1963 Citroen stood apart from most European makes with a range that stretched from the compact, economy-minded AMI to the technically advanced DS and ID sedans. That mix matters for tire selection, because the year’s model line does not share one universal fitment: the AMI uses a 15-inch metric radial size, while the DS and ID use a distinct 400 mm radial size tied to Citroen’s larger hydraulic cars. The real first step is identifying your exact model, since that determines not only the tire size but also the wheel diameter standard your car uses. Once that is clear, choosing the right tire becomes much more straightforward.
Which Tire Size Is Right for Your 1963 Citroen
Two tire sizes are used across 1963 Citroen models, and they vary by model rather than carrying across the full range. The AMI and the DS/ID family use different wheel diameter standards, so the key decision is confirming your exact model and wheel size first, not choosing between interchangeable alternatives. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 1963|Fit(s): AMI|Construction: Radial|Rim: 15 in
135R15 is a metric radial size with a 135 millimeter section width and a 15-inch rim diameter, following the classic Euro-metric convention that typically implies an 80-series profile. This AMI-specific size is available from Michelin and Firestone in blackwall form, with tubeless construction appearing across the marked products and speed ratings ranging from Q at 99 mph to S at 112 mph. Buyers restoring or maintaining a 1963 Citroen AMI should stay with this size, since it matches the smaller car’s wheel standard rather than the larger DS and ID setup.
Year(s): 1963|Fit(s): DS, ID|Construction: Radial|Rim: 400 mm rim
165-400 is a metric radial size that uses a 165 millimeter section width and a 400 millimeter rim diameter, making it one of the distinctive dimensional formats associated with period Citroen engineering. This size is specific to the DS and ID rather than universal across 1963 Citroen models. Owners of those larger hydraulic Citroens should confirm that their wheels are the correct 400 mm type before choosing a tire, because a 15-inch tire is not an interchangeable substitute.
Three 1963 Citroen model cores are covered here. Tire size varies by model, so year and make alone are not enough; buyers need to identify whether they have an AMI or a DS/ID-based car before moving forward.

1963 Citroen AMI
The 1963 Citroen AMI was Citroen’s practical small family car, positioned above the 2CV and known for its unconventional styling and light, economical character. Its tires mount on 15-inch wheels, which sets it apart from the larger DS and ID family and makes correct model identification especially important.
The 1963 Citroen DS was one of the most technically ambitious cars of its era, combining aerodynamic styling with Citroen’s signature hydraulic suspension and a distinctly advanced road feel. Its tire fitment uses 400 mm wheels, a hallmark of the DS family that separates it from more conventional 15-inch applications.
The 1963 Citroen ID shared the DS platform and much of its engineering character, but it was marketed as the more accessible version within the same family. Like the DS, it uses 400 mm wheel fitment, so the correct tire choice follows the larger Citroen sedan standard rather than the AMI pattern.
Three products are available across two tire sizes for 1963 Citroen vehicles. The 135R15 comes in three radial blackwall options from Michelin and Firestone, while 165-400 serves the DS and ID fitment; confirm your model and wheel diameter before selecting a tire.
These FAQs focus on the split between AMI 15-inch fitment and DS/ID 400 mm fitment, along with sidewall, tube, speed-rating, and collector-car care questions that matter when sorting out a 1963 Citroen.
Size Basics & Fitment
What tire sizes fit 1963 Citroen vehicles?
1963 Citroen vehicles use two different tire sizes depending on model. The AMI uses 135R15, which mounts on a 15-inch rim. The DS and ID use 165-400, which mounts on a 400 mm rim. Those are not the same wheel standards, so the fitment break is by model family rather than by trim preference or driving style.
That means the first thing to verify on a 1963 Citroen is whether you have an AMI or a DS/ID-series car. If you are working from loose wheels or a long-stored project, measure the rim and confirm the model before choosing a tire. A 15-inch tire will not correctly fit a 400 mm wheel, and a 400 mm tire will not fit a 15-inch wheel.
