The 2020 Fiat 124 Spider blends classic Italian roadster character with modern compact sports-car packaging, giving buyers a lightweight rear-drive convertible that still rewards close attention to wheel and tire setup. For this model year, tire fitment depends on sub-model, with 195/50R16 and 205/45R17 radial sizes both used on the 124 Spider. That makes the real decision less about old bias-ply versus radial construction and more about confirming the exact trim, wheel diameter, and the kind of tire presentation you want. Available choices range from performance-oriented blackwall radials to a wide whitewall option, so appearance and intended use both matter before replacing tires.
Which Tire Size Is Right for The 2020 Fiat 124 Spider
The 2020 Fiat 124 Spider uses two primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. Both fitments are radial, but they are split between 16-inch and 17-inch rims, so confirming the current wheel setup is the first step before comparing tire style, series, or road-use priorities.
A 205/45R17 tire is a metric radial size with a 205-millimeter nominal section width, a 45-series profile, and a 17-inch rim diameter. On the 2020 Fiat 124 Spider, this size is used on 17-inch-wheel sub-models and keeps the fitment in a modern low-profile radial format. Available choices in this size center on BFGoodrich blackwall performance-oriented lines, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This is the size to evaluate when the car already carries the correct 17-inch wheels and the goal is a sportier modern presentation.
A 195/50R16 tire is a metric radial size with a 195-millimeter nominal section width, a 50-series profile, and a 16-inch rim diameter. On the 2020 Fiat 124 Spider, this size belongs to the 16-inch-wheel fitment rather than the 17-inch setup used elsewhere in the range. The available product choice here is a BFGoodrich Silvertown Radial with a 2-inch wide whitewall, giving this modern radial size a more distinctive visual character than the blackwall 17-inch options. It deserves a close look when preserving the correct 16-inch wheel setup is the first priority.
Tire fitment varies across the 2020 Fiat 124 Spider lineup, so identifying the exact sub-model matters before selecting a replacement tire. The main split is between the 16-inch Classica setup and the 17-inch fitment used by the other covered trims.

2020 Fiat 124 Spider Abarth
The 2020 Fiat 124 Spider Abarth uses the 205/45R17 radial tire size. That keeps tire selection focused on the correct 17-inch wheel fitment and on choosing among the available blackwall BFGoodrich performance-oriented series in that size.
The 2020 Fiat 124 Spider Classica uses the 195/50R16 radial tire size rather than the 17-inch setup found on the other sub-models. Tire selection here starts with confirming the 16-inch wheels, then deciding whether the available wide whitewall presentation suits the car's intended appearance.
The 2020 Fiat 124 Spider Lusso uses the 205/45R17 radial tire size. That means replacement shopping centers on maintaining the proper 17-inch-wheel fitment and comparing the available blackwall tire series for the balance of appearance and road use you want.
The 2020 Fiat 124 Spider Urbana uses the 205/45R17 radial tire size. The practical decision is not between multiple primary sizes, but between the available 17-inch blackwall radial options and the wheel compatibility details that go with them.
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 2020 Fiat 124 Spider Tires for Sale
Available 2020 Fiat 124 Spider tire choices center on BFGoodrich radials. The 205/45R17 fitment offers several blackwall g-Force series options with 6.5- to 7.5-inch rim-width specifications, while 195/50R16 is represented by a Silvertown Radial with a wide whitewall presentation.
These 2020 Fiat 124 Spider tire FAQs focus on the two factory-size fitments, sub-model differences, 16-inch versus 17-inch wheel confirmation, available BFGoodrich tire choices, appearance considerations, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2020 Fiat 124 Spider?
A 2020 Fiat 124 Spider uses one of two radial tire sizes: 195/50R16 or 205/45R17. The correct size depends on sub-model. The Classica uses 195/50R16, while the Abarth, Lusso, and Urbana use 205/45R17.
The first thing to confirm is the actual wheel diameter on the car, because these sizes are tied to different rim diameters. A 16-inch tire does not belong on a 17-inch wheel, and vice versa, so trim level and current wheel setup should both be verified before choosing a replacement.
What size rim does a 2020 Fiat 124 Spider use?
The 2020 Fiat 124 Spider uses either a 16-inch or 17-inch rim, depending on sub-model. The 195/50R16 fitment uses a 16-inch rim, and the 205/45R17 fitment uses a 17-inch rim.
That distinction matters because the wheel diameter determines which tire size can be mounted at all. If the car has had wheel changes since new, checking the stamping on the wheel or reading the existing tire size is a smart step before ordering, especially on used or modified examples.
Do all 2020 Fiat 124 Spider sub-models use the same tire size?
No. The 2020 Fiat 124 Spider Classica uses 195/50R16, while the Abarth, Lusso, and Urbana use 205/45R17. Both are radial sizes, but they belong to different wheel diameters and are not the same fitment across the lineup.
