The 1968 Citroen SW comes from an era when Citroen wagons stood apart for their engineering, ride quality, and distinctly European approach to family and utility motoring. On a car like this, tire selection is closely tied to preserving the character that makes the wagon special on the road. The 1968 Citroen SW uses radial tire fitments in 180-380 and 185R15, both tied to the car’s original-style metric tire story. That opens the door to several period-style radial choices, including blackwall, narrow whitewall, and redline presentations. The key is deciding whether to stay closest to the millimetric format or move to the 15-inch equivalent after confirming wheel compatibility.
Which Tire Size Is Right for The 1968 Citroen SW
The 1968 Citroen SW uses two primary tire sizes, and both appear across the covered wagon sub-models. The first step is confirming whether the car still has its original millimetric wheel setup for 180-380 tires or has been changed to a 15-inch wheel for 185R15 tires. Once that is established, the decision becomes choosing the right radial tire style, brand, and presentation for the way the wagon is restored and driven.
180-380 is a classic metric radial size, with 180 indicating nominal section width in millimeters and 380 referring to the wheel diameter in millimeters rather than inches. For the 1968 Citroen SW, this format reflects the distinctive European tire sizing conventions that were part of the car’s period engineering. It is best understood as a specialized original-style fitment path rather than a common modern replacement format. This size matters most for owners keeping the wagon on its original millimetric wheel arrangement and wanting to preserve the car’s traditional fitment character.
185R15 is a Euro-metric radial size, with 185 showing nominal section width in millimeters, R indicating radial construction, and 15 identifying a 15-inch rim. On the 1968 Citroen SW, it serves as a 15-inch radial fitment path that opens up more visible product choice. Available options include Coker Classic, Michelin, Avon, and Universal Vintage Tire, with blackwall, narrow whitewall, and redline sidewall treatments across series such as Michelin XVS, Coker Classic Radial, Universal Sport, and Turbosteel CR3B. It is the practical size to evaluate when the wagon is already running 15-inch wheels or when a restoration uses that wheel format.
Tire fitment is straightforward across the covered 1968 Citroen SW wagon sub-models because both use the same two radial tire sizes. Checking the exact sub-model still helps confirm the vehicle identity, but the larger fitment question is whether the wagon has millimetric wheels or a 15-inch wheel setup.

Tire Size & Fitment
What tire size fits a 1968 Citroen SW?
The 1968 Citroen SW uses two radial tire sizes: 180-380 and 185R15. Both the SW 19 Wagon and SW 21 Wagon share those same fitment paths, so the main distinction is not sub-model but the wheel format installed on the car.
That means the first thing to verify is whether the wagon still has millimetric wheels for 180-380 tires or 15-inch wheels for 185R15 tires. Once the wheel setup is confirmed, the choice shifts toward brand, sidewall appearance, and how closely the tire suits the car’s restoration goals and intended road use.
What size rim does a 1968 Citroen SW use?
A 1968 Citroen SW can use a 15-inch rim with 185R15 tires. The other primary fitment, 180-380, is a millimetric tire size that corresponds to a wheel diameter expressed in millimeters rather than the familiar inch-based sizing used on most American cars.
Rim confirmation matters before ordering because a 380-millimeter wheel and a 15-inch wheel are not the same thing, even though they are close in general scale. Checking the wheel stamping, measuring carefully, and confirming the car’s current setup helps prevent choosing a tire size that does not match the wheel actually on the wagon.
Do all 1968 Citroen SW sub-models use the same tire size?
Yes. Both the 1968 Citroen SW 19 Wagon and the 1968 Citroen SW 21 Wagon use the same two tire-size paths: 180-380 and 185R15. In this case, sub-model choice does not create a separate tire-size split between the covered wagons.
That simplifies shopping, but it does not remove the need to inspect the car itself. Many surviving European wagons have seen wheel changes over time, so the practical question is whether the car remains on millimetric wheels or has been converted to a 15-inch setup that points you toward the available 185R15 radial choices.
Choosing the Right Tire
What should I consider when choosing a 185R15 tire for a 1968 Citroen SW?
