The 1983 Ferrari 308 GTS sits in the final Quattrovalvole era of Ferrari’s classic V8 wedge-shaped road cars, a period when styling, balance, and road manners mattered as much as outright speed. For many owners, the appeal is preserving that unmistakable mid-engine character while keeping the car usable on modern roads. Tire fitment centers on a staggered radial setup, with 205/55R16 at the front and 225/50R16 at the rear on 16-inch rims. That gives the car a clear front-to-rear sizing strategy, along with choices in brand and tire series. The real task is matching the right front and rear sizes to the car’s wheel setup, appearance goals, and intended driving use.
Which Tire Size Is Right for The 1983 Ferrari 308 GTS
The 1983 Ferrari 308 GTS uses two primary tire sizes, both in radial construction on 16-inch rims. The key fitment step is identifying the position on the car, since the front uses 205/55R16 and the rear uses 225/50R16. Once that staggered layout is confirmed, the decision shifts to choosing among available tire series, brand options, and sidewall presentation within the correct size.
A 205/55R16 tire uses a 205-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 1983 Ferrari 308 GTS, this is the front tire size and it plays an important role in preserving the car’s intended staggered setup. Available choices include BFGoodrich, Michelin, and American Classic offerings, with blackwall and wide whitewall sidewall styles represented across several tire series. This size should be chosen when the front wheel position and wheel dimensions match the original 16-inch front arrangement.
A 225/50R16 tire carries a wider 225-millimeter section width, a 50-series profile, radial construction, and a 16-inch rim diameter. On the 1983 Ferrari 308 GTS, this size is used at the rear, giving the car the broader rear footprint associated with its staggered fitment. BFGoodrich and Michelin options are available in this size, all with blackwall sidewalls and multiple performance-oriented tire series. This is the size to evaluate when replacing rear tires and confirming that the rear wheel width remains consistent with the car’s intended setup.
Fitment on the 1983 Ferrari 308 GTS is position-specific rather than uniform from front to rear. Checking whether the tire is for the front or rear matters first, because each covered Quattrovalvole 4V position uses its own size within the staggered 16-inch setup.

1983 Ferrari 308 GTS Quattrovalvole 4V Front
The Quattrovalvole 4V Front uses the 205/55R16 radial size on a 16-inch rim. That makes front tire selection less about alternate sizing and more about choosing the right series, brand, and sidewall treatment while keeping the staggered front-to-rear relationship intact.
The Quattrovalvole 4V Rear uses the wider 225/50R16 radial size on a 16-inch rim. Rear replacement should focus on maintaining the correct position-specific size and confirming wheel width and clearance before selecting among the available performance-oriented radial options.
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.

Tire Size & Fitment
What tire size fits a 1983 Ferrari 308 GTS?
The 1983 Ferrari 308 GTS uses a staggered tire setup rather than one uniform size at all four corners. The front size is 205/55R16 and the rear size is 225/50R16, and both are radial tires built for 16-inch rims.
That means the first step is confirming whether the tire being replaced is on the front or rear of the car. Using the correct position-specific size helps preserve the intended front-to-rear balance, so the wheel location, actual rim width, and any prior wheel changes should be checked before selecting a replacement.
What size rim does a 1983 Ferrari 308 GTS use?
The 1983 Ferrari 308 GTS uses 16-inch rim diameter tires at both the front and rear. The front 205/55R16 and rear 225/50R16 sizes share that same 16-inch diameter, even though the rear tire is wider and slightly lower in profile.
Matching the 16-inch diameter is only part of the fitment picture. Tire selection should also account for the actual wheel width on the car, since available 205/55R16 and 225/50R16 tires have different rim-width ranges, and altered wheels can change how well a replacement tire suits the vehicle.
Why does the 1983 Ferrari 308 GTS have more than one tire size?
The 1983 Ferrari 308 GTS uses different tire sizes because it has a staggered front-and-rear setup. The 205/55R16 front tire and 225/50R16 rear tire work together as a position-specific arrangement rather than as interchangeable sizes.
That staggered layout means tire choice depends on where the tire will be installed, not just the year and model name. It is worth checking both wheel position and wheel dimensions before replacement, especially if the car has had aftermarket wheels fitted or if the current tires were installed by a previous owner.
Choosing the Right Tire
What should I consider when choosing a 205/55R16 and 225/50R16 tire set for a 1983 Ferrari 308 GTS?
