The 1962 Simca 1000 arrived as a compact European sedan from an era when small-displacement, rear-engine cars gave everyday drivers an efficient and practical alternative to larger family cars. Its simple packaging and distinctly early-1960s character make it especially appealing to collectors who want a small foreign car with authentic road manners and period style. Tire choice matters because the 1962 Simca 1000 uses either a 5.60-12 bias-ply tire or a 155R12 radial, both on 12-inch rims. That opens the door to a more traditional bias-ply presentation or a radial-based approach. The right decision depends on how closely the car is being restored, how it will be driven, and whether its wheels remain true to stock dimensions.
Which Tire Size Is Right for The 1962 Simca 1000
The 1962 Simca 1000 uses two primary tire sizes, and the choice centers on construction rather than rim diameter because both fit a 12-inch wheel. The Simca 1000 Series can be found with either a 155R12 radial or a 5.60-12 bias-ply, so the first step is deciding whether the car should retain a more period-style bias-ply setup or move toward radial construction while keeping the correct wheel diameter.
A 155R12 size uses a nominal 155-millimeter section width, radial construction, and a 12-inch rim diameter. In this format, the aspect ratio is not stated in the size itself, and it is commonly understood as an older Euro-metric radial convention. On a 1962 Simca 1000, this size suits owners who want a radial-format tire while staying with the proper 12-inch wheel. It is a useful choice to evaluate when the goal is maintaining the car's compact European tire character without shifting to a different rim diameter.
A 5.60-12 tire is a vintage numeric bias-ply size in which the first number refers to the nominal section width in inches and the final number identifies a 12-inch rim. Bias-ply construction is closely tied to the driving feel and period presentation associated with many small early-1960s cars. On the 1962 Simca 1000, this size makes sense for owners focused on traditional appearance and an era-appropriate tire format. It is the size to examine closely when restoration character matters as much as simple dimensional fitment.
Fitment is straightforward here because the covered Simca 1000 sub-model uses the same two primary tire-size paths. The key decision is not trim-level variation, but whether the car is staying with 5.60-12 bias-ply construction or using the 155R12 radial size on the same 12-inch rim diameter.

The 1962 Simca 1000 Series can use either a 155R12 radial or a 5.60-12 bias-ply tire, both built around a 12-inch rim. That gives the owner a clear choice between a more traditional bias-ply presentation and a radial-format approach, while keeping wheel diameter confirmation simple.
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.
Frequently Asked Questions
Common questions for the 1962 Simca 1000 usually center on choosing between 5.60-12 bias-ply and 155R12 radial fitment, understanding what those size codes mean, and checking wheel condition, clearance, and tire health before road use.
Tire Size & Fitment
What tire size fits a 1962 Simca 1000?
The 1962 Simca 1000 uses two primary tire sizes: 155R12 in radial construction and 5.60-12 in bias-ply construction. Both are tied to a 12-inch rim, so the main distinction is the tire format and construction style rather than a change in wheel diameter.
That means the buying decision starts with how the car is set up and how it will be used. A restoration-oriented Simca may stay with 5.60-12 for a more traditional look and feel, while a 155R12 suits owners looking for a radial-format option on the same rim diameter.
What size rim does a 1962 Simca 1000 use?
The 1962 Simca 1000 uses a 12-inch rim diameter with both of its primary tire sizes. The 155R12 radial and the 5.60-12 bias-ply are both built for 12-inch wheels, which keeps the basic wheel-diameter requirement simple.
Wheel diameter is only one part of fitment, though. Before choosing a tire, it is smart to confirm the actual wheels on the car, especially if it has been modified over the years. Wheel width, bead-seat condition, and clearance at the fenders and suspension still matter when selecting between radial and bias-ply construction.
What does 5.60-12 mean on a 1962 Simca 1000?
A 5.60-12 is a vintage numeric bias-ply size. The 5.60 refers to the nominal section width in inches, and the 12 identifies the wheel diameter in inches. It is an older sizing convention that is very different from modern metric radial sizes, but it remains familiar on many small imported cars of this era.
For a 1962 Simca 1000 owner, that size points toward a traditional bias-ply setup and a period-style appearance. It should not be confused with the 155R12 radial simply because both mount on 12-inch rims. Construction, profile, and overall tire character still need to be considered before making a change.
Bias-Ply & Radial Options
Is 5.60-12 a bias-ply or radial tire for the 1962 Simca 1000?
On the 1962 Simca 1000, 5.60-12 is a bias-ply tire size. It uses the older numeric sizing system and represents the traditional construction style associated with many early-1960s compact vehicles, especially when period-style presentation is part of the goal.
That matters because a bias-ply tire changes the selection process compared with a radial. The owner should confirm the wheel condition and overall vehicle setup before choosing between 5.60-12 and 155R12, since keeping a bias-ply tire often aligns more closely with restoration-minded priorities than simply switching constructions for convenience.
Should I use bias-ply or radial tires on a 1962 Simca 1000?
Either can be appropriate for a 1962 Simca 1000 because both a 5.60-12 bias-ply and a 155R12 radial are used on this model. Bias-ply tires support a more traditional period presentation, while the radial size gives the owner a modern tire construction format within the same 12-inch rim diameter.
