The 1986 Alfa Romeo Spider belongs to the later Series 4 era, when the long-running Italian roadster blended classic open-top character with more modern road manners and trim distinctions. Buyers looking at one today are often balancing originality, drivability, and the visual style that best suits the car’s personality. Tire fitment for the 1986 Alfa Romeo Spider centers on three radial sizes tied to specific sub-models: 185/70R14, 195/70R14, and 195/60R15. That opens the door to different looks, including blackwall, wide whitewall, redline, and raised white letter options in certain sizes. The key is matching the exact sub-model and wheel diameter before choosing a tire style.
Which Tire Size Is Right for The 1986 Alfa Romeo Spider
The 1986 Alfa Romeo Spider uses three different tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Two sizes fit 14-inch rims and one fits a 15-inch rim, so the first step is confirming whether the car is a Graduate, Veloce, or Quadrifoglio and verifying the wheels currently on the car before comparing tire styles and product choices.
185/70R14 is a metric radial size: 185 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1986 Alfa Romeo Spider, this size is used on a 14-inch wheel and suits buyers staying with the Graduate fitment. Available choices include blackwall and wide whitewall options from brands such as BFGoodrich, Avon, Dunlop, Michelin, and Vredestein across series like Silvertown Radial, CR6ZZ, Sport Classic, Michelin XAS, and Sprint Classic. It is the size to evaluate when maintaining the Graduate’s intended wheel setup while choosing between traditional and more performance-oriented presentations.
195/60R15 is a metric radial size in which 195 represents nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 15 identifies the rim diameter. For the 1986 Alfa Romeo Spider, this size belongs with the 15-inch-wheel Quadrifoglio configuration rather than the 14-inch cars. Product choices include blackwall, wide whitewall, redline, and raised white letter sidewalls, with BFGoodrich and Michelin offerings spread across Silvertown Radial, Radial T/A, and Michelin Primacy 3 lines. This size deserves close attention when appearance is part of the decision, since it offers the broadest visible sidewall variety of the three fitments.
195/70R14 follows the same metric radial format: 195 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches. On the 1986 Alfa Romeo Spider, this size is tied to a 14-inch wheel and matches the Veloce fitment. The available choice here is a blackwall Dunlop Sport Classic, which keeps the selection focused on maintaining the proper size rather than sorting through multiple visual treatments. It is the size to confirm when the car is a Veloce or when a 14-inch Spider needs the wider and taller-looking of the two 14-inch fitments.
Sub-model fitment matters on the 1986 Alfa Romeo Spider because the Graduate, Veloce, and Quadrifoglio do not all use the same tire size. Confirming the exact sub-model and the wheel diameter on the car is the most important step before comparing sidewall style, brand, or tire series.

1986 Alfa Romeo Spider Graduate
The 1986 Alfa Romeo Spider Graduate uses the 185/70R14 radial size on a 14-inch rim. That makes tire choice more about selecting the right blackwall or whitewall presentation and matching the tire to the car’s intended road use while keeping the Graduate wheel setup intact.
The 1986 Alfa Romeo Spider Quadrifoglio uses 195/60R15 radial tires on a 15-inch wheel. This fitment brings the widest appearance range of the three sub-models, so the decision often comes down to confirming the 15-inch wheels first and then choosing among blackwall, redline, wide whitewall, or raised white letter options.
The 1986 Alfa Romeo Spider Veloce uses the 195/70R14 radial size on a 14-inch rim. Tire selection is straightforward here, with the main priority being correct size and wheel confirmation rather than sorting through many alternate sidewall treatments or series.
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 questions for the 1986 Alfa Romeo Spider usually come down to sub-model-specific tire size, 14-inch versus 15-inch wheel fitment, sidewall style choices, and what to inspect before putting a collector-era roadster back on the road.
Tire Size & Fitment
What tire size fits a 1986 Alfa Romeo Spider?
The 1986 Alfa Romeo Spider uses three different radial tire sizes depending on sub-model: 185/70R14, 195/70R14, and 195/60R15. The Graduate uses 185/70R14, the Veloce uses 195/70R14, and the Quadrifoglio uses 195/60R15.
That means the first job is identifying the exact sub-model and checking the wheel diameter currently on the car. A 14-inch Spider and a 15-inch Spider do not use the same tire, and a car that has been changed over to different wheels should be verified before choosing by appearance or brand.
What size rim does a 1986 Alfa Romeo Spider use?
A 1986 Alfa Romeo Spider uses either a 14-inch or 15-inch rim, depending on the sub-model. The Graduate and Veloce use 14-inch tire fitments, while the Quadrifoglio uses a 15-inch tire fitment.
Wheel diameter should be confirmed before anything else because the tire sizes are not interchangeable across those rim diameters. It is also worth checking the actual wheels on the car, since many older Spiders have seen wheel changes over the years that can alter what size should be considered.
