The 1963 Peugeot 403 represents the practical, durable side of postwar French motoring, a sedan and wagon platform known for its understated styling and everyday usability. For collectors today, tire choice plays a big role in preserving that character while matching the car’s intended road manners. This Peugeot 403 uses either a 185R15 radial or a 6.50-15 bias-ply tire, both on 15-inch rims. That opens the door to traditional bias-ply fitment or period-flavored radial options in blackwall, redline, and narrow whitewall styles from brands such as Michelin, Avon, Coker Classic, and Universal Vintage Tire. The right choice depends on whether appearance, driving feel, or restoration direction matters most.
Which Tire Size Is Right for The 1963 Peugeot 403
The 1963 Peugeot 403 uses two primary tire sizes, and the decision is less about rim diameter than about construction and presentation, since both fit a 15-inch wheel. Sedan & Wagon applications can use either 185R15 radial or 6.50-15 bias-ply sizing, so the first step is deciding whether to stay with a traditional bias-ply setup or move to a radial that keeps a vintage look.
185R15 is a Euro-metric radial size in which 185 identifies the nominal section width in millimeters, R designates radial construction, and 15 is the wheel diameter in inches. On a 1963 Peugeot 403, this size offers a more modern radial format while remaining visually appropriate for a vintage European sedan or wagon. Available choices include blackwall, redline, and narrow whitewall treatments across series such as Michelin XVS, Coker Classic Radial, Universal Sport, and Avon Turbosteel CR3B. It is the size to evaluate if road use and radial construction are part of the plan, while still checking wheel width and overall clearance.
6.50-15 is a numeric bias-ply size in which 6.50 indicates the nominal section width in inches and 15 identifies the rim diameter. That construction gives the 1963 Peugeot 403 a more traditional period-style tire format, which can matter for restoration-minded owners who want to retain an earlier look and feel. Bias-ply sizing also reflects the vintage tire language many mid-century cars were originally associated with. This size deserves consideration when maintaining a more traditional presentation is more important than moving to a radial-style alternative.
Fitment is straightforward across the covered 1963 Peugeot 403 sub-model range because the same two tire sizes apply to the Sedan & Wagon configuration. The key choice is not between different trims, but between radial and bias-ply construction on the same 15-inch rim diameter.

1963 Peugeot 403 Sedan & Wagon
The 1963 Peugeot 403 Sedan & Wagon uses the same 185R15 radial and 6.50-15 bias-ply tire options. That makes selection more about construction type, sidewall appearance, and wheel compatibility than about sorting through different sub-model-specific size requirements.
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.
Best 1963 Peugeot 403 Tires for Sale

The product grid gives useful variation in tire series and sidewall style, including blackwall, redline, and narrow whitewall options, along with differing rim-width specifications.
These 1963 Peugeot 403 tire FAQs focus on the two primary sizes, 15-inch rim fitment, bias-ply versus radial selection, appearance choices, and the wheel and clearance checks worth making before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 1963 Peugeot 403?
The 1963 Peugeot 403 uses two primary tire sizes: 185R15 in radial construction and 6.50-15 in bias-ply construction. Both sizes apply to the Peugeot 403 Sedan & Wagon and both are built around a 15-inch wheel diameter.
That means the real choice is not identifying a different trim-specific size, but deciding which construction best matches the car’s intended use and appearance. A radial like 185R15 suits owners who want a vintage European radial format, while 6.50-15 is the traditional bias-ply option. Before choosing, confirm the actual wheel width and check for any modifications that may affect clearance.
What size rim does a 1963 Peugeot 403 use?
The 1963 Peugeot 403 uses a 15-inch rim diameter. Both primary tire sizes associated with the car, 185R15 and 6.50-15, are built for a 15-inch wheel.
Rim diameter is only part of the fitment picture on an older Peugeot. The wheel’s actual width still matters, especially when comparing radial options that carry different rim-width ranges within the available products. It is also smart to confirm that the car still has its intended wheels, since collector cars are sometimes fitted with replacements that change how a tire sits or clears.
What does 6.50-15 mean on a 1963 Peugeot 403?
On a 1963 Peugeot 403, 6.50-15 is a numeric bias-ply size. The 6.50 refers to the tire’s nominal section width in inches, and the 15 identifies the wheel diameter in inches.
This older sizing format is useful to understand because it points to a traditional bias-ply fitment rather than a modern metric radial code. Buyers considering 6.50-15 usually do so for a period-style presentation and vintage driving character. Since both 6.50-15 and 185R15 use the same rim diameter, the next step is comparing construction style, wheel width, and the car’s intended use.
Bias-Ply & Radial Options
Is 6.50-15 a bias-ply or radial tire for the 1963 Peugeot 403?
For the 1963 Peugeot 403, 6.50-15 is a bias-ply tire size. It uses the older numeric bias-ply sizing format and serves as the traditional construction option alongside the radial 185R15 fitment.
That distinction matters because bias-ply and radial tires differ in both appearance and driving feel. Owners choosing 6.50-15 are often aiming for a more period-style presentation, while 185R15 shifts the car toward a radial format. When comparing the two, verify wheel width, inspect suspension and steering condition, and make sure the tire choice matches how the car will actually be driven.
Should I use bias-ply or radial tires on a 1963 Peugeot 403?
A 1963 Peugeot 403 can be set up with either 6.50-15 bias-ply tires or 185R15 radial tires. The choice depends on whether the priority is a more traditional vintage presentation or a radial-format tire in the correct 15-inch diameter.
