The 1964 Peugeot 403 comes from a period when Peugeot sedans and wagons were prized for durability, sensible engineering, and a distinctly European road feel. That makes tire choice especially important, because the car can be set up either with a 185R15 radial or a 6.50-15 bias-ply on the same 15-inch rim. Owners can lean toward a more traditional driving presentation with bias-ply construction or stay with the radial format that suits the 403’s practical touring character. Available 185R15 choices also open the door to different sidewall treatments and tire series. The right decision starts with the construction and appearance that best match the car’s condition, restoration direction, and intended use.
Which Tire Size Is Right for The 1964 Peugeot 403
The 1964 Peugeot 403 uses two primary tire sizes, and the first step is deciding whether your car is set up for radial or bias-ply construction. Both sizes fit a 15-inch rim, and the Sedan & Wagon sub-model uses either format, so the real choice is less about trim level and more about wheel setup, desired driving character, and the kind of appearance you want the car to carry.
185R15 is a Euro-metric radial size in which 185 refers to nominal section width in millimeters, R indicates radial construction, and 15 is the rim diameter in inches. On a 1964 Peugeot 403, this size reflects the car’s European radial fitment character and keeps the focus on a more road-oriented touring setup. Available options include Coker Classic, Michelin, Avon, and Universal Vintage Tire, with Blackwall, Redline, and Narrow Whitewall treatments across series such as Michelin XVS, Turbosteel CR3B, and Universal Sport. This size is the natural place to start if radial construction is already part of the car’s setup or if period-style radial appearance matters.
6.50-15 is a numeric bias-ply size in which 6.50 represents nominal section width in inches and 15 identifies the wheel diameter. For the 1964 Peugeot 403, this size suits buyers who want to stay with a traditional bias-ply construction rather than move to a radial presentation. Bias-ply sizing also speaks a different language than modern metric tires, so it is important to match the tire to the actual wheel and vehicle setup rather than compare by width alone. This size deserves a closer look when restoration direction, original-style feel, or an existing bias-ply configuration guides the decision.
Fitment is straightforward for the covered 1964 Peugeot 403 sub-model, because the same two primary tire sizes appear across the Sedan & Wagon range. Checking the sub-model still matters so the tire choice stays aligned with the car’s current wheel setup and whether it is being kept in bias-ply or radial form.

Tire Size & Fitment
What tire size fits a 1964 Peugeot 403?
The 1964 Peugeot 403 uses two primary tire sizes: 185R15 in radial construction and 6.50-15 in bias-ply construction. Both are 15-inch fitments, so the choice is tied more to construction type and wheel setup than to a change in rim diameter.
That means the right tire starts with confirming how the car is currently configured. A 403 already running radial tires may be best evaluated around 185R15 choices, while a car kept in a traditional bias-ply setup points toward 6.50-15. It is also smart to confirm wheel width, overall tire clearance, and whether any suspension or wheel changes have been made over the years.
What size rim does a 1964 Peugeot 403 use?
The primary tire fitments for the 1964 Peugeot 403 both use a 15-inch rim diameter. That applies to the 185R15 radial size and the 6.50-15 bias-ply size, so the basic wheel diameter remains consistent even though the tire sizing systems are different.
A matching 15-inch diameter does not remove the need to verify the wheel itself. Collector cars are often changed over time, and wheel width can affect how a tire sits and performs. Before selecting between radial and bias-ply construction, check the actual wheels on the car and compare them with the rim-width guidance attached to the tire you are considering.
Does the 1964 Peugeot 403 Sedan & Wagon use the same tire size?
The 1964 Peugeot 403 Sedan & Wagon uses the same primary fitment options: 185R15 in radial form and 6.50-15 in bias-ply form. The sub-model does not introduce a separate size split here, so trim identification is less important than confirming the construction and wheel setup already on the vehicle.
That simplifies the search, but it does not make every tire choice identical. A wagon or sedan that has been converted to different wheels, fitted with older replacement tires, or restored with a particular appearance goal may point you toward one construction over the other. Looking at the car’s existing wheels and intended use will narrow the decision much faster than body style alone.
Choosing the Right Tire
What should I consider when choosing a 185R15 tire for a 1964 Peugeot 403?
Start with the basics: 185R15 is the radial size used on the 1964 Peugeot 403, and available choices vary by brand, tire series, sidewall treatment, rim-width specification, and construction details within the radial category. Blackwall, Redline, and Narrow Whitewall options all appear in this size.
