The 1992 Ferrari 348 TB belongs to an era when Ferrari road cars paired sharp wedge-era styling with a distinctly analog driving feel. As a mid-engine Berlinetta, the 348 TB relies heavily on correct staggered tire fitment to preserve the balance, stance, and steering response enthusiasts expect from the car. This model uses 215/50R17 front tires and 255/45R17 rear tires, both in radial construction on 17-inch wheels. Available choices include modern blackwall performance radials as well as rear options with redline or raised white letter styling. The real task is keeping the front-to-rear sizing relationship intact while choosing the look and driving character that suits the car.
Which Tire Size Is Right for The 1992 Ferrari 348 TB
The 1992 Ferrari 348 TB uses two primary tire sizes, with a staggered setup that places one size on the front axle and a wider size on the rear. Both are radial tires for 17-inch wheels, so the first step is confirming whether you are replacing the front pair, rear pair, or all four tires while maintaining the correct axle-specific fitment.
In 215/50R17, the 215 identifies the tire's nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 1992 Ferrari 348 TB, this size serves the front axle and plays an important role in steering precision and overall balance. Available choices in this size come from BFGoodrich across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, all with blackwall styling. Choosing this size means focusing on the correct front fitment first, then comparing series character and wheel-width compatibility.
In 255/45R17, the 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 1992 Ferrari 348 TB, this wider size is used at the rear, where it supports the car's staggered layout and visual stance. Choices include blackwall performance radials from BFGoodrich and Nitto, along with Pro-Trac Street Pro III options in redline and RWL sidewall treatments. Selecting this size calls for rear-axle focus, with attention to sidewall appearance, tire series, and wheel compatibility.
Fitment stays consistent across the covered 1992 Ferrari 348 TB configurations, with the same staggered sizing used on both Base and Series Speciale applications. What matters most is confirming whether the tire is for the front or rear axle, since the two positions use different sizes.

1992 Ferrari 348 TB Base Front
The 1992 Ferrari 348 TB Base Front uses the front portion of the car's staggered radial setup, centered on 215/50R17. Tire selection here is mainly about preserving correct front fitment while comparing available series choices and staying within the wheel's intended width range.
The 1992 Ferrari 348 TB Base Rear uses the wider rear tire position in the staggered setup, centered on 255/45R17. That makes rear tire choice as much about maintaining the proper front-to-rear relationship as it is about selecting blackwall, redline, or raised white letter styling.
The 1992 Ferrari 348 TB Series Speciale Front follows the same front radial fitment pattern as the Base configuration, using 215/50R17. The practical decision is choosing among the available front tire series without disturbing the car's intended staggered balance.
The 1992 Ferrari 348 TB Series Speciale Rear uses the same 255/45R17 rear radial size as the Base rear application. That keeps tire selection focused on the correct rear size first, then on whether a blackwall, redline, or RWL presentation best suits the car.
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.

Common 1992 Ferrari 348 TB tire questions usually come down to staggered front and rear sizing, 17-inch rim fitment, available radial choices, sidewall appearance, and the checks worth making before putting a collector Ferrari back on the road.
Tire Size & Fitment
What tire size fits a 1992 Ferrari 348 TB?
The 1992 Ferrari 348 TB uses a staggered tire setup, with 215/50R17 on the front and 255/45R17 on the rear. Both sizes are radial tires for 17-inch wheels, so the car does not use one uniform size at all four corners.
That staggered arrangement is central to the car's fitment and appearance, so front and rear tires should be selected by axle position rather than by model name alone. Before replacing tires, confirm which pair you need and make sure the wheel dimensions and current vehicle setup still match the original front-to-rear sizing layout.
What size rim does a 1992 Ferrari 348 TB use?
The 1992 Ferrari 348 TB uses 17-inch rims with both of its primary tire sizes. The front 215/50R17 and rear 255/45R17 share the same rim diameter, even though the rear tire is substantially wider than the front.
Matching rim diameter alone is not enough when replacing tires on a staggered car like the 348 TB. The wheel's actual width still matters, especially because the front and rear tire sizes are designed for different width ranges. Checking the wheel size at each axle helps avoid choosing a tire that is correct in diameter but wrong for the wheel.
Do all 1992 Ferrari 348 TB sub-models use the same tire size?
The covered 1992 Ferrari 348 TB sub-models use the same staggered tire sizing by axle position. Both the Base and Series Speciale configurations use 215/50R17 on the front and 255/45R17 on the rear.
That makes the fitment question more about front versus rear location than about trim differences. A buyer still needs to confirm whether the car retains its original wheel setup, because aftermarket wheels or prior tire substitutions can change what is currently mounted. Keeping the same front and rear sizing relationship is the safest starting point when selecting replacements.
