The 1983 Ferrari 308 GTB sits in the final Quattrovalvole era of Ferrari’s wedge-shaped V8 berlinetta, a period when the model had matured into a more developed road car without losing its distinctly Italian sports-car character. Tire fitment is part of that balance, because this car uses a staggered radial setup with 205/55R16 up front and 225/50R16 at the rear on 16-inch rims. That means the main decision is less about finding a single size and more about matching the front and rear correctly while choosing among blackwall performance-oriented tires or a more appearance-driven whitewall option in front. For a car valued for both handling feel and presentation, size accuracy and wheel compatibility matter first.
Which Tire Size Is Right for The 1983 Ferrari 308 GTB
The 1983 Ferrari 308 GTB uses two primary tire sizes, both in radial construction on 16-inch rims. The key step is identifying where each size belongs, because 205/55R16 is used at the front and 225/50R16 at the rear on the Quattrovalvole 4V setup. Once that staggered layout is confirmed, the decision shifts to tire series, brand, sidewall treatment, and whether the car remains on its original-style wheel arrangement.
205/55R16 is a metric radial size in which 205 identifies the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 16 is the rim diameter in inches. On the 1983 Ferrari 308 GTB, this size is used at the front, where maintaining the proper front-to-rear pairing matters to the car’s overall setup. Available choices include BFGoodrich, Michelin, and American Classic offerings, with blackwall sport-oriented options as well as a wide whitewall variation. This is the size to evaluate when refreshing front-end fitment while preserving the intended staggered tire arrangement.
225/50R16 is also a metric radial size, with 225 indicating nominal section width in millimeters, 50 describing the sidewall profile relative to width, and 16 identifying the wheel diameter. On the 1983 Ferrari 308 GTB, this size belongs at the rear, making it the wider half of the car’s staggered fitment. Products in this size include BFGoodrich and Michelin blackwall radials across sport-focused series such as g-Force and Pilot Sport. This size deserves close attention when replacing rear tires, especially on a car where wheel specification and matching front-to-rear proportions affect both appearance and chassis balance.
Sub-model fitment on the 1983 Ferrari 308 GTB is straightforward in one sense and important in another: the covered Quattrovalvole 4V setup uses a dedicated front and rear size rather than one tire size at all four corners. Checking the exact front or rear position matters before choosing a tire.

1983 Ferrari 308 GTB Quattrovalvole 4V Front
The Quattrovalvole 4V Front uses the narrower front tire in radial construction on a 16-inch rim. That makes front tire selection a matter of keeping the proper staggered relationship while comparing available brands, series, and sidewall treatments in the correct size.
The Quattrovalvole 4V Rear uses the wider rear tire in radial construction on a 16-inch rim. Rear tire choice should stay focused on the correct size first, then on wheel compatibility and the available blackwall performance-oriented product options within that rear fitment.
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 GTB?
The 1983 Ferrari 308 GTB uses a staggered radial tire setup rather than one size at all four corners. The front fitment is 205/55R16, and the rear fitment is 225/50R16, both on 16-inch rims in the Quattrovalvole 4V application.
That means the first step is confirming whether the tire being replaced is on the front or rear of the car. Using the correct front-to-rear pairing matters more than simply matching rim diameter, especially on a sports car where tire width and profile are part of the overall setup.
What size rim does a 1983 Ferrari 308 GTB use?
The 1983 Ferrari 308 GTB uses 16-inch rims with both of its primary tire sizes. The 205/55R16 front tire and the 225/50R16 rear tire are both built for a 16-inch wheel diameter, even though the widths and profiles differ between the two positions.
Rim diameter is only one part of the fitment picture, so it helps to check wheel width as well before choosing a replacement tire. A car that has been changed to aftermarket wheels or a different offset may still have 16-inch rims but require closer review for clearance and proper tire seating.
Which tire size should I use for my 1983 Ferrari 308 GTB sub-model?
The Quattrovalvole 4V front position uses 205/55R16, while the Quattrovalvole 4V rear position uses 225/50R16. This is a position-specific fitment, so the sub-model distinction is really about front versus rear rather than multiple trim levels sharing one common tire size.
A careful replacement starts by checking the wheel location and keeping the staggered arrangement intact unless the car has been deliberately reconfigured. It is also smart to compare the tire currently on the car with the wheel itself, since collector cars are sometimes fitted with non-original wheel packages over time.
Choosing the Right Tire
What should I consider when choosing a 1983 Ferrari 308 GTB tire?
