Ferrari 348 TB Tires

Ferrari 348 TB uses two tire sizes across the 1989 through 1992 model years: 215/50R17 and 255/45R17. Both sizes are radial constructions built for 17-inch rims. The 215/50R17 size is the narrower fitment, while 255/45R17 is the wider companion size used as part of the car’s staggered arrangement.

The practical step is to confirm whether you are replacing front tires, rear tires, or all four. Ferrari 348 TB does not use the same size at every corner, so ordering a full set without checking axle position can create a mismatch. If the car has aftermarket wheels, verify wheel width as well as diameter before choosing a tire.

On Ferrari 348 TB, the size code 215/50R17 means the tire is 215 millimeters wide, has a 50-series aspect ratio, uses radial construction, and fits a 17-inch rim. That combination appears across all listed years from 1989 to 1992. It is one half of the car’s staggered tire package rather than a universal four-corner fitment.

That decoding matters because modern metric sizing packs several dimensions into one line, and each one affects fit. A different width or aspect ratio can alter clearance, stance, and the relationship between front and rear tires. When replacing only two tires on Ferrari 348 TB, match the exact size already used on that axle rather than choosing by rim diameter alone.

A 1990 Ferrari 348 TB has 2 tire sizes listed because the model uses a staggered setup, with a narrower size and a wider size sharing the same 17-inch wheel diameter. The two sizes are 215/50R17 and 255/45R17. That split is not a year-to-year change or a construction change; it is part of the car’s front-to-rear tire arrangement.

The important implication is that year alone does not identify which tire you need. You also need to know whether the tire is for the front axle or the rear axle. If the car has been modified, compare the current wheel and tire combination to the actual axle before replacing a pair, since many collector Ferraris have seen wheel changes over time.

Ferrari 348 TB uses 17-inch rims for both listed tire sizes from 1989 through 1992. The 215/50R17 front-size products and the 255/45R17 rear-size products are all built around a 17-inch wheel diameter. There is no rim-diameter change across the production span covered here.

That simplifies selection because the main fitment difference is tire width and profile, not wheel diameter. Even so, confirm the actual wheel on the car if it has changed hands or been restored, since aftermarket wheels can alter both width and recommended tire range. Matching the tire to the correct 17-inch rim width is just as important as matching the diameter.

To confirm the correct tire size for a 1991 Ferrari 348 TB, start by identifying which axle needs tires. Ferrari 348 TB uses 215/50R17 and 255/45R17 across all listed years, with both sizes fitting 17-inch rims. The difference is not by production year but by the car’s staggered front-and-rear arrangement.

Check the existing tire sidewall, measure the wheel if needed, and compare the wheel width to the recommended range for the replacement tire. That matters most when the car may have aftermarket wheels or when only one axle is being replaced. On a Ferrari 348 TB, choosing by year alone is not enough; axle position and wheel width finish the fitment check.

Ferrari 348 TB tires are available here in Blackwall, Redline, and RWL sidewall styles. Blackwall appears on both listed sizes, while the 255/45R17 rear size also includes Redline and RWL options. Those sidewall treatments change appearance rather than the basic metric size itself.

For a more restrained late-classic sports car look, Blackwall is the most neutral presentation. Redline or raised white letters create a more custom visual effect and may appeal to owners building around personal style rather than strict factory appearance. If matching an existing set on Ferrari 348 TB, confirm both the size and the sidewall style so front and rear presentation stays consistent.

Ferrari 348 TB tire options here come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both listed sizes, while Nitto and Pro-Trac appear in the 255/45R17 rear size. All available products for Ferrari 348 TB in this set are radial 17-inch tires.

Brand choice becomes part of the decision once size and axle position are settled. Some owners prefer to keep the same brand front and rear for a more uniform setup, while others prioritize a particular rear-tire look or tread family. The right approach on Ferrari 348 TB is to first lock in size, then compare brand, sidewall style, and wheel-width compatibility.

Ferrari 348 TB tire series available here include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III. All are radial 17-inch tires, but they represent different product families from their respective brands. The main distinctions in this set are brand line, sidewall presentation, and which of the two Ferrari 348 TB sizes each series covers.

That means the first decision is still fitment, not series name. Once you know whether you need 215/50R17 or 255/45R17, you can compare which series are offered in that exact size and whether you want Blackwall, Redline, or RWL styling. On a staggered Ferrari 348 TB, some series may be available on one axle size and not the other, so compare the pair together.

Ferrari 348 TB should be stored on clean, properly inflated tires in a cool, dry, dark environment away from direct sunlight, electric motors, and ozone sources. If the car will sit for extended periods, moving it slightly from time to time helps reduce flat spotting. A clean garage floor or tire cradles can also help protect the tire casing during storage.

Collector cars often age tires by time and environment more than by mileage, and Ferrari 348 TB is no exception. Keep inflation checked during storage, avoid parking for months on a soft or oil-contaminated surface, and inspect the sidewalls when bringing the car back into use. Good storage habits preserve both appearance and driving quality on a low-use car.

