The 1957 Citroen ID arrived in the same remarkable family as the DS, bringing advanced French engineering and unmistakable styling to a broader touring audience. Its long, low stance and distinctive ride character make tire choice especially important for owners who want the car to look right and drive in a manner that suits its period character. The 1957 Citroen ID uses a 165-400 radial, a millimetric radial size that stands apart from more familiar inch-based American sizing. For many owners, the real decision is preserving that proper size format while choosing a tire that suits restoration goals and intended road use.
Which Tire Size Is Right for The 1957 Citroen ID
The 1957 Citroen ID uses one primary tire size: 165-400. It is a radial fitment in a classic metric millimetric format, so the key question is not which primary size fits, but how to understand that sizing system and confirm that the car still has the correct wheel setup. The covered sub-model shares this same size.
The 165-400 size uses a metric-style width designation, with 165 indicating nominal section width in millimeters and 400 identifying a millimetric rim diameter rather than a more familiar 15-inch or 16-inch wheel. This is a radial tire format, which matches the primary fitment used on the 1957 Citroen ID and reflects the car's distinctly European tire specification. For an owner, the most important point is recognizing that 400 denotes the wheel standard itself, not a close inch-based substitute. That makes wheel confirmation essential before selecting replacement tires for road use or restoration work.
Fitment is straightforward for the covered 1957 Citroen ID sub-model. The main point is confirming that the car is the ID 19 Sedan and still uses the proper millimetric wheel setup for the 165-400 radial size.

The 1957 Citroen ID 19 Sedan uses the same 165-400 radial fitment as the model core, so tire selection centers on choosing the proper millimetric radial rather than sorting through multiple primary sizes. That keeps the focus on wheel confirmation, tire condition, and maintaining the car's intended road manners and appearance.
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
Common 1957 Citroen ID tire questions usually center on the 165-400 size itself, the millimetric rim standard, restoration-minded tire selection, and the checks worth making before putting a collector Citroen back on the road.
Tire Size & Fitment
What tire size fits a 1957 Citroen ID?
The 1957 Citroen ID uses a 165-400 radial tire. For the covered fitment, that is the primary tire size associated with the vehicle, and the 1957 Citroen ID 19 Sedan uses that same size as well.
The important detail is that 165-400 is a millimetric fitment, not a typical inch-based American size. Before choosing a replacement, confirm that the car still has the correct wheel setup and has not been changed to another rim standard over the years. That step matters just as much as the tire size itself on a vintage Citroen.
What size rim does a 1957 Citroen ID use?
A 1957 Citroen ID with the 165-400 tire size uses a 400-millimeter rim standard. That millimetric designation is part of the tire size itself and is a key part of the vehicle's original-style fitment approach.
That means a replacement decision should begin with the wheel on the car, not just the sidewall width. A wheel measured in inches is not automatically the same thing as a 400-millimeter rim, even if it appears close at a glance. Verifying the wheel standard helps avoid mounting mistakes and keeps fitment consistent with the Citroen's intended setup.
Does the 1957 Citroen ID 19 Sedan use the same tire size?
Yes. The 1957 Citroen ID 19 Sedan uses the same 165-400 radial tire size as the model core. There is no separate primary tire size shown for that covered sub-model.
That simplifies the search, but it still leaves one important check: making sure the sedan still has the proper millimetric wheels and has not been converted to a different wheel and tire combination during its life. On collector cars, wheel swaps and older replacement parts can change what is actually on the vehicle even when the original fitment is straightforward.
Choosing the Right Tire
What should I consider when choosing a 165-400 tire for a 1957 Citroen ID?
Start with the correct 165-400 size and the fact that the 1957 Citroen ID uses a radial in a millimetric format. The first priority is matching the proper wheel standard, since this is not a conventional inch-rim size.
After that, think about how the car will be used. A restoration-minded owner may focus on preserving the right overall presentation, while a driver may place more emphasis on condition, age, and consistency across all four tires. Checking the actual wheels on the car, along with clearance and general chassis condition, helps keep the final choice aligned with the vehicle's setup.