Start with wheel compatibility, then compare the available 185R15 radial options by brand, tire series, sidewall style, and any stated rim-width or load details. For the 1968 Citroen SW, 185R15 choices include blackwall, narrow whitewall, and redline treatments across several vintage-oriented radial lines.
The right choice depends on the wagon’s appearance goals and how it will be used. A restoration-minded owner may focus on a traditional sidewall presentation, while a regular road-use owner may pay closer attention to rim-width range, load information where stated, and whether the tire’s visual style complements the car without straying from its period feel.
What sidewall styles are available for 1968 Citroen SW tires?
For 185R15 fitment on the 1968 Citroen SW, available sidewall styles include blackwall, narrow whitewall, and redline. Those choices create a noticeable difference in presentation even when the tire size remains the same, especially on a European wagon with distinctive period styling.
Choosing among them comes down to the look you want the car to project. Blackwall usually gives the cleanest understated appearance, narrow whitewall adds a more formal vintage touch, and redline offers a sportier custom-leaning presentation. The important step is making sure the visual choice still sits within the correct size and wheel setup for the wagon.
What brands offer tires for the 1968 Citroen SW?
The available 185R15 radial options for the 1968 Citroen SW include products from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those brands appear across tire series such as Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport.
Brand choice should be treated as part of the overall specification decision rather than a ranking exercise. Compare the actual size, sidewall style, rim-width range where stated, and the kind of appearance each series brings to the car. That approach helps keep the focus on fitment and period-style presentation instead of brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1968 Citroen SW?
A period-style approach for a 1968 Citroen SW starts with using one of its proper radial size paths, either 180-380 or 185R15, depending on the wheels on the car. From there, the best match is usually the tire that preserves the wagon’s traditional European look without forcing a modernized appearance.
For many owners, that means focusing on the wheel format first and then selecting a sidewall treatment that suits the restoration theme. If exact originality matters beyond general period style, it is wise to compare the car against marque references, historical photos, and restoration documentation before settling on a specific sidewall or tire series.
How does tire construction affect the appearance of a restored 1968 Citroen SW?
On a 1968 Citroen SW, tire construction does not create a bias-ply versus radial debate because the primary fitments are radial. The visual difference instead comes more from size format and sidewall presentation, especially when comparing a millimetric-style fitment to a 15-inch radial choice with blackwall, narrow whitewall, or redline styling.
That makes tire appearance a matter of proportion and presentation rather than simply construction type. A wagon restored with close attention to its European character may look most convincing with a restrained sidewall treatment, while a more personalized car may lean toward redlines. The important thing is keeping the tire size appropriate to the wheel and overall stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1968 Citroen SW?
Yes. Modifications can affect tire fitment on a 1968 Citroen SW, especially if the wagon has been changed from its original wheel format or fitted with aftermarket wheels. A switch between millimetric wheels and 15-inch rims changes the tire-size path immediately and can also alter width and clearance considerations.
Suspension changes, ride-height alterations, and wheel-offset differences can also influence how a tire sits in the fender opening and how it behaves at full steering lock. Before choosing tires, inspect the actual wheel diameter on the car and look closely at inner clearance, outer clearance, and any signs that a previous owner changed the setup.
What should I inspect before driving a 1968 Citroen SW on new tires?
Before driving a 1968 Citroen SW on new tires, inspect the wheels for correct diameter and condition, make sure the tires are seated and inflated properly, and look over the suspension and steering for worn or loose components. It also helps to confirm that the tires clear the body and suspension throughout steering travel.
A collector wagon that sits for long periods deserves an especially careful once-over before regular road use. Check for fluid leaks that could reach the tires, verify even ride height, and watch for rubbing during the first short drive. Catching those issues early helps protect the new tires and keeps the car’s road manners more predictable.
How should tires on a collector 1968 Citroen SW be maintained?
Tires on a collector 1968 Citroen SW should be maintained with regular pressure checks, visual inspection for cracking, bulges, cuts, and uneven wear, and periodic review of how the car is sitting during storage. Even a low-mileage wagon can develop tire concerns simply from age, inactivity, or poor storage conditions.
Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve the sidewalls and overall casing condition. It is also smart to inspect the tires before every meaningful drive rather than relying on appearance alone. A vintage vehicle can spend months parked, so condition checks matter just as much as mileage.
