In 1964, Citroen stood apart from most European makers by pairing advanced engineering with distinctly French packaging, from the compact Ami to the larger DS and ID sedans. That range matters when choosing tires, because 1964 Citroen models did not all use the same size across the lineup. The Ami uses one 15-inch radial size, while the DS and ID share a different radial size built around Citroen’s metric 400 mm wheel system, so the choice comes down to identifying the exact model first and then matching the correct wheel diameter. Before selecting a tire, confirm whether your car is an Ami, DS, or ID and check the wheel itself for the proper diameter.
Which Tire Size Is Right for Your 1964 Citroen
Two tire sizes are used across 1964 Citroen vehicles, and they vary by model rather than being shared across the full range. The real decision starts with wheel diameter: the Ami uses a 15-inch radial, while the DS and ID use a metric 400 mm radial, so identifying the model and confirming the wheel is more important than comparing tread patterns first. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 1964|Fit(s): AMI|Construction: Radial|Rim: 15 in
135R15 is a Euro-metric radial size that denotes a 135 millimeter section width, radial construction, and a 15-inch rim diameter, with the aspect ratio conventionally treated as an 80-series profile. This size is specific to the 1964 Citroen AMI rather than the full Citroen range, and it is available from Michelin and Firestone in blackwall form; tubeless status varies by product, and speed markings range from Q and S to products without a speed letter in the size description. For an Ami owner, this is the correct starting point when keeping the car on its proper 15-inch wheels, especially if you want a narrow radial that suits a light French economy car.
Year(s): 1964|Fit(s): DS, ID|Construction: Radial|Rim: 400 mm rim
165-400 uses Citroen's metric wheel convention, with a nominal 165 millimeter section width and a 400 millimeter rim diameter rather than a 15-inch wheel. This size is specific to the 1964 Citroen DS and ID, both of which share the same metric-wheel tire requirement. For DS and ID owners, the practical takeaway is simple: confirm that your car still carries its original-style 400 mm wheels, because this size is not interchangeable with the Ami's 15-inch fitment.
Three Citroen models are covered for 1964. Tire size varies by model, so year and make alone are not enough here: the Ami uses a 15-inch radial, while the DS and ID use a different size on metric 400 mm wheels. Select your model below to narrow the fitment history and tire choices to the car you actually own.
1964 Citroen AMI
The 1964 Citroen Ami was Citroen's practical small family car, positioned above the 2CV but still built around light weight, efficiency, and unconventional French design. Its tires mount on 15-inch wheels, which sets it apart from the larger hydraulic Citroens in the lineup and makes model identification especially important before choosing a tire.
The 1964 Citroen DS was one of the most technically ambitious production cars of its era, known for its aerodynamic shape, advanced suspension, and distinctive road manners. Its tires mount on 400 mm metric wheels, a hallmark detail that separates DS fitment from more conventional 15-inch applications.
The 1964 Citroen ID shared the DS family's basic architecture and unmistakable styling, but it was positioned as a more accessible version of Citroen's flagship sedan. Like the DS, it uses 400 mm metric wheels, so tire selection begins with preserving that original wheel standard rather than crossing over to inch-based sizes.
Three products are available across one tire size for 1964 Citroen vehicles. In 135R15, Michelin and Firestone cover the radial blackwall options for the AMI; tube status and speed markings can vary by product, so confirm the exact sidewall marking before selecting.
These FAQs focus on the split between Ami 15-inch fitment and DS/ID metric-wheel fitment, along with radial size decoding, sidewall and brand choices, and the care vintage Citroen tires need when the car is driven only occasionally.
Size Basics & Fitment
What tire sizes fit 1964 Citroen vehicles?
1964 Citroen vehicles use two different tire sizes across three model lines. The Citroen AMI uses 135R15 on a 15-inch rim, while the Citroen DS and Citroen ID use 165-400 on a 400 mm metric rim. For 135R15, products fit rims from 3.50 to 4.50 inches wide where rim-width guidance is stated.
That split means a 1964 Citroen owner needs to identify the exact model before moving any farther in the tire search. The Ami follows a conventional inch-based wheel diameter, while the DS and ID follow Citroen's metric wheel system, so the wheel itself should be checked before any tire is chosen. Once the model and wheel diameter are confirmed, the remaining choice is much simpler.
What does 135R15 mean on a 1964 Citroen tire?
On a 1964 Citroen, 135R15 is a Euro-metric radial size. The 135 refers to nominal section width in millimeters, the R indicates radial construction, and the 15 is the wheel diameter in inches. Because no aspect ratio is stated, this format is conventionally treated as an 80-series radial.
For a 1964 Citroen AMI, that code tells you the tire belongs on a conventional 15-inch wheel, not on the DS or ID's metric wheel system. It also helps explain why these tires look relatively narrow by modern standards. If you are comparing options within 135R15, focus on the exact sidewall marking, speed symbol, and whether the product is marked tubeless.
Do all 1964 Citroen models use the same tire size?
