1960 Peugeot 403 Tires

The 1960 Peugeot 403 uses two primary tire sizes: 185R15 in radial construction and 6.50-15 in bias-ply construction. Both are tied to a 15-inch rim, and both apply to the covered Sedan & Wagon configuration.

That means the main question is not simply size, but which construction matches the car’s current setup and your goals for appearance and road use. A car still configured around traditional bias-ply tires may lead you one direction, while a 403 already running radial-compatible tires may point toward 185R15. Wheel width, clearance, and the actual tires already on the car should all be checked before making the switch.

The 1960 Peugeot 403 uses a 15-inch rim with both of its primary tire sizes. That applies whether the car is fitted with the 185R15 radial size or the 6.50-15 bias-ply size.

Knowing rim diameter answers only part of the fitment question, because width and overall wheel design still matter when choosing a tire. Some 185R15 radial products are built around different approved rim-width ranges, so it is smart to measure the wheels on the car rather than rely on assumption. That is especially important if the Peugeot has replacement wheels or if its current tires do not match one of the two established primary fitments.

6.50-15 is a vintage numeric bias-ply tire size. The 6.50 refers to nominal section width in inches, and the 15 refers to the wheel diameter, so this is a bias-ply tire intended for a 15-inch rim on the 1960 Peugeot 403.

For a buyer, the practical takeaway is that this size belongs to an older tire-sizing system and should not be read the same way as a modern metric radial. If your goal is a traditional mid-century presentation or you want to stay with bias-ply construction, 6.50-15 is the relevant fitment to evaluate. It is still important to confirm the wheel setup and compare the car’s existing tire and wheel combination before replacement.

On the 1960 Peugeot 403, 6.50-15 is the bias-ply primary tire size. The other primary fitment associated with this model is 185R15, which is a radial size, so the car is one of those vintage applications where both constructions appear in the fitment picture.

That distinction matters because construction affects both appearance and the way the tire relates to the wheel setup. A buyer choosing 6.50-15 is usually preserving a more traditional presentation, while 185R15 moves into radial territory without changing the 15-inch rim diameter. Before changing from one construction to the other, confirm wheel width, overall tire dimensions, and clearances rather than assuming the car is still configured exactly as it left decades ago.

Either can be appropriate for a 1960 Peugeot 403, because both a 6.50-15 bias-ply and a 185R15 radial are associated with the model. The better choice depends on whether your priority is a more traditional period-style setup or a radial fitment that keeps the car in a correct 15-inch wheel format.

A bias-ply choice usually appeals to restoration-minded owners who want an older visual and mechanical character, while a radial choice often suits owners focused on road use and broader product variety. The decision should not be made by appearance alone, though. The wheels on the car, any previous modifications, and the tire-to-body and tire-to-suspension clearances should all be verified before settling on one construction.

Start by confirming that the radial size under consideration is 185R15, since that is the radial primary fitment associated with the 1960 Peugeot 403. Then verify that the car still has 15-inch wheels in a width suitable for the radial tire you are considering, because approved rim-width ranges vary by product.

After wheel compatibility, compare the actual space available around the fenders, steering components, and suspension rather than assuming every older car is unchanged. Cars that have been restored, repaired, or modified may not sit exactly the same side to side. It also helps to inspect the current wheel and tire combination for signs of rubbing, unusual wear, or mismatched parts before making the conversion from a 6.50-15 bias-ply setup.

Begin with the basics: the tire needs to be a true 185R15 radial for a 15-inch rim, and the wheel width on the car should fall within the approved range for the specific product. In this size, the 1960 Peugeot 403 has choices from Coker Classic, Michelin, Avon, and Universal Vintage Tire.

Once fitment is confirmed, selection comes down to the kind of presentation and specification you want. Some 185R15 options are blackwall, while others are offered in redline or narrow whitewall form, and they also differ by tire series and certain specification details such as weight and maximum load figures where stated. Matching the tire to the car’s intended use and visual style usually leads to a better decision than choosing by brand name alone.