What does 135R15 mean on a 1963 Citroen tire?
On a 1963 Citroen AMI, 135R15 is a Euro-metric radial size. The 135 refers to a nominal section width of 135 millimeters, the R identifies radial construction, and the 15 is the rim diameter in inches. In period European sizing, a metric radial written this way generally follows the traditional 80-series convention even when the aspect ratio is not spelled out in the size code.
For an AMI owner, that decoding matters because it confirms both the construction type and the wheel diameter standard. It also helps when comparing product markings such as 135R15 and 135SR15, where the extra speed symbol identifies service rating rather than a different basic fitment. The most important point is that this size belongs to the AMI family, not the larger DS and ID cars.
Do all 1963 Citroen models use the same tire size?
No, 1963 Citroen models do not all use the same tire size. The AMI uses 135R15, while the DS and ID use 165-400. Citroen was building very different vehicles in 1963, from a compact economy car to its larger hydraulic flagship family, so the tire and wheel standards were different across the range.
That distinction is especially important for restorations and cars that have changed hands several times. If someone tells you only that the car is a 1963 Citroen, that is not enough to choose a tire correctly. Confirm the exact model first, then confirm the wheel diameter on the car, especially if you are dealing with a project that may have had wheels swapped at some point in its life.
Buying the Right Tire
What sidewall styles are available for 1963 Citroen tires?
The 135R15 options for 1963 Citroen AMI applications are available in blackwall form. That suits the understated, European small-car look that is commonly associated with compact Citroen fitments of the period. Sidewall appearance matters visually even when the basic size is correct, because it changes how original or era-appropriate the car looks once it is on the road or on display.
If your goal is a factory-style presentation, sidewall style should be part of the decision along with size and construction. For many European cars of the early 1960s, a simple blackwall appearance is the expected visual choice. On a driver, it also keeps the focus on correct fitment and proper wheel compatibility rather than adding a styling cue that may not match the character of the car.
What brands make tires for 1963 Citroen vehicles?
Michelin and Firestone both cover 1963 Citroen applications in the 135R15 size used by the AMI. Michelin appears in both the Michelin X M+S 89 and ZX series, while Firestone offers the F560 Radial in the same base size. Those names reflect different product families within the same fitment category rather than different wheel standards.
Brand choice becomes meaningful after the size is settled. On an AMI, you can compare product character within 135R15 while staying on the correct 15-inch wheel. On a DS or ID, the first question is not brand but wheel standard, because the 165-400 fitment belongs to a different dimensional system. Matching the right size to the right Citroen model comes before comparing brand preferences.
What is the difference between Michelin ZX and Firestone F560 Radial for the 1963 Citroen?
For a 1963 Citroen AMI, both the Michelin ZX and Firestone F560 Radial are 135R15 radial tires for 15-inch wheels, but their marked details are not identical. The Michelin ZX carries a 135SR15 72S marking, which indicates an S speed rating up to 112 mph, and it fits 3.50 to 4.50 inch rims. The Firestone F560 Radial is also a blackwall radial in 135R15, fits 3.50 to 4.50 inch rims, and carries a maximum load figure of 780 pounds at 44 psi.
That makes the comparison less about basic fitment and more about the character of the specific reproduction tire. Both suit the AMI size requirement, but the sidewall marking details and published specifications differ slightly. If you are choosing between them, confirm the exact wheel width on the car and decide whether original-style brand identity, sidewall marking style, or the published load and service markings matter more for your particular project.
Fitting & Setup
What rim width do 1963 Citroen tires require?
For 1963 Citroen AMI applications in 135R15, published rim width guidance appears at 3.50 to 4.50 inches on the Michelin ZX and Firestone F560 Radial. That gives AMI owners a clear working range for the 15-inch wheels used with this size. The DS and ID use the separate 165-400 fitment, so the first wheel question there is confirming that the car still has the correct 400 mm rims.
