1968 Peugeot Tire Fitment Guide

1968 Peugeot vehicles use five sizes across two models. The Peugeot 204 uses 135R14. The Peugeot 404 uses 165R15, 590-15, 185R15, and 6.50-15. The 204 size mounts on a 14-inch wheel, while the 404 sizes mount on 15-inch wheels. Where product fitment details are available, 165R15 works with 4.50 to 6.00-inch rims, 590-15 works with 4.00 to 4.50-inch rims, and 185R15 works with roughly 4.5 to 6.5-inch rims depending on the tire.

That split means year and make alone are not enough for a confident tire choice on a 1968 Peugeot. A 204 owner can focus immediately on the 14-inch radial size, while a 404 owner needs to confirm whether the car is staying with a traditional bias-ply approach or moving to one of the radial sizes used on the same basic 15-inch wheel diameter. Checking the wheel itself before ordering is especially important on cars that may have been restored, modified, or fitted with later replacement wheels.

On a 1968 Peugeot, 135R14 is a Euro-metric radial size. The 135 indicates a nominal section width of 135 millimeters, the R identifies radial construction, and the 14 is the wheel diameter in inches. Because no aspect ratio is printed in this style of older metric sizing, it is conventionally treated as an 80-series radial rather than a modern low-profile tire.

That matters because the code tells you this is a narrow, compact-car radial intended for a 14-inch wheel, not a 15-inch 404 fitment and not a modern plus-size substitution. On a 1968 Peugeot 204, the size keeps the car in the proportions expected of a small European sedan of the period. If your wheel or existing tire does not match 14 inches, stop and verify the car’s actual setup before choosing a replacement.

No, 1968 Peugeot models do not all use the same tire size. The 204 uses 135R14 only, while the 404 uses four separate 15-inch sizes: 165R15 and 185R15 in radial construction, plus 590-15 and 6.50-15 in bias-ply construction. Even within the 404 range, the size decision is broader than simply matching a single universal Peugeot specification.

For a buyer, that means the first question is always model identification. Once you know you have a 404, the next step is deciding whether the car is being kept close to an earlier-style bias-ply presentation or whether a radial setup is the better match for how you intend to use it. That distinction affects appearance, road feel, and available sidewall styles, so it is worth sorting out before narrowing the search to a specific tire.

For a 1968 Peugeot 404, the difference between 590-15 and 185R15 starts with construction. The 590-15 is a bias-ply size, while the 185R15 is a radial. The radial side also brings product variation in sidewall style and speed rating, including Michelin XVS options in H-rated form with a 130 mph ceiling and V-rated form with a 149 mph ceiling. The two sizes share a 15-inch rim diameter, but they are not the same kind of tire in behavior or presentation.

A 404 owner focused on traditional period character will usually gravitate toward the bias-ply 590-15, especially for restoration-minded use. A driver who wants a later-style radial feel and more touring-oriented road manners will usually look harder at 185R15. The right answer depends less on the badge on the sidewall than on how the car is used, how authentic the restoration needs to be, and whether the wheel width matches the tire you plan to run.

1968 Peugeot tires span several sidewall treatments depending on size. The 165R15 for the Peugeot 404 is available in blackwall, narrow whitewall, and wide whitewall. The 590-15 bias-ply size comes in blackwall and wide whitewall. The 185R15 radial appears in blackwall, narrow whitewall, and redline. Those choices are concentrated in the 404 range rather than the 204 fitment shown here.

For a French sedan of the late 1960s, blackwall is typically the most natural visual starting point, especially if the goal is a restrained factory-style look. Whitewalls can suit export-market presentation or a more customized appearance, while redlines push the car further from a stock European look. Sidewall style does not change the model fitment itself, but it has a major effect on how authentic or personalized the finished car appears.

1968 Peugeot coverage here comes from Coker Classic, American Classic, Firestone, BFGoodrich, Avon, and Michelin. In 165R15, the available brands are Coker Classic, American Classic, Firestone, and BFGoodrich. In 590-15, the brands are BFGoodrich and Avon. In 185R15, the brands are Coker Classic and Michelin. The mix gives 404 owners several different brand paths across both radial and bias-ply construction.

Brand choice on a 1968 Peugeot is usually about balancing appearance, intended use, and the character of the tire line rather than chasing one universal answer. Michelin naturally appeals to many European-car owners, while BFGoodrich, Firestone, Coker Classic, and American Classic broaden the styling options for a 404 with whitewall or blackwall preferences. Once the correct size is settled, comparing brand-specific sidewall style, load information, and speed rating is the practical next step.

