Simca Arlane Tires

Simca Arlane uses two listed tire sizes across the 1958 through 1963 model years: 185R15 and 6.50-15. Both are 15-inch fitments, but they are not the same type of tire. The 185R15 is a radial euro-metric size, while 6.50-15 is a traditional numeric bias-ply size. That means the full year range overlaps both sizing systems instead of separating them by early and late production.

The practical question is not just the model year, but which tire standard your particular Simca Arlane is wearing today. Check the tires currently on the car, measure and inspect the wheels, and compare wheel width against the specifications of the tire you are considering. That will tell you whether your car is set up for radial 185R15 tires or for a more traditional 6.50-15 bias-ply fitment.

On a Simca Arlane, 6.50-15 is a numeric bias-ply size. The 6.50 figure is the nominal section width in inches, and the 15 indicates the rim diameter in inches. Unlike modern metric radial sizing, there is no section width in millimeters and no R to indicate radial construction. On this page, 6.50-15 represents the traditional sizing convention used alongside the radial 185R15 option.

That matters because a 6.50-15 tire gives a different period feel and appearance than a modern-style radial. If your Simca Arlane is being restored with traditional bias-ply character in mind, this is the format to look at first. It also calls for a tube, so your wheel condition, tube compatibility, and overall intended use should be checked before finalizing the tire choice.

Simca Arlane uses a 15-inch rim diameter for the listed tire options on this page. The radial 185R15 products are all built for 15-inch wheels, and the 6.50-15 size also identifies a 15-inch rim. There is no wheel diameter change across the 1958 to 1963 production span in the available fitments, even though two different sizing systems appear across the same years.

Wheel diameter is still worth confirming on the actual car, especially on imported or long-owned collector vehicles that may have been changed decades ago. Read the existing tire sidewall, inspect the wheel markings if present, and compare the installed wheel width to the tire specification. Once the 15-inch diameter is confirmed, the remaining choice is whether your Simca Arlane should run a radial or a traditional bias-ply construction.

Simca Arlane fitment depends on which of its two listed tire types you are using. The 6.50-15 bias-ply size requires a tube. The radial 185R15 products shown here are tubeless radial offerings, including tires marked TL in their descriptions. That means tube use is tied to construction and size format rather than to the Simca Arlane name alone.

If your Simca Arlane is staying with numeric bias-ply tires, plan the job around correct tubes and inspect the wheel carefully for rust, pitting, and rim-band issues where applicable. If the car is on radial 185R15 tires, verify that the wheel is appropriate for tubeless radial service and that the wheel width falls within the approved range. Matching the tube decision to the tire construction is part of getting a usable, historically sensible setup.

Simca Arlane is listed with both 6.50-15 bias-ply and 185R15 radial tire sizes across the same 1958 to 1963 years. That means either construction can be appropriate depending on how the car is configured and what kind of driving character you want. Bias-ply preserves a more traditional period feel and appearance, while the radial options follow the later metric-style sizing familiar on many European collector cars.

A restoration focused on authenticity often leans toward the numeric bias-ply size, especially if the car retains a more original character. A driver-oriented Simca Arlane may be better suited to the 185R15 radial options if the wheels are compatible and the goal is more modern road manners. The key is to choose one system deliberately rather than treating the two sizes as interchangeable by default.

Yes, a Simca Arlane on 185R15 radial tires will generally feel different from one on 6.50-15 bias-ply tires because the construction itself changes how the tire responds on the road. Radials typically deliver a more settled, modern driving character, while bias-ply tires usually preserve a more period-correct response and look. The two options listed for Simca Arlane reflect that broader transition in tire technology during the era.

That difference matters most if your Simca Arlane is driven regularly rather than shown or used only occasionally. If originality and historical character are your priorities, the bias-ply route makes sense. If road comfort, steering feel, and a more contemporary touring experience matter more, radial fitment is often the direction owners choose, provided the wheel width and overall setup are appropriate for the radial tire.

Mixing 6.50-15 bias-ply tires with 185R15 radial tires on the same Simca Arlane is not a sound practice. The two constructions flex, respond, and carry load differently, and they are meant to be used as complete sets rather than combined on one car. Since Simca Arlane is listed with both types across the same years, the decision should be made at the vehicle level, not tire by tire.

If your Simca Arlane already has a mixed setup from an earlier owner, the safest path is to standardize the car on one construction and one matched size family. That makes handling more predictable and keeps your spare, replacement planning, and long-term maintenance much simpler. It also helps preserve either a clearly period-correct bias-ply presentation or a clearly radial-equipped driver setup.

