1961 Simca Tire Fitment Guide

1961 Simca vehicles use six sizes across the range: 185R15 and 6.50-15 for the Arlane; 155R14, 560-14, and 5.75-15 for the Aronde; 155R14 and 560-14 for the Castel, Elysee & Montlry, and Etoile; and 165-15 or 165R15 for the Vedette. The 14-inch group and the 15-inch group do not interchange as a whole, so the correct model and wheel diameter matter first.

Rim-width guidance is available for several of those sizes and should be checked before final selection. 185R15 products span 4.5 to 6.5 inches depending on brand, 155R14 reaches 4.0 to 5.5 inches where specified, 560-14 uses 3.5 to 4.0 inches, and 165R15 uses 4.5 to 6.0 inches. Once the model and wheel size are confirmed, the remaining decision is usually whether to stay with bias-ply character or move to a radial in the corresponding size family.

On a 1961 Simca, 560-14 is a numeric bias-ply size. The 5.60 figure represents the nominal section width in inches, and the 14 indicates a 14-inch wheel diameter. That size belongs to the smaller Simca models such as the Aronde, Castel, Elysee & Montlry, and Etoile rather than the larger Vedette or the Arlane.

Understanding that code helps separate size from construction choice. A 560-14 keeps the early-1960s bias-ply format and is available in blackwall, narrow whitewall, and wide whitewall styles, which can matter for restoration appearance. If your Simca uses a 14-inch wheel but you prefer a radial in the same general fitment family, the comparison point is 155R14 rather than any of the 15-inch sizes.

No. 1961 Simca spans compact and larger passenger cars, and the tire sizes split accordingly. Four models share the 14-inch pair of 155R14 radial and 560-14 bias-ply, while the Arlane uses 185R15 or 6.50-15, the Aronde can also appear with 5.75-15, and the Vedette uses 165-15 or 165R15 on 15-inch wheels.

That means year and make alone are not enough for a confident choice on this page. An owner should identify the exact model first and then confirm the wheel diameter already on the car. That extra step avoids crossing the smaller Aronde-family fitments with the larger-model 15-inch sizes, especially on cars that may have changed wheels during decades of use or restoration.

For a 1961 Simca that uses the shared 14-inch fitment family, the choice between 560-14 and 155R14 is mainly a construction decision. The 560-14 is a bias-ply size associated with period appearance and driving feel, while the 155R14 is a radial size in the same model group for Aronde, Castel, Elysee & Montlry, and Etoile applications.

A restoration aimed at factory-era character usually leans toward the bias-ply route, especially when sidewall styling is part of the presentation. A Simca that will see more regular road use often benefits from staying within the correct model fitment family but using a radial. The key is not to treat them as universal replacements across the whole brand range; they are the right comparison only for the models that actually use the 14-inch setup.

1961 Simca tire choices include more than just blackwall. The 185R15 radial appears in blackwall, redline, and narrow whitewall versions, the 560-14 bias-ply comes in blackwall, narrow whitewall, and wide whitewall, and the 165R15 radial is available in blackwall, narrow whitewall, and wide whitewall forms. The 155R14 radial choices stay in blackwall.

Sidewall style matters most when appearance is part of the goal. Many early-1960s European family cars are most commonly associated with simpler blackwall presentations, while whitewall treatments can suit certain export-market or custom looks. If show authenticity matters, confirm what your specific Simca model and market version wore when new before choosing a whitewall width, because sidewall style can change the whole visual balance of a small car.

1961 Simca fitments are covered by several brands depending on size. 185R15 is available from Coker Classic and Michelin, 155R14 from Michelin and Firestone, 560-14 from BFGoodrich, and 165R15 from Coker Classic, American Classic, Firestone, and BFGoodrich. Brand choice changes with size, so the correct model fitment comes before comparing names on the sidewall.

That brand spread gives owners room to balance appearance and construction within the right size family. Michelin is especially relevant on period French and European applications, while Firestone, BFGoodrich, Coker Classic, and American Classic broaden the sidewall-style options in several sizes. Once your Simca's correct size is settled, brand comparison becomes much more useful because you are looking at products built around the same basic fitment rather than crossing into another model's tire family.

