration goals.
A DS that sees occasional show use may call for a more appearance-focused approach, while a car driven regularly benefits from careful attention to age, wear, and general service readiness. It also helps to inspect the wheels for corrosion, previous repairs, or damage, since an otherwise correct tire can only perform properly on a sound wheel.
Why is exact wheel confirmation so important when choosing 1961 Citroen DS tires?
Exact wheel confirmation matters because the 1961 Citroen DS uses a 165-400 tire, and the 400 in that size refers to a millimetric rim diameter. This is not a general classic-car size that can be matched by eye to a common inch-based wheel.
Many collector cars have seen wheel changes, partial restorations, or long periods off the road, so assumptions can lead to the wrong purchase. Measuring the current wheels and confirming the car’s actual setup protects against fitment mistakes and helps preserve the DS’s intended stance, appearance, and driving character once the new tires are installed.
Restoration & Appearance
Which tire should I choose for a period-style 1961 Citroen DS?
For a period-style 1961 Citroen DS, the starting point is the correct 165-400 radial size. Because this car uses a distinctive millimetric setup, preserving the proper tire format does as much for authenticity of appearance as the tread and sidewall presentation itself.
A restoration-minded choice should support the DS’s original visual balance and avoid casual substitution with a more familiar inch-based size. When exact originality matters beyond general period style, it is worth checking marque references or restoration documentation for the specific car so the tire choice complements the rest of the vehicle correctly.
Does correct tire fitment matter for a 1961 Citroen DS restoration?
Correct tire fitment matters a great deal on a 1961 Citroen DS restoration because the car’s 165-400 radial size is part of its distinctive engineering package. The right wheel and tire format helps preserve the car’s stance, proportions, and the visual character that makes a DS look like a DS.
Beyond appearance, correct fitment also prevents restoration money from being spent on a setup that does not belong on the existing wheels. Before road use, inspect the rims, confirm that the tires match side to side, and make sure the car has not been altered in a way that changes clearance or wheel compatibility.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1961 Citroen DS?
Yes, modifications can affect tire fitment on a 1961 Citroen DS, even when the correct original tire size is 165-400. Wheel changes, brake conversions, suspension work, or body alterations can all change the relationship between the tire, wheel, and available clearance.
A DS that still appears stock may also have older changes hidden from view, especially after decades of repairs or restoration work. Confirm the actual wheel diameter and setup on the car, then check turning clearance and suspension travel before fitting new tires. That approach is especially important when the car has not been driven regularly.
What should I inspect before driving a 1961 Citroen DS on new tires?
Before driving a 1961 Citroen DS on new tires, inspect the wheels for damage, rust, or poor previous repairs and make sure the tires are mounted on the correct 400-millimeter rims. It also helps to check valve stems, inflation, and whether the tires seat evenly on the wheels.
A collector car deserves a broader walk-around before road use. Look for side-to-side clearance, steering interference, fluid leaks that could affect the tires, and signs of suspension issues that may alter how the car sits. A short, careful test drive and a second inspection afterward can reveal problems before they become larger ones.
How should 165-400 tires on a collector 1961 Citroen DS be maintained?
165-400 tires on a collector 1961 Citroen DS should be maintained with regular pressure checks, visual inspection, and careful storage habits. Even when tread looks good, low-mileage collector tires can age out from time, heat, sunlight, and long stationary periods rather than from simple wear.
Make a habit of looking for cracking, bulges, cuts, uneven wear, and slow air loss before driving. The wheels should also be checked periodically because corrosion or damage can affect tire sealing and serviceability. Keeping the car clean, dry, and away from ozone sources such as electric motors helps protect tires during longer storage intervals.