A 1958 Simca Arlane is listed with both 185R15 and 6.50-15, and the same overlap continues through 1963. Because both sizes are tied to the same model years, the correct choice comes from the car’s actual wheel and tire setup rather than the year alone. The 185R15 is a radial 15-inch size, while 6.50-15 is a traditional bias-ply 15-inch size with a different sizing convention and different use character.

Start by reading the size on the tires currently mounted, then inspect the wheel width and compare it to the allowed range for the radial options if you are considering 185R15. If the car is a preservation or restoration example, original photos, owner literature, and marque expertise can help determine whether the Simca Arlane should stay with a numeric bias-ply setup or move to the radial alternative already associated with these years.

Simca Arlane radial offerings in 185R15 are available with several sidewall styles, including blackwall, narrow whitewall, and redline. Those styles appear across brands such as Michelin, Coker Classic, and Universal Vintage Tire in the 15-inch radial fitment. That gives Simca Arlane owners a choice between a more understated European look and a more stylized presentation depending on the tire selected.

For a restrained, period-sensitive Simca Arlane restoration, blackwall or a subtle narrow whitewall will usually align more naturally with the car’s character than a more overt custom look. Redline can suit an owner who wants a distinctive visual treatment, but it changes the overall presentation. Sidewall style should be chosen with the same care as size and construction, since appearance is a major part of how a collector car reads at a glance.

Simca Arlane tires in the listed 185R15 size are available from Coker Classic, Michelin, Avon, and Universal Vintage Tire. Those products include radial series such as Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport. The page shows multiple brands within the same 15-inch radial fitment, giving owners several ways to approach appearance and driving character while staying within the correct general size family.

Brand choice matters after the basic fitment decision has already been made. Once you know your Simca Arlane should use 185R15 rather than 6.50-15, you can compare sidewall style, rim-width compatibility, and the overall look you want from the car. A touring-minded owner may prefer one approach, while a restorer focused on visual authenticity may prefer another, even within the same size.

Simca Arlane radial products are offered in several series, including Coker Classic Radial, Michelin XVS, Turbosteel CR3B, and Universal Sport. All of them fall within the radial side of the Simca Arlane fitment picture, but they differ in brand identity, sidewall presentation, and in some cases the exact marking style shown on the tire. Michelin XVS appears in blackwall and narrow whitewall forms, while Coker Classic and Universal Sport include redline offerings.

Choosing among series is usually the final step after deciding that your Simca Arlane will run 185R15 radial tires. At that point, compare the visual effect each series creates, along with the wheel-width range where listed. If your goal is a cleaner European appearance, one series may look more at home; if the car is being personalized, another may suit better without changing the fundamental 15-inch radial fitment.

A stored Simca Arlane should be kept in a cool, dry, dark space with the tires protected from sunlight, ozone sources, and large swings in temperature. Clean concrete, painted floors, or tire pads are preferable to damp earth or oily surfaces. Inflate the tires properly before storage and roll the car occasionally if practical so one section of the tread is not carrying the same load for months at a time.

Collector cars often age their tires by inactivity rather than mileage, and Simca Arlane is no exception. If the car will sit for an extended period, inspect for sidewall cracking, flat spotting, and bead-area deterioration when it comes back into use. A little storage discipline preserves both appearance and road manners, especially on a smaller vintage car where tire condition can strongly influence how settled the car feels.

Tires on a Simca Arlane should be inspected before each meaningful drive and more thoroughly at regular intervals during the season. Check inflation, sidewall condition, tread surface, valve stems, and any signs of age-related cracking or separation. On a low-use collector car, visual condition and age matter far more than tread wear alone, because the tires may still look full-tread while the rubber has already hardened.

That routine is especially important if your Simca Arlane alternates between short local use and long storage periods. A quick walkaround catches problems early, while a more careful inspection can reveal issues hidden on the inner sidewall or around the bead. Keep the spare under the same inspection schedule, since an old but unused spare may be the least trustworthy tire on the whole car.

Tires on a Simca Arlane should be replaced when age, cracking, hardening, bulges, impact damage, or structural deterioration appear, even if the tread still looks deep. Collector-car tires often time out before they wear out. That is true for both radial and bias-ply construction, and it is especially important on a car that spends long periods parked, where rubber can age quietly without accumulating many miles.