How do I choose between the available 165-400 tires for a 1957 Citroen ID?
Choosing among 165-400 tires for a 1957 Citroen ID begins with staying in the correct size and radial construction. Because the car uses a specialized millimetric fitment, size accuracy and wheel compatibility matter more than trying to substitute a more familiar modern code.
From there, compare the tire's intended character with your goals for the car. Some owners want a more restoration-oriented presentation, while others are mainly preparing a driver for regular road use. It also helps to inspect the existing wheel and suspension setup so the final tire choice suits the car as it sits today, not just how it left the factory era.
What rim-fitment details matter when choosing 1957 Citroen ID tires?
The most important rim-fitment detail on a 1957 Citroen ID is that the 165-400 tire is built for a 400-millimeter wheel standard. That millimetric specification is central to the tire choice and should be treated as a fitment requirement, not a minor detail.
A careful owner should confirm the wheels actually on the car before mounting replacement tires, especially on a vehicle that may have been restored, stored, or modified over many decades. Wheel changes, mixed parts, or prior conversions can alter what fits safely. Looking at wheel condition, bead-seat compatibility, and general clearance helps prevent problems once the car is back on the road.
Restoration & Appearance
Which tire should I choose for a period-style 1957 Citroen ID?
For a period-style 1957 Citroen ID, the right starting point is the proper 165-400 radial size. Keeping the original-style millimetric fitment preserves the proportions and visual character that suit the car's late-1950s European design.
A restoration-minded choice is usually less about chasing novelty and more about staying faithful to the car's intended tire format. Owners seeking exact historical accuracy should also compare their car against marque references, restoration records, and surviving original examples. That extra step can help confirm whether the overall wheel-and-tire presentation matches the goal of the build.
Does correct tire fitment matter for a 1957 Citroen ID restoration?
Yes, correct tire fitment matters a great deal on a 1957 Citroen ID restoration. The 165-400 radial is part of the car's visual stance and its specialized European wheel standard, so an incorrect substitute can change both appearance and setup.
Even on a car that is driven only occasionally, the wheel-and-tire combination should reflect the proper size system rather than an approximate modern shortcut. A restoration can look right from a distance but still lose authenticity in its tire presentation if the fitment is off. Checking the wheels early in the project helps avoid rework later.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1957 Citroen ID?
Yes. Modifications can absolutely affect tire fitment on a 1957 Citroen ID, especially if the car has been changed from its original millimetric wheel setup. Aftermarket wheels, suspension work, ride-height changes, or body repairs can all influence what tire and wheel combination is actually on the car.
That is why a replacement search should begin with the vehicle in its current condition, not assumptions about untouched factory configuration. Checking wheel standard, wheel condition, steering clearance, and fender space is especially important on an older Citroen. Small changes made years ago can have a big effect on what fits properly today.
What should I inspect before driving a 1957 Citroen ID on new tires?
Before driving a 1957 Citroen ID on new tires, inspect the wheels, valve stems, and the general condition of the suspension and steering components. The tires themselves should be checked for proper inflation, secure mounting, and any signs of interference once installed.
A short, careful test drive is a smart next step on a collector car, especially one with a specialized wheel standard. Listen for rubbing, feel for pull or vibration, and recheck pressure after the first outing. It also helps to confirm that the spare and any older remaining tires are not badly mismatched in age, condition, or construction.
How should 165-400 tires on a collector 1957 Citroen ID be maintained?
165-400 tires on a collector 1957 Citroen ID should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Even tires with low mileage can deteriorate from time, storage conditions, and long periods of inactivity.
Look over the sidewalls and tread for cracking, bulges, cuts, and uneven wear, and keep the car stored away from prolonged sunlight, excess moisture, and ozone sources when possible. Occasional use does not eliminate the need for inspection on a vintage car. A tire that still holds air can still be too old or too compromised for dependable road use.