No, 1964 Citroen models do not all use the same tire size. The AMI uses 135R15, while the DS and ID share 165-400. Even though all of these are radial applications, the wheel diameters are different, so the sizes are not interchangeable across the whole Citroen lineup.
That matters because many buyers know they have a 1964 Citroen but have not yet narrowed the search to Ami, DS, or ID. On this particular year and make, model identification is essential rather than optional. If the car has been restored or modified over time, inspect the wheels directly so you can confirm whether the car still carries its original diameter standard.
Buying the Right Tire
What sidewall styles are available for 1964 Citroen tires?
For 1964 Citroen fitment with current product coverage, 135R15 is available in blackwall form. That matches the understated, European look many small and midsize French cars of the period wore, especially on practical models such as the Ami. No alternate sidewall treatment appears within the 135R15 products covered here.
For many owners, that makes the sidewall decision straightforward: the visual question is less about whitewall versus blackwall and more about choosing the right tread pattern, brand character, and exact sidewall marking. If your goal is restoration accuracy, blackwall remains the natural first choice for a 1964 Citroen AMI. DS and ID owners should first confirm the correct metric-wheel tire before worrying about appearance details.
What brands make tires for 1964 Citroen vehicles?
1964 Citroen AMI coverage in 135R15 comes from Michelin and Firestone. Michelin appears in both the ZX and X M+S 89 series, while Firestone offers the F560 Radial in the same basic size. Those choices keep the AMI in a narrow radial format that suits the car's original design intent.
Brand choice on a vintage Citroen often comes down to the kind of driving you do and the sidewall details you prefer. Michelin naturally carries strong period and European-market associations for French cars, while Firestone gives another radial option in the same size. Before deciding between them, compare the exact speed marking and sidewall wording on the tire you are considering.
What is the difference between Michelin ZX and Firestone F560 Radial for a 1964 Citroen AMI?
For a 1964 Citroen AMI in 135R15, Michelin ZX and Firestone F560 Radial are both radial blackwall tires, and both fit a 15-inch wheel. Michelin ZX is marked 135SR15 72S TL and is shown for 3.50 to 4.50 inch rims at 12 pounds, while Firestone F560 Radial is a 135R15 tire at 13.2 pounds with a maximum load figure of 780 pounds at 44 psi and the same 3.50 to 4.50 inch rim range.
In practical terms, that means the two tires share the same basic fitment but differ in sidewall marking details, weight, and the presence of an explicit load-and-pressure figure. A buyer comparing them should look closely at the sidewall code, the intended visual style, and whether a speed symbol matters for the way the car will be driven. Matching the tire to the wheel width remains part of that decision.
Fitting & Setup
What rim width do 1964 Citroen tires require?
For 1964 Citroen AMI fitment in 135R15, the rim width range is 3.50 to 4.50 inches on the products where rim-width guidance appears. That is the relevant sizing window for both Michelin ZX and Firestone F560 Radial in this application. The wheel diameter remains 15 inches for the AMI.
Rim width matters because a narrow vintage radial is designed to sit correctly on a correspondingly narrow wheel. If the wheel is too wide or too narrow, the sidewall shape and tread profile can change in ways that affect appearance and road feel. On a 1964 Citroen, always verify the actual wheel dimensions before mounting a modern reproduction radial.
Do 1964 Citroen tires require inner tubes?
For 1964 Citroen AMI fitment in 135R15, inner-tube status varies by product. Michelin X M+S 89 and Michelin ZX are marked TL, which indicates tubeless construction, while the Firestone F560 Radial does not carry a tube marking in the size description. That means the exact tire marking should be checked rather than assuming one rule covers every 135R15 option.
The practical takeaway is to match the tire not only to the car, but also to the wheel condition and wheel design. An original wheel may still need careful inspection for bead-seat condition, corrosion, and valve-stem sealing even when the tire itself is tubeless. If there is any doubt, a tire professional familiar with vintage European wheels can help determine the proper setup.
Maintenance, Storage & Longevity
How should I store a 1964 Citroen when the tires are fitted?
A 1964 Citroen should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Keep the tires clean and properly inflated, and move the car periodically so it does not sit on one contact patch for months at a time. Radial tires generally resist flat-spotting better than old-style bias-ply tires, but long static storage can still age the casing and sidewalls.
That advice is especially important for collector Citroens that spend more time parked than driven. If the car will be stored for a very long period, some owners use tire cradles or support the vehicle to reduce load on the tires, while still following safe storage practices. Preserving the tires also protects ride quality and helps avoid surprise failures when the car returns to the road.
How long do tires on a 1964 Citroen typically last?
On a 1964 Citroen, tire age usually matters more than mileage because many collector cars are driven sparingly. A sensible rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat ten years as a point where replacement deserves serious consideration, regardless of remaining tread. The DOT date code on the tire helps establish that timeline.
A lightly driven Ami, DS, or ID can still wear old-looking tires that seem fine at a glance but are no longer ideal for road use. Sidewall cracking, hardening rubber, and long-term storage effects often show up before the tread is actually worn out. If the tires are several years old and the car is going back into regular use, age should be part of the decision, not just appearance.