Rim width requirements for 1968 Peugeot tires depend on the size. The 165R15 radial fits rims from 4.50 to 6.00 inches wide. The 590-15 bias-ply fits 4.00 to 4.50-inch rims on the BFGoodrich versions. The 185R15 radial fits roughly 4.5 to 6.5-inch rims depending on the specific tire, with some products using 4.5 to 6 inches and others 5.0 to 6.5 inches. All of those figures apply to the 15-inch Peugeot 404 sizes.

That spread is why wheel width matters just as much as wheel diameter when you are sorting out a 1968 Peugeot 404. A tire may physically share the same 15-inch diameter as another option, yet still ask for a different rim-width window to sit and wear properly. Measure the wheel you actually have on the car, especially if it has seen prior restoration work, before moving from a narrow bias-ply style to a wider radial fitment.

Inner tube requirements on 1968 Peugeot tires depend on the exact size and product. The Michelin 185R15 XVS examples are marked TL, meaning tubeless. The 590-15 and 165R15 products here do not all carry the same explicit marking, so tube status should be confirmed from the individual tire’s sidewall and from the wheel design rather than assumed across the whole size. That is especially important on older European wheels that may have originally been used with tube-type tires.

The practical takeaway is to treat tube fitment as part of the wheel-and-tire system, not just a property of the size code. A tubeless-rated tire still needs a wheel in suitable condition, and an older wheel may still call for tube use depending on its construction and sealing surfaces. Before mounting tires on a 1968 Peugeot, inspect the wheel carefully and match the final setup to the tire’s actual sidewall marking and the wheel’s intended use.

Original 1968 Peugeot wheels cannot be treated as universally interchangeable across the whole make because the 204 uses a 14-inch tire size and the 404 uses 15-inch sizes. Within the 404 family, the sizes do share a 15-inch wheel diameter, so the diameter itself is compatible across those options. Rim width is the limiting factor, since 590-15 and 165R15 do not use the same width range as every 185R15 product.

That means a 404 owner may have flexibility within the 15-inch group, but only after checking the actual wheel width on the car. A narrower original wheel may suit a traditional 590-15 or 165R15 setup better than a wider 185R15 radial, depending on the exact tire chosen. On a 204, the 14-inch size stands alone, so wheel diameter must match that model’s fitment from the start.

A 1968 Peugeot should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber prematurely. Keep the tires clean, maintain inflation, and move the car periodically if it remains on the ground. Bias-ply tires on a Peugeot 404 are generally more prone to temporary flat-spotting during long static periods, while any vintage-style tire can suffer sidewall aging if left in poor storage conditions.

Long storage is easier on the tires when the car is rolled occasionally or supported in a way that reduces continuous load, especially for a collector car that sits for months at a time. If the car will not move for an extended period, cover the tires from light exposure and check pressure before it goes into storage and again before it returns to the road. Good storage habits do more for tire life than low annual mileage alone.

Tire life on a 1968 Peugeot is usually judged more by age than by mileage. Collector-car tires should be inspected regularly from about the five- to seven-year point, and many owners begin serious replacement consideration as tires approach ten years from the DOT date code, even when tread depth still looks usable. That rule applies whether the Peugeot is running a compact 204 radial size or one of the larger 404 sizes.

A lightly driven classic can age out a tire before it wears out, which is why appearance alone is not enough. Sidewall cracking, hardening, vibration, or a tire that no longer holds pressure well can all move replacement higher on the priority list. If the date code is difficult to read or the tire’s history is uncertain, treat age as a safety issue and inspect more conservatively rather than assuming low miles mean long remaining life.

Tires on a 1968 Peugeot should be inspected before every drive and again before any longer trip. Look for cracks in the sidewall, cuts, bulges, uneven tread wear, embedded debris, and pressure loss. On cars using tube-type-compatible vintage tires, it is also wise to pay attention to valve stem condition and any signs of slow leakage that may point to a tube or sealing issue rather than visible tread damage.

Frequent inspection matters because classic Peugeots often spend long periods parked and then return to service for weekend use, rallies, or touring events. A tire that looked fine a month ago can still lose pressure or develop age-related weakness during storage. Building a quick walk-around into the routine before driving helps catch problems early and keeps the tire check aligned with other period-car basics like fluid levels, brakes, and lighting.

A 1968 Peugeot 404 would have been associated in period with both traditional bias-ply sizing and radial sizing, depending on market, equipment, and how the car was delivered or later maintained. The 404 sizes here include 590-15 and 6.50-15 in bias-ply form, along with 165R15 and 185R15 radial options on 15-inch wheels. No original equipment brand should be assumed from that alone, but the construction split reflects the era’s transition from older tire conventions into widespread radial use.

