1963 Simca Tire Fitment Guide

1963 Simca vehicles use eight sizes across five model lines. The Simca 1000 uses 145R13, 5.50-13, 155R12, or 5.60-12 depending on wheel setup. The Arlane uses 185R15 or 6.50-15. The Castel, Elysee, and Etoile use 155R14 or 560-14. Rim width guidance appears within some product ranges: 145R13 works on 4.00 to 5.00-inch rims, 185R15 on 4.5 to 6.5-inch rims depending on product, 155R14 on 4.00 to 5.50-inch rims, and 560-14 on 3.50 to 4.00-inch rims.

That spread means year and make alone are not enough for a correct tire decision on 1963 Simca. Start by identifying the exact model, then confirm the wheel diameter actually on the car, especially with a Simca 1000 where both 12-inch and 13-inch fitments appear. Once the model and rim diameter are settled, the next step is choosing between the original-style bias-ply path and the radial path where both exist.

On a 1963 Simca, 560-14 is a numeric bias-ply size. The 5.60 figure is the nominal section width in inches, and the 14 means the tire mounts on a 14-inch wheel. That size is used on the Simca Castel, Elysee, and Etoile. Available versions come from BFGoodrich and include blackwall, narrow whitewall, and wide whitewall styles.

Numeric sizes like 560-14 are common on mid-century cars and feel more natural to restorers than modern metric markings. For a 1963 Simca sedan in this family, that size points toward an original-style visual stance and bias-ply construction, which matters if the car is being prepared for vintage presentation. It is still important to confirm wheel width before final selection, since 560-14 products are intended for relatively narrow rims.

No, 1963 Simca models do not share one universal tire size. The Simca 1000 has four possible sizes across 12-inch and 13-inch wheel setups, the Arlane uses 15-inch sizes, and the Castel, Elysee, and Etoile share two 14-inch sizes. Even where two sizes belong to the same model, they may represent different constructions rather than random interchangeability.

That matters because a buyer can be correct on year and make yet still choose the wrong tire family if the model is not confirmed first. The Simca 1000 is the most important example, since it spans two rim diameters. The safest workflow is to identify the model, read the size already on the tire or wheel if possible, and then compare that against the appropriate size family for that specific 1963 Simca.

For a 1963 Simca Castel, Elysee, or Etoile, the choice between 155R14 and 560-14 is mainly a construction decision. The 155R14 is a radial in a metric-style format, while the 560-14 is a bias-ply in a traditional numeric format. The radial choices are blackwall tires from Michelin and Firestone, while the 560-14 family from BFGoodrich adds blackwall, narrow whitewall, and wide whitewall variations.

Owners who want an appearance closer to period practice often lean toward the 560-14, especially if sidewall styling is part of the restoration plan. Owners who expect more regular road use often prefer to stay within the 155R14 radial family. The important thing is to keep the choice tied to the correct 14-inch wheel and to the kind of driving and presentation the car is meant to have.

Sidewall style varies a good deal across 1963 Simca tire sizes. The 145R13 and 155R14 radial choices are blackwall only. The 185R15 radial family for the Arlane adds blackwall, narrow whitewall, and redline options. The 560-14 bias-ply family for the Castel, Elysee, and Etoile is available as blackwall, narrow whitewall, or wide whitewall.

That variety affects both appearance and authenticity. Blackwall is the safest visual baseline on small European cars of this era, while whitewall and redline treatments can shift the car toward a more stylized presentation depending on market taste and restoration goals. If show accuracy matters, check how your specific 1963 Simca was delivered in its market and trim, then match the sidewall style to that history rather than choosing by looks alone.

1963 Simca fitments are covered by Michelin, Firestone, Coker Classic, and BFGoodrich across the currently available sizes. Michelin and Firestone cover 145R13, Michelin and Firestone also cover 155R14, Coker Classic and Michelin cover 185R15, and BFGoodrich covers 560-14. Brand choice depends on the size first, because not every brand appears in every Simca fitment family.

