Ferrari 348 GTB Tires

Ferrari 348 GTB uses two tire sizes across the 1993 and 1994 model years: 215/50R17 and 255/45R17. Both sizes fit 17-inch wheels, but they are not interchangeable because the car uses a staggered arrangement with a narrower tire at one end and a wider tire at the other. The available 215/50R17 products list 17-inch rim diameter with recommended rim widths from 6.0 to 7.5 inches, while the 255/45R17 products list 17-inch rim diameter with fitments centered around wider rear wheels.

The practical step is to identify which axle you are replacing before choosing a tire. A Ferrari 348 GTB owner replacing all four tires should verify that the front wheels carry the narrower size and the rear wheels carry the wider size, then confirm the actual wheel dimensions on the car before matching a specific product.

On Ferrari 348 GTB, 215/50R17 is a metric radial tire size. The 215 is the nominal section width in millimeters, 50 is the aspect ratio showing the sidewall height as 50 percent of the width, R identifies radial construction, and 17 is the wheel diameter in inches. In the available Ferrari 348 GTB products, this size is paired with 17-inch wheels and recommended wheel widths from 6.0 to 7.5 inches.

That decoding matters because a 215/50R17 is not simply any 17-inch tire that looks close. On Ferrari 348 GTB, the width and profile are part of the intended staggered balance, so a buyer should match the full size code exactly and avoid substituting a nearby metric size unless the car is being set up with guidance from a knowledgeable Ferrari specialist.

A 1993 Ferrari 348 GTB has 2 tire sizes listed because the car uses a staggered tire package rather than four identical tires. The listed sizes are 215/50R17 and 255/45R17, and both mount on 17-inch wheels. The difference is width and profile, with one size intended for the narrower axle position and the other for the wider axle position.

That means the year alone does not identify the correct tire. A Ferrari 348 GTB owner should inspect the car axle by axle, verify the wheel width and the existing size markings, and then choose the proper tire for that position instead of assuming that either listed size will work at all four corners.

A 1994 Ferrari 348 GTB uses the same two sizes as the 1993 model year: 215/50R17 and 255/45R17, both on 17-inch wheels. Because Ferrari 348 GTB uses a staggered setup, the correct tire depends on axle position rather than model year alone. The narrower 215/50R17 and wider 255/45R17 each correspond to different wheel widths, so the wheel itself is part of the fitment check.

The most reliable approach is to read the size on the tire currently mounted, inspect the wheel width stamping if accessible, and compare both front and rear before replacing anything. That extra step helps preserve the intended stance and handling balance of Ferrari 348 GTB and reduces the risk of ordering the right diameter but the wrong axle size.

Ferrari 348 GTB tire offerings here include Blackwall, Redline, and RWL sidewall styles, although they are not spread evenly across both sizes. The 215/50R17 selections are blackwall radials, while the 255/45R17 size includes blackwall options as well as Pro-Trac Street Pro III versions with redline and raised white letter sidewalls. All of the listed Ferrari 348 GTB products are radial-construction tires sized for 17-inch wheels.

For a period-correct late-classic Ferrari appearance, blackwall is usually the most natural visual fit. A Ferrari 348 GTB owner considering redline or RWL should think of that as a deliberate styling change, especially since those sidewall treatments appear only in the wider 255/45R17 size and can alter the visual balance of the car.

Ferrari 348 GTB tires in these sizes are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both listed sizes, Nitto is offered in 255/45R17, and Pro-Trac appears in 255/45R17 with multiple sidewall presentations. That gives Ferrari 348 GTB owners a mix of mainstream radial performance choices and specialty styling-oriented options within the 17-inch fitment range.

Brand choice should follow the role of the car rather than name recognition alone. A Ferrari 348 GTB used mainly for road driving may call for a straightforward blackwall radial, while a car built around a custom visual theme may lead an owner toward the Pro-Trac redline or RWL option in the rear size.

Ferrari 348 GTB tires here appear in four distinct series: g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2, along with Pro-Trac Street Pro III in the wider 255/45R17 size. All are radial 17-inch tires, but they differ in brand family, tread approach, and sidewall presentation. The Pro-Trac Street Pro III also stands apart because it is offered with redline and raised white letter sidewalls rather than only blackwall styling.

That variety means Ferrari 348 GTB owners should compare the series by intended use and appearance, not just by matching the size code. If keeping the car visually close to its original late-classic look matters, blackwall options will usually be the most natural match, while the Pro-Trac choices appeal more to buyers who want a personalized period-performance presentation.

Ferrari 348 GTB should be stored on a clean, dry surface away from direct sunlight, ozone sources, and large temperature swings. Keeping the tires properly inflated while the car is parked helps preserve the shape of the casing, especially on a staggered setup where front and rear sizes carry different proportions. If the car sits for extended periods, moving it occasionally can help reduce flat spotting.

Collectors who keep a Ferrari 348 GTB parked for weeks at a time should make tire care part of routine storage, not an afterthought. A battery tender, a stable garage environment, and periodic pressure checks all work together, because even high-quality modern radials age more quickly when they sit under load, underinflated, or exposed to heat and sunlight.

