The 1972 Citroen SW comes from an era when Citroen wagons were prized for combining European road manners, long-distance comfort, and distinctive design in a highly practical package. On a collector car like this, tire choice affects not only stance and appearance, but also the character the car brings to the road. This model uses 180R15 and 185R15 radial tire sizes on 15-inch rims, so the key decision is confirming which size is already on the car and which best suits its wheel setup. Available choices include blackwall, narrow whitewall, and redline sidewall styles across several radial series. That makes it important to balance fitment, presentation, and intended use before choosing.
Which Tire Size Is Right for The 1972 Citroen SW
The 1972 Citroen SW uses two primary tire sizes, 180R15 and 185R15, and both are radial tires built for 15-inch rims. Both the 19 Wagon and 21 Wagon are associated with these sizes, so the first step is confirming the wheel setup already on the car and whether a narrower or slightly wider metric radial best matches its current fitment and restoration goals.
180R15 is a Euro-metric radial size in which 180 refers to the nominal section width in millimeters, R identifies radial construction, and 15 is the wheel diameter in inches. This format is commonly understood as an older metric radial sizing style and suits the Citroen SW's period road-car character. In this size, Michelin XAS options are available in blackwall and narrow whitewall form, with differing rim-width ranges that matter when matching the tire to the wheel already on the car. It is a useful choice for owners focused on traditional European radial presentation and careful wheel compatibility.
185R15 is also a Euro-metric radial size, with a nominal 185-millimeter section width, radial construction, and a 15-inch rim diameter. On the 1972 Citroen SW, it represents a slightly broader metric radial fitment choice while staying within the car's correct 15-inch wheel diameter. Product selection is wider here, including Michelin, Avon, Coker Classic, and Universal Vintage Tire offerings in blackwall, narrow whitewall, and redline styles across several tire series. This size gives buyers more freedom to weigh appearance, brand preference, and wheel-width suitability while keeping to a period-appropriate radial format.
Fitment is straightforward across the covered 1972 Citroen SW sub-models because both the 19 Wagon and 21 Wagon are associated with the same two radial tire sizes. Checking the exact sub-model still helps keep the search organized, but wheel setup and current tire size are the more important details to confirm before selecting a replacement.

1972 Citroen SW 19 Wagon
The 1972 Citroen SW 19 Wagon is associated with both 180R15 and 185R15 radial tires on 15-inch wheels. That means the practical choice is less about trim-specific fitment and more about confirming which size is already fitted, along with the sidewall style and tire series that suit the car's intended look and road use.
The 1972 Citroen SW 21 Wagon also uses the same 180R15 and 185R15 radial tire fitment pattern. Tire selection comes down to verifying the wheel and current size first, then choosing among the available radial options based on appearance, brand preference, and how closely the car is being kept to a restoration-oriented presentation.
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.

Common 1972 Citroen SW tire questions usually come down to choosing between 180R15 and 185R15, confirming 15-inch rim fitment, comparing sidewall and brand options, and checking wheel condition, clearance, and tire age before regular road use.
Tire Size & Fitment
What tire size fits a 1972 Citroen SW?
The 1972 Citroen SW uses two primary tire sizes: 180R15 and 185R15. Both are radial tires designed for 15-inch rims, and both the 19 Wagon and 21 Wagon are associated with those same two sizes rather than having separate sub-model-only fitments.
That makes the next step confirming what is actually on the car now, especially if the wheels have ever been changed or the car has been restored previously. Since both sizes are valid for this model, checking the current wheel width, present tire size, and available clearance will help narrow the decision before choosing among the available radial products.
What size rim does a 1972 Citroen SW use?
The 1972 Citroen SW uses a 15-inch rim diameter with both of its primary tire sizes, 180R15 and 185R15. Even though the two tire sizes differ slightly in width, they share the same basic wheel diameter, so the first number to verify is not the diameter but the actual wheel width already on the car.
That matters because individual tire options within these sizes can have different recommended rim-width ranges. A car that still has its original-style wheels may point you toward one product range, while an SW with later wheels may suit another. Verifying the wheel before ordering helps avoid choosing a tire whose profile does not match the rim properly.
Do all 1972 Citroen SW sub-models use the same tire size?
Yes. The 1972 Citroen SW 19 Wagon and 21 Wagon are both associated with the same two tire sizes, 180R15 and 185R15, and both use radial construction on 15-inch rims. There is no separate tire-size split here between the covered sub-models.
Since the fitment pattern is shared, the deciding factor is usually the wheel and tire setup on the specific car rather than the wagon designation itself. Looking at the tire already mounted, measuring the wheel width if needed, and checking body and suspension clearance will do more to guide the choice than the sub-model name alone.
Choosing the Right Tire
What should I consider when choosing a 1972 Citroen SW tire?