Rim width and rim diameter are different checks, and both matter. A tire can have the correct overall size code yet still be a poor match if the wheel width falls outside the tire maker’s approved range. On an AMI, confirm both the 15-inch diameter and the wheel width before final selection. On a DS or ID, establish the correct 400 mm wheel first before moving on to any finer fitment details.
Do 1963 Citroen tires require inner tubes?
Tube requirements depend on the exact 1963 Citroen tire product and the wheel it is being mounted on. In the 135R15 AMI fitment, marked products include tubeless examples such as 135R15 72 Q TL and 135SR15 72S TL, while another 135R15 product is not marked the same way in its size line. That means tube status can vary by product, and it should not be assumed across every tire carrying the same size code.
The practical rule is to check both the tire marking and the wheel design before installation. An original wheel condition issue, an older rim profile, or a manufacturer’s recommendation may still lead an experienced installer to use a tube even when the tire itself is tubeless-capable. For a collector Citroen, that decision is best made at mounting time after the exact tire and wheel are both confirmed.
Maintenance, Storage & Longevity
How should I store a 1963 Citroen when the tires are fitted?
A stored 1963 Citroen should be kept out of direct sunlight, away from electric motors and ozone sources, and on a clean, dry surface rather than bare earth. Tire pressures should be maintained during storage, and the car should be moved periodically or supported in a way that reduces long static loading on one contact patch. Those habits help preserve sidewalls, tread shape, and overall casing condition on a collector car that may spend long stretches parked.
Storage matters just as much on an infrequently driven European classic as it does on a show car. Flat-spotting, sidewall aging, and moisture exposure often become problems before tread wear does. If your 1963 Citroen will sit for a season, make tire care part of the storage routine along with battery, fuel, and brake-system preparation so the car is ready for safe use when it comes back out.
How long do tires on a 1963 Citroen typically last?
On a 1963 Citroen, tire life is usually governed more by age than mileage. Collector-car tires are often evaluated carefully once they reach about five to seven years of service, and many owners begin serious replacement consideration as they approach ten years, regardless of remaining tread depth. The DOT date code on the tire is the best starting point for understanding its age, especially on a car that sees occasional use.
That age-based approach is important because a lightly driven AMI, DS, or ID can still wear out its tires chemically rather than mechanically. Sidewall cracking, hardening rubber, and long-term loss of flexibility can all appear before the tread looks used up. If the age of the tire is unclear, or if the car has been parked for years, a thorough inspection is more valuable than relying on appearance alone.
How often should tires on a 1963 Citroen be inspected?
Tires on a 1963 Citroen should be inspected before every drive and again before any longer outing. Look for sidewall cracking, embedded debris, cuts, bulges, irregular wear, and pressure loss, and make sure the spare is still serviceable as well. On a car that has been sitting, the first inspection after storage should be especially thorough because time and inactivity can be harder on collector tires than routine local driving.
Frequent inspection is a simple habit that helps catch small problems before they become roadside failures. If your 1963 Citroen uses tube-dependent wheel and tire combinations, pay close attention to valve stems and any signs of slow leakage. It is also wise to recheck pressures after the first short drive of the season, since a tire that appears fine in the garage may reveal issues only once it is back in use.
Restoration & Authenticity
What tires were originally fitted to the 1963 Citroen AMI?
A 1963 Citroen AMI would have been a radial-era European car, and its correct fitment family is represented here by 135R15. That aligns with Citroen’s long association with metric radial tire practice in this period. Original-equipment brand selection can vary by market and delivery history, so the safest authenticity point is the correct size, radial construction, and period-appropriate appearance rather than assuming one universal brand for every AMI built.
For a restoration, start by matching the AMI to 135R15 on the correct 15-inch wheels and then refine the choice by sidewall look and brand character. If the car is being judged, consult a marque club or model specialist for country-specific or trim-specific expectations. Restored European cars often gain or lose authenticity points on details that go beyond basic size, especially when export-market histories are involved.
