The 1992 Ferrari 348 TS belongs to an era when Ferrari road cars combined sharp Pininfarina wedge styling with a distinctly analog driving experience. As a targa-top version of the 348, the TS rewards owners who pay close attention to chassis balance, steering feel, and overall setup. Tire fitment is split between a 215/50R17 front and a 255/45R17 rear, both radial sizes on 17-inch wheels, so choosing the correct position-specific tire matters. Available options include blackwall selections up front and blackwall, redline, or raised white letter choices at the rear. For a restoration-minded owner or an active driver, the goal is matching appearance, wheel compatibility, and intended road use.
Which Tire Size Is Right for The 1992 Ferrari 348 TS
The 1992 Ferrari 348 TS uses two primary tire sizes, with one size for the front axle and another for the rear. Both are radial fitments on 17-inch wheels, so the first step is confirming whether you are replacing front or rear tires. The real decision after that is comparing the available product styles, brands, and sidewall treatments within the correct position-specific size.
The 215/50R17 size is a metric radial format in which 215 identifies nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 1992 Ferrari 348 TS, this is the front tire size, so it plays an important role in steering response and maintaining the intended staggered setup. Available choices in this size come from BFGoodrich in blackwall form across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size should be selected when replacing the front tires and matched carefully to the wheel width and overall vehicle setup.
The 255/45R17 size is also a metric radial, with 255 denoting nominal section width in millimeters, 45 describing the aspect ratio, and 17 marking the wheel diameter. On the 1992 Ferrari 348 TS, this is the rear tire size, giving the car its wider rear fitment and making axle position especially important during replacement. Choices in this size include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter sidewall treatments available. This is the correct size to evaluate for rear tire replacement, especially when appearance preferences matter alongside wheel compatibility.
Sub-model fitment is straightforward in one sense and position-specific in another, because both covered versions use the same front and rear tire sizes. Checking the exact front or rear position still matters, since the 348 TS uses a staggered setup rather than the same size at all four corners.

1992 Ferrari 348 TS Base Front
The 1992 Ferrari 348 TS Base Front uses the narrower front radial size in the staggered 17-inch setup. That makes front-tire selection more about choosing the right series and rim-width compatibility than deciding between multiple front fitments.
The 1992 Ferrari 348 TS Base Rear uses the wider rear radial size that completes the car's front-to-rear stagger. Rear replacement is where sidewall appearance choices become more visible, since blackwall, redline, and raised white letter options are available in this position.
The 1992 Ferrari 348 TS Series Speciale Front uses the same front radial tire size as the other covered front configuration. Tire selection here centers on maintaining the proper front position fitment and comparing the available blackwall performance-oriented series.
The 1992 Ferrari 348 TS Series Speciale Rear uses the same wider rear radial size as the other covered rear configuration. That gives the owner the same rear-tire decision path: confirm the rear wheel setup, then choose among available brands and sidewall styles.
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 1992 Ferrari 348 TS Tires for Sale
Available 1992 Ferrari 348 TS tire choices focus on two position-specific 17-inch radial sizes. The front 215/50R17 selection centers on BFGoodrich blackwall performance series, while the rear 255/45R17 range adds BFGoodrich, Nitto, and Pro-Trac options with blackwall, redline, and raised white letter sidewall styles.
Owners researching 1992 Ferrari 348 TS tires usually need to confirm the front and rear sizes first, then compare radial choices, wheel fitment, sidewall appearance, and pre-drive inspection points. The questions below focus on those exact decisions.
Tire Size & Fitment
What tire size fits a 1992 Ferrari 348 TS?
The 1992 Ferrari 348 TS uses a staggered tire setup, with 215/50R17 on the front and 255/45R17 on the rear. Both are radial tire sizes designed for 17-inch wheels, so this Ferrari does not use the same tire size at all four corners.
That front-to-rear difference means the first step is identifying axle position before choosing a tire. A front tire should be replaced with the correct front size and a rear tire with the correct rear size, while also confirming that the wheel diameter and width still match the intended tire after any past wheel or suspension changes.
What size rim does a 1992 Ferrari 348 TS use?
The 1992 Ferrari 348 TS uses 17-inch rims with both of its primary tire sizes. The front 215/50R17 and rear 255/45R17 are both built around a 17-inch wheel diameter, even though the tire widths and profiles differ between the two positions.
Wheel diameter is only part of the fitment picture, especially on a staggered car. It is also worth checking actual wheel width at each axle, since the available front and rear tires have different width ranges and are meant for different positions. That matters even more if the car has been fitted with aftermarket wheels over the years.
Do all 1992 Ferrari 348 TS sub-models use the same tire size?
The covered 1992 Ferrari 348 TS sub-models share the same tire setup by position. Both the Base and Series Speciale use 215/50R17 at the front and 255/45R17 at the rear, so the fitment pattern remains consistent across those versions.
The important distinction is not Base versus Series Speciale, but front versus rear. An owner replacing tires should still verify which axle is being serviced and confirm that the wheels on the car remain true to the 17-inch staggered arrangement. That helps avoid treating the car like a same-size setup when it is not.
