The 1964 Simca 1000 belongs to a period when compact European cars emphasized efficiency, light weight, and tidy dimensions rather than excess size. That makes tire fitment especially important, because this exact model can be found with either 12-inch or 13-inch wheel setups depending on sub-model. The Bertone Coupe uses 145R13 radial or 5.50-13 bias-ply sizing, while the Series uses 155R12 radial or 5.60-12 bias-ply sizing. Available product choice centers on the 145R13 radial, with Michelin and Firestone blackwall options in distinct series. Before choosing a tire, the key step is confirming the exact sub-model and wheel diameter already on the car.
Which Tire Size Is Right for The 1964 Simca 1000
The 1964 Simca 1000 uses four primary tire sizes across two different sub-model and wheel-diameter combinations. The first step is identifying whether the car is a Bertone Coupe or a Series model, then confirming whether it is running the 13-inch or 12-inch setup, since both radial and bias-ply fitments appear within the covered range.
145R13 is a Euro-metric radial size in which 145 identifies nominal section width in millimeters, R indicates radial construction, and 13 is the wheel diameter in inches. On the 1964 Simca 1000, this size is tied to the Bertone Coupe and gives that sub-model a radial-format fitment on a 13-inch rim. Available choices include Michelin and Firestone blackwall tires in the Michelin XAS-FF and F560 Radial series. This size is the right place to start when the car retains its 13-inch Coupe wheel setup and a radial construction is desired.
5.50-13 is a numeric bias-ply size, with 5.50 referring to the nominal section width in inches and 13 indicating a 13-inch rim. This is the bias-ply fitment associated with the 1964 Simca 1000 Bertone Coupe, making it relevant for owners who want to stay with a traditional construction and period-style sizing format. Its significance is less about modern tire notation and more about preserving the original-era look and driving character of a small European coupe. Confirming that the car still uses the 13-inch Coupe wheel package is essential before selecting this size.
155R12 is a Euro-metric radial size where 155 gives the nominal width in millimeters, R marks radial construction, and 12 identifies the wheel diameter in inches. On the 1964 Simca 1000, this radial size belongs to the Series model rather than the Bertone Coupe, so it should not be treated as a universal fitment across all versions. The smaller rim diameter makes wheel confirmation especially important here, since a 12-inch setup changes the starting point entirely. This size suits a Series model that is using the radial-format fitment on its correct wheel diameter.
5.60-12 is a numeric bias-ply tire size, with the first number expressing nominal section width in inches and the second number identifying a 12-inch wheel. For the 1964 Simca 1000, this bias-ply fitment is associated with the Series model and reflects a traditional construction on the smaller wheel package. Buyers looking at this size are usually deciding whether to keep a period-style bias-ply presentation or compare it against the Series model's radial-size path. The important check is that the car is in fact a Series and that its wheels remain the correct 12-inch diameter.
Sub-model fitment matters on the 1964 Simca 1000 because the covered versions do not share the same tire size or wheel diameter. The Bertone Coupe and the Series follow different 13-inch and 12-inch tire paths, so identifying the exact sub-model comes before comparing tires.

1964 Simca 1000 Bertone Coupe
The 1964 Simca 1000 Bertone Coupe uses the 13-inch fitment family, with both radial and bias-ply sizing represented. That means tire selection starts with confirming whether the car is being kept in a more traditional bias-ply format or fitted with the radial-size option on its correct wheel diameter.
The 1964 Simca 1000 Series uses the 12-inch fitment family rather than the Coupe's 13-inch setup, and both radial and bias-ply sizes appear within that smaller wheel diameter. Tire choice here depends on keeping the Series wheel configuration straight before comparing construction type or overall presentation.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1964 Simca 1000 Tires for Sale
Available products center on the 145R13 radial fitment for the 1964 Simca 1000 Bertone Coupe. Buyers can compare Michelin and Firestone blackwall radials across the Michelin XAS-FF and F560 Radial series, with differences in rim-width specification, load information, and tire weight.
Owners usually need to sort out sub-model, wheel diameter, and whether the car is staying with bias-ply sizing or moving within its radial fitment path. The questions below focus on exact Simca 1000 tire size, rim fitment, product choice, appearance, and road-use checks.
Tire Size & Fitment
What tire size fits a 1964 Simca 1000?
The 1964 Simca 1000 does not use one universal tire size across every covered version. The Bertone Coupe uses 145R13 in radial form or 5.50-13 in bias-ply form, while the Series uses 155R12 in radial form or 5.60-12 in bias-ply form.
That makes sub-model identification the first step before comparing brands or construction. A Coupe and a Series do not start from the same wheel diameter, so checking the car's actual wheels is just as important as reading the sidewall size, especially if the car has been changed over the years.
What size rim does a 1964 Simca 1000 use?
A 1964 Simca 1000 can use either a 13-inch or 12-inch rim depending on the sub-model. The Bertone Coupe follows the 13-inch tire sizes, while the Series follows the 12-inch tire sizes.
Rim diameter has to be confirmed before any tire is selected because a 12-inch and 13-inch setup are not interchangeable starting points. Looking at the wheel already on the car, verifying the sidewall size, and checking that the vehicle still carries its intended sub-model wheel package will prevent ordering the wrong fitment.
