The 1959 Peugeot 403 comes from the period when European family cars were gaining a reputation for durable road manners, tidy proportions, and everyday practicality with a distinctly continental character. Whether kept as a sedan or wagon, the 403 appeals to owners who value authenticity and drivability in equal measure. Tire choice reflects that split, because this model is associated with both a 185R15 radial and a 6.50-15 bias-ply on 15-inch wheels. That opens the door to different brands, sidewall treatments, and period-style presentations. The real decision is matching the car’s current wheel setup and restoration goals to the right construction and appearance.
Which Tire Size Is Right for The 1959 Peugeot 403
The 1959 Peugeot 403 uses two primary tire sizes, and both mount on 15-inch rims. One is a 185R15 radial and the other is a 6.50-15 bias-ply, so the first step is confirming which construction and wheel setup the car is wearing now before narrowing the choice by brand, sidewall style, and overall appearance.
185R15 is a Euro-metric radial size in which 185 indicates the nominal section width in millimeters, R identifies radial construction, and 15 is the wheel diameter in inches. On a 1959 Peugeot 403, this size suits owners looking for the radial fitment associated with the car while keeping the proper 15-inch wheel diameter. Available choices include Blackwall, Narrow Whitewall, and Redline presentations from brands such as Michelin, Coker Classic, Avon, and Universal Vintage Tire. It is the size to evaluate when road use, radial construction, and period-minded appearance all need to be balanced carefully.
6.50-15 is a numeric bias-ply size in which 6.50 refers to the nominal section width in inches and 15 identifies the wheel diameter. That traditional sizing convention places it firmly in the period of the 1959 Peugeot 403 and makes it the natural starting point for owners who want a more vintage construction style. Bias-ply selection is often driven by restoration character and the way the tire fills out the car visually on its original-type wheel diameter. Before choosing it, confirm that the car has not already been converted to a radial-oriented wheel and suspension setup.
Fitment is straightforward across the covered 1959 Peugeot 403 sub-model range, because the same two primary tire sizes appear for the Sedan & Wagon. Checking the sub-model still matters, but the bigger decision here is construction choice rather than a separate size by body style.

1959 Peugeot 403 Sedan & Wagon
The 1959 Peugeot 403 Sedan & Wagon is associated with both the 185R15 radial and the 6.50-15 bias-ply on 15-inch rims. That gives owners room to choose between a more traditional bias-ply presentation and a radial approach, while still confirming the actual wheel setup already on the car.
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 1959 Peugeot 403 Tires for Sale
Available 1959 Peugeot 403 tire choices center on 185R15 radials from Coker Classic, Michelin, Avon, and Universal Vintage Tire. The product grid gives buyers meaningful comparisons in tire series, sidewall style, construction details, and rim-width compatibility across Blackwall, Narrow Whitewall, and Redline options.
These 1959 Peugeot 403 tire FAQs focus on the two primary sizes, 15-inch rim fitment, radial versus bias-ply selection, appearance choices, and the checks that matter before putting a collector-era Peugeot back on the road.
Tire Size & Fitment
What tire size fits a 1959 Peugeot 403?
The 1959 Peugeot 403 is associated with two primary tire sizes: 185R15 in radial construction and 6.50-15 in bias-ply construction. Both sizes use a 15-inch rim, so the main fitment distinction is not wheel diameter but which construction type the car is set up to use.
That means the right choice starts with the car in front of you. A 403 that has remained close to a traditional period-style setup may be matched to the bias-ply size, while another may already be running the radial size. Checking the existing tires, wheel width, and overall clearance helps narrow the decision before comparing brands or sidewall styles.
What size rim does a 1959 Peugeot 403 use?
The primary tire sizes associated with the 1959 Peugeot 403 both mount on a 15-inch rim. That applies to the 185R15 radial and the 6.50-15 bias-ply, so wheel diameter remains consistent even though the tire sizing systems and construction types differ.
Wheel diameter is only part of the fitment picture, especially on a collector vehicle that may have seen wheel changes over time. It is still wise to confirm the actual wheel width and overall wheel design before changing tire type, because a tire that shares the same 15-inch diameter may still call for a different wheel-width range or visual presentation.
Does the 1959 Peugeot 403 Sedan & Wagon use the same tire size?
The 1959 Peugeot 403 Sedan & Wagon shares the same primary tire fitment options. Both body styles are associated with the 185R15 radial and the 6.50-15 bias-ply, so there is no separate body-style-specific tire size split within this covered sub-model grouping.
That makes selection more about the car’s present configuration than the body style itself. A sedan and a wagon may both use the same size options, but one example could be restored with a traditional bias-ply look while another is equipped for radial road use. Verifying the wheels and the current tire setup remains the practical next step.
Choosing the Right Tire
What should I consider when choosing a 185R15 or 6.50-15 tire for a 1959 Peugeot 403?