Bias-ply appeals to restoration-minded owners who want an older tire look and construction style, while 185R15 opens up radial choices in blackwall, redline, and narrow whitewall designs. The decision should also reflect the actual wheels on the car and how it will be used. A Peugeot that sees regular road miles deserves careful wheel-width and clearance verification before changing construction types.
What should I check before converting my 1963 Peugeot 403 from bias-ply to radial tires?
The main checks before moving a 1963 Peugeot 403 from 6.50-15 bias-ply to 185R15 radial tires are wheel diameter, wheel width, and overall clearance. Both sizes use a 15-inch rim, but the wheel still needs to suit the radial tire being considered.
A careful conversion also includes looking at fender clearance, steering travel, suspension condition, and the car’s general alignment and ride-height setup. Older vehicles can respond differently when tire construction changes, especially if the wheels are not original. It is worth measuring the actual wheel width and comparing it to the radial product’s rim-width specification before making the switch.
Choosing the Right Tire
What should I consider when choosing a 185R15 tire for a 1963 Peugeot 403?
Choosing a 185R15 tire for a 1963 Peugeot 403 starts with confirming that radial construction matches the car’s intended use and that the 15-inch wheel is suitable for the specific product. Within this size, available options vary by brand, tire series, sidewall style, rim-width range, and in some cases load or speed-related specifications.
Once the size is settled, the decision becomes more about the character of the tire. A blackwall presentation keeps things understated, while redline or narrow whitewall treatments create a more stylized vintage look. Buyers should also compare the wheel-width requirements of the exact tire under consideration, since not every 185R15 radial in the group is built around the same rim-width range.
What sidewall styles are available for 1963 Peugeot 403 tires?
For the 1963 Peugeot 403, available 185R15 radial products include blackwall, redline, and narrow whitewall sidewall styles. Those choices allow the car to lean toward a restrained European look or a more customized vintage presentation without changing the basic tire size.
Sidewall style is mostly an appearance decision, but it can strongly influence how the finished car reads visually. A blackwall generally feels closest to a simple, utilitarian presentation, while redline and narrow whitewall add more period flavor. The smartest way to choose is to match the sidewall to the restoration theme, wheel style, and the way the Peugeot will actually be shown or driven.
What brands offer tires for the 1963 Peugeot 403?
The 1963 Peugeot 403 has 185R15 radial tire options from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those brands cover several different tire series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport.
Brand choice should be part of a broader comparison rather than the only deciding factor. It helps to look at sidewall style, tire series, wheel-width compatibility, and any load-related details that matter to the car’s use. Since the Peugeot can also use a 6.50-15 bias-ply size, some owners may first need to decide on construction before narrowing the field among the radial brands.
Restoration & Appearance
Which tire should I choose for a period-style 1963 Peugeot 403?
A period-style 1963 Peugeot 403 can point in two different directions depending on the look being pursued. The 6.50-15 bias-ply size gives the car a more traditional vintage tire format, while 185R15 keeps the fitment in a classic European radial size that still suits the era.
The better choice depends on whether the goal is a restoration-oriented presentation, a road-driven vintage car, or something in between. Sidewall treatment also matters, since blackwall, redline, and narrow whitewall options can change the car’s visual character. When exact originality is important, compare the tire choice against marque references and period vehicle documentation before making the final decision.
How does tire construction affect the appearance of a restored 1963 Peugeot 403?
Tire construction changes the visual stance of a restored 1963 Peugeot 403 even when the wheel diameter stays at 15 inches. A 6.50-15 bias-ply setup gives the car a more traditional vintage presentation, while 185R15 brings in the look of a classic radial-size European touring tire.
That visual difference can be subtle or significant depending on the wheels, ride height, and sidewall style chosen. Blackwalls keep the car restrained, while redline or narrow whitewall options introduce more personality. For a restoration-oriented build, construction should be selected alongside the intended appearance rather than treated as a purely technical decision made after the fact.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1963 Peugeot 403?
Yes, modifications can affect tire fitment on a 1963 Peugeot 403 even when the tire size itself is correct. Changes to wheels, suspension height, steering components, or body clearance can alter how either 185R15 or 6.50-15 sits on the car.
That is especially important on older vehicles that may have had replacement wheels installed over the years. A different wheel width can matter with radial products, and any ride-height or suspension change can influence clearance at the fender and during full steering travel. Before mounting new tires, inspect the actual setup on the car rather than assuming it still matches stock dimensions.
What should I inspect before driving a 1963 Peugeot 403 on new tires?
Before driving a 1963 Peugeot 403 on new tires, inspect the wheels for correct diameter and condition, make sure the tires are seated properly, and confirm there is no interference at the fenders or steering components. Tire pressure should also be set appropriately for the chosen tire.
A broader pre-drive check is worthwhile on any collector Peugeot. Look over the suspension, steering, and brakes, and then recheck the tires after a short initial drive for any signs of rubbing, air loss, or unusual wear. Older cars often reveal clearance or alignment issues only once they are back on the road and carrying weight through corners and turns.
How should tires on a collector 1963 Peugeot 403 be maintained?
Tires on a collector 1963 Peugeot 403 should be maintained with regular pressure checks, visual inspections, and periodic checks for cracking, cuts, bulges, or uneven wear. That applies whether the car is running 185R15 radials or 6.50-15 bias-ply tires.
Low-mileage storage does not remove the need for maintenance, since age and environment can affect a tire even when tread still looks fresh. Keep the car stored away from prolonged sunlight, heat, moisture, and ozone sources when possible, and inspect the tires before any longer outing. A vintage Peugeot that sits often should have its tires examined more carefully, not less.
