1958 Peugeot came from a period when the French marque was building practical, technically interesting sedans with a strong reputation for ride quality, economy, and long-distance road manners. In the U.S. collector world, the 203 and 403 appeal to owners who value distinctive postwar European engineering and authentic period character. Tire choice across 1958 Peugeot models varies by model rather than staying uniform: the 203 uses three radial sizes, while the 403 splits between a radial and a bias-ply option. That means the first thing to confirm is which model you have, and then whether you want to stay close to an era-correct construction approach or prioritize a more modern radial driving feel.
Which Tire Size Is Right for Your 1958 Peugeot
Five tire sizes appear across 1958 Peugeot vehicles, and they vary by model rather than being shared across the full range. The main decision starts with identifying whether you have a 203 or a 403, then confirming whether your car uses a 15-inch or 400mm wheel before narrowing the choice by construction and driving intent. Understanding that distinction first saves time and helps you match the tire to the car.
155-400 is a metric radial size with a 155-millimeter nominal section width and a 400mm rim diameter, making it specific to 1958 Peugeot 203 models rather than universal across the year and make. No current product range is listed here, so the key point is that it is a metric radial built around the original French wheel standard rather than a 15-inch conversion size. It suits a 203 owner who needs to stay with the 400mm wheel format and should be matched carefully to the actual wheel on the car.
Year(s): 1958|Fit(s): 203|Construction: Radial|Rim: 15 in
155R15 is a metric radial with a 155-millimeter nominal section width and a 15-inch rim diameter; when no aspect ratio is shown in this format, it conventionally represents an 80-series type radial. Firestone and Michelin offer it in blackwall form, and tube status and speed rating vary by product, including T-rated tires to 118 mph, H-rated tires to 130 mph, and both TT and TL versions. This size is specific to the 1958 Peugeot 203 and is the practical choice for owners using 15-inch wheels who want a radial in a compact, period-appropriate metric size.
185-400 is a metric radial size with a 185-millimeter nominal section width and a 400mm rim diameter, and it is used only on the 1958 Peugeot 203. No listed products are attached to this size here, but the code still points to a wider radial built for the original 400mm wheel standard rather than a 15-inch wheel. It is the size to research when a 203 still retains its metric wheels and calls for a broader radial fitment within that original format.
Year(s): 1958|Fit(s): 403|Construction: Radial|Rim: 15 in
185R15 is a metric radial with a 185-millimeter nominal section width and a 15-inch rim diameter; in this style of sizing, the unstated profile conventionally falls into the 80-series range. Coker Classic and Michelin offer this size in redline, narrow whitewall, and blackwall versions, and speed ratings vary by product, including H to 130 mph and V to 149 mph, with the listed products all using TL construction. This size is specific to the 1958 Peugeot 403 and gives owners a radial option with several visual styles depending on whether the goal is understated touring appearance or a more period-styled sidewall look.
Year(s): 1958|Fit(s): 403|Construction: Bias Ply|Rim: 15 in
6.50-15 is a numeric bias-ply size in which 6.50 refers to nominal section width and 15 is the rim diameter in inches. No listed products are attached here, so the main distinction is construction: this is the bias-ply fitment associated with the 1958 Peugeot 403 rather than a radial alternative. It is the size to pursue when the goal is to keep a 403 closer to mid-century tire construction and steering feel.
Two Peugeot model lines are covered for 1958. They do not share the same tire sizes, so identifying whether you have a 203 or a 403 matters before you choose a tire. Select your model below to narrow the fitment history and available products.
1958 Peugeot 203
The 1958 Peugeot 203 was the marque’s compact postwar family car, known for its rounded styling and durable mechanical character. Its tire choices span both 400mm and 15-inch radial fitments, so wheel type is just as important as model identification when sorting out the correct replacement size.
The 1958 Peugeot 403 moved Peugeot further upmarket with a roomier body and a more formal, modern look that later became familiar well beyond Europe. Its listed tires mount on 15-inch wheels, but the model spans both radial and bias-ply sizing, so the decision often comes down to the kind of driving character and presentation you want from the car.
