The 1984 Ferrari 308 GTB sits in the final Quattrovalvole phase of Ferrari’s V8 berlinetta development, a period when the 308 had matured into a sharper, more modern road car without losing its unmistakable mid-engine character. Tire fitment on this car reflects that evolution, using a staggered radial setup with 205/55R16 in front and 225/50R16 in the rear on 16-inch wheels. That makes the key decision less about broad sizing and more about selecting the right front-to-rear pairing, tire series, and appearance. Blackwall sport radials dominate the choices, while a wide whitewall option adds a very different visual direction. Wheel width, intended use, and preservation goals should guide the final choice.
Which Tire Size Is Right for The 1984 Ferrari 308 GTB
The 1984 Ferrari 308 GTB uses two primary tire sizes, both in metric radial construction on 16-inch wheels. Fitment is staggered rather than interchangeable, so the first step is confirming whether you are selecting a front or rear tire for the Quattrovalvole 4V setup. Once that is established, the decision becomes choosing among available brands, tire series, and sidewall treatments within the correct position-specific size.
In 205/55R16, the 205 designates nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 1984 Ferrari 308 GTB, this size serves the front position and supports the car’s later-model staggered layout. Available choices include BFGoodrich, Michelin, and American Classic, with blackwall sport-oriented offerings and one wide whitewall radial for a very different appearance. The right pick depends on whether the goal is a modern performance presentation, a brand-specific fitment preference, or a more individualized visual style.
In 225/50R16, the 225 indicates nominal section width in millimeters, 50 is the aspect ratio, R means radial construction, and 16 is the wheel diameter in inches. This is the rear tire size for the 1984 Ferrari 308 GTB Quattrovalvole 4V and is part of the car’s wider rear fitment strategy. Available products come from BFGoodrich and Michelin, all in blackwall form, with tire series that range from sport-focused patterns to more established performance lines. Choosing this size correctly means matching the rear wheel position and confirming wheel width before comparing individual tire characteristics.
Sub-model fitment on the 1984 Ferrari 308 GTB is position-specific rather than trim-variant in the usual sense. The key distinction is front versus rear on the Quattrovalvole 4V setup, so selecting the correct tire starts with identifying which end of the car needs replacement.

1984 Ferrari 308 GTB Quattrovalvole 4V Front
The Quattrovalvole 4V Front uses a 205/55R16 radial tire as part of the 308 GTB’s staggered layout. That makes front tire selection a matter of choosing the correct metric radial size first, then comparing brand, tire series, and sidewall treatment within that front application.
The Quattrovalvole 4V Rear uses a 225/50R16 radial tire, separate from the narrower front fitment. Rear tire choice should stay centered on that specific size, with attention to wheel width compatibility and the tire series best suited to the car’s intended road 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.
Best 1984 Ferrari 308 GTB Tires for Sale
Available 1984 Ferrari 308 GTB tire choices center on 205/55R16 front and 225/50R16 rear radials from BFGoodrich, Michelin, and American Classic. The main points of comparison are blackwall versus wide whitewall appearance, sport-oriented tire series, and rim-width compatibility across the front and rear sizes.
Common 1984 Ferrari 308 GTB tire questions usually come down to the staggered front and rear sizes, 16-inch wheel fitment, available radial choices, appearance differences, and the checks worth making before road use on a collector-era Ferrari.
Tire Size & Fitment
What tire size fits a 1984 Ferrari 308 GTB?
The 1984 Ferrari 308 GTB uses a staggered tire setup: 205/55R16 in the front and 225/50R16 in the rear. Both are radial sizes designed for 16-inch wheels, so the car does not use the same tire size at all four corners.
That front-to-rear split matters when replacing one pair or assembling a full set. A buyer should confirm whether the car still has its intended wheel arrangement, then select the correct size for each axle rather than assuming the front and rear tires are interchangeable.
What size rim does a 1984 Ferrari 308 GTB use?
The 1984 Ferrari 308 GTB uses 16-inch rims with both of its primary tire sizes. The front 205/55R16 and rear 225/50R16 are both built around a 16-inch wheel diameter, even though their widths and profiles differ.
Wheel diameter is only the first check, because width also affects suitability. Front tires in this fitment are matched to narrower rim-width ranges than the rear, so anyone dealing with replacement wheels or modified wheels should confirm both diameter and width before choosing tires.
Why does the 1984 Ferrari 308 GTB have more than one tire size?
The 1984 Ferrari 308 GTB uses two sizes because its Quattrovalvole 4V layout is staggered, with a narrower 205/55R16 front tire and a wider 225/50R16 rear tire. That arrangement reflects a front-and-rear fitment strategy rather than a choice between two interchangeable sizes.
