The 1966 Citroen ID belongs to an era when Citroen was pushing family-car engineering in a very different direction, pairing sleek French styling with the ride quality and road manners that made the ID and DS line so distinctive. For tire selection, that character matters because this car uses radial construction, with fitments centered around 180-380 and 185R15. That leaves the real choice focused less on bias-ply-versus-radial conversion and more on selecting the right radial format, sidewall presentation, and tire series for the car’s intended look and use. A restoration-minded ID owner should also confirm the actual wheel setup before choosing between millimetric and inch-based radial sizes.
Which Tire Size Is Right for The 1966 Citroen ID
The 1966 Citroen ID uses two primary tire sizes, and both are radial fitments. The first step is confirming which wheel setup is on the car, because one size is a millimetric Citroen-style fitment and the other is a 15-inch radial. On the ID 19 Sedan, both sizes are associated with the model, so the practical decision is matching the car’s actual wheels and then choosing the sidewall style, brand, and tire series that suit the intended presentation.
The 180-380 size uses a metric-style designation in which 180 refers to nominal section width and 380 refers to the wheel diameter in millimeters rather than inches. Even though the numbering can look unfamiliar to modern buyers, this is a radial fitment associated with the 1966 Citroen ID and reflects the car’s period European tire practice. It is a size worth evaluating when the car retains its original-style wheel arrangement and the goal is to stay close to the traditional fitment approach. Wheel identification should come before tire selection here, since the millimetric designation does not correspond to a standard 15-inch rim.
A 185R15 is a Euro-metric radial with a nominal section width of 185 millimeters, radial construction, and a 15-inch rim diameter. On a 1966 Citroen ID, this size opens up the broadest visible product choice, including options from Coker Classic, Michelin, Avon, and Universal Vintage Tire, along with Blackwall, Narrow Whitewall, and Redline sidewall treatments. Tire series such as Michelin XVS, Coker Classic Radial, Universal Sport, and Turbosteel CR3B give the buyer different appearance and specification choices within the same basic fitment. It is the more familiar modern-format size, but wheel width and actual vehicle setup still need to be confirmed before making a final choice.
Sub-model fitment is straightforward here because the covered 1966 Citroen ID 19 Sedan is associated with both primary tire sizes. The important step is not trim identification so much as confirming which wheel and tire setup is actually on the car before selecting a replacement.

Tire Size & Fitment
What tire size fits a 1966 Citroen ID?
The 1966 Citroen ID is associated with two radial tire sizes: 180-380 and 185R15. The covered sub-model, the 1966 Citroen ID 19 Sedan, can use either of those fitments depending on the wheel setup on the car.
The key step is confirming the wheels before ordering tires. A 180-380 tire uses a millimetric wheel diameter, while a 185R15 uses a 15-inch rim, so the size on the sidewall and the actual wheel dimensions need to agree. Many cars in collector use have changed wheels over time, and that matters more here than simply identifying the model name.
What size rim does a 1966 Citroen ID use?
A 1966 Citroen ID uses a 15-inch rim when fitted with 185R15 tires. The other primary fitment, 180-380, uses a millimetric wheel diameter rather than a conventional 15-inch designation, so it should not be treated as the same wheel fitment simply because the tire appears close in overall size.
Wheel confirmation matters before choosing between the two tire sizes. Check the wheel markings, measure carefully if needed, and compare the existing tire size on the car. That step helps avoid mixing a millimetric tire standard with an inch-based rim and also helps narrow the product choices to the tires that actually match the wheel arrangement.
What does 180-380 mean on a 1966 Citroen ID?
On a 1966 Citroen ID, 180-380 is a radial tire size written in a European millimetric format. The 180 refers to nominal section width in millimeters, and the 380 refers to wheel diameter in millimeters rather than inches, which is why the size looks different from a more familiar 185R15 marking.
That distinction is important because a millimetric fitment should be matched to the correct wheel type. A buyer comparing 180-380 with 185R15 should not assume they mount on the same rim. Looking at the car’s present wheels, checking the tire markings already installed, and confirming the intended setup are the best next steps before choosing a replacement.
Choosing the Right Tire
What should I consider when choosing a 185R15 tire for a 1966 Citroen ID?
Start with the basics: the tire must be a 185R15 radial for a 15-inch wheel, and the wheel width should fall within the product’s accepted range. From there, the meaningful differences are brand, tire series, sidewall style, weight, and any stated load information tied to that specific tire.