Choosing the Right Tire
What should I consider when choosing a 215/50R17 and 255/45R17 tire set for a 1992 Ferrari 348 TB?
Start with the correct staggered sizing, since the 1992 Ferrari 348 TB uses 215/50R17 in front and 255/45R17 in the rear. From there, compare tire series, sidewall treatment where applicable, and whether the tires match the wheel-width requirements for each axle.
A balanced set matters on a car like the 348 TB because front and rear tires do different jobs. The front choice affects steering feel and the rear choice affects the car's planted stance and traction behavior. It also helps to think about how the car is used, whether for occasional fair-weather driving, regular road use, or a more appearance-focused presentation.
What sidewall styles are available for 1992 Ferrari 348 TB tires?
Sidewall style varies by size on the 1992 Ferrari 348 TB. The available 215/50R17 front tires are blackwall, while the 255/45R17 rear size is available in blackwall as well as redline and RWL, which is raised white letter styling.
That means appearance can be tuned mainly through the rear tires while keeping the correct staggered sizing in place. Buyers interested in a more understated look may stay with blackwalls front and rear, while those seeking a more custom or period-influenced presentation may want to compare the rear redline and raised white letter options carefully.
What brands offer tires for the 1992 Ferrari 348 TB?
Tires for the 1992 Ferrari 348 TB are available from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both front and rear fitments, Nitto is available in the rear size, and Pro-Trac offers rear options with alternate sidewall styling.
Brand choice should be weighed alongside tire size, series, and sidewall presentation rather than treated as the only decision. The front and rear positions do not have the same product mix, so many buyers end up choosing based on the complete set they want to build. Wheel-width compatibility and the intended look of the car should stay part of that decision.
Restoration & Appearance
Which tire should I choose for a period-style 1992 Ferrari 348 TB?
A period-style 1992 Ferrari 348 TB starts with the correct staggered radial sizing: 215/50R17 front and 255/45R17 rear. From there, the choice depends on whether the goal is a restrained blackwall performance look or a more expressive rear sidewall treatment such as redline or raised white letter.
Because appearance preferences vary, the best match is usually the one that keeps the car's proportions intact without overpowering its original design language. Buyers pursuing strict restoration accuracy should compare any styling choice against marque-specific references, while those building a driver can focus more on preserving the proper front-to-rear relationship and overall presentation.
Does correct tire fitment matter for a 1992 Ferrari 348 TB restoration?
Correct tire fitment matters a great deal on a 1992 Ferrari 348 TB restoration because the car uses a distinct front and rear size combination rather than a square setup. Keeping 215/50R17 in front and 255/45R17 in the rear helps preserve the visual stance and the basic fitment logic of the car.
Restoration-minded buyers should also pay attention to sidewall presentation, since blackwall, redline, and raised white letter choices can change the finished look noticeably. Tire selection should support the character of the build, but the first priority remains proper size and wheel compatibility. Appearance works best when it follows sound fitment rather than replacing it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1992 Ferrari 348 TB?
Yes, modifications can affect tire fitment on a 1992 Ferrari 348 TB even when the tire sizes appear correct on paper. Changes such as aftermarket wheels, altered wheel widths, suspension modifications, or ride-height adjustments can influence clearance and how the staggered front-to-rear setup sits on the car.
A modified 348 TB should be checked at both axles before new tires are selected. The key points are wheel diameter, wheel width, and whether the tire clears suspension components, steering travel, and bodywork. A tire that matches the original size code still needs to suit the actual wheel and chassis setup currently on the car.
What should I inspect before driving a 1992 Ferrari 348 TB on new tires?
Before driving a 1992 Ferrari 348 TB on new tires, inspect the wheels, valve stems, and overall wheel condition, then confirm that the front and rear tires are mounted in the proper staggered positions. It also makes sense to verify inflation, look for any rubbing points, and make sure the tires seat correctly on the rims.
A collector Ferrari may have sat for long periods, so the surrounding condition matters almost as much as the tires themselves. Check suspension wear, alignment behavior, and any signs of prior contact inside the wheel wells. A careful post-installation inspection and a short initial road test can reveal issues before longer or faster driving.
How should 215/50R17 and 255/45R17 tires on a collector 1992 Ferrari 348 TB be maintained?
Collector-car tires on a 1992 Ferrari 348 TB should be maintained with regular pressure checks, routine visual inspection, and clean, dry storage conditions. The front 215/50R17 and rear 255/45R17 tires should also be watched for sidewall cracking, tread damage, bulges, and uneven wear that may point to alignment or suspension issues.
Low annual mileage does not eliminate tire aging, especially on a car that spends long periods parked. Keeping the car away from prolonged sunlight, excess heat, and ozone sources can help protect the rubber over time. It is also wise to inspect the tires before each driving season and before any longer trip, even if the tread still looks usable.