For the 1960 Peugeot 403, the available 185R15 radial options include blackwall, redline, and narrow whitewall sidewall styles. Those treatments appear across several brands and series, giving the car a noticeably different visual character without changing the core radial tire size.

Sidewall style is one of the most visible choices on a vintage Peugeot, so it should be matched to the way the car is restored or presented. A blackwall usually gives the most restrained look, while a narrow whitewall or redline adds a stronger period-style accent. Appearance should still come after fitment, though, so confirm the correct size, wheel compatibility, and construction before narrowing the decision to sidewall treatment.

The 185R15 radial size for the 1960 Peugeot 403 is available from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those options span multiple tire series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport.

Brand choice is useful, but it should be considered alongside the rest of the tire’s character. Some options differ by sidewall style, some by approved rim-width range, and some by details such as load or weight specifications where those are stated. The smartest comparison starts with the exact size and wheel setup on the car, then looks at which brand and series best support the desired appearance and driving use.

A period-style 1960 Peugeot 403 can point in two directions depending on your restoration goal. The 6.50-15 bias-ply size supports a more traditional vintage presentation, while the 185R15 radial keeps the car in a long-established European-style radial format on the same 15-inch rim diameter.

The better choice depends on whether you are trying to preserve an older driving and visual character or whether you want a radial tire that still looks appropriate on the car. Sidewall treatment matters as well, since blackwall, redline, and narrow whitewall options can change the car’s appearance noticeably. When exact originality is important, marque references and vehicle-specific historical documentation remain the best final check.

Tire construction can change the overall presentation of a restored 1960 Peugeot 403 even when wheel diameter stays the same. A 6.50-15 bias-ply gives the car a more traditional vintage look, while a 185R15 radial tends to move the visual impression toward a later, more modernized road-going setup.

That does not mean one is automatically more correct than the other for every restoration. Much depends on how the car is being finished, how closely the owner is following period references, and whether road use or visual authenticity carries more weight. Sidewall styling can further shape the result, so it helps to evaluate construction and sidewall treatment together instead of treating them as separate appearance decisions.

Yes. Even though the 1960 Peugeot 403 uses 15-inch tire fitments, changes such as aftermarket wheels, suspension work, ride-height changes, brake conversions, or body repairs can alter the space available for the tire and the wheel dimensions it needs.

That is why an older Peugeot should be measured as it sits today rather than judged only by model-year fitment. Check wheel diameter and width, inspect clearance at full steering lock, and look for any signs that the current tires have rubbed or sat unevenly. Small changes made over decades of service can affect whether a 185R15 radial or 6.50-15 bias-ply remains the better choice on the individual car.

Before road use, inspect the wheels for damage or corrosion, confirm that the tire size matches the intended setup, and make sure the tires are mounted and inflated properly. It also helps to examine the suspension and steering components so the new tires are not being asked to compensate for underlying mechanical issues.

A collector-era Peugeot can spend long periods parked, so the rest of the car deserves attention as much as the tires do. Look for interference marks inside the wheelhouses, verify that lug hardware and wheel seating surfaces are in good condition, and recheck pressure after the first few drives. Watching for uneven wear, pull, vibration, or air loss early can prevent a small fitment or mechanical problem from becoming a larger one.

Tires on a collector 1960 Peugeot 403 should be kept properly inflated, inspected regularly, and protected from long periods of harsh storage conditions. Even when tread wear is low, age-related issues such as cracking, flat spotting, air loss, bulges, or cuts can matter on a car that is driven only occasionally.

Good maintenance also means paying attention to the vehicle around the tires. Alignment, suspension condition, and brake drag can all shorten tire life or create misleading wear patterns. During storage, keeping the car away from prolonged sunlight, moisture, and ozone sources is helpful, and rolling or driving it periodically can reduce prolonged stress in one contact area. A short inspection before each drive is a smart habit with any vintage Peugeot.