Start with the correct position-specific size, because the 1983 Ferrari 308 GTB uses 205/55R16 in front and 225/50R16 in back. From there, compare radial construction details such as brand, tire series, sidewall style, and the wheel-width range the tire is intended to work with.
The best choice depends on how the car is used and presented. A driver-focused car may lead you toward the available blackwall performance series, while an appearance-driven build may place more value on sidewall style. Either way, keeping the front and rear fitments properly matched should remain the priority.
What sidewall styles are available for 1983 Ferrari 308 GTB tires?
Blackwall is the main sidewall style available for the 1983 Ferrari 308 GTB’s tire sizes, and it appears across both front and rear fitments. A wide whitewall option is also available in the 205/55R16 front size, creating a more specialized appearance choice at the front of the car.
Sidewall style affects presentation more than fitment, but it still needs to be chosen within the correct tire size for each axle. On a 308 GTB, many owners will want the visual balance of the car to remain intentional, so it helps to think through how the front sidewall treatment works with the rear blackwall setup.
What brands offer tires for the 1983 Ferrari 308 GTB?
BFGoodrich, Michelin, and American Classic offer tires in the sizes used on the 1983 Ferrari 308 GTB. BFGoodrich and Michelin appear in both the front and rear fitments, while American Classic is represented in the 205/55R16 front size with a wide whitewall radial.
Brand selection should be weighed alongside size, wheel compatibility, and the type of presentation you want from the car. Looking at the tire series attached to each brand can also help separate performance-oriented blackwall options from appearance-led alternatives, especially when matching a front and rear set.
Restoration & Appearance
Which tire should I choose for a period-style 1983 Ferrari 308 GTB?
A period-style 1983 Ferrari 308 GTB tire choice begins with the proper staggered sizes: 205/55R16 in front and 225/50R16 in the rear. From there, the closest visual direction usually comes from blackwall radial tires, since that presentation aligns naturally with the car’s early-1980s sports-car character.
Appearance goals should stay secondary to correct size and wheel compatibility, especially on a car with a defined front-to-rear setup. When exact originality matters, it is wise to compare your car against marque references or restoration records before settling on a particular brand or sidewall treatment.
How does tire construction affect the appearance of a restored 1983 Ferrari 308 GTB?
On the 1983 Ferrari 308 GTB, construction is straightforward because the primary fitment is radial rather than bias-ply. That means the appearance difference comes less from changing construction type and more from the tire series and sidewall treatment chosen within the correct front and rear radial sizes.
A blackwall radial usually gives the car a more natural sporting presentation, while a wide whitewall front option creates a more stylized look. For a restoration-oriented car, the visual goal should be considered together with the staggered fitment so the finished stance does not look mismatched from front to rear.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1983 Ferrari 308 GTB?
Yes, modifications can affect tire fitment on a 1983 Ferrari 308 GTB even when the tire sizes remain 205/55R16 front and 225/50R16 rear. Aftermarket wheels, different offsets, suspension changes, ride-height alterations, or body modifications can all change how much room the tire has in motion and at full steering lock.
A changed car should be checked at the wheel, not just at the tire sidewall. Confirm wheel diameter and width first, then inspect for clearance around the fenders, suspension, and steering components. That extra step matters on a staggered setup, where front and rear fitment conditions are not identical.
What should I inspect before driving a 1983 Ferrari 308 GTB on new tires?
Before driving a 1983 Ferrari 308 GTB on new tires, inspect the wheels for correct diameter and condition, verify that the front and rear sizes are mounted in the proper positions, and check inflation, valve stems, and basic clearance. It also helps to look over suspension and steering components on a low-use collector car.
A careful road check should include watching for rubbing, unusual vibration, or any sign that the car is reacting differently than expected. Even with the right tire sizes, alignment condition, aged bushings, or prior wheel changes can affect how the car settles on a fresh set of tires.
How should tires on a collector 1983 Ferrari 308 GTB be maintained?
Tires on a collector 1983 Ferrari 308 GTB should be inspected regularly for cracking, cuts, bulges, uneven wear, and air loss, even if the car is driven infrequently. Maintaining proper inflation and keeping the correct 205/55R16 front and 225/50R16 rear positions intact are basic but important parts of long-term care.
Storage conditions matter on collector vehicles because long idle periods can age tires without adding many miles. Clean, dry storage away from prolonged sunlight, heat, and ozone sources helps preserve them, and occasional condition checks are worthwhile before any longer outing after the car has been parked.