That brand spread gives 1963 Simca owners a useful mix of European-style radial offerings and classic American reproduction bias-ply options. Michelin naturally aligns well with period French and European tire culture, while Firestone, BFGoodrich, and Coker Classic broaden the styling and restoration choices. Once the size is confirmed, comparing sidewall style, rim-width compatibility, and any speed-rating differences is more productive than trying to choose a brand in the abstract.

Rim width recommendations for 1963 Simca tires depend on the exact size. 145R13 fits 4.00 to 5.00-inch rims. 185R15 spans 4.5 to 6.5-inch rims depending on the product, with some versions starting at 4.5 inches and others at 5.00. 155R14 fits 4.00 to 5.50-inch rims. The 560-14 bias-ply size fits 3.50 to 4.00-inch rims.

Those ranges are important because two tires with the same rim diameter are not automatically intended for the same wheel width. A 14-inch wheel for a 560-14, for example, is much narrower than many 14-inch radial applications. Before selecting a tire for any 1963 Simca, measure the wheel or confirm its width from the wheel stamping or service literature so the tire and rim work together as intended.

Tube requirements for 1963 Simca vary by size and product family. The 145R13 Michelin option is marked TL, the 185R15 Michelin choices are marked TL, and the 155R14 Michelin option is also marked TL, all indicating tubeless construction. Other sizes here do not carry the same explicit marking in every product description, so tube use should be matched to the exact tire and wheel combination rather than assumed across the whole year and make.

The practical check is not just the tire, but also the wheel. A tubeless-marked tire still needs a wheel in suitable condition, and many older collector-car wheels raise separate sealing concerns around the bead area or rivets. If your 1963 Simca still has original wheels, confirm the sidewall marking on the specific tire you choose and inspect the wheel condition before deciding whether a tube is appropriate.

A stored 1963 Simca should be kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that age rubber. Clean, dry floors and stable temperatures help, and the car should be moved periodically or supported in a way that reduces long static loading. Bias-ply tires such as 5.50-13, 5.60-12, 6.50-15, and 560-14 are generally more prone to flat-spotting during long storage than the radial alternatives used on other 1963 Simca fitments.

That means storage strategy should reflect how your Simca is equipped. A car parked for months on bias-ply tires benefits from regular rolling or temporary support to avoid sitting on one footprint. Regardless of construction, keep inflation checked during storage and inspect sidewalls before the first drive of the season. Collector cars age their tires by time and environment as much as by mileage.

On a 1963 Simca, tire age matters more than accumulated miles in most collector use. A sensible rule is to begin close inspection and evaluation around the five- to seven-year mark and to treat around ten years as a serious replacement point even if the tread still looks good. The DOT date code on the tire is the starting point for establishing age, although some period-style products may display markings differently than a modern daily-driver tire.

That approach matters because many vintage cars see short trips, garage storage, and long idle periods, all of which can hide age-related deterioration. Sidewall checking, hardening of the rubber, loss of pressure retention, and changes in ride behavior can arrive before the tread is worn out. A low-mile 1963 Simca should be judged by condition and age first, with mileage as a distant secondary factor.

Tires on a 1963 Simca should be inspected before every drive, and more carefully before any longer outing or touring event. Look for sidewall cracking, bulges, cuts, embedded debris, uneven wear, and any sign that the tire has been run underinflated. If the car uses a tube-type setup, the valve stems and pressure retention deserve extra attention because leaks can appear without obvious tread or sidewall damage.

A brief pre-drive walkaround catches many issues before they turn into roadside problems. Long-stored collector cars can lose pressure gradually, and an old spare tire may be in worse condition than the four on the ground. Make tire inspection part of the same routine as checking fluids, brake feel, and lighting, especially before taking a 1963 Simca beyond local roads.

For a 1963 Simca 1000, original-era fitment would have centered on bias-ply construction, since radial adoption was growing in Europe but bias-ply remained part of the period picture on many small cars and in many markets. The size family for the model includes 5.50-13 and 5.60-12 as bias-ply choices, alongside 145R13 and 155R12 radial alternatives. The exact original size depended on the wheel setup and market specification rather than one universal Simca 1000 answer.