Eight products are available across two tire sizes for 1958 Peugeot vehicles. The 155R15 range includes four radial blackwall choices from Firestone and Michelin, while 185R15 includes four radial options from Coker Classic and Michelin in redline, narrow whitewall, and blackwall styles. Confirm your size first, since speed ratings and tube status can vary within 155R15.
These FAQs sort out the real decisions for 1958 Peugeot owners: 203 versus 403 fitment, 400mm versus 15-inch wheels, radial versus bias-ply choices on the 403, and the sidewall and setup details that matter on a collector car.
Size Basics & Fitment
What tire sizes fit 1958 Peugeot vehicles?
1958 Peugeot vehicles use five sizes across two model lines. The Peugeot 203 uses 155-400, 155R15, and 185-400, while the Peugeot 403 uses 185R15 and 6.50-15. The 15-inch sizes are 155R15, 185R15, and 6.50-15, while 155-400 and 185-400 are metric-wheel sizes built for 400mm rims rather than 15-inch rims.
The practical point is that year and make alone are not enough on a 1958 Peugeot. Start by identifying the model, then confirm whether the car still carries 400mm wheels or has 15-inch wheels. If you are looking at a 15-inch radial, the listed rim-width ranges are 4.00 to 5.50 inches for 155R15 and roughly 4.5 to 6.5 inches for 185R15 depending on the product.
What does 155R15 mean on a 1958 Peugeot tire?
On a 1958 Peugeot, 155R15 is a metric radial size. The 155 refers to a nominal section width of 155 millimeters, the R identifies radial construction, and the 15 is the wheel diameter in inches. In this style of older metric sizing, the aspect ratio is not written into the size, but it is conventionally treated as an 80-series type radial.
That matters because 155R15 belongs to the 1958 Peugeot 203 and fits a 15-inch wheel, not a 400mm wheel. Within this size, products appear in blackwall form from Firestone and Michelin, and the details vary by tire, including T- and H-speed-rated versions and both tube-type and tubeless versions. Checking the full sidewall marking is important before choosing one.
Do all 1958 Peugeot models use the same tire size?
No, 1958 Peugeot models do not share one universal tire size. The 203 uses three radial sizes—155-400, 155R15, and 185-400—while the 403 uses either 185R15 radial or 6.50-15 bias-ply. That means the fitment changes by model, and in the case of the 203 it can also change by wheel standard.
A buyer who skips the model step can easily end up comparing the wrong tires. The 203 often sends you first toward a 400mm-versus-15-inch wheel decision, while the 403 sends you toward a radial-versus-bias-ply decision on a 15-inch wheel. If the car has been restored or converted over the years, verify the wheel itself before settling on a size.
Buying the Right Tire
Should I choose the 185R15 or the 6.50-15 for my 1958 Peugeot?
On a 1958 Peugeot 403, the real difference between 185R15 and 6.50-15 is construction. The 185R15 is a radial 15-inch size, while 6.50-15 is a numeric bias-ply 15-inch size. That does not make them interchangeable by assumption, but it does frame the choice around the kind of driving character and period presentation you want from the car.
Owners leaning toward regular road use often prefer to explore the radial route, especially since 185R15 is offered in several sidewall treatments. Owners focused on a more mid-century look and feel often start with the bias-ply size instead. Before choosing either one, confirm that your 403 is actually set up for that size and that the wheel dimensions and clearances support it.
What sidewall styles are available for 1958 Peugeot tires?
Sidewall styling depends on the size chosen for a 1958 Peugeot. The listed 155R15 options for the Peugeot 203 are blackwall only. The listed 185R15 options for the Peugeot 403 expand the look considerably, with blackwall, narrow whitewall, and redline versions available.
For a restrained European presentation, blackwall is the easiest match to the understated character most buyers expect from a late-1950s Peugeot. Narrow whitewall or redline treatments create a more stylized appearance and may appeal more to an owner building around a personal period look than a strict factory-style restoration. If event judging matters, confirm the accepted sidewall treatment with a Peugeot club or marque specialist.