The best comparison points are the ones that match how the car will actually be used. A restoration-oriented driver may focus on sidewall appearance first, while a road car may put more attention on wheel compatibility and overall product specifications. It also helps to confirm whether the car has stock-type wheels or a changed setup before narrowing the product grid.
What sidewall styles are available for 1964 Peugeot 403 tires?
In 185R15 radial fitment, the 1964 Peugeot 403 has several sidewall presentations available, including Blackwall, Redline, and Narrow Whitewall. Those choices can change the car’s visual character considerably, even when the tire size remains the same.
Sidewall style is mainly an appearance decision, but it should still be made within the correct size and wheel fitment. A buyer looking for a cleaner touring look may prefer Blackwall, while Redline or Narrow Whitewall can create a more distinctive period-style presentation. It is wise to settle the construction and fitment question first, then use sidewall style to refine the final look.
What brands offer tires for the 1964 Peugeot 403?
For 185R15 radial fitment on a 1964 Peugeot 403, available brands include Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those brands appear across different radial series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport.
Brand choice should be considered alongside the rest of the package rather than on name alone. Sidewall appearance, rim-width compatibility, load specification where stated, and the overall look you want on the 403 all matter. Comparing the tire series and visual treatment often tells you more about which option belongs on your car than the brand label by itself.
Restoration & Appearance
Which tire should I choose for a period-style 1964 Peugeot 403?
A period-style 1964 Peugeot 403 can point in two directions. A 6.50-15 bias-ply keeps the focus on a traditional construction, while a 185R15 radial stays within the car’s European-style radial sizing language and offers more visible variation in sidewall treatment.
The better choice depends on what kind of restoration story the car is telling. Some owners want the look and feel of an older bias-ply setup, while others want a radial tire that still preserves a vintage presentation. When exact originality matters, compare your choice against marque history, photos, and restoration references before settling on sidewall style or construction.
How does tire construction affect the appearance of a restored 1964 Peugeot 403?
Tire construction changes more than ride and response; it also changes the visual stance of a restored 1964 Peugeot 403. A bias-ply 6.50-15 gives the car a more traditional presentation, while a 185R15 radial places it in a distinctly European radial format with choices such as Blackwall, Redline, and Narrow Whitewall.
That makes construction part of the restoration decision, not just a technical one. Owners chasing a traditional look may begin with the bias-ply size, while those wanting a vintage touring appearance with more product variety may lean toward the radial size. It helps to evaluate the tire against the wheel design, ride height, and overall finish of the completed car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1964 Peugeot 403?
Yes, modifications can affect tire fitment on a 1964 Peugeot 403 even when the tire size itself is correct. Changes to wheel width, wheel offset, suspension height, steering components, or body clearance can alter how either a 185R15 radial or 6.50-15 bias-ply sits on the car.
That is why an older Peugeot should be checked as it exists today, not only by what the original fitment calls for. Aftermarket wheels, replacement springs, brake conversions, or bodywork can all change clearance. Measuring the actual wheel setup and inspecting turning and suspension travel helps avoid surprises once the new tires are mounted.
What should I inspect before driving a 1964 Peugeot 403 on new tires?
Before driving a 1964 Peugeot 403 on new tires, inspect the wheels for correct diameter and condition, confirm the tires are mounted in the intended size and construction, and check inflation pressure carefully. It is also important to look over valve stems, lug hardware, and the general condition of the suspension and steering.
A collector car that sits for long periods deserves an extra walk-around before any serious road use. Look for rubbing marks, uneven tire seating, fluid leaks near the brakes or shocks, and any sign that the car tracks or steers abnormally on the first short drive. Catching those issues early protects both the new tires and the car itself.
How should tires on a collector 1964 Peugeot 403 be maintained?
Tires on a collector 1964 Peugeot 403 should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Whether the car wears 185R15 radials or 6.50-15 bias-ply tires, low annual mileage does not prevent aging, so sidewalls, tread surfaces, and air retention still need attention.
Good maintenance also includes keeping the car away from prolonged sunlight, moisture, and ozone sources when stored. Periodically moving the car, checking for flat spotting, and inspecting for cracks, bulges, cuts, or irregular wear can reveal problems before they become road issues. A short inspection before each outing is especially worthwhile on vehicles that are driven infrequently.