Does correct tire fitment matter for showing a 1963 Citroen?
Correct tire fitment matters a great deal when showing a 1963 Citroen, because judges and knowledgeable enthusiasts notice size, construction type, wheel standard, and sidewall appearance quickly. An AMI wearing 135R15 radial blackwalls presents very differently from a DS or ID on 165-400 fitment, and mixing those standards would be an obvious error. On European cars of this era, getting the dimensional language right is part of presenting the car faithfully.
Even outside formal concours events, proper fitment changes the stance and visual credibility of the car. A tire that technically mounts but carries the wrong profile, wrong wheel standard, or wrong sidewall character can make a well-restored Citroen look off immediately. If authenticity is a priority, use factory literature, period photos, and marque-club guidance to confirm what is correct for your exact model and market version.
What tires were originally fitted to the 1963 Citroen DS?
A 1963 Citroen DS belongs to the 165-400 radial fitment family, reflecting Citroen’s distinctive use of metric wheel sizing on its larger hydraulic cars. The essential originality points are the 165 millimeter width class, radial construction, and the 400 mm wheel standard. That combination is far more important to authenticity than guessing at a universal original-equipment brand, since delivery markets and later service history can influence what a surviving DS wears today.
For restoration work, the biggest risk is confusing a 400 mm Citroen application with a more familiar 15-inch tire simply because the overall proportions look close at a glance. They are not interchangeable. If your DS is being returned to show-level presentation, confirm the wheel standard first, then use period Citroen references and DS specialists to verify any finer points of finish, sidewall appearance, or market-specific expectations.
Safety & Road Use
Are 1963 Citroen tires safe for highway driving?
1963 Citroen tires can be appropriate for highway driving when the correct size is used, the tire is in sound condition, and its service rating matches the intended use. In the 135R15 AMI fitment, available speed ratings include Q, which corresponds to 99 mph, and S, which corresponds to 112 mph. Those ceilings are above ordinary U.S. highway speeds, but safe real-world travel still depends heavily on the condition of the car itself, including suspension, steering, brakes, and wheel integrity.
The practical takeaway is to think of the tire as one part of the system rather than the whole answer. A well-sorted 1963 Citroen on fresh, correct tires is very different from a long-stored car with aged rubber and deferred maintenance. Before sustained highway use, confirm tire age, pressure, and condition, then make sure the rest of the car is equally ready for modern traffic conditions.
What inflation pressure should I use for 1963 Citroen tires?
Inflation pressure on a 1963 Citroen should follow the vehicle manufacturer’s recommendation for the car and the tire maker’s guidance for the exact tire being used. In the 135R15 AMI fitment, one radial carries a maximum load of 780 pounds at 44 psi, but that is a maximum-load reference point, not automatically the day-to-day running pressure for every 1963 Citroen application. Pressure should never be transferred casually from one size or model family to another.
The safest approach is to start with the original owner’s manual or factory tire-pressure decal for your specific model, then compare that against the tire manufacturer’s instructions for the product you choose. That matters especially on a make like Citroen, where AMI and DS/ID fitments differ significantly. Proper pressure affects ride quality, wear, steering response, and casing durability, so it is worth confirming carefully before regular use.
What should I check before taking a 1963 Citroen on a longer drive?
Before a longer drive in a 1963 Citroen, inspect every tire for cracking, cuts, bulges, uneven wear, and proper inflation, and check the spare as well. Look closely at valve stems and bead areas, especially on cars that have sat for long periods or use wheel and tire combinations that may involve tubes depending on the product and wheel. Tire age should be part of the check, not just visible tread depth.
That tire inspection should be part of a broader pre-drive review that suits the age and complexity of the car. On a Citroen, especially a DS or ID, the wider mechanical condition of the suspension, braking, and hydraulic systems also deserves attention before a sustained trip. Good tires are essential, but on a vintage French car they work best when the rest of the chassis and running gear are equally prepared.