What brands make tires for 1958 Peugeot vehicles?
Three brands appear in the current 1958 Peugeot product range. The 155R15 size is offered by Firestone and Michelin, while 185R15 is offered by Coker Classic and Michelin. Both available sizes in the listings are radial constructions, with Michelin covering several versions and speed ratings within each size.
Brand choice on a 1958 Peugeot usually comes down to the exact size you need, the sidewall appearance you want, and whether a particular speed rating or tube configuration matters for your setup. Michelin has especially strong relevance on period European applications, while the broader point for any owner is to match the tire’s full specification to the car rather than choosing by brand name alone.
Fitting & Setup
What rim width do 1958 Peugeot tires require?
For 1958 Peugeot tires with listed rim-width guidance, 155R15 fits rims from 4.00 to 5.50 inches wide. The 185R15 range spans roughly 4.5 to 6.5 inches depending on the specific product, with some versions listed for 4.5 to 6 inches and others for 5.00 to 6.50 inches. All of those products mount on 15-inch rims.
That means rim width is a product-by-product check, not just a size check. A 15-inch wheel may have the correct diameter but still fall outside a tire’s approved width range. Measure the actual wheel, especially on a restored or long-owned car, and compare it to the individual tire you are considering rather than assuming every 185R15 has identical wheel requirements.
Do 1958 Peugeot tires require inner tubes?
Inner-tube requirements vary within the listed 1958 Peugeot radial range. In 155R15, some products are clearly tubeless while at least one is tube-type, so that size cannot be treated as one or the other across the board. In 185R15, the listed products are tubeless.
The takeaway is simple: check the exact sidewall marking on the specific tire you are considering. A 1958 Peugeot owner should also remember that wheel condition matters just as much as tire construction, especially on older wheels that may have seen multiple restorations or decades of storage. If you are retaining original wheels, inspect them carefully before deciding whether a tube-type or tubeless setup is appropriate.
Maintenance, Storage & Longevity
How should I store a 1958 Peugeot when the tires are fitted?
A stored 1958 Peugeot should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Tires last better when they are kept clean, off damp ground, and protected from long periods of one-position loading. Collector cars that sit for extended stretches also benefit from periodic movement or carefully using stands to reduce static stress.
That advice matters whether your car wears radial or bias-ply tires, but the 403’s bias-ply option deserves extra attention because older-style constructions tend to show flat-spotting more readily during long stationary storage. If the car will be parked for months at a time, keep inflation checked and avoid leaving one corner under low pressure, which can accelerate sidewall fatigue and carcass distortion.
How long do tires on a 1958 Peugeot typically last?
Tire life on a 1958 Peugeot should be judged by age and condition more than by miles driven. Collector-car tires often age out before they wear out, so a good rule is to evaluate them closely once they reach about five to seven years old and to treat around ten years as a serious replacement point regardless of tread depth. The DOT date code on the tire helps establish age.
A lightly used Peugeot can look fine at a glance while the rubber has already hardened or cracked with age. That is especially relevant on a car used for seasonal drives, local shows, or occasional tours. Sidewall checking, pressure retention, and ride changes are often more meaningful signs than tread wear, so age should stay at the center of your maintenance plan.
How often should tires on a 1958 Peugeot be inspected?
Tires on a 1958 Peugeot should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, and signs that the tire has been run underinflated. If your setup uses a tube-type tire, the valve stem and the wheel’s condition deserve the same attention as the tread and sidewall.
Frequent inspection matters on an older Peugeot because the car may spend more time parked than driven, and storage-related aging can be easy to miss. A quick pre-drive check takes only a few minutes and can catch a weak spare, a slow leak, or a deteriorating valve stem before it becomes a roadside problem. Longer tours justify a more thorough walkaround and pressure check.
Restoration & Authenticity
What tires were originally fitted to the 1958 Peugeot 203?
A 1958 Peugeot 203 would have been a radial-era European car, and the listed 203 sizes are all radial: 155-400, 155R15, and 185-400. That fits Peugeot’s place in a market where metric wheel standards and early radial adoption were part of the ownership experience. The exact original fitment can still vary with market, wheel type, and prior restoration choices.