Tires on a Ferrari 348 GTB should be inspected before regular driving and more carefully at least several times each season. On a low-mile collector Ferrari, age-related cracking, pressure loss, shoulder wear, and flat-spotting can matter as much as remaining tread depth. Because Ferrari 348 GTB uses different front and rear sizes, both axles should be checked individually rather than assumed to wear in the same way.

A useful habit is to inspect the sidewalls, tread face, and valve areas every time the car comes out of storage or before a longer drive. Ferrari 348 GTB owners should also pay attention to steering feel and vibration, since collector cars often reveal tire problems through changes in road feel before the issue becomes obvious in a quick visual walkaround.

Ferrari 348 GTB tires should be replaced when age, cracking, hardening, impact damage, repeated air loss, or visible distortion appears, even if the tread still looks deep. Collector cars often accumulate less mileage than modern daily drivers, so time and storage conditions can end a tire’s useful life before tread wear does. That is especially important on a performance car such as Ferrari 348 GTB, where the tire’s grip and structure are central to how the car behaves.

An owner should read the date codes, inspect all four tires closely, and treat age as seriously as wear. If a Ferrari 348 GTB has sat for long periods, a specialist tire inspection is worthwhile before putting the car back into regular road use, since an old-looking but lightly worn tire can still be the weakest part of the car.

Ferrari 348 GTB uses 215/50R17 and 255/45R17 tire sizes across the 1993 and 1994 years covered here, both on 17-inch wheels. The available replacements are all radial-construction tires, with blackwall products in both sizes and additional redline and RWL choices in the wider 255/45R17 size. That establishes the size pattern clearly, but the exact original brand and tread specification for a specific Ferrari 348 GTB should be checked against factory literature or marque references.

For restoration work, the most important first step is preserving the correct staggered sizing and overall visual character. A Ferrari 348 GTB owner aiming for a factory-style presentation will usually want the proper front and rear metric sizes with blackwall sidewalls, then refine the brand and tread choice according to period photos, books, and Ferrari club guidance.

Correct tire fitment can absolutely influence how a Ferrari 348 GTB is judged and how seriously a restoration is taken. On a car from this era, judges and knowledgeable buyers notice whether the staggered front and rear sizing has been preserved, whether the sidewall treatment suits the car, and whether the overall stance looks right on the original 17-inch wheel format. Even when the exact brand is less important than on an earlier car, visible fitment accuracy still matters.

That does not mean every Ferrari 348 GTB must wear the same tire for every purpose. A car prepared for concours-style presentation may favor the most visually appropriate blackwall radial in the correct paired sizes, while a regularly driven example may prioritize a modern radial series that still respects the intended front-to-rear fitment and proportions.

Ferrari 348 GTB tire options here include blackwall, redline, and raised white letter sidewalls, but blackwall is the sidewall style that most naturally suits a 1993 to 1994 Ferrari restoration. The narrower 215/50R17 choices are blackwall only, while the wider 255/45R17 size adds redline and RWL alternatives. That means a visually balanced, factory-appropriate Ferrari 348 GTB restoration will generally center on blackwall tires at both ends of the car.

Redline and RWL treatments are best understood as personalization choices rather than default restoration choices for Ferrari 348 GTB. If authenticity is the goal, the owner should preserve the correct staggered sizes first, then choose a blackwall radial that keeps the car’s late analog Italian appearance coherent from front axle to rear.

The listed Ferrari 348 GTB tires are modern radial tires in the correct 17-inch metric sizes used by the model years covered here, so they are fundamentally appropriate for public-road use when they are correctly matched to the wheel and axle position. Safety still depends on the condition of the individual tire, proper inflation, correct installation, and the mechanical state of the car itself. A staggered Ferrari 348 GTB also needs the correct size at each end to maintain predictable balance.

Before returning a Ferrari 348 GTB to regular road use, the owner should think of the tires as one part of a larger readiness check. Wheel condition, suspension health, alignment, and brake performance all matter, because even the right tire size cannot compensate for a collector Ferrari that has been sitting or has unresolved chassis issues.

Before driving a Ferrari 348 GTB, check that the car is wearing the correct 215/50R17 and 255/45R17 sizes in their proper positions, confirm tire pressures, and inspect each tire for cracking, punctures, bulges, or uneven wear. Since all listed Ferrari 348 GTB options here are radial 17-inch tires, wheel diameter mismatch is less likely than front-to-rear size confusion. Sidewall condition also matters, especially on collector cars that may sit for long periods between drives.

A careful pre-drive walkaround pays off on Ferrari 348 GTB because small issues often show up after storage. If the steering feels vague, the car pulls, or vibration appears at speed, stop and recheck the tires and wheels before assuming the problem is elsewhere, since staggered performance cars are especially sensitive to tire condition and setup.

Ferrari 348 GTB owners should not assume that a car’s performance reputation overrides the condition and age of the tires fitted to it. The appropriate speed is the speed that matches the installed tire’s condition, inflation, and load, along with the road environment and the mechanical condition of the car. Even with correctly sized 17-inch radial tires, an older Ferrari 348 GTB should be brought up to speed gradually after storage rather than driven hard immediately.

In practical terms, a Ferrari 348 GTB should be driven conservatively until the owner has confirmed that the tires are fresh, evenly worn, properly inflated, and free from age damage. Collector-car use often encourages lower annual mileage, but that makes inspection more important, because a lightly worn tire can still be a poor candidate for high-speed driving if age has compromised it.