Start by confirming whether the car is set up for 180R15 or 185R15, since both sizes are used on the 1972 Citroen SW. From there, compare radial construction details such as rim-width suitability, sidewall style, tire series, and any load figure shown for the product you are considering.
The best choice depends on how the car is used and how you want it to look. A restoration-oriented owner may lean toward a traditional blackwall or narrow whitewall presentation, while another may prefer a redline treatment. Matching the tire to the wheel and the car's overall presentation matters more than simply picking the most familiar brand name.
What sidewall styles are available for 1972 Citroen SW tires?
1972 Citroen SW tires are available in several sidewall styles, including blackwall, narrow whitewall, and redline. The exact style depends on tire size and series, with blackwall appearing across both 180R15 and 185R15, while narrow whitewall and redline are found in selected applications.
Sidewall choice is mostly an appearance decision once the correct tire size and wheel compatibility are established. A narrow whitewall can give the wagon a refined period-style look, while blackwall stays understated and redline adds a sportier visual accent. It helps to decide early whether the goal is subtle restoration presentation or a more personalized vintage look.
What brands offer tires for the 1972 Citroen SW?
Tires for the 1972 Citroen SW are available from Michelin, Avon, Coker Classic, and Universal Vintage Tire. Michelin appears in both 180R15 and 185R15 applications, while Avon, Coker Classic, and Universal Vintage Tire are represented in 185R15 options.
Brand is only one part of the decision. It is worth comparing each option by tire series, sidewall treatment, and wheel compatibility rather than assuming every tire in the same size serves the same purpose. For this car, the stronger buying comparison is often Michelin XAS or XVS styling versus Coker Classic, Universal Sport, or Avon visual and fitment characteristics.
Restoration & Appearance
Which tire should I choose for a period-style 1972 Citroen SW?
A period-style 1972 Citroen SW tire choice usually starts with the correct metric radial format in either 180R15 or 185R15, depending on the wheel setup already on the car. Within those sizes, Michelin XAS and XVS series, along with other classic-style radial offerings, keep the car in an era-appropriate visual and functional range.
Appearance should be balanced with the actual wheel dimensions and the way the car will be driven. Blackwall often gives the cleanest traditional European look, while narrow whitewall can suit a more formal restoration presentation. When exact originality matters, marque-specific historical references are the right place to confirm brand and sidewall details beyond basic fitment.
How does tire construction affect the appearance of a restored 1972 Citroen SW?
On the 1972 Citroen SW, construction is less of a bias-ply-versus-radial question because the primary fitments are already radial. The visual difference comes more from the specific radial series and sidewall treatment, such as blackwall, narrow whitewall, or redline, than from a construction change between old and new tire types.
That still matters on a restored car because the tire sidewall is a large part of the finished look. A subtle blackwall can preserve a clean European character, while a narrow whitewall shifts the presentation in a more formal direction. Choosing the right radial style helps the wagon look cohesive without forcing a tire choice that conflicts with wheel fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1972 Citroen SW?
Yes. A 1972 Citroen SW can be affected by aftermarket wheels, changes in wheel width, suspension alterations, or body modifications just like any other collector vehicle. Even when the tire size remains 180R15 or 185R15, a different wheel setup can change how the tire sits and whether it has adequate operating clearance.
That is why the actual car should be checked before settling on a tire, especially if its history is not fully known. Wheel diameter, wheel width, and available clearance at steering and suspension movement are the most important points to verify. A proper measurement is more useful than relying on what should be on the car in theory.
What should I inspect before driving a 1972 Citroen SW on new tires?
Before driving a 1972 Citroen SW on new tires, inspect the wheels, valve stems, and overall wheel condition, then confirm that the tire size matches the intended setup. It also helps to look over suspension and steering components so the new tires are not being asked to compensate for worn parts elsewhere on the car.
After installation, check inflation, watch for any rubbing during full steering movement, and recheck the tires after the first few drives. Collector cars that sit for long periods benefit from extra attention to air retention and visible sidewall condition. A quick walkaround before use often catches issues early, especially on a wagon meant for occasional touring.
How should 180R15 or 185R15 tires on a collector 1972 Citroen SW be maintained?
180R15 and 185R15 tires on a collector 1972 Citroen SW should be maintained with regular pressure checks, visual inspections, and careful storage habits. Look for cracking, bulges, cuts, uneven wear, or slow air loss, especially if the wagon sees intermittent use rather than frequent driving.
Storage conditions matter as much as mileage on many collector vehicles. Keeping the car away from prolonged sunlight, excess moisture, and ozone sources can help preserve tire condition over time. It is also smart to inspect the tires before any longer trip, since a low-use car can develop age-related tire issues even when the tread still looks serviceable.