Choosing the Right Tire
What should I consider when choosing a 215/50R17 and 255/45R17 tire for a 1992 Ferrari 348 TS?
Start with the correct axle-specific size, because the 1992 Ferrari 348 TS uses 215/50R17 in front and 255/45R17 in the rear. After size, the next factors are radial construction, wheel-width compatibility, sidewall appearance, brand, and tire series, since those are the main points of variation in the available choices.
A good selection process keeps the front and rear roles separate. The front choices are blackwall BFGoodrich performance-oriented series, while the rear selection broadens into BFGoodrich, Nitto, and Pro-Trac products with blackwall, redline, and raised white letter styling. Matching the tire to the wheel and the car's intended use is more important than choosing by name alone.
What sidewall styles are available for 1992 Ferrari 348 TS tires?
Sidewall style depends on tire size and position on the 1992 Ferrari 348 TS. The front 215/50R17 options are blackwall, while the rear 255/45R17 options include blackwall, redline, and RWL, which is a raised white letter sidewall treatment.
That gives the rear of the car more visual flexibility than the front. A blackwall approach keeps the appearance more understated, while redline or raised white letter sidewalls create a stronger period-inspired or custom look. Since those appearance choices are tied to the rear size, it helps to decide early whether the goal is subtle presentation or a more noticeable sidewall accent.
What brands offer tires for the 1992 Ferrari 348 TS?
The 1992 Ferrari 348 TS tire selection includes BFGoodrich, Nitto, and Pro-Trac, though not every brand appears in both sizes. BFGoodrich covers the front 215/50R17 choices and also appears in the rear 255/45R17 range, while Nitto and Pro-Trac are part of the rear-size assortment.
That means brand comparison should be done by axle position rather than across the car as a single universal size. It is also useful to compare each tire's series, sidewall style, and wheel-width suitability within the correct front or rear fitment. The right choice often comes down to balancing appearance and setup compatibility, not simply choosing a familiar brand name.
Restoration & Appearance
Which tire should I choose for a period-style 1992 Ferrari 348 TS?
A period-style 1992 Ferrari 348 TS starts with maintaining the correct staggered radial sizes: 215/50R17 in front and 255/45R17 in the rear. From there, the visual direction depends on whether the owner wants a restrained blackwall presentation or a more assertive rear-sidewall look through redline or raised white letter styling.
Because this is a 1990s performance Ferrari, overall stance and front-to-rear proportion matter as much as brand choice. Keeping the correct size relationship is usually the strongest first step for appearance. Owners pursuing strict originality may also want to compare current tire styling against period photos, marque references, and other model-specific historical material before making a final decision.
How does tire construction affect the appearance of a restored 1992 Ferrari 348 TS?
On the 1992 Ferrari 348 TS, the primary fitment is radial, so construction does not create a bias-ply-versus-radial appearance decision. The more visible appearance differences come from sidewall treatment, tire series, and maintaining the intended staggered front and rear sizing on 17-inch wheels.
That makes presentation more about details than about switching construction types. A blackwall tire keeps the look cleaner and more modern, while redline or raised white letter options add more visual presence at the rear. For a restoration-minded owner, preserving the proper front-to-rear size relationship usually does more for the car's overall look than chasing cosmetic differences alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1992 Ferrari 348 TS?
Yes, modifications can affect tire fitment on a 1992 Ferrari 348 TS even when the tire sizes remain 215/50R17 front and 255/45R17 rear. Changes such as aftermarket wheels, altered wheel widths, suspension adjustments, ride-height changes, or body modifications can all change how those tires sit and clear the car.
That is why a modified car should not be treated exactly like a stock-wheel example. It helps to confirm actual wheel diameter and width at each axle, then check steering clearance, inner suspension clearance, and fender space before selecting a replacement. A staggered setup leaves less room for guesswork because each axle has its own fitment requirements.
What should I inspect before driving a 1992 Ferrari 348 TS on new tires?
Before driving a 1992 Ferrari 348 TS on new tires, inspect wheel condition, verify the correct front and rear sizes, and confirm proper inflation for the tires installed. It is also wise to look over valve stems, bead seating, visible tread and sidewall condition, and any sign that the tires are contacting suspension or body components.
A short initial road test is useful for catching vibration, pulling, or clearance issues before a longer drive. Since the 348 TS uses different tire sizes front and rear, an owner should also confirm that the tires were mounted in the intended axle positions and that the wheels themselves are correctly placed. That simple check can prevent avoidable handling and fitment problems.
How should tires on a collector 1992 Ferrari 348 TS be maintained?
Tires on a collector 1992 Ferrari 348 TS benefit from regular pressure checks, periodic visual inspection, and careful storage habits. Even on a low-mileage car, tires should be examined for cracking, bulges, cuts, uneven wear, and slow air loss, because infrequent use can hide age-related issues until the car is back on the road.
Storage conditions matter nearly as much as mileage. Keeping the car away from prolonged heat, direct sunlight, excess moisture, and ozone-producing equipment helps preserve tire condition over time. It also helps to recheck front and rear tires separately before longer drives, since the 348 TS uses different sizes and each axle may show wear or pressure changes differently.