Why does the 1964 Simca 1000 have more than one tire size?
More than one tire size appears because the 1964 Simca 1000 range includes different sub-models with different wheel-diameter families, and each of those sub-models can also appear in either radial or bias-ply sizing. The Bertone Coupe uses 13-inch sizes, while the Series uses 12-inch sizes.
The practical takeaway is that tire choice should not begin with brand or tread alone. Start by confirming whether the car is a Bertone Coupe or a Series model, then verify the wheel diameter actually fitted to the car now, since a long-owned or restored vehicle may not still be wearing its original-style wheel setup.
Choosing the Right Tire
What should I consider when choosing a 145R13 tire for a 1964 Simca 1000?
A 145R13 tire is relevant to the 1964 Simca 1000 Bertone Coupe, so the first considerations are sub-model confirmation, radial construction preference, and correct 13-inch wheel diameter. Within that size, available options include Michelin and Firestone blackwall radials in different tire series.
Selection then becomes a matter of matching the tire to the car's intended use and wheel setup. Comparing rim-width guidance where available, tire weight, and load information can be helpful, especially on a small, light European car where fitment balance matters and owners may want either a more restoration-oriented presentation or a straightforward road-use choice.
What sidewall styles are available for 1964 Simca 1000 tires?
The available 145R13 product choices for the 1964 Simca 1000 Bertone Coupe are offered in blackwall form. That gives the car a clean, understated sidewall presentation consistent with many compact European tire choices of the period.
Sidewall style matters because it changes the visual character of a small car more than many owners expect. Even when the tire size is correct, the overall look can shift noticeably, so it is worth deciding early whether the goal is a simple roadgoing appearance or a more restoration-minded presentation built around the car's compact European proportions.
What brands offer tires for the 1964 Simca 1000?
For the 145R13 radial fitment used on the 1964 Simca 1000 Bertone Coupe, available brands include Michelin and Firestone. Those choices appear in the Michelin XAS-FF and Firestone F560 Radial series, both in blackwall form.
Brand choice should still come after the basic fitment checks. Make sure the car is the Bertone Coupe, confirm the 13-inch wheel setup, and then compare the available series by construction details, rim-width guidance where stated, and the kind of appearance and driving use the car is expected to see rather than choosing by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1964 Simca 1000?
A period-style approach starts with using the correct sub-model size family and wheel diameter. For the 1964 Simca 1000 Bertone Coupe that means the 13-inch path, while the Series follows the 12-inch path, and each sub-model also has both bias-ply and radial size formats associated with it.
Owners focused on a more traditional presentation often look closely at whether to keep a bias-ply format such as 5.50-13 or 5.60-12, while others prefer the visual restraint of a Euro-metric radial. When exact originality matters, the final decision should be checked against marque references, period photos, or restoration records for the specific car.
Does correct tire fitment matter for a 1964 Simca 1000 restoration?
Correct tire fitment matters because the 1964 Simca 1000 spans two distinct wheel-diameter families and more than one sizing convention. A restoration that uses the wrong 12-inch or 13-inch fitment can change the car's stance, proportions, and overall visual balance even before the car is driven.
Construction choice also affects appearance. A bias-ply size presents the car differently from a Euro-metric radial, so restoration-minded owners usually begin with the right sub-model and wheel diameter, then decide how closely they want to follow a traditional look versus selecting a tire that better suits regular road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1964 Simca 1000?
Yes, modifications can affect tire fitment on a 1964 Simca 1000, especially because this model already spans both 12-inch and 13-inch wheel setups across its sub-models. Aftermarket wheels, altered ride height, brake changes, or previous restoration work can all change the starting point from the original-size family.
That means the tire sidewall should not be the only thing checked. Measure the actual wheel diameter, confirm wheel width, and inspect for clearance at the fender, suspension, and steering range before changing size or construction, particularly if the car has passed through multiple owners or long-term project phases.
What should I inspect before driving a 1964 Simca 1000 on new tires?
Before driving a 1964 Simca 1000 on new tires, inspect the wheels for correct diameter and condition, verify that the chosen tire matches the car's sub-model fitment, and make sure the valve stems, mounting surfaces, and inflation are all in good order. Basic clearance should also be checked at full steering lock.
A low-mileage collector car deserves extra attention beyond the tires themselves. Look over suspension bushings, wheel bearings, brakes, and alignment condition, since aged components can affect how a freshly mounted tire behaves on the road and may create wear or handling issues that seem like tire problems at first.
How should tires on a collector 1964 Simca 1000 be maintained?
Tires on a collector 1964 Simca 1000 should be maintained with regular pressure checks, visual inspections for cracking, bulges, cuts, and uneven wear, and periodic confirmation that the car is still carrying the correct sub-model size. Collector cars often age their tires through time and storage as much as through mileage.
Storage conditions matter almost as much as road use. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve the tire casing, and moving the vehicle occasionally can help avoid long-term flat spotting. Any sign of persistent air loss or sidewall deterioration deserves immediate professional inspection.
