The 1990 Alfa Romeo Spider carried one of the longest-running and most recognizable Italian roadster shapes into the modern era, blending open-top character with a distinctly European tire-and-wheel stance. Buyers looking at this exact car usually reach the tire decision quickly, because fitment depends on sub-model and wheel diameter rather than broad guesswork. The 1990 Alfa Romeo Spider uses radial tires only, with 185/70R14 on Graduate and Veloce models and 195/60R15 on the Quadrifoglio. That opens up meaningful choice in blackwall, wide whitewall, redline, and raised white letter styles across several classic and modern radial series. The right selection comes down to matching the exact sub-model, preserving the look you want, and confirming the wheel setup already on the car.
Which Tire Size Is Right for The 1990 Alfa Romeo Spider
Two primary tire sizes apply to the 1990 Alfa Romeo Spider, and the correct one depends on the specific sub-model and wheel diameter. Graduate and Veloce models use a 14-inch radial fitment, while the Quadrifoglio uses a 15-inch radial fitment. Before choosing a tire, the first step is confirming both the sub-model and the actual wheel diameter currently on the car, especially if wheels have ever been changed.
185/70R14 is a metric radial size in which 185 designates nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 14 is the wheel diameter in inches. On the 1990 Alfa Romeo Spider, this size belongs to the 14-inch-wheel fitment used on certain sub-models. Available choices include blackwall sport-touring and classic-style radials, along with a wide whitewall option, from brands such as BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. This size is the right place to focus if the car retains its 14-inch setup and the goal is either traditional presentation or a more modern road-use character.
195/60R15 is also a metric radial size, with a 195-millimeter nominal section width, a 60-series profile, radial construction, and a 15-inch rim diameter. For the 1990 Alfa Romeo Spider, this size is tied to the 15-inch-wheel fitment rather than the 14-inch setup used elsewhere in the model line. Product choices include blackwall, wide whitewall, redline, and raised white letter styles, primarily from BFGoodrich and Michelin across different radial series. This is the size to evaluate when the car is a Quadrifoglio or when a 15-inch wheel package is already confirmed on the vehicle.
Sub-model fitment matters on the 1990 Alfa Romeo Spider because tire size changes with the wheel package. Graduate and Veloce models share one radial size, while the Quadrifoglio uses a different radial size on a different rim diameter, so identifying the exact version prevents an avoidable mismatch.

1990 Alfa Romeo Spider Graduate
The 1990 Alfa Romeo Spider Graduate uses the 185/70R14 radial fitment. Tire selection here centers on choosing the look and driving character you want within that 14-inch size, while also confirming that the car still carries its intended wheel diameter.
The 1990 Alfa Romeo Spider Quadrifoglio uses the 195/60R15 radial fitment on a 15-inch wheel. That makes wheel confirmation especially important, and it also gives access to several sidewall treatments for owners balancing period-style appearance with road-use preferences.
The 1990 Alfa Romeo Spider Veloce shares the 185/70R14 radial fitment with the Graduate. Once that 14-inch setup is confirmed, the decision shifts from size to choosing among blackwall and classic-style options that suit the car's appearance and intended use.
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.

Common 1990 Alfa Romeo Spider tire questions usually center on the two sub-model-specific sizes, 14-inch versus 15-inch wheel fitment, available radial styles, and how to choose a tire that suits both the car's appearance and real road use.
Tire Size & Fitment
What tire size fits a 1990 Alfa Romeo Spider?
A 1990 Alfa Romeo Spider uses one of two radial tire sizes: 185/70R14 or 195/60R15. The 185/70R14 size applies to the Graduate and Veloce, while the Quadrifoglio uses 195/60R15.
The important step is matching the tire to the exact sub-model and wheel diameter already on the car. Because the two sizes use different rims, selection should start with verifying whether the Spider has 14-inch or 15-inch wheels, especially if a previous owner changed wheels or suspension components.
What size rim does a 1990 Alfa Romeo Spider use?
The 1990 Alfa Romeo Spider uses either a 14-inch or 15-inch rim, depending on sub-model. Graduate and Veloce models use the 14-inch fitment with 185/70R14 tires, while the Quadrifoglio uses a 15-inch fitment with 195/60R15 tires.
Rim diameter should be confirmed before shopping because neither tire size crosses over to the other wheel diameter. It also helps to check wheel width when comparing products, since some tires in these sizes are designed around slightly different approved rim-width ranges than others.
Do all 1990 Alfa Romeo Spider sub-models use the same tire size?
No. The 1990 Alfa Romeo Spider line splits between two sizes. Graduate and Veloce models share 185/70R14 radial tires, while the Quadrifoglio uses 195/60R15 radial tires.