Within the 185R15 fitment used by the 1961 Simca Arlane, Michelin XVS and Coker Classic Radial differ in sidewall presentation, speed marking, and wheel-fit range. Michelin XVS appears in blackwall and narrow whitewall forms, carries H or V speed ratings depending on version, and spans 4.5 to 6.5-inch rim widths depending on the specific tire. Coker Classic Radial appears here as a redline 185R15 with a 5.0 to 6.5-inch rim-width range and a 1355-pound load figure at 35 psi.

That means the decision is not just brand loyalty. A buyer comparing those tires should think about visual style first, then confirm the wheel width on the car, and then decide whether the higher speed-marked Michelin variants align with the way the car will be driven. All of those considerations happen within the same 185R15 size family, so the comparison is meaningful only after the Arlane's correct fitment has already been confirmed.

Rim-width guidance varies by size on 1961 Simca applications. 185R15 products cover 4.5 to 6.5 inches depending on brand and version, 155R14 reaches 4.0 to 5.5 inches where specified, 560-14 uses 3.5 to 4.0 inches, and 165R15 spans 4.5 to 6.0 inches. Those ranges are size-specific and should not be carried over from one Simca fitment family to another.

This matters most on cars that may have had wheel changes during restoration or decades of ownership. A 14-inch Simca wheel and a 15-inch Simca wheel can both look period-correct at a glance, but they lead to completely different tire families. Before choosing between bias-ply and radial, measure or verify the wheel already on the car so the tire's intended rim-width range and diameter match the hardware you actually have.

Tube requirements on 1961 Simca tires depend on the exact size and product. The 185R15 Michelin XVS versions are marked TL for tubeless use, and the 155R14 Michelin X radial is also marked TL. Other sizes and product lines do not carry the same marking here, so tube status can vary by product rather than staying uniform across every tire in the Simca range.

That makes wheel condition and product selection important, especially on original steel wheels. A tubeless-marked tire still needs a wheel and valve setup suitable for tubeless service, while older wheels or certain bias-ply applications may still call for tube use. The safest approach is to confirm the exact sidewall marking on the product you choose and match it to the wheel you plan to run, rather than assuming every tire in the same nominal size uses the same setup.

A stored 1961 Simca should be kept out of direct sunlight, away from ozone-producing equipment such as electric motors and battery chargers, and on a clean, dry surface. Maintaining proper inflation matters even in storage. Bias-ply tires such as 560-14, 6.50-15, 5.75-15, and 165-15 are generally more prone to temporary flat-spotting during long static periods than the radial alternatives used elsewhere in the range.

If the car will sit for extended stretches, move it periodically or support it in a way that reduces constant load on one patch of the tread. That routine helps preserve ride quality and keeps sidewalls from spending months in the same stressed position. A collector Simca that is driven lightly often ages its tires out before it wears them out, so storage habits have a direct effect on how fresh and trustworthy the tires remain.

On a 1961 Simca, tire life is usually limited more by age than by mileage. A good working rule is to evaluate collector-car tires closely once they reach the 5-to-7-year range and to treat around 10 years as the point where replacement deserves serious consideration, even if tread depth still looks respectable. The DOT date code on the tire helps establish that timeline.

This is especially relevant for a hobby car that may only cover a few hundred miles a year. A Simca can appear to have nearly new tires while still carrying rubber that has hardened, cracked, or lost resilience with time. If the car's history is unclear, checking the date code is one of the quickest ways to avoid trusting an old-looking tire simply because it still has ample tread.

Tires on a 1961 Simca should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread separation, cuts, bulges, embedded objects, and signs that the tire is losing pressure over time. On sizes that may involve tube use depending on product and wheel setup, valve stems and any tube-related hardware deserve the same attention as the casing itself.

Frequent inspection matters because collector cars can sit for weeks and then be asked to travel at sustained road speeds. A brief walk-around catches problems early, while a more deliberate inspection before a trip reduces the chance of discovering dry rot or a damaged spare on the shoulder. Pressure checks should be part of the same routine, since underinflation can make an older car feel vague or unsettled long before a failure occurs.