The better choice depends on the car's purpose. A restoration-focused Simca may call for the visual character of a bias-ply tire, while a driver-oriented car may lead the owner toward the radial size. Before changing construction, verify the actual wheel setup, check clearance, and make sure the car's suspension and steering components are in sound condition.
What should I check before converting my 1962 Simca 1000 from bias-ply to radial tires?
Start by confirming that the car is using the correct 12-inch wheels and that the intended radial size is 155R12. Because the Simca 1000 also uses a 5.60-12 bias-ply option, the change is not just about mounting another tire; it is a shift in sizing convention and construction.
Wheel width, wheel condition, and clearance should all be checked before making the move. It is also wise to inspect steering parts, suspension components, and alignment condition so the car is ready for regular road use. On an older imported car, a radial conversion works best when the complete wheel-and-chassis setup is evaluated first.
Choosing the Right Tire
What should I consider when choosing a 5.60-12 tire for a 1962 Simca 1000?
A 5.60-12 choice starts with confirming that the car is being kept in its bias-ply tire format. That size suits a 1962 Simca 1000 owner who wants a traditional numeric tire designation and the period-style look and character associated with older compact European cars.
After confirming the size, focus on the condition and dimensions of the wheels already on the car. A bias-ply selection is often driven by restoration goals, but it still needs to match the vehicle's actual setup. Clearance, wheel condition, and the intended mix of display use and road use should guide the final choice.
What should I consider when choosing a 155R12 tire for a 1962 Simca 1000?
Choosing a 155R12 tire for a 1962 Simca 1000 means selecting the radial-format option used on this model. The size keeps the car on a 12-inch rim while moving into an older Euro-metric radial convention, which appeals to owners who want radial construction without changing wheel diameter.
The practical step is confirming that the car's wheels and overall setup are appropriate for that radial size. A Simca that has seen wheel changes over time may need closer inspection before a tire is selected. It also helps to decide whether the car's priority is road use, appearance, or preserving a more traditional period presentation.
How do I choose between the available 1962 Simca 1000 tires?
The main choice on a 1962 Simca 1000 is between two different tire approaches rather than between many product variations. A 5.60-12 bias-ply serves the owner who wants a traditional vintage tire format, while a 155R12 gives the car a radial-format tire on the same 12-inch wheel diameter.
A good way to decide is to start with the car's purpose. A restoration or show-oriented Simca may point toward the bias-ply size, while a more regularly driven car may make the radial size more attractive. In either case, the actual wheel setup and surrounding clearance should be checked before committing to a set.
Restoration & Appearance
Which tire should I choose for a period-style 1962 Simca 1000?
For a period-style 1962 Simca 1000, the 5.60-12 bias-ply size is the natural starting point because it uses the vintage numeric format associated with the car's era. That does not automatically make every bias-ply tire historically exact, but it aligns closely with a traditional early-1960s small-car presentation.
Appearance is only part of the decision, so the wheels on the car still need to be checked before any purchase. Owners pursuing exact restoration standards should compare the chosen size and tire style against marque references or period documentation, especially if the goal goes beyond a general period-style look and toward higher historical accuracy.
How does tire construction affect the appearance of a restored 1962 Simca 1000?
Tire construction changes the overall visual character of a restored 1962 Simca 1000. A 5.60-12 bias-ply gives the car a more traditional vintage presentation, while a 155R12 radial introduces a later-style tire format even though it still fits the correct 12-inch wheel diameter.
That difference can be important on a small European sedan where tire shape and stance are easy to notice. Owners focused on restoration appearance often start with the bias-ply option, while those balancing appearance with regular road use may consider the radial route. The best match depends on how original the finished car is meant to appear.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1962 Simca 1000?
Yes, modifications can affect tire fitment on a 1962 Simca 1000 even though both primary tire sizes use a 12-inch rim. Aftermarket wheels, changed wheel widths, altered ride height, suspension work, or body modifications can all influence how a 5.60-12 bias-ply or 155R12 radial fits the car.
That is why the actual vehicle should be checked rather than assuming every Simca remains in original configuration. Steering clearance, fender clearance, and wheel condition all deserve attention before replacing tires. Older imported cars often pass through several owners, so verifying what is currently on the car is part of safe fitment planning.
What should I inspect before driving a 1962 Simca 1000 on new tires?
Before driving a 1962 Simca 1000 on new tires, inspect the wheels for damage or corrosion, confirm that the tire size matches the intended setup, and make sure the tires are seated properly. It is also smart to check for any obvious suspension or steering wear that could affect how the car tracks on the road.
Collector cars often sit for long periods, so basic condition checks matter as much as the tire purchase itself. Look over sidewalls and tread after installation, verify inflation, and make sure there is no rubbing at full steering lock or under suspension movement. A cautious short drive is a good way to confirm everything feels settled.
How should tires on a collector 1962 Simca 1000 be maintained?
Tires on a collector 1962 Simca 1000 should be inspected regularly for cracking, cuts, bulges, uneven wear, and loss of air pressure. That applies whether the car is using 5.60-12 bias-ply tires or 155R12 radials, since age and storage conditions can affect both types even when mileage is low.
Good maintenance also includes keeping the car stored away from prolonged sunlight, excess moisture, and ozone-producing equipment when possible. Periodic pressure checks and visual inspection before each outing are especially important on lightly used cars. A small vintage sedan can feel very different on neglected tires, even if the tread still appears usable.