Use tread depth as only one part of the decision. If the Simca Arlane shows vibration, wandering, repeated air loss, or visible sidewall changes, the tires deserve immediate attention. For a car that is driven infrequently, age and condition should guide replacement planning more than mileage, because an older tire can become the weak link in an otherwise carefully maintained collector vehicle.

Simca Arlane is associated here with both 6.50-15 and 185R15 across the 1958 to 1963 years, which places the model in an overlap between traditional numeric sizing and later radial-style fitment. The available products shown on this page are radial offerings in 185R15, while the model-year listing also includes the older 6.50-15 format. That means original-equipment direction should be narrowed by the individual car’s build period, market history, and surviving reference material.

For a restoration, the safest path is to compare the car against factory literature, period photos, and marque knowledge before deciding whether the Simca Arlane should wear a numeric bias-ply tire or a radial-sized equivalent. Restorers often find that the tire choice influences the whole look of the car, from stance to sidewall character. Getting that decision right helps the finished car read as coherent and historically believable.

Correct tire fitment can absolutely affect how a Simca Arlane is judged, presented, and valued, especially in a restoration context. Size, construction type, and sidewall style all influence whether the car looks consistent with its era and intended specification. A Simca Arlane fitted with an obviously mismatched tire type may still be drivable, but it can lose points in formal judging and credibility with knowledgeable enthusiasts.

That does not mean every Simca Arlane must be restored the same way. A touring-oriented owner may choose radial practicality, while a concours-focused owner may prefer a more traditional bias-ply presentation if that aligns with the car’s history. The important step is making a deliberate choice and being able to justify it through period references, marque-club guidance, and the overall restoration objective.

Simca Arlane radial products are available in blackwall, narrow whitewall, and redline sidewall styles. Of those, blackwall and narrow whitewall are generally the more restrained, period-sensitive visual choices for a late-1950s to early-1960s European family car, while redline creates a more customized look. The right answer depends on whether the goal is a historically sympathetic restoration or a personalized presentation using a correct general tire size.

A restorer should evaluate sidewall style the same way they evaluate paint finish, wheel trim, and interior materials: as part of the car’s full visual story. On a Simca Arlane, blackwall usually gives the cleanest factory-like appearance, while narrow whitewall can suit certain period tastes. Redline works best when the owner accepts that the car’s stance and style are being interpreted rather than kept strictly conservative.

A Simca Arlane can be driven on public roads when the tires are the correct size, construction, and condition for the car, and when the rest of the vehicle is mechanically sound. The listed fitments include both radial and bias-ply approaches, and either demands sound wheels, proper inflation, and age-appropriate condition. Tire safety on a collector car is never just about tread; age, storage history, and structural integrity matter just as much.

Before regular road use, treat the tires as one part of a larger readiness check that includes brakes, steering, suspension, and wheel hardware. A Simca Arlane that feels light and simple can still become unsettled quickly if the tires are aged, underinflated, or mismatched. Public-road use is realistic for a well-prepared example, but the car should be approached with the caution due any vintage automobile.

Before driving a Simca Arlane, inspect tire pressure, visible sidewall condition, tread surface, valve stems, and overall wheel security. Confirm that all four tires match in size family and construction, especially because Simca Arlane is associated with both 185R15 radial and 6.50-15 bias-ply fitments. If the car uses the numeric bias-ply size, include the tube-equipped setup in your inspection routine and look for signs of air loss or rim-related issues.

A short pre-drive check prevents many of the problems that spoil old-car outings. Pay attention to how the Simca Arlane felt on the previous drive; any new vibration, pull, or wandering deserves investigation before heading farther from home. Vintage cars often give subtle warnings before a tire issue becomes serious, so taking those hints seriously is part of responsible road use.

Appropriate speed for a Simca Arlane depends on the tire type fitted, the tire’s condition, and the overall mechanical condition of the car. A Simca Arlane on traditional 6.50-15 bias-ply tires should generally be driven with more restraint than one on modern-production 185R15 radial tires, even when both are correctly fitted. Vintage tire behavior, braking capability, and chassis feel all need to be respected rather than judged by modern-car standards.

The sensible approach is to let the car tell you what feels stable and composed, while staying well within the capabilities of an early-1960s compact automobile. If the Simca Arlane is newly returned to the road, begin with shorter local drives and moderate speeds until the full setup proves itself. Smooth inputs, conservative cruising, and regular inspections will do more for safe enjoyment than chasing modern traffic pace.