A 1961 Simca Aronde would historically have been associated first with bias-ply construction, since radials were gaining ground in Europe but bias-ply fitments were still common across many early-1960s passenger cars and markets. Within the Aronde family here, the relevant sizes are 560-14 and 5.75-15 for bias-ply use, with 155R14 also appearing as a radial fitment in the broader Aronde-related group.

For a restoration, the right answer depends on which body style, market, and wheel package your Aronde actually carries. Size, wheel diameter, and sidewall presentation all matter, and different export markets could vary. If originality is the goal, use the tire size on the car as a clue but also confirm against period literature or a Simca club before finalizing whether your specific Aronde should wear a 14-inch or 15-inch bias-ply setup.

Correct tire fitment matters on a 1961 Simca because judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall style suit the car's era and model. A bias-ply size on the right wheel diameter usually reads differently than a modern-looking radial, and a wide whitewall can change the impression of a small European car just as much as an obviously incorrect wheel would.

That does not mean every event uses the same standard, but authenticity-focused judging typically rewards a tire that supports the car's original presentation. Owners should think about three things together: the correct model-specific size, the correct wheel diameter, and a sidewall style that makes sense for the car's market and trim. Event rules and marque-club guidance are still the best tie-breakers when two historically plausible options both seem reasonable.

For the 1961 Simca Vedette, 165R15 and 165-15 separate into radial and bias-ply construction while staying on a 15-inch wheel. The 165R15 radial family is available in blackwall, narrow whitewall, and wide whitewall forms from multiple brands, with load figures around 1168 to 1170 pounds at 35 to 36 psi. The 165-15 remains the traditional bias-ply size for the same model line.

That makes the choice one of character and presentation rather than a simple matter of wheel diameter. A Vedette restored for period-correct appearance often favors the bias-ply size family, while a road-driven car may lean toward the radial option while keeping the same 15-inch basic fitment. Because both belong only to the Vedette, owners of smaller 1961 Simca models should not use this comparison as a shortcut for the rest of the lineup.

1961 Simca tires can be suitable for highway use when the correct size, condition, and construction are matched to the car and the driving planned. Among the radial options, 155R14 includes a T-rated version with a 118 mph ceiling, and 185R15 includes H- and V-rated versions with 130 mph and 149 mph ceilings respectively. Those figures are well above normal U.S. highway speeds, but they do not override the car's own age, brakes, suspension condition, or the limitations of bias-ply handling feel.

In practical terms, a sound tire is only one part of a roadworthy Simca. A well-maintained radial-equipped car may feel more settled at modern traffic pace, while a bias-ply car often asks for more attention to tracking and steering response. Before sustained highway use, confirm tire age, inflation, and condition, then judge the whole vehicle honestly as an early-1960s machine rather than assuming the speed marking alone defines safe cruising capability.

Inflation pressure on 1961 Simca tires should start with the vehicle's original guidance, then be checked against the specific tire's own rated figures where those are available. Several reproduction sizes carry clear load-and-pressure pairings: 185R15 reaches 1355 pounds at 35 psi in one version, 155R14 reaches 990 pounds at 44 psi in one version, 560-14 carries 906 pounds at 30 psi, and 165R15 runs around 1168 to 1170 pounds at 35 to 36 psi depending on brand.

Those numbers are not blanket recommendations for every Simca or even every product within the same size. They show the tire's rated capacity at a given pressure, not automatically the ideal running pressure for your specific car. Use the owner's manual or period placard as your baseline, then make sure the tire you choose can support the car at that pressure range. Avoid borrowing a pressure figure from another size simply because it also fits a 1961 Simca.

Before a longer drive in a 1961 Simca, inspect each tire for cracking, bulges, cuts, irregular wear, and signs of air loss. Check cold pressures, confirm the spare is usable, and look closely at valve stems. If your wheel-and-tire combination involves tube use, the condition of the tube-related hardware matters just as much as the tread you can see from outside.

A longer trip is also the right time to think beyond the tires. Wheel fasteners, brakes, steering play, and suspension condition all influence how an older Simca behaves at speed. From the tire standpoint, the goal is to leave with known-good rubber rather than simply acceptable tread depth. That small pre-drive routine is often what separates an enjoyable day on vintage tires from a preventable roadside problem.
