The 1983 Fiat 124 sits at the end of a long-running Italian sports-car line that remained appealing for its compact proportions, open-top character, and lively road manners. For many owners, tire choice shapes both the car’s stance and the way it feels on the road as much as any other maintenance item. This Fiat 124 uses radial tires, with both 165R13 and 185/60R14 fitments appearing on the Spider. Available choices lean toward blackwall radials from Michelin and Dunlop, spanning traditional Euro-metric sizing and a lower-profile modern metric option. The key is confirming which wheel diameter is on the car before choosing between period-style presentation and a more contemporary 14-inch setup.
Which Tire Size Is Right for The 1983 Fiat 124
Two tire sizes apply to the 1983 Fiat 124, and the first step is confirming which wheel diameter your car actually has. The Spider appears with either a 13-inch radial fitment or a 14-inch radial fitment, so tire selection starts with the installed wheel rather than brand alone. Once that is confirmed, the decision shifts to sizing style, overall appearance, and the character of the available tire options.
A 185/60R14 is a metric radial size with a 185-millimeter section width, a 60-series aspect ratio, and a 14-inch rim diameter. Compared with an older Euro-metric sizing convention, this format reflects a lower-profile modern radial approach tied to a different wheel diameter. For the 1983 Fiat 124, the available product in this size is a blackwall Michelin Pilot Exalto PE2. It is the size to evaluate when the car is already equipped with 14-inch wheels and the goal is matching that wheel setup with the correct modern metric radial format.
Sub-model fitment is straightforward here, but wheel setup still matters. The 1983 Fiat 124 Spider appears with both applicable tire sizes, so confirming whether the car is on 13-inch or 14-inch wheels is more important than the sub-model name itself.

1983 Fiat 124 Spider
The 1983 Fiat 124 Spider can use either radial fitment associated with this model year, depending on the wheel diameter installed on the car. That means tire selection starts by confirming the actual wheel setup, then choosing between a taller-profile 13-inch Euro-metric radial and a 14-inch modern metric radial option.
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 1983 Fiat 124 Tires for Sale
Available 1983 Fiat 124 tire choices center on blackwall radials from Michelin and Dunlop. The product mix includes Michelin XAS and XAS-FF in 165R13, Dunlop SP Sport Aquajet in the same 13-inch size, and Michelin Pilot Exalto PE2 in 185/60R14.
Common 1983 Fiat 124 tire questions usually come down to size, wheel diameter, radial fitment, and how to choose between traditional 13-inch options and the 14-inch alternative. Owners also tend to ask about appearance, maintenance, and what to inspect before regular road use.
Tire Size & Fitment
What tire size fits a 1983 Fiat 124?
The 1983 Fiat 124 uses two radial tire sizes: 165R13 and 185/60R14. On the covered sub-model, the Fiat 124 Spider, either size can apply, so the car is not limited to one universal tire size across every wheel setup.
The important next step is checking the wheel diameter that is actually on the car. A 165R13 belongs on a 13-inch wheel, while a 185/60R14 belongs on a 14-inch wheel, and that difference affects which tires you can consider. If the car has been changed from its earlier wheel setup, verify the current wheels before selecting a tire.
What size rim does a 1983 Fiat 124 use?
The 1983 Fiat 124 appears with two rim diameters: 13 inches and 14 inches. The 165R13 tire size uses a 13-inch rim, and the 185/60R14 tire size uses a 14-inch rim.
That makes rim confirmation the first fitment check before comparing brands or tire series. Looking only at the car’s model name is not enough, because the Spider can appear with either wheel diameter. Measure the wheel or confirm the wheel stampings if there is any doubt, especially on a car that may have had wheels changed over time.
Why does the 1983 Fiat 124 have more than one tire size?
More than one tire size appears on the 1983 Fiat 124 because the car can be found with different wheel diameters. In this case, the Spider uses either a 165R13 radial on a 13-inch wheel or a 185/60R14 radial on a 14-inch wheel.
That means the right choice depends on the wheel setup currently fitted to the car, not simply the model year. A buyer should confirm whether the Fiat still carries its existing 13-inch arrangement or has been changed to 14-inch wheels. Once that is established, the tire decision becomes much easier and the available product options narrow to the correct size.
Choosing the Right Tire
What should I consider when choosing a 165R13 tire for a 1983 Fiat 124?
A 165R13 tire for a 1983 Fiat 124 should first match the car’s 13-inch wheel diameter and the Euro-metric radial sizing format used on that setup. Within that size, available choices include Michelin XAS, Michelin XAS-FF, and Dunlop SP Sport Aquajet, all in blackwall form.