How often should tires on a 1964 Citroen be inspected?
Tires on a 1964 Citroen should be checked before every drive and given a more thorough inspection before any longer outing. Look for cracks in the sidewall, cuts, bulges, irregular tread wear, and slow pressure loss. If the tire setup uses tubes, the valve stems and any signs of tube-related leakage deserve extra attention as well.
Routine inspection is especially important on vintage cars because they may sit for weeks and then be expected to run at road speed with little warning. A careful walkaround takes only a few minutes and can catch age-related problems before they become a roadside issue. For a car with uncommon wheel standards such as a DS or ID, that habit is even more valuable.
Restoration & Authenticity
What tires were originally fitted to the 1964 Citroen AMI?
A 1964 Citroen AMI would have been a radial-tire car in period, and 135R15 is the size associated with the model here. That aligns with Citroen's early and influential use of radial construction in everyday passenger cars. Original-equipment branding could vary by market and supply, so the key restoration points are the correct size, radial construction, and an appropriately modest sidewall appearance.
For an owner restoring an AMI, that means getting the construction type right matters just as much as getting the width and wheel diameter right. A tire that visually overwhelms the car or departs from its narrow radial character can change both stance and authenticity. For concours-level work, a Citroen club or French-car specialist can help confirm market-specific details beyond the basic size and construction.
Does correct tire fitment matter for showing a 1964 Citroen?
Yes, correct tire fitment matters on a 1964 Citroen because judges and knowledgeable enthusiasts notice size, construction, and overall sidewall appearance. On an AMI, a proper narrow radial in 135R15 supports the car's original look, while on a DS or ID the presence of the correct metric-wheel tire format is part of what makes the car recognizably correct. Even when the car is not being judged formally, these details affect authenticity.
The practical implication is that a tire should suit the model's original engineering rather than simply fill the wheel opening. On unusual European cars, wheel standard and tire format can be as important as brand choice. If you plan to show the car, review event rules and marque-club guidance early, since some venues are stricter than others about construction type and appearance.
What is the difference between Michelin X M+S 89 and Michelin ZX for the 1964 Citroen AMI?
For the 1964 Citroen AMI in 135R15, Michelin X M+S 89 and Michelin ZX are both blackwall radial options from the same brand family, but they differ in sidewall code detail and supporting specifications. The X M+S 89 is marked 135R15 72Q TL at 12 pounds, while the ZX is marked 135SR15 72S TL, also at 12 pounds, with a stated rim-width range of 3.50 to 4.50 inches.
That difference matters most to owners who care about period appearance and exact sidewall presentation. Both keep the AMI in a narrow radial format, but the tread family and speed symbol are not identical. If authenticity is your main goal, compare the sidewall wording and visual style against period photos or club guidance; if road use matters more, include the speed symbol and wheel-width guidance in the decision.
Safety & Road Use
Are 1964 Citroen tires safe for highway driving?
1964 Citroen AMI tires in 135R15 include radial products with speed symbols such as Q and S, which correspond to 99 mph and 112 mph ceilings respectively. That is comfortably above normal highway speeds when the tire is in good condition and used within its intended load and pressure range. On a vintage Citroen, the car's own age, braking system, suspension condition, and overall mechanical health usually matter at least as much as the tire's speed symbol in ordinary highway use.
Safety on the road comes down to the complete package, not just the sidewall code. A fresh, correctly sized radial on sound wheels is only one part of making a 1964 Citroen comfortable at speed. Before regular highway use, confirm the age of the tires, inspect the wheels, and make sure the rest of the car is sorted to the same standard as the tire choice.
What inflation pressure should I use for 1964 Citroen tires?
Inflation pressure on a 1964 Citroen should follow the factory vehicle recommendation first, with the tire maker's rated pressure and load figure used as a limit rather than as a blanket setting. For one 135R15 option, Firestone specifies a maximum load of 780 pounds at 44 psi. That figure belongs to that product and size only and should not be transferred to another tire or to the DS and ID metric fitment.
The best approach is to compare the car's handbook recommendation with the exact tire's sidewall information and use the tire within its intended operating range. Vintage Citroens can be sensitive to tire pressures because of their light front ends or, in the case of larger models, unusual suspension behavior. Using one pressure for every tire simply because the sizes look similar is not a good practice.
What should I check before taking a 1964 Citroen on a longer drive?
Before a longer drive in a 1964 Citroen, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, and check that the spare is serviceable as well. Look closely at the valve stems, especially if the wheel and tire combination may involve tubes or older hardware. On cars with uncommon wheel standards such as the DS and ID, verify that the wheels and tire sizes still match correctly.
That tire inspection should be part of a wider pre-drive routine suited to a vintage French car. Wheel fasteners, brakes, fluids, steering response, and lighting all deserve attention before a sustained trip. A 1964 Citroen can be a wonderfully capable road car, but the confidence comes from confirming that the whole car is ready, not from assuming the tires alone make it so.