Tires on a Ferrari 348 TB should be visually inspected before each drive and more thoroughly at regular service intervals. Look for cracking, punctures, bulges, uneven wear, and any signs that the front and rear tires are aging differently. Because Ferrari 348 TB uses a staggered setup, each axle should be checked with its own size and wear pattern in mind.

Frequent inspection matters because collector cars may sit long enough for age-related issues to appear before tread is worn down. Check inflation pressures, inspect the inner and outer sidewalls, and pay attention to any vibration or steering change on the road. Catching an aging or damaged tire early is far easier than correcting a problem after it affects handling or the wheel.

Tires on a Ferrari 348 TB should be replaced when age, cracking, hardening, impact damage, or structural concerns appear, even if tread depth still looks usable. Collector-car tires often time out before they wear out, especially when the car sees occasional use. Any tire that shows visible deterioration or drives abnormally deserves immediate evaluation.

The practical rule is to treat tread depth as only one part of the decision. Ferrari 348 TB depends on predictable grip and balanced front-to-rear behavior, so old tires can compromise the driving experience long before they look worn. If the car’s history is unclear, start with a careful inspection of date codes, sidewalls, and overall condition before putting meaningful road miles on it.

Ferrari 348 TB is shown here with two metric radial sizes used from 1989 through 1992: 215/50R17 and 255/45R17. The available replacement products are all modern radial tires built for 17-inch wheels. That establishes the size format and staggered layout, but original brand and exact factory-issued tire specification should be verified from Ferrari literature for the specific car.

For restoration work, size and overall presentation are the first priorities. A Ferrari 348 TB restored for driving may reasonably use current radial replacements in the correct sizes, while a stricter authenticity project may require closer research into period manufacturer markings and approval references. Ferrari club sources, handbooks, and marque specialists are the best places to refine that last layer of originality.

Correct tire fitment can affect both presentation and credibility on a Ferrari 348 TB, especially when the car is being judged or represented as carefully restored. Using the proper staggered size relationship and appropriate sidewall appearance helps the car look coherent and mechanically sorted. Even on later collector cars, visibly incorrect sizing can stand out quickly.

For most owners, the practical goal is to preserve the car’s intended stance and avoid obvious departures from the proper front-and-rear arrangement. A Ferrari 348 TB prepared for shows or marque events should be checked against period references and club standards, particularly if the car wears nonstandard wheels. Correct fitment supports both drivability and the impression of an honest, well-researched car.

Ferrari 348 TB tire options here include Blackwall, with Redline and RWL also offered in the 255/45R17 rear size. For a restoration-minded car from the late 1980s and early 1990s, Blackwall is the most restrained and period-consistent choice among the available sidewall styles. Redline and raised white letters create a more custom appearance than a factory-minded one.

That does not make the alternate sidewalls wrong for every owner; it simply places them in a different visual category. If the goal for a Ferrari 348 TB is originality or marque-event presentation, keep the sidewall treatment subtle and consistent across the set. If the goal is personal style, select the sidewall that suits the car’s presentation while keeping the size pairing correct.

The available Ferrari 348 TB tires listed here are modern radial designs in the correct 17-inch metric sizes, which makes them appropriate candidates for public-road use when they are correctly matched to the car and in proper condition. Safety still depends on the individual tire’s age, inflation, condition, and wheel compatibility. A correct size alone does not make an aged or damaged tire roadworthy.

Before regular driving, make sure the front and rear sizes are on the proper axles, inspect for age-related deterioration, and verify that wheel widths fall within the tire maker’s recommended range. Ferrari 348 TB is sensitive to tire condition because of its performance character and staggered setup. A fresh, properly fitted set supports the car far better than a mismatched or aging one.

Before driving a Ferrari 348 TB, check that 215/50R17 tires are fitted where the narrower size belongs and 255/45R17 tires where the wider size belongs, then inspect inflation, tread condition, and sidewalls. Confirm that each tire is seated on a 17-inch rim and that there are no visible cracks, punctures, bulges, or signs of rubbing. Also look for uneven wear that might point to alignment or suspension issues.

Those quick checks matter because a staggered Ferrari 348 TB relies on the correct relationship between front and rear tires. If one axle has older tires or a different type than the other, the car’s balance can change noticeably. A few minutes in the garage before a drive can prevent poor behavior on the road and help preserve both the tires and the wheels.

Speed for a Ferrari 348 TB should always be governed by the actual tire fitted to the car, not by the car’s capability alone. The available replacements in these sizes include modern ZR-designated radial sizes, but any tire’s safe use depends on condition, inflation, and whether the tire is an old carryover or a fresh production example. An aged tire should never be treated like a new one simply because the size is correct.

The practical approach is to drive within the limits of the specific tires currently mounted and to be conservative until their age, condition, and setup are verified. On a Ferrari 348 TB, that means avoiding high-speed use on unknown or long-stored tires and reassessing after inspection and proper inflation. Tire condition, not just size code, should set the pace.