A 1966 Citroen ID owner often ends up choosing between appearance and usage priorities rather than between different primary sizes. Michelin XVS, Coker Classic Radial, Universal Sport, and Avon Turbosteel options all present the car a little differently. Once the wheel setup is confirmed, compare sidewall treatment, rim-width compatibility, and the character you want the car to show at a glance.
What sidewall styles are available for 1966 Citroen ID tires?
For 185R15 fitments on a 1966 Citroen ID, the available sidewall styles include Blackwall, Narrow Whitewall, and Redline. Those treatments appear across several radial product lines, so the visual choice is broader than simply picking a single brand or one generic 185R15 tire.
The right sidewall depends on how the car is being presented. Blackwall gives the most understated look, Narrow Whitewall adds a more formal touring flavor, and Redline creates a sportier period-style appearance. Once the wheel size is confirmed, the sidewall decision becomes one of the easiest ways to shape the finished look without changing the underlying radial fitment.
What brands offer tires for the 1966 Citroen ID?
The 185R15 tire options for a 1966 Citroen ID include products from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those choices span several tire series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport.
Brand choice should still come after confirming the actual wheel setup and correct tire size. Once that is settled, compare each product by sidewall style, rim-width compatibility, load information where stated, and the overall presentation you want on the car. A French sedan with strong design character often benefits from a tire choice that supports both its proportions and its intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1966 Citroen ID?
A period-style 1966 Citroen ID tire choice starts with the wheel setup already on the car. If the car retains its millimetric arrangement, 180-380 keeps the selection anchored to that traditional Citroen-style fitment. If it runs on 15-inch wheels, a 185R15 radial keeps the car in an era-appropriate radial format while opening up more visible product choices.
After size is settled, appearance becomes the next decision. Blackwall, Narrow Whitewall, and Redline sidewalls each change the character of the car without changing the basic radial construction. For buyers chasing a highly exact restoration, the best approach is to verify historic references for the individual car before treating any one sidewall treatment or brand as the final visual answer.
Does correct tire fitment matter for a 1966 Citroen ID restoration?
Correct tire fitment matters on a 1966 Citroen ID because the car’s stance and visual balance depend heavily on the wheel-and-tire relationship. The difference between 180-380 and 185R15 is not just cosmetic; it reflects two distinct fitment approaches, one millimetric and one inch-based.
A restoration-minded owner should avoid choosing by appearance alone. The right first step is confirming the wheel type currently on the car and deciding whether the goal is to preserve the existing setup or return to a more traditional one. Once that is clear, sidewall style and tire series can refine the look without blurring the basic fitment requirements.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1966 Citroen ID?
Yes, modifications can affect tire fitment on a 1966 Citroen ID. Wheel changes, altered ride height, suspension work, or body adjustments can all change how a tire clears the fenders, suspension components, and steering range, even when the tire is in one of the correct primary sizes for the model.
That matters even more on a car that may have moved between millimetric and 15-inch wheel setups during its life. A careful check should include wheel diameter, wheel width, tire-to-body clearance, and steering clearance at full lock. Collector cars are often changed over time, so the actual configuration on the car should guide the tire decision rather than assumption.
What should I inspect before driving a 1966 Citroen ID on new tires?
Before driving a 1966 Citroen ID on new tires, inspect the wheels for damage or distortion, confirm that all tires match the intended size, and set inflation pressure to the appropriate specification for the tire and vehicle use. It is also wise to check valve stems, wheel hardware, and general suspension condition.
A short, careful road test is a smart next step after installation. Pay attention to steering response, any sign of rubbing, and whether the car tracks cleanly. On a collector vehicle that may sit for long periods, it also helps to inspect older tires that are being removed for cracking, bulges, uneven wear, or air-loss patterns that could point to broader wheel or chassis issues.
How should tires on a collector 1966 Citroen ID be maintained?
Tires on a collector 1966 Citroen ID should be inspected regularly for cracking, cuts, bulges, flat spotting, and uneven wear, especially if the car is driven infrequently. Correct inflation pressure and clean, dry storage conditions make a real difference for a vintage car that may spend long periods parked between outings.
Road-use readiness is about condition as much as tread depth. Occasional movement, protection from prolonged sun and ozone exposure, and prompt attention to slow air loss all help preserve the tires. Before any longer drive, check pressure, examine the sidewalls closely, and confirm that the tires still suit the wheel setup currently on the car.