For restoration work, the best approach is to start with the exact model and market history of your 404, then compare that against surviving car evidence, factory literature, and Peugeot marque specialists. A buyer building a show car may want the construction type and sidewall appearance to align closely with the car’s original presentation, while a touring driver may be more flexible. The important point is to verify the car’s story before treating one 404 size as universal.

Correct tire fitment matters on a shown 1968 Peugeot because judges and knowledgeable enthusiasts often notice tire size, construction, and sidewall appearance quickly. On a 204, that means respecting the compact 14-inch radial fitment the model uses here. On a 404, the decision is more nuanced because both bias-ply and radial 15-inch routes exist, and sidewall treatments range from blackwall to whitewall to redline depending on size.

What counts as correct depends on the event and the standard being applied. A concours-style restoration generally benefits from matching the size family and sidewall look that best fits the car’s original delivery era and market, while a casual local show may be far less strict. If authenticity is central to the project, consult Peugeot club resources and period references before committing to a whitewall or radial setup that changes the car’s visual message.

For a 1968 Peugeot 404 in 185R15, Michelin XVS and Coker Classic radial tires differ in sidewall treatment, speed rating range, and some wheel-fit details. Coker Classic appears here as a redline 185R15 with a 1355-pound load rating at 35 psi and a 5.00 to 6.50-inch rim-width range. Michelin XVS appears as narrow whitewall and blackwall versions, both marked TL, with H-rated options carrying a 130 mph ceiling and a V-rated option carrying a 149 mph ceiling; its rim-width range varies by product from about 4.5 to 6.5 inches.

That comparison is useful because the choice is not only about brand identity. A 404 owner chasing a distinct sidewall look may prefer the Coker Classic redline, while someone prioritizing the Michelin touring-style presentation or a specific speed-rating ceiling may lean toward XVS. The wheel width on the car can also steer the decision, since the acceptable rim-width window is not identical across every 185R15 product.

1968 Peugeot tires can be suitable for highway driving when they are in good condition, properly fitted, and used within their construction and speed limits. Among the 404 choices, the 590-15 Avon carries an H rating with a 130 mph ceiling, while Michelin 185R15 options include H-rated versions at 130 mph and a V-rated version at 149 mph. Other sizes here do not all carry explicit speed letters, so the exact tire selected matters. On a car of this era, overall mechanical condition is often just as important as the tire itself.

In practical terms, safe highway use for a 1968 Peugeot depends on more than raw speed capability. Alignment, suspension wear, braking condition, wheel integrity, and inflation accuracy all shape how stable the car feels at modern road speeds. A bias-ply 404 may drive differently from a radial-equipped one, and a compact 204 should still be approached as a 1960s car, not a modern commuter. Match the tire to the car’s purpose and inspect the whole chassis before sustained highway travel.

Inflation pressure on 1968 Peugeot tires should begin with the vehicle manufacturer’s recommendation, then be checked against the tire’s own rated load-and-pressure information. Among the available 404 products, 165R15 tires show load ratings around 1168 to 1170 pounds at 35 to 36 psi, 590-15 BFGoodrich tires show 1050 pounds at 32 psi, and one 185R15 Coker Classic example shows 1355 pounds at 35 psi. Those figures describe the tire’s load capability at those pressures; they are not a blanket instruction to use the same pressure in every Peugeot application.

That distinction matters because inflation is vehicle-specific as well as tire-specific. A reproduction or specialty radial may publish a pressure tied to its rated maximum load, while the car’s original handbook may call for a different operating pressure to achieve the intended ride and contact patch. Use the size that belongs on your Peugeot first, then reconcile the tire maker’s information with the factory recommendation rather than transferring one pressure number from a different size or model.

Before a longer drive in a 1968 Peugeot, inspect each tire for cracking, cuts, bulges, irregular wear, proper inflation, and secure valve stems. Check the spare as carefully as the four road tires, since an old spare is often the least inspected tire on a collector car. If the Peugeot is running a setup that may use tubes, confirm there is no slow leak or valve-stem deterioration. On the 404, also make sure the wheel width and tire choice remain properly matched if the car has been changed from one size family to another.

A longer trip is also the right time to think beyond the tires themselves. Wheel bearing condition, brake adjustment, suspension play, and basic cooling-system and charging-system health all influence whether a vintage Peugeot can use its tires confidently on the road. The goal is not only avoiding a puncture or blowout, but making sure the whole car is ready to support the speeds and distances the trip will demand.
