Ferrari 328 GTB Tires

Ferrari 328 GTB uses two tire sizes across the full 1986 through 1989 production run: 205/55R16 and 225/50R16. Both sizes are radial tires built for 16-inch rims, with the 205/55R16 products fitting rim widths from 5.5 to 7.5 inches and the 225/50R16 products fitting rim widths from 6.0 to 8.0 inches. There is no year-to-year size change within the 328 GTB range shown here.

The practical issue is not model year so much as axle position. Ferrari 328 GTB uses a staggered setup, so you should confirm whether you are replacing the narrower size, the wider size, or both as a matched set. Checking the existing tire sidewall and the wheel width on the car is the cleanest way to avoid ordering two fronts or two rears by mistake.

On Ferrari 328 GTB, 205/55R16 is a metric radial size. The 205 is the section width in millimeters, 55 is the aspect ratio, meaning the sidewall height is 55 percent of the section width, R indicates radial construction, and 16 is the required rim diameter in inches. The available products in this size are all 16-inch radial tires.

That decoding matters because modern performance tires can look similar while differing in width, profile, or wheel diameter. On a Ferrari 328 GTB, using the correct 205/55R16 size preserves the intended relationship between the tire, wheel, and chassis geometry on the narrower end of the staggered setup. Always compare the sidewall marking on the tire already fitted before replacing a single tire.

Ferrari 328 GTB uses 16-inch rims for both listed tire sizes. The 205/55R16 products are built for 16-inch wheels with approved rim widths from 5.5 to 7.5 inches, while the 225/50R16 products are also 16-inch tires but fit wider rims from 6.0 to 8.0 inches. There is no alternate rim diameter shown within the 1986 to 1989 range.

Rim diameter is still worth checking on the car because a collector Ferrari may have had wheel changes over the years. Read the size directly from the current tire sidewall and compare it to the wheel fitted on the car, especially if you are replacing only one axle. Matching the 16-inch diameter is mandatory before you consider tread pattern, brand, or sidewall style.

A 1986 Ferrari 328 GTB uses the same two sizes found throughout the model run: 205/55R16 and 225/50R16. Both are 16-inch radial tires, but they are not interchangeable because they represent the narrower and wider positions in the car's staggered setup. The same guidance applies to 1987, 1988, and 1989 Ferrari 328 GTB models.

Start by reading the sidewall of the tire currently mounted on the axle you are servicing. Then compare that size to the wheel width, since the 205 size suits a narrower wheel range and the 225 size suits a wider one. If the car has been modified, that direct inspection matters more than assuming every wheel on the car still matches its original front and rear arrangement.

Ferrari 328 GTB tire options here include Blackwall and Wide Whitewall sidewall styles. Blackwall appears across both 205/55R16 and 225/50R16 offerings, while the Wide Whitewall option appears in 205/55R16 through the American Classic Radial line. That means the sidewall choice is broader on the narrower size than on the wider size.

For most Ferrari 328 GTB owners seeking a period-appropriate late-1980s appearance, blackwall is the natural visual fit. A wide whitewall is a styling departure and would usually be chosen only for a custom presentation rather than a standard restoration look. If appearance matters as much as size, decide on the visual goal before selecting between available 205/55R16 products.

Ferrari 328 GTB tires in these sizes are available from BFGoodrich, Michelin, and American Classic. BFGoodrich appears in both sizes with multiple g-Force series options, Michelin appears in both sizes with performance-oriented offerings, and American Classic appears in 205/55R16. That gives the 328 GTB buyer a mix of mainstream performance and specialty collector-oriented choices.

Brand choice should follow the kind of use the car actually sees. A frequently driven Ferrari 328 GTB may call for a modern-looking blackwall radial, while a car built more around presentation may lead an owner toward a different visual style in the front-size range. Once the correct size is confirmed, compare construction style, sidewall appearance, and intended use rather than choosing by brand name alone.

Ferrari 328 GTB tire series here include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Michelin SX MXX3 N2, Michelin Pilot Sport, and American Classic Radial. All of them are radial tires, but they differ in branding focus, sidewall presentation, and size coverage. Most are blackwall performance-style radials, while American Classic Radial adds a wide whitewall option in 205/55R16.

Those differences matter most when balancing appearance against use. If your Ferrari 328 GTB is driven in a way that favors a contemporary performance feel, the blackwall radial choices are the obvious starting point. If the car is being styled with a more custom visual treatment, the whitewall option may shape your decision on the narrower size while the wider size remains blackwall-only.

Ferrari 328 GTB should be stored on clean, properly inflated tires in a cool, dry, dark environment away from ozone sources such as electric motors, chargers, and welding equipment. The tires should be kept off oil-soaked concrete and protected from long periods of direct sunlight. A late-classic performance car like the 328 GTB also benefits from being rolled occasionally so the same footprint does not stay loaded for months.