Do all 1986 Alfa Romeo Spider sub-models use the same tire size?
No, the 1986 Alfa Romeo Spider sub-models do not all use the same tire size. The Graduate uses 185/70R14, the Veloce uses 195/70R14, and the Quadrifoglio uses 195/60R15.
That variation affects more than the numbers on the sidewall. It changes the wheel diameter involved and also affects which product styles are available, especially on the Quadrifoglio, where whitewall, redline, blackwall, and raised white letter options are all part of the decision once the correct fitment is confirmed.
Choosing the Right Tire
What should I consider when choosing a tire for a 1986 Alfa Romeo Spider?
Start with the exact sub-model and correct size, because a 1986 Alfa Romeo Spider does not use one universal fitment. Graduate, Veloce, and Quadrifoglio models use different radial sizes, and the Quadrifoglio also changes the wheel diameter to 15 inches.
After size is settled, compare the tire’s sidewall style, series, rim-width compatibility, and overall presentation. A blackwall performance-style radial gives a different look than a wide whitewall or redline, so the right choice depends on whether the goal is road use, a restoration-oriented appearance, or a blend of both.
What sidewall styles are available for 1986 Alfa Romeo Spider tires?
Sidewall style depends on the tire size used by the sub-model. Across the 1986 Alfa Romeo Spider fitments, available styles include blackwall, wide whitewall, redline, and RWL, which is raised white letter.
The broadest style range appears in 195/60R15 for the Quadrifoglio, while the 14-inch sizes are more heavily centered on blackwall, with one wide whitewall option in 185/70R14. Choosing among them is mainly an appearance decision once the correct size and wheel diameter have already been verified.
What brands offer tires for the 1986 Alfa Romeo Spider?
Tires for the 1986 Alfa Romeo Spider are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein, depending on size. Brand availability changes with the fitment, so one sub-model may have several choices while another has a much narrower selection.
That makes it useful to compare brand offerings only after the correct size is confirmed. A Graduate owner can sort through several 185/70R14 options, while a Veloce owner with 195/70R14 has a more focused path, and a Quadrifoglio owner can weigh both brand and sidewall style within 195/60R15.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Alfa Romeo Spider?
A period-style choice for a 1986 Alfa Romeo Spider starts with the correct sub-model size, then moves to the visual character of the tire itself. Blackwall tires generally preserve a more restrained European sports-car look, while certain sizes also open the door to whitewall or redline styling.
For a restoration-oriented car, the goal is usually to keep the right proportions and wheel diameter first, then select the sidewall treatment that matches the era and personality you want the car to project. Exact originality questions are best checked against model-specific reference material, photos, or marque-club guidance.
How does tire construction affect the appearance of a restored 1986 Alfa Romeo Spider?
On the 1986 Alfa Romeo Spider, construction is straightforward because the primary fitments are radial tires. That means the appearance differences are less about choosing between bias-ply and radial and more about selecting the proper metric size, sidewall treatment, and tire series for the sub-model.
A restored Spider can look notably different with blackwalls versus wide whitewalls, redlines, or raised white letters, especially on the 195/60R15 Quadrifoglio fitment. Keeping the correct wheel diameter and tire proportions matters more than chasing novelty, since those basics shape the car’s stance and presentation most visibly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Alfa Romeo Spider?
Yes, modifications can affect tire fitment on a 1986 Alfa Romeo Spider. Wheel swaps, suspension changes, altered ride height, or body modifications can all change the space available for the tire, even when the car originally used one of the standard 185/70R14, 195/70R14, or 195/60R15 sizes.
Older Spiders are often changed over time, so it is smart to inspect the actual wheel diameter and width already on the car before selecting tires. Steering clearance, fender clearance, and the relationship between tire and suspension components are worth checking carefully, especially when moving away from a known stock-style setup.
What should I inspect before driving a 1986 Alfa Romeo Spider on new tires?
Before road use, inspect the wheel condition, confirm the wheel diameter matches the chosen tire size, and check that the tires are seated properly and inflated to an appropriate pressure for the application. It is also wise to look over valve stems, lug hardware, tread condition, and any signs of uneven suspension-related wear.
A collector-era roadster should also be checked for clearance at full steering lock and through normal suspension movement. Fresh tires cannot compensate for worn steering parts, weak shocks, or alignment issues, so a brief mechanical inspection helps the Spider drive as intended and protects the new tires from premature problems.
How should tires on a collector 1986 Alfa Romeo Spider be maintained?
Tires on a collector 1986 Alfa Romeo Spider should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and air loss, and protected from long idle periods on underinflated tires. Tread depth matters, but age and storage condition are just as important on a car that may not be driven often.
Storage habits have a real effect on tire life, so keeping the Spider away from prolonged heat, direct sunlight, moisture, and ozone sources is worthwhile. Regular movement, pressure checks, and occasional close inspection of both sidewalls can help catch problems early before a weekend drive turns into a roadside issue.