After confirming the wheel size, compare the tire series and the wheel-width range when it is stated for the product. This size tends to appeal to owners who want a more traditional presentation on the Fiat’s 13-inch wheels, so the decision often comes down to the character of the tire line rather than sidewall style, since the available options are blackwall.
What brands offer tires for the 1983 Fiat 124?
Tires for the 1983 Fiat 124 are available from Michelin and Dunlop. Michelin covers both supported sizes here, with XAS and XAS-FF options in 165R13 and a Pilot Exalto PE2 option in 185/60R14, while Dunlop appears in 165R13 with the SP Sport Aquajet.
Brand choice should come after the correct size and wheel diameter are confirmed. Once that is settled, compare each brand’s available tire series, sizing format, and any stated rim-width details that apply to your wheel. The practical difference on this Fiat is less about brand prestige and more about whether the tire matches the car’s 13-inch or 14-inch setup.
What tire series are available for the 1983 Fiat 124?
The 1983 Fiat 124 is served by several distinct tire series, including Michelin XAS, Michelin XAS-FF, Dunlop SP Sport Aquajet, and Michelin Pilot Exalto PE2. The first three belong to the 165R13 fitment, while the Pilot Exalto PE2 is the available option in 185/60R14.
That matters because the choice is not simply between brands; it is also between different tire lines within the correct size. Owners staying with 13-inch wheels can compare multiple series in 165R13, while the 14-inch setup points directly to the 185/60R14 offering. Pick the tire series only after confirming the wheel diameter and desired overall look of the car.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Fiat 124?
For a period-style 1983 Fiat 124, the 165R13 radial is usually the most traditional-looking starting point because it keeps the car in an older Euro-metric 13-inch sizing format. Michelin XAS, Michelin XAS-FF, and Dunlop SP Sport Aquajet all fall into that 165R13 group.
The right choice still depends on the wheels that are actually on the car. A Fiat 124 already equipped with 14-inch wheels should be matched to the proper 185/60R14 fitment instead of chasing a smaller-diameter look. When exact restoration detail matters, it is smart to compare the car against marque references or model-specific historical material before settling on a final tire presentation.
How does tire construction affect the appearance of a restored 1983 Fiat 124?
On the 1983 Fiat 124, the covered fitments are radial, so the appearance question is more about sizing format and wheel diameter than a bias-ply-versus-radial choice. A 165R13 radial gives the car a taller-profile, more traditional small-wheel presentation, while a 185/60R14 brings a lower-profile modern metric look.
That visual difference can change the stance of the car even before the Fiat turns a wheel. Owners restoring for a broadly period-style appearance often focus on preserving the wheel-and-tire relationship that suits the car’s era, while owners aiming for a more updated look may favor the 14-inch setup. Either way, matching the tire to the installed wheel remains the first requirement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Fiat 124?
Modifications can absolutely affect tire fitment on a 1983 Fiat 124. Wheel changes, altered offsets, suspension lowering, spring changes, or body modifications can all influence whether a 165R13 or 185/60R14 setup has proper clearance during steering and suspension movement.
A modified Fiat should be checked at the wheel and fender level rather than assumed to match stock fitment behavior. Turn the steering from lock to lock, inspect clearance at the inner fender and suspension, and confirm the actual wheel diameter before ordering tires. Those checks matter even more on older sports cars that may have had decades of owner changes.
What should I inspect before driving a 1983 Fiat 124 on new tires?
Before driving a 1983 Fiat 124 on new tires, inspect the wheels for damage, confirm that the tire size matches the wheel diameter, and make sure the tires seat properly and hold pressure. It is also wise to check for rubbing points, loose suspension parts, and uneven wear patterns left by the previous tires.
An older roadster benefits from a broader once-over before regular use. Look at tread and sidewall condition on any remaining older spare, verify lug hardware condition, and make sure the steering and suspension feel stable on the road. A short initial drive followed by another visual inspection can help catch clearance or inflation issues before longer trips.
How should tires on a collector 1983 Fiat 124 be maintained?
Tires on a collector 1983 Fiat 124 should be checked regularly for pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Low-mileage use does not prevent aging, and a lightly used Fiat can still end up with tires that look decent but are no longer roadworthy.
Storage conditions matter almost as much as mileage on a classic convertible. Keep the car away from prolonged heat, direct sunlight, moisture, and ozone sources when possible, and inspect the tires before each driving season or longer outing. Maintaining the correct size on the correct wheel is only part of the picture; condition and age deserve equal attention.