That difference means the sub-model is not just a trim detail when choosing tires. It determines both the tire size and the wheel diameter, so the safest approach is to confirm the badge, inspect the current wheel setup, and then compare tires only within the correct size group for that version.
Choosing the Right Tire
What should I consider when choosing a 1990 Alfa Romeo Spider tire?
Start with the correct size for the car's sub-model: 185/70R14 for Graduate and Veloce, or 195/60R15 for Quadrifoglio. From there, compare radial construction details such as sidewall style, tire series, rim-width compatibility, and whether the tire's overall look suits a classic Italian roadster.
A Spider used mainly for shows or weekend cruising may call for a different presentation than one driven more regularly. It helps to look at wheel width, load figures where shown, and the visual character of blackwall, whitewall, redline, or raised white letter options before narrowing the field.
What sidewall styles are available for 1990 Alfa Romeo Spider tires?
Sidewall choices for the 1990 Alfa Romeo Spider include blackwall, wide whitewall, redline, and raised white letter styles, depending on tire size. The broader variety appears in 195/60R15, while 185/70R14 includes blackwall options along with a wide whitewall selection.
That makes sidewall style an appearance decision as much as a fitment decision. A blackwall usually keeps the look more understated and European, while whitewall, redline, or raised white letter treatments create a more stylized presentation, so the right choice depends on how the car is restored, displayed, and driven.
What brands offer tires for the 1990 Alfa Romeo Spider?
Tires for the 1990 Alfa Romeo Spider are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, depending on the size. The 185/70R14 fitment has the widest brand spread, while 195/60R15 includes BFGoodrich and Michelin offerings.
Brand is only one part of the selection process. It is still important to compare the correct size, the tire series, approved rim-width range when shown, and the sidewall treatment, because two tires from different brands may suit very different goals in appearance and road use.
Restoration & Appearance
Which tire should I choose for a period-style 1990 Alfa Romeo Spider?
A period-style 1990 Alfa Romeo Spider tire starts with using the correct sub-model size: 185/70R14 for Graduate and Veloce or 195/60R15 for Quadrifoglio. From there, the most appropriate choice depends on whether the goal is a restrained blackwall look or a more distinctive presentation such as wide whitewall or redline.
Because appearance preferences vary widely on late classic European cars, tire choice should support the way the Spider is being restored rather than follow a one-style-fits-all rule. Owners pursuing exact originality should compare the chosen sidewall treatment with marque-specific photography, literature, or club guidance before finalizing the set.
How does tire construction affect the appearance of a restored 1990 Alfa Romeo Spider?
Tire construction is straightforward on the 1990 Alfa Romeo Spider because both primary fitments are radial. That means the visual difference usually comes less from bias-ply versus radial and more from the tire's series, profile, and sidewall treatment within the correct radial size.
A restored Spider can look noticeably different depending on whether it wears blackwalls, wide whitewalls, redlines, or raised white letters. Keeping the correct size and wheel diameter in place helps preserve the car's stance, while the sidewall design shapes whether the final presentation feels understated, sporty, or more custom.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1990 Alfa Romeo Spider?
Yes. Wheel changes, altered wheel width, different offsets, suspension lowering, and body modifications can all affect tire fitment on a 1990 Alfa Romeo Spider. That matters even more here because the car already uses two different wheel diameters across its sub-model range.
A Spider with aftermarket wheels should be checked for actual rim diameter, width, and clearance at the fenders and steering components before any tire is chosen. Comparing only the factory size without verifying the current setup can lead to a mismatch in appearance, wheel compatibility, or running clearance.
What should I inspect before driving a 1990 Alfa Romeo Spider on new tires?
Before road use, inspect the wheel condition, confirm the correct tire pressure for the installed tires, and make sure each tire is mounted on the proper rim diameter. It is also wise to check for suspension wear, uneven ride height, and any signs that the car has been modified.
Collector cars often spend long periods parked, so a short visual check is not enough. Look for rubbing marks, verify lug hardware condition, and recheck clearances lock-to-lock after installation, especially on a Spider that may have changed wheels at some point in its life.
How should tires on a collector 1990 Alfa Romeo Spider be maintained?
Tires on a collector 1990 Alfa Romeo Spider should be kept properly inflated, inspected regularly for cracking, cuts, bulges, uneven wear, and slow air loss, and protected from long exposure to sun, moisture, and ozone sources. Regular movement or careful storage helps prevent flat spotting during long idle periods.
Maintenance also means checking the tires in context of the whole car. Alignment issues, tired suspension parts, or wheels that are not true can shorten tire life and affect how the Spider feels on the road, so periodic inspection should include both the tires and the chassis around them.
