1958 Peugeot 403 Tires

The 1958 Peugeot 403 uses two primary tire sizes: 185R15 in radial construction and 6.50-15 in bias-ply construction. Both sizes are tied to 15-inch wheels, and both apply to the covered Sedan & Wagon fitment.

That means the choice is less about finding one hidden size and more about deciding which construction suits the car and how it is used. A radial 185R15 opens the door to several brand and sidewall options, while 6.50-15 keeps the discussion centered on traditional bias-ply fitment. Wheel condition, actual wheel width, and any older modifications should still be checked before ordering.

The 1958 Peugeot 403 uses a 15-inch rim diameter with both of its primary tire sizes. The radial 185R15 and the bias-ply 6.50-15 are both built around that same 15-inch wheel diameter.

Rim diameter is only part of the fitment picture on a vintage Peugeot. It is still important to confirm the wheel actually on the car, especially if it has been changed at some point, and to compare wheel width against the tire being considered. Staying with the correct 15-inch diameter does not automatically settle clearance, construction, or overall compatibility.

Yes. The covered 1958 Peugeot 403 Sedan & Wagon application shares the same primary tire fitments: 185R15 radial and 6.50-15 bias-ply. The sub-model does not introduce a separate wheel diameter or a different size family.

That simplifies the search, because the main decision shifts from sub-model identification to construction and tire style. An owner choosing a period-style look may focus on the bias-ply path, while someone wanting a radial setup can compare the 185R15 product range by brand and sidewall treatment. It still makes sense to verify the actual wheels on the car before changing tire type.

For the 1958 Peugeot 403, 6.50-15 is a bias-ply tire size. It uses the older numeric sizing format commonly associated with period fitments, and it differs from the 185R15 radial option that also fits this application.

That distinction matters because construction affects both appearance and the kind of tire choices available. Bias-ply is often selected by owners who want a more traditional presentation, while the radial path usually brings a broader mix of brands and sidewall styles. Before moving from one construction to the other, confirm wheel width, overall clearance, and the condition of the suspension and steering components.

A 1958 Peugeot 403 can be fitted with either 6.50-15 bias-ply tires or 185R15 radial tires, so the right direction depends on what matters most for the car. Bias-ply suits a more traditional period-style approach, while 185R15 radial fitment gives access to several modern vintage-style tire choices.

The decision usually comes down to presentation, driving expectations, and the actual wheel setup on the car. A restoration-oriented owner may prefer to preserve the original-era construction style, while a road-use-focused owner may lean toward the radial size already associated with this model. Either way, confirm rim width, tire clearance, and whether any wheel or suspension changes have altered the Peugeot from stock form.

The key checks are wheel diameter, wheel width, and overall clearance at the fenders and steering components. A 1958 Peugeot 403 uses 15-inch wheels in both cases, but moving from 6.50-15 bias-ply to 185R15 radial still changes the construction type and may change how the tire sits on the wheel.

Attention should also go to the car's current condition rather than the catalog fitment alone. Verify that the wheels are suitable for the radial being considered, inspect the suspension and steering for wear, and make sure no past modifications have reduced clearance. A conversion deserves the same caution as any vintage tire change, even when both sizes belong to the same application.

Start with the fact that 185R15 is the radial fitment for the 1958 Peugeot 403 and uses a 15-inch wheel. From there, the important comparisons are brand, tire series, sidewall style, and rim-width compatibility, since the available products vary across those areas.

Some owners will prioritize a restrained blackwall look, while others may want a narrow whitewall or redline to shape the car's presentation. Product details such as rim-width range, load capacity when stated, and even tire weight can also help narrow the field. The best choice is the one that matches the Peugeot's wheels, intended use, and visual direction without drifting away from the proper size.

In 185R15 radial options for the 1958 Peugeot 403, available sidewall styles include blackwall, narrow whitewall, and redline. Those choices give the car noticeably different visual character even when the underlying tire size stays the same.

Sidewall style is often one of the most visible decisions on a restored or preserved 403, especially because the car's modest proportions make tire presentation easy to notice. A blackwall usually creates the most understated look, while a narrow whitewall or redline can add more period flavor. Appearance should still be balanced with the correct size, construction, and wheel compatibility rather than chosen on looks alone.

The 185R15 radial fitment for the 1958 Peugeot 403 is available from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those options span several tire series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport.

Brand choice matters mainly because it shapes the combination of appearance details and product specifications you can compare within the same size family. Some offerings are blackwall only, while others introduce narrow whitewall or redline styling, and rim-width ranges also vary between products. The useful approach is to match the tire to the Peugeot's wheel setup and the kind of presentation you want rather than treating one brand as universally right.

For a period-style 1958 Peugeot 403, the starting point is deciding whether to preserve the traditional 6.50-15 bias-ply fitment or use the 185R15 radial size with a vintage-oriented appearance. Both sizes belong to this application, but they support different restoration priorities.

A buyer focused on construction authenticity may naturally look first at the bias-ply route, while someone balancing vintage character with regular road use may prefer a radial in a restrained sidewall style. Exact originality can vary by market and vehicle history, so owners pursuing a highly exact restoration should compare tire choices against marque references and vehicle-specific documentation before making a final appearance decision.

Tire construction changes more than ride feel on a restored 1958 Peugeot 403; it also changes the car's visual stance and overall presentation. A 6.50-15 bias-ply usually supports a more traditional vintage look, while a 185R15 radial can still look appropriate but often reads as a more road-oriented choice.

Sidewall treatment then adds another layer to the decision, since blackwall, narrow whitewall, and redline versions exist within the radial range. That makes it possible to tune the Peugeot's appearance without leaving the correct size family. Owners concerned with strict historical detail should treat construction and sidewall choice as part of the restoration plan rather than as an afterthought.

Yes. Even though the 1958 Peugeot 403 uses 15-inch tires in both 185R15 radial and 6.50-15 bias-ply form, modifications can still change what works on the car. Wheel width, offset changes, suspension alterations, and body repairs can all influence real-world fitment.

That is especially important on an older vehicle that may have seen decades of repairs or parts substitutions. A Peugeot with aftermarket wheels or altered ride height should be measured rather than assumed correct. Checking steering lock, fender clearance, and tire-to-suspension spacing before installation helps avoid selecting a tire that matches the nominal size but conflicts with the car's actual setup.

Before putting a 1958 Peugeot 403 back on the road with new tires, inspect the wheels, valve stems, and the visible condition of the suspension and steering components. Tire pressure should be set correctly, and the tires should be checked for proper seating and adequate clearance throughout steering travel.

It also helps to think beyond the tires themselves. A collector car that has sat for long periods may have wheel corrosion, worn bushings, or loose front-end parts that affect how new tires behave. A careful first drive, followed by a recheck for air loss or rubbing, is a sensible way to confirm that the Peugeot is ready for normal road use.

Tires on a collector 1958 Peugeot 403 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition as well as tread wear. Even low-mileage vintage cars can develop sidewall cracking, flat spotting, or slow air loss simply from time and storage conditions.

Good maintenance also includes protecting the car from prolonged sunlight, heat, moisture, and ozone-producing equipment during storage. Periodic checks of wheel condition and alignment-related wear are worthwhile, especially if the Peugeot is driven only occasionally. A tire that still has tread can be unsuitable for road use if its age or condition shows clear deterioration.