Start with the correct size and construction for the car’s actual setup. The 1959 Peugeot 403 is associated with both a 185R15 radial and a 6.50-15 bias-ply, so the real decision is whether the car is being kept in a more traditional bias-ply configuration or matched to a radial fitment on the same 15-inch wheel diameter.
Once that is settled, compare the details that shape how the car looks and how the tire suits your intended use. Sidewall treatment, tire series, rim-width compatibility, load figures where stated, and the overall visual character of the tire all matter. Those points usually tell you more than simply choosing by size code alone.
What sidewall styles are available for 1959 Peugeot 403 tires?
For the 185R15 radial fitment on a 1959 Peugeot 403, available sidewall styles include Blackwall, Narrow Whitewall, and Redline. Those options give the car a noticeably different visual character even when the tire size stays the same, ranging from understated touring style to a more decorative period-style presentation.
The best sidewall choice depends on how the car is being finished and used. A Blackwall keeps the appearance simple and traditional, a Narrow Whitewall adds a more formal vintage look, and a Redline creates a sportier accent. Matching the sidewall to the car’s trim, stance, and restoration direction usually produces a better result than choosing by color alone.
What brands offer tires for the 1959 Peugeot 403?
Current 185R15 radial choices for the 1959 Peugeot 403 include Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those brands appear across several tire series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport, which gives buyers more than one way to approach the car’s fitment and appearance.
Brand alone should not be the only deciding factor. Compare the available sidewall style, the tire series character, the stated rim-width range where given, and any load information that is relevant to your vehicle use. Once the size and construction are correct, those details usually do the most to separate one option from another.
Restoration & Appearance
Which tire should I choose for a period-style 1959 Peugeot 403?
A period-style 1959 Peugeot 403 usually starts with deciding whether the car should keep a traditional bias-ply presentation or use the radial fitment associated with 185R15. The 6.50-15 bias-ply naturally aligns with a more vintage construction look, while 185R15 radials can still preserve an appropriate older-car appearance depending on the sidewall style selected.
Appearance goals should be matched to how exact the restoration needs to be and how the car will be driven. For a more formal or refined look, sidewall treatment can matter as much as construction. When historical accuracy is especially important, marque-specific references and period photos are worth checking before settling on a final tire style.
How does tire construction affect the appearance of a restored 1959 Peugeot 403?
Tire construction changes more than road feel on a restored 1959 Peugeot 403; it also changes how the car reads visually. A 6.50-15 bias-ply tends to support a more traditional, distinctly vintage presentation, while a 185R15 radial can give the car a slightly more modern visual stance even when the wheel diameter remains 15 inches.
Sidewall style then fine-tunes that result. Blackwall, Narrow Whitewall, and Redline treatments each shift the overall impression of the car, especially on a clean sedan or wagon profile. Owners aiming for a restoration-oriented look usually get the best outcome by considering construction, sidewall treatment, and wheel setup together instead of treating them as separate choices.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1959 Peugeot 403?
Yes, modifications can change tire fitment on a 1959 Peugeot 403 even when the nominal tire size appears correct. Aftermarket wheels, different wheel widths, suspension work, altered ride height, or body repairs can all affect how a 185R15 radial or 6.50-15 bias-ply sits within the fender opening and clears steering and suspension components.
That is why a modified 403 should be checked as an individual car rather than assumed to match a stock setup. Measure wheel diameter and width, inspect the clearance at full steering lock, and look for signs of rubbing or uneven wear. Those checks matter before changing construction type as much as before changing tire size.
What should I inspect before driving a 1959 Peugeot 403 on new tires?
Before driving a 1959 Peugeot 403 on new tires, inspect the wheels for damage or rust, confirm the wheel diameter and width, and make sure the tires seat properly and hold air. It is also smart to check valve stems, lug hardware, and visible suspension or steering wear that could affect how the tires track once the car is moving.
A collector-era car deserves a closer look after installation than a daily driver with a known service history. Watch for side-to-side clearance, verify that the tires do not contact bodywork at lock or over bumps, and set the inflation pressure appropriate for the tire and vehicle use. A short test drive can reveal vibration, pull, or rubbing early.
How should tires on a collector 1959 Peugeot 403 be maintained?
Tires on a collector 1959 Peugeot 403 should be maintained with regular pressure checks, visual inspections, and attention to age-related deterioration. Even a car that is driven lightly can develop sidewall cracking, flat spotting, air loss, or internal aging over time, especially if it spends long periods parked between outings.
Good storage habits help as much as miles-driven maintenance. Keeping the car away from prolonged sun, excess heat, moisture, and ozone sources can preserve the tires, and moving the car periodically helps reduce stress in one contact patch area. Before any longer drive, inspect tread and sidewalls closely rather than assuming low mileage means the tires are ready.
