The 1965 Simca 1000 belongs to an era when compact European cars delivered efficient packaging, light weight, and distinctive character in a small footprint. For enthusiasts today, that makes tire choice especially important because the car’s proportions and stance are closely tied to the right wheel-and-tire combination. Fitment on the 1965 Simca 1000 varies by sub-model, with the Bertone Coupe using 13-inch fitments and the Series using 12-inch fitments, in either radial or bias-ply form. Available radial choices for 145R13 include Michelin and Firestone blackwall tires. Whether the goal is road use or a more restoration-oriented presentation, confirming the exact sub-model and wheel diameter comes first.
Which Tire Size Is Right for The 1965 Simca 1000
The 1965 Simca 1000 uses four primary tire sizes across two sub-model groups, and the first step is identifying whether the car is a Bertone Coupe or a Series model. Wheel diameter matters just as much, since these fitments are split between 13-inch and 12-inch rims and include both radial and bias-ply constructions. Once that is confirmed, the decision becomes choosing the right construction and tire style for the way the car will be used.
A 145R13 is a Euro-metric radial size with a nominal section width of 145 millimeters, radial construction, and a 13-inch rim diameter. On the 1965 Simca 1000, this size is used on the Bertone Coupe and gives buyers a modern radial-format option within the car’s proper fitment range. Available products in this size include blackwall tires from Michelin and Firestone, with series such as Michelin XAS-FF and Firestone F560 Radial. It is a strong size to evaluate when the goal is 13-inch fitment with radial construction and a traditional small-car appearance.
A 5.50-13 is a numeric bias-ply size in which the leading number refers to nominal section width in inches and the final number identifies a 13-inch rim. For the 1965 Simca 1000, this size is part of the Bertone Coupe fitment and reflects the earlier bias-ply sizing system many vintage European cars used. Bias-ply construction appeals to owners who want a more traditional tire type and period-style driving character. It is the size to consider when retaining the Coupe’s 13-inch wheel diameter while staying closer to an earlier-style construction approach.
A 155R12 is a Euro-metric radial tire with a nominal section width of 155 millimeters and a 12-inch rim diameter. On the 1965 Simca 1000, this size belongs to the Series models and should not be confused with the 13-inch Bertone Coupe fitments. Radial construction makes this an important size for owners who want to keep the Series on its correct wheel diameter while using a metric radial format. Before choosing it, confirm that the car still carries the proper 12-inch wheels and has not been changed to a different wheel setup over time.
A 5.60-12 is a numeric bias-ply tire size, with the first number indicating approximate nominal section width in inches and the last number indicating a 12-inch rim. This is one of the primary fitments for the 1965 Simca 1000 Series and represents the bias-ply alternative within that sub-model group. Its appeal is usually tied to traditional sizing, vintage appearance, and a more period-style construction choice. It is the right size to evaluate when the car is a Series model on 12-inch wheels and the owner wants to preserve that earlier tire format.
Sub-model fitment on the 1965 Simca 1000 is not interchangeable across the board, because the covered versions use different wheel diameters and tire sizes. Checking whether the car is a Bertone Coupe or a Series model is the key step before comparing radial and bias-ply options.

1965 Simca 1000 Bertone Coupe
The 1965 Simca 1000 Bertone Coupe uses 13-inch fitments, with both 145R13 radial and 5.50-13 bias-ply sizes associated with this sub-model. That gives the Coupe owner a clear construction choice, but the decision still needs to stay anchored to the car’s existing wheels and intended appearance.
The 1965 Simca 1000 Series uses 12-inch fitments, pairing either 155R12 radial or 5.60-12 bias-ply sizing with this sub-model. For tire selection, that means wheel diameter confirmation comes first, followed by choosing between a more traditional bias-ply presentation and a radial-format alternative.
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.

Tire Size & Fitment
What tire size fits a 1965 Simca 1000?
A 1965 Simca 1000 can use more than one primary tire size, depending on the sub-model. 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 means the correct answer starts with identifying the exact version of the car and confirming the wheel diameter actually on it today. A 12-inch Series fitment and a 13-inch Bertone Coupe fitment are not the same decision, and any car that has been changed over the years should be measured before a tire is selected.
What size rim does a 1965 Simca 1000 use?
The 1965 Simca 1000 uses either a 13-inch or 12-inch rim, depending on the sub-model and tire size. Bertone Coupe fitments are tied to 13-inch sizes, while Series fitments are tied to 12-inch sizes.
Rim diameter is the first fitment checkpoint because it determines which tire group even belongs on the car. After that, wheel width and the overall wheel setup should be checked as well, especially if the car has been in collector use for years or has received replacement wheels at some point in its life.
Why does the 1965 Simca 1000 have more than one tire size?
The 1965 Simca 1000 shows more than one tire size because different sub-models use different wheel diameters, and each sub-model is also represented in both radial and bias-ply sizing. The Bertone Coupe uses 13-inch fitments, while the Series uses 12-inch fitments.