If the car will sit for an extended period, increase your attention to flat-spotting and pressure loss. Tire cradles or periodic movement can help, especially on lower-profile radials like those used on Ferrari 328 GTB. Good storage habits preserve ride quality and sidewall condition, which matters on a collector Ferrari even when tread wear is minimal.

Tires on a Ferrari 328 GTB should be visually inspected before each drive and more carefully at regular intervals during the season. Check inflation pressure, sidewall condition, tread wear pattern, and any signs of cracking, puncture damage, or impact bruising. Because the car uses two different sizes, inspect front and rear tires separately rather than assuming they are wearing at the same rate.

Frequent inspection is especially important on collector cars that alternate between long storage periods and spirited use. A Ferrari 328 GTB can look fine at rest while still developing age-related issues or uneven wear from alignment changes. Catching those problems early helps preserve both handling balance and the tires themselves.

Ferrari 328 GTB tires should be replaced when they show age cracking, hardening, sidewall damage, repeated pressure loss, impact damage, or any structural concern, even if the tread still looks deep. Collector cars often age out tires long before they wear them out. That is particularly true for a performance-oriented car that may spend long stretches parked between drives.

Treat tread depth as only one part of the decision. On Ferrari 328 GTB, aged tires can undermine braking feel, steering response, and highway stability even when the car is driven conservatively. If there is any doubt about age or condition, have the tires evaluated by a specialist familiar with collector and performance applications before putting the car back into regular road use.

Ferrari 328 GTB is represented here by two metric radial sizes used across 1986 through 1989: 205/55R16 and 225/50R16. The available tire series include Michelin SX MXX3 N2, Michelin Pilot Sport, several BFGoodrich g-Force lines, and American Classic Radial in the front-size range. That establishes the size family clearly, while leaving room for different brand and series choices within it.

For a restoration-minded owner, the most useful path is to confirm the tire size first and then compare the visual character of the available tires with period photos, manuals, and marque references for the specific car. A Ferrari 328 GTB restored for judging may call for a different choice than one restored for active road use, even when both stay within the correct size range.

Correct tire fitment can matter on Ferrari 328 GTB because tire size, sidewall appearance, and overall stance contribute directly to how authentic the car looks and how properly it drives. Staying with the correct 205/55R16 and 225/50R16 size combination helps preserve the intended proportions. Visible departures in profile or sidewall style can change the car's presentation quickly.

For concours or serious preservation work, originality-minded owners usually treat tires as part of the car's overall restoration story. A Ferrari 328 GTB judged by marque specialists may benefit from a tire choice that aligns closely with the period look, while a road-focused example may lean toward a modern radial with similar dimensions. Clarify your goal before choosing between visual authenticity and pure road-use preference.

Ferrari 328 GTB tire options here include Blackwall and Wide Whitewall styles, but blackwall is the sidewall treatment that aligns naturally with the car's late-1980s high-performance character. Blackwall is also the only sidewall style listed in the wider 225/50R16 rear size. The wide whitewall choice exists only in the 205/55R16 size.

For most restorations, blackwall will be the sensible direction because it maintains the visual balance expected on a Ferrari 328 GTB. A whitewall front tire would create a custom look rather than a standard period Ferrari appearance. If authenticity is the priority, match the sidewall style to the era and keep the full set visually coherent from front to rear.

The listed Ferrari 328 GTB tires are modern radial designs in the correct 16-inch size family for the car, so they are appropriate candidates for public-road use when they are correctly fitted, properly inflated, and in sound condition. Safety depends on more than size alone, however. Tire age, condition, wheel condition, alignment, and the overall mechanical state of the car all matter.

A Ferrari 328 GTB that is driven regularly should have its tires evaluated as part of normal roadworthiness, not just cosmetic upkeep. Verify that the correct front and rear sizes are installed, inspect for age-related deterioration, and make sure the suspension and brakes are equally ready for use. On a collector Ferrari, a correct-size tire is only one part of a safe road setup.

Before driving a Ferrari 328 GTB, check that the tires are inflated correctly, free from visible cracking or damage, and matched correctly by size to the front and rear positions. Confirm that the 205/55R16 and 225/50R16 sizes have not been swapped across axles. Also inspect tread for uneven wear that could point to alignment or suspension issues.

Because the 328 GTB is a performance car with a staggered setup, a simple pre-drive walk-around is worth making a habit. Look for pressure loss after storage, signs of rubbing, or any evidence that a wheel or tire has been changed since the last drive. Those small checks can prevent poor handling and protect both the car and the tires.

Appropriate road speed for a Ferrari 328 GTB depends on the actual tire fitted, its age, its load and speed specification, and its condition today rather than the car's performance potential alone. The listed products include modern radial performance tires, but an older tire should never be treated as if it has full new-tire capability simply because the size is correct. Condition always governs safe use.

For practical driving, use a conservative approach until the tires, wheels, and chassis have all been inspected and the car has been road-tested gradually. A Ferrari 328 GTB can quickly expose weaknesses in old or poorly matched tires. If there is any uncertainty about age, storage history, or condition, keep speeds modest until a specialist has evaluated the complete setup.