That means a restorer should first confirm whether the car carries 12-inch or 13-inch wheels, then decide whether the goal is factory-era appearance or regular driving manners. If originality is the priority, a bias-ply route usually aligns more closely with the period character of a 1963 Simca 1000. For trim- and market-specific confirmation, a Simca club or marque specialist is still the best source before finalizing a concours restoration.

Correct tire fitment matters on a shown 1963 Simca because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall treatment immediately. A radial can look out of place on a car judged for factory-style originality if the event expects a bias-ply presentation, and an aggressive decorative sidewall can raise the same issue if it does not suit the car's original market character. The right wheel diameter is basic, but the visual and historical details matter too.

That does not mean every 1963 Simca must wear the same style. A touring car built to be driven regularly may reasonably prioritize radial construction, while a concours car may need a stricter period-correct approach. The best path is to match the tire to the standard of the event you plan to enter and to verify any club-specific expectations before spending time and money on a full cosmetic restoration.

For the 1963 Simca Arlane's 185R15 size, Michelin XVS and Coker Classic serve different presentation niches even though both are radial tires. Michelin XVS appears in blackwall and narrow whitewall forms, with H-rated versions to 130 mph and a V-rated version to 149 mph, all on 15-inch rims. Coker Classic appears here as a redline radial with a 5.00 to 6.50-inch rim-width range and a maximum load rating of 1355 pounds at 35 psi.

The decision comes down to what kind of Arlane you are building. Michelin XVS leans toward a European touring look and gives the clearest speed-rating differentiation within the size, while the Coker Classic redline emphasizes a more stylized period appearance. Either way, the tire should be matched to the wheel width on the car, because the 185R15 family spans more than one acceptable rim-width range depending on the exact product.

1963 Simca tires can be appropriate for highway use when the size, condition, and speed rating match the way the car is driven. The clearest speed-rated examples are the radial sizes: 145R13 includes an H-rated Michelin option to 130 mph, 155R14 includes a T-rated Michelin option to 118 mph, and 185R15 includes H-rated Michelin versions to 130 mph plus a V-rated Michelin version to 149 mph. Bias-ply sizes for 1963 Simca should be approached with the expectations of vintage construction rather than modern high-speed touring habits.

In real collector use, the car's brakes, suspension, steering, and age often become the limiting factors before the tire does. A well-sorted 1963 Simca driven within its natural pace can be enjoyable on the road, but tire condition and correct inflation matter just as much as the sidewall code. Highway confidence comes from the whole package working together, not from reading the tire size alone.

Inflation pressure on a 1963 Simca should follow the vehicle's factory guidance first, then be checked against the tire maker's own sidewall or service information for the exact product. Some available tires include load-and-pressure references: 145R13 reaches 825 pounds at 44 psi, 155R14 reaches 990 pounds at 44 psi, 560-14 carries 906 pounds at 30 psi, and one 185R15 option carries 1355 pounds at 35 psi. Those figures are maximum load-and-pressure pairings, not blanket instructions for every Simca application.

That distinction is important because collector-car ride, handling, and tread wear can change dramatically if a tire is simply inflated to its maximum sidewall figure. Use the original owner's literature or marque guidance to establish the car's target pressure, then confirm that the chosen tire is being used within its rated range. Never transfer a pressure number from a 14-inch Simca sedan tire to a 15-inch Arlane tire or vice versa.

Before a longer drive in a 1963 Simca, inspect every tire for cracking, cuts, bulges, uneven wear, and correct inflation, then do the same for the spare. Pay close attention to valve stems and any wheel sealing concerns, especially if the car uses an older tube-type arrangement or long-stored original wheels. On the road-going side, make sure the tire size on the car matches the wheel diameter it is meant to fit, since 1963 Simca ranges from 12-inch through 15-inch applications.

Tire checks should be part of a broader pre-trip routine on any car of this age. Brakes, wheel bearings, cooling, and lighting all matter, but the tires are the only part touching the road and are often the easiest problem to spot early. If the car has been parked for a while, a short local test drive before the main trip is a smart way to confirm that the tires and the rest of the chassis are behaving normally.