That split means the buyer is not simply choosing between four interchangeable sizes. The real task is matching the car’s exact sub-model and wheel diameter first, then deciding whether the intended result is a traditional bias-ply setup or a radial configuration that still stays within the correct size family.
Choosing the Right Tire
What should I consider when choosing a 145R13 tire for a 1965 Simca 1000?
A 145R13 belongs to the 1965 Simca 1000 Bertone Coupe and should be chosen only for a car using the correct 13-inch wheel setup. Within that size, the available radial products differ by brand, tire series, weight, and whether a rim-width specification is stated.
Practical selection comes down to how the car will be used and how closely the owner wants to stay with a traditional small European radial look. Comparing details such as blackwall presentation, construction, and wheel compatibility helps narrow the choice without drifting into a different diameter or construction that changes the fitment discussion.
What sidewall styles are available for 1965 Simca 1000 tires?
Among the currently available 145R13 products for the 1965 Simca 1000, the sidewall style is blackwall. That keeps the presentation simple and very much in line with the understated look many compact European cars of the period wore on the road.
Sidewall style affects appearance as much as fitment, especially on a small car where the tire is visually prominent against a modest wheel diameter. Even so, sidewall preference should be considered only after the buyer has confirmed the correct sub-model, the correct 12-inch or 13-inch wheel, and the intended radial or bias-ply direction.
What brands offer tires for the 1965 Simca 1000?
For the 145R13 fitment used on the 1965 Simca 1000 Bertone Coupe, available radial tire brands include Michelin and Firestone. Their offerings in this size include series such as Michelin XAS-FF and Firestone F560 Radial.
Brand choice is only one part of the decision, because the tire still has to match the car’s correct size, wheel diameter, and intended use. It also helps to compare specification details such as rim-width guidance where stated, construction, and overall presentation so the selected tire suits both the car’s setup and the owner’s goals.
Restoration & Appearance
Which tire should I choose for a period-style 1965 Simca 1000?
A period-style 1965 Simca 1000 tire choice starts with the correct sub-model fitment and wheel diameter. The Bertone Coupe uses 13-inch sizes and the Series uses 12-inch sizes, with each sub-model represented in both radial and bias-ply form, so the construction choice shapes the final look.
Bias-ply sizing often supports a more traditional presentation, while a metric radial can preserve the proper fitment family with a different visual and road-use character. When exact originality matters, it is worth checking marque-specific historical references so the selected size and sidewall treatment align with the restoration standard being pursued.
Does correct tire fitment matter for a 1965 Simca 1000 restoration?
Correct tire fitment matters a great deal on a 1965 Simca 1000 because the car’s small dimensions make wheel diameter and tire proportions especially noticeable. Using the proper 12-inch or 13-inch fitment for the exact sub-model helps preserve the car’s stance, visual balance, and overall period character.
A restoration-oriented choice should begin with the right size family before considering brand or construction. Even a tasteful tire can look out of place if the wheel diameter is wrong or the sub-model fitment is mixed up, so the owner should verify the existing wheels carefully before trying to refine appearance details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1965 Simca 1000?
Yes, modifications can affect tire fitment on a 1965 Simca 1000, especially if the car has different wheels, altered ride height, or suspension changes. Those changes matter more here because the car’s original fitments are already split between 12-inch and 13-inch wheel diameters by sub-model.
Any car that has been updated should have its actual wheel diameter and width checked before a tire is chosen. Steering clearance, fender space, and the relationship between tire size and wheel width are all worth reviewing so the selected tire suits the car as it sits now, not just as it may have left the factory.
What should I inspect before driving a 1965 Simca 1000 on new tires?
Before driving a 1965 Simca 1000 on new tires, inspect the wheels for correct diameter and condition, then check that the tires are properly seated and inflated. It also makes sense to look over the suspension, steering components, and alignment condition so the new tires are not being asked to work around an existing problem.
A short test drive should be followed by another walk-around to confirm stable air pressure and no signs of rubbing or unusual wear. On a lightly used collector car, it is also wise to inspect brake function, wheel hardware, and general roadworthiness at the same time, since tire replacement often coincides with putting the car back into regular motion.
What should I check before a longer drive in a 1965 Simca 1000?
Before a longer drive in a 1965 Simca 1000, check tire pressure, tread condition, visible sidewall condition, and any signs of air loss. The right sub-model fitment matters here as well, because a Bertone Coupe on 13-inch tires and a Series on 12-inch tires should each be running the correct size family for the wheels installed.
A longer outing is also a good reason to confirm that the spare, jack, and wheel hardware are usable. Collector cars often spend time parked, so cracking, flat spotting, or age-related deterioration can appear even when tread looks decent, making a careful pre-drive inspection just as important as choosing the correct tire size.