In practical terms, the first question is always tire position. A front tire should be chosen from the 205/55R16 options, while a rear tire should be chosen from the 225/50R16 options, followed by checks for wheel width compatibility, overall condition of the chassis setup, and intended driving use.
Choosing the Right Tire
What should I consider when choosing a 205/55R16 and 225/50R16 tire set for a 1984 Ferrari 308 GTB?
Start with the correct staggered sizes: 205/55R16 for the front and 225/50R16 for the rear. From there, compare radial tire series, brand, sidewall style, and wheel-width compatibility so the set matches both the car’s layout and the way it will be used.
Some owners will want a blackwall sport-oriented look, while others may be drawn to a more unusual visual presentation at the front. It also helps to compare product details such as load figures where stated and to make sure both axles are being matched thoughtfully rather than mixed casually.
What sidewall styles are available for 1984 Ferrari 308 GTB tires?
Most available 1984 Ferrari 308 GTB tire choices are blackwall radials, especially in the sport-oriented BFGoodrich and Michelin offerings. A wide whitewall option is also available in the 205/55R16 front size through the American Classic Radial line.
That means sidewall appearance can change the car’s visual character significantly, particularly if the front tires are being replaced individually. Buyers trying to maintain a consistent presentation should consider whether they want an all-blackwall look or a deliberately customized appearance before selecting by brand or series.
What brands offer tires for the 1984 Ferrari 308 GTB?
Tires for the 1984 Ferrari 308 GTB are available from BFGoodrich, Michelin, and American Classic. BFGoodrich appears in both the front and rear sizes, Michelin also covers both positions, and American Classic is available in the 205/55R16 front size.
Brand choice should be weighed alongside size position, sidewall style, and tire series rather than considered by name alone. Since the car uses different front and rear sizes, it is also worth checking whether the preferred brand is available for both ends before planning a matched set.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Ferrari 308 GTB?
A period-style approach starts by preserving the correct staggered 205/55R16 front and 225/50R16 rear radial fitment. From there, blackwall tires from BFGoodrich or Michelin will usually align more closely with the restrained performance appearance many owners want on a 1980s Ferrari.
A restoration-oriented choice is not just about size, because tread character, sidewall presentation, and the balance between front and rear all shape how the car looks. Anyone chasing exact historical accuracy should compare tire details against marque references and vehicle-specific documentation before settling on one series.
How does tire construction affect the appearance of a restored 1984 Ferrari 308 GTB?
On the 1984 Ferrari 308 GTB, construction is straightforward because the primary fitment is radial front and rear. That keeps the visual decision focused less on bias-ply versus radial and more on sidewall treatment, tread style, and the proportions created by the staggered 16-inch setup.
Appearance can still shift noticeably depending on the tire chosen. A blackwall radial keeps the look more in line with an eighties high-performance presentation, while a wide whitewall front tire creates a much more customized visual effect that may suit personal taste better than restoration-oriented goals.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Ferrari 308 GTB?
Yes, modifications can affect tire fitment on a 1984 Ferrari 308 GTB even when the tire sizes remain 205/55R16 front and 225/50R16 rear. Changes to wheel width, wheel offset, suspension height, springs, or body clearance can alter how those tires sit and move under steering and compression.
A car with aftermarket wheels or suspension work should be checked carefully before new tires are selected. Clearance at the fenders, suspension components, and full steering lock matters just as much as size, especially on a low, tightly packaged sports car with staggered fitment.
What should I inspect before driving a 1984 Ferrari 308 GTB on new tires?
Before driving a 1984 Ferrari 308 GTB on new tires, inspect wheel condition, valve stems, tire pressure, and the basic front-to-rear size placement. It also helps to confirm that the front tires are 205/55R16, the rear tires are 225/50R16, and both are seated on appropriate 16-inch wheels.
A collector car deserves a broader walk-around before road use. Check for rubbing marks, uneven suspension height, looseness in steering components, and any signs of air loss after mounting, then take the car on a short, careful drive to confirm stable behavior before longer use.
What should I check before a longer drive in a 1984 Ferrari 308 GTB?
Before a longer drive, confirm tire pressure, tread condition, sidewall condition, and the absence of bulges, cuts, or slow air loss. On a 1984 Ferrari 308 GTB, it is also wise to make sure the staggered tire sizes have been installed in the correct front and rear positions.
Low-use collector vehicles can look fine in the garage while still carrying aged or compromised tires. A longer trip is a good reason to recheck wheel hardware, inspect for any clearance issues that appear under load, and verify that the tires suit the car’s current wheel and suspension setup.