For a serious restoration, the first step is to confirm whether your 203 still carries its original 400mm wheels or has been moved to 15-inch wheels over time. Once that is settled, you can narrow the correct size family much more confidently. If the car is being prepared for show judging, a Peugeot club or marque specialist is the right source for market-specific confirmation beyond the broad radial construction pattern.
Does correct tire fitment matter for showing a 1958 Peugeot?
Correct tire fitment can matter quite a bit when showing a 1958 Peugeot, especially in classes that reward factory-style presentation. Judges and knowledgeable enthusiasts often notice whether the car carries the right size family, the expected construction type for the model, and an appropriate sidewall appearance for the car’s market and period. A visibly modern-looking substitute can change the car’s overall impression even if it physically fits.
That does not mean every event applies the same standard. A touring-oriented local show may be flexible, while a marque-driven or concours-style event can be much more particular. If authenticity is your priority, use the model-specific size as your starting point, then confirm whether the sidewall should be plain blackwall or another period treatment before finalizing the tire choice.
What is the difference between Michelin XVS and Coker Classic Radial for the 1958 Peugeot?
For a 1958 Peugeot 403 in 185R15, Michelin XVS and Coker Classic Radial differ in sidewall offerings, speed rating, rim-width guidance, and listed load information. Michelin XVS appears in blackwall and narrow whitewall forms, with H-rated versions to 130 mph and a V-rated version to 149 mph. The Coker Classic Radial appears here as a redline with a listed maximum load of 1355 pounds at 35 psi and a 5.00 to 6.50 inch rim-width range.
That makes the decision less about one being universally better and more about which specification matches your 403. A buyer seeking a specific sidewall look may focus first on redline versus blackwall or narrow whitewall, while a buyer concerned with wheel width or speed rating should compare those figures carefully. Since all of these are 15-inch radials, the finer details are what separate them.
Safety & Road Use
Are 1958 Peugeot tires safe for highway driving?
1958 Peugeot tires can be suitable for highway driving when the size, construction, condition, and speed rating all match the intended use. The listed 155R15 products include T-rated tires to 118 mph and H-rated tires to 130 mph, while the listed 185R15 products include H-rated versions to 130 mph and a V-rated version to 149 mph. Those figures are well above normal highway speeds in proper condition.
Real-world safety in a 1958 Peugeot still depends on more than the tire’s speed letter. Brakes, suspension condition, steering wear, wheel integrity, and alignment can matter just as much on a late-1950s car. Treat the tire as one part of the system, and do not judge highway readiness by tread depth alone if the rubber is old or the chassis has not been recently checked.
What inflation pressure should I use for 1958 Peugeot tires?
Inflation pressure on a 1958 Peugeot should follow the vehicle recommendation for the specific model and the tire maker’s limits for the exact tire you are using. Among the listed products, 155R15 includes a tire rated at 1045 pounds at 44 psi, and 185R15 includes a tire rated at 1355 pounds at 35 psi. Those figures are tire ratings, not blanket inflation recommendations for every Peugeot application.
Use the owner’s manual or period service information as the starting point for the car, then confirm that the selected tire’s load and pressure ratings support that use. Do not transfer a pressure number from 155R15 to 185R15, or from a radial to a bias-ply 6.50-15, because the construction and intended operating range differ. Matching pressure to the exact tire is essential.
What should I check before taking a 1958 Peugeot on a longer drive?
Before a longer drive in a 1958 Peugeot, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation. Check the spare as carefully as the four road tires, and look closely at valve stems, especially if your setup uses a tube-type tire. Wheel fastener security, wheel condition, and any sign of air loss deserve attention before the trip begins.
A longer outing also calls for a broader mechanical check that fits the age of the car. Cooling system health, brake feel, steering play, and charging-system confidence all matter on a 1958 Peugeot just as much as tire condition. When the car has been sitting, a short local test drive before the main trip is often the best way to uncover vibration, pull, or pressure-retention issues.