Start with the correct staggered sizing: 205/55R16 for the front and 225/50R16 for the rear. From there, compare construction, tire series, rim-width compatibility, sidewall style where offered, and any load information shown for the specific tire being considered.
The right choice depends on how the car will be used and how closely the owner wants to maintain its intended presentation. A driver-focused setup may lean toward modern performance-oriented blackwall radials, while a more appearance-driven approach may place added weight on sidewall style and how the tire looks on the car.
What sidewall styles are available for 1983 Ferrari 308 GTS tires?
Sidewall style depends on tire size and product selection. Blackwall is the main presentation across both 205/55R16 and 225/50R16, while a wide whitewall option appears in the 205/55R16 front size through the American Classic Radial line.
That means sidewall appearance can influence the final tire choice, especially at the front where more visual variety exists. Owners trying to shape a particular look should confirm that the selected sidewall treatment is available in the exact front or rear size needed, rather than assuming the same appearance carries across both positions.
What brands offer tires for the 1983 Ferrari 308 GTS?
The 1983 Ferrari 308 GTS has tire options from BFGoodrich and Michelin in both of its primary sizes. The 205/55R16 front size also includes an American Classic offering, giving that position an added appearance-oriented choice alongside the more conventional blackwall radials.
Brand selection matters most when paired with the exact size, tire series, and visual style that suits the car. Instead of choosing by brand name alone, compare whether the tire is intended for the front or rear, whether its rim-width range matches the wheel, and whether its appearance fits the way the car is being presented.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Ferrari 308 GTS?
A period-style approach starts by preserving the 1983 Ferrari 308 GTS staggered fitment of 205/55R16 front and 225/50R16 rear. Since this car already uses radial construction, the appearance decision usually comes down to tire series and sidewall presentation rather than deciding between vintage bias-ply and radial formats.
Blackwall tires will usually align more closely with the sporting character many owners want, while a wide whitewall front option creates a distinctly different visual statement. Anyone pursuing exact originality should verify brand, sidewall treatment, and presentation details through Ferrari-specific historical references before treating any currently available tire as definitive.
Does correct tire fitment matter for a 1983 Ferrari 308 GTS restoration?
Correct tire fitment matters because the 1983 Ferrari 308 GTS uses different sizes at the front and rear, and that staggered relationship is part of the car’s overall presentation. Using the proper 16-inch radial sizes helps keep the visual stance and intended wheel-to-tire proportion closer to the car’s original character.
Restoration-minded owners should look beyond the size code alone and consider sidewall style, tire series, and how the tire fills the wheel opening. Even on a road-driven car, details such as an overly modern visual profile or a mismatched front-to-rear presentation can change the look of the finished vehicle more than expected.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Ferrari 308 GTS?
Yes. A 1983 Ferrari 308 GTS may no longer have its original wheel and suspension setup, and changes such as aftermarket wheels, altered offsets, suspension lowering, or body modifications can affect how 205/55R16 front and 225/50R16 rear tires sit and clear.
That is why replacement should begin with the actual wheel dimensions on the car rather than the model name alone. Clearance at the fender, inner wheelhouse, and steering range deserves a careful check, especially when the car has been modified or when the outgoing tires differ from the intended staggered sizing.
What should I inspect before driving a 1983 Ferrari 308 GTS on new tires?
Before road use, inspect inflation pressure, wheel fastener tightness, valve stems, tread seating, and visible clearance at both front and rear. It also helps to confirm that the front carries 205/55R16 tires and the rear carries 225/50R16 tires, since the car does not use one uniform size all around.
A short initial drive should be followed by another visual check for rubbing, unusual wear, or pressure loss. Collector cars often spend long periods parked, so it is wise to inspect the rest of the chassis as well, including suspension condition and alignment-related issues that may affect how the new tires wear.
How should 205/55R16 and 225/50R16 tires on a collector 1983 Ferrari 308 GTS be maintained?
Collector-car tire maintenance starts with regular pressure checks, visual inspections, and keeping the staggered front and rear sizes in their proper positions. Even when tread looks healthy, low-use tires should be watched for age-related cracking, flat spotting from storage, bulges, cuts, or slow air loss.
Storage conditions matter almost as much as mileage on an infrequently driven Ferrari. Clean, dry conditions away from prolonged sunlight, heat, and ozone sources help preserve the tires, and periodic movement of the car can reduce set-in flat spots during long storage intervals between drives.