That means the sub-model is more than a trim detail when shopping for tires. A buyer looking at a Classica should stay focused on the 16-inch setup, while the other covered trims require the 17-inch size, so confirming the exact version avoids choosing the right tire series in the wrong size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Fiat 124 Spider?
Start with the correct primary size for the sub-model: 195/50R16 for Classica or 205/45R17 for Abarth, Lusso, and Urbana. From there, compare construction, sidewall appearance, tire series, and wheel compatibility details such as rim diameter and, where applicable, approved rim-width range.
The 17-inch fitment leans toward blackwall BFGoodrich g-Force options, while the 16-inch fitment adds a very different look through a wide whitewall Silvertown Radial. Intended use matters too, because a car built around visual presentation may call for a different choice than one driven regularly on modern roads.
What sidewall styles are available for 2020 Fiat 124 Spider tires?
Two sidewall styles appear across the available 2020 Fiat 124 Spider tire choices: Blackwall and Wide Whitewall. The 205/45R17 options are blackwall BFGoodrich g-Force tires, while the 195/50R16 option is a BFGoodrich Silvertown Radial with a 2-inch wide whitewall.
That makes sidewall style part of the buying decision, especially if the goal is to shape the car's visual character rather than simply replace worn tires. Appearance should still come after correct size and wheel diameter, since the most attractive sidewall treatment is only useful if it matches the proper fitment for the sub-model.
What tire series are available for the 2020 Fiat 124 Spider?
Available series for the 2020 Fiat 124 Spider include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial. The g-Force lines appear in 205/45R17, while the Silvertown Radial is the available 195/50R16 offering.
Those series give the buyer different ways to approach the same car, depending on sub-model and desired presentation. The 17-inch options center on modern blackwall g-Force styling, while the 16-inch Silvertown choice creates a much more distinctive look, so series selection should follow the correct size rather than replace it.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Fiat 124 Spider?
A period-style choice for a 2020 Fiat 124 Spider starts with the correct sub-model size, then moves to the visual character of the tire. The Classica's 195/50R16 option is available as a BFGoodrich Silvertown Radial with a 2-inch wide whitewall, while the 17-inch trims use blackwall BFGoodrich g-Force series tires.
That means the most suitable appearance depends on whether the goal is a more traditional visual statement or a modern sport-oriented look. Buyers chasing exact originality should compare any sidewall choice against vehicle-specific photos, sales literature, or marque references rather than assuming every tire sold in the right size matches factory delivery.
How does tire construction affect the appearance of a restored 2020 Fiat 124 Spider?
On the 2020 Fiat 124 Spider, the primary fitments are radial, so the visual difference comes less from bias-ply versus radial construction and more from sidewall treatment, profile, and wheel size. A blackwall 205/45R17 gives a low-profile modern look, while the 195/50R16 wide whitewall creates a more stylized presentation.
Appearance also changes with the wheel package under the car. A restored or carefully detailed 124 Spider will look different on the 16-inch setup than on the 17-inch arrangement, so matching the tire to the correct sub-model and wheel diameter is just as important as choosing the sidewall style itself.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Fiat 124 Spider?
Yes. Wheel changes, suspension modifications, or body and alignment changes can affect tire fitment on a 2020 Fiat 124 Spider even when the tire size looks close to the original specification. This matters because the car uses both 16-inch and 17-inch fitments depending on sub-model.
A modified car should be checked for wheel diameter, wheel width, and clearance at the fender, suspension, and steering range before new tires are installed. Lowered ride height or aftermarket wheels can change the space available, so the current setup on the car matters more than assumptions based on model name alone.
What should I inspect before driving a 2020 Fiat 124 Spider on new tires?
Before driving a 2020 Fiat 124 Spider on new tires, inspect tire pressure, valve stems, wheel condition, and lug hardware, then confirm that the tire size matches the sub-model's wheel diameter. It also helps to look for any obvious rubbing marks, uneven wear patterns, or alignment issues carried over from the previous tires.
A short, careful road test is worthwhile after installation. Pay attention to steering response, vibration, and clearance during turns, because those checks can reveal wheel-balance problems or setup issues quickly, especially on a lightweight roadster where tire and wheel changes are easy to feel from the driver's seat.
How often should tires on a 2020 Fiat 124 Spider be inspected?
Tires on a 2020 Fiat 124 Spider should be inspected regularly, not only when tread appears low. Pressure, tread wear, sidewall condition, and signs of impact damage are worth checking often, particularly on a car that may alternate between long storage periods and occasional spirited driving.
Regular inspection matters because low-profile fitments like 205/45R17 can make wheel and sidewall condition especially important, while any lightly used collector-type car can age its tires before wearing them out. Looking the car over before longer drives and after seasonal storage helps catch cracking, air loss, or damage early.
