The 1994 Ferrari 348 Spider sits at an interesting point in Ferrari road-car history, pairing open-top touring appeal with the sharp-edged, driver-focused character that defined the marque’s early 1990s V8 cars. Its stance and handling balance depend on a staggered tire setup rather than a one-size arrangement. This 348 Spider uses 215/50R17 front tires and 255/45R17 rear tires, both in radial construction on 17-inch rims. Available choices include blackwall performance radials up front, with blackwall, redline, and raised white letter options at the rear. The key is matching the correct front-to-rear sizing while choosing a tire style that suits the car’s road use and visual presentation.
Which Tire Size Is Right for The 1994 Ferrari 348 Spider
The 1994 Ferrari 348 Spider uses two primary tire sizes, and the difference is positional rather than trim-related: 215/50R17 for the front and 255/45R17 for the rear. Both are radial tires built for 17-inch rims, so the first step is confirming whether you are replacing the front pair, the rear pair, or a complete set while keeping the staggered setup intact.
In 215/50R17, the 215 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 1994 Ferrari 348 Spider, this is the front tire size, making it part of the car’s staggered factory-style layout. Available choices in this size center on BFGoodrich blackwall performance radials across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. Choosing this size correctly matters because the front axle requires its own dedicated fitment rather than the wider rear specification.
In 255/45R17, the 255 is the nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. This is the rear tire size for the 1994 Ferrari 348 Spider, giving the car the wider rear footprint expected from its staggered setup. Product choices include BFGoodrich and Nitto blackwall radials, along with Pro-Trac Street Pro III options in redline and RWL sidewall treatments. Selecting the proper rear size helps preserve the car’s intended front-to-rear balance and keeps appearance choices focused on the back axle where sidewall styling differs most.
Sub-model fitment on the 1994 Ferrari 348 Spider is straightforward, but tire position still matters because the front and rear do not use the same size. Checking whether you are working with the Base Front or Base Rear fitment keeps the staggered 17-inch setup properly matched.

1994 Ferrari 348 Spider Base Front
The Base Front position uses the narrower front radial fitment for the 1994 Ferrari 348 Spider. Tire selection here is mainly about choosing the right 17-inch front size and comparing available blackwall performance-oriented options without mixing in the wider rear specification.
The Base Rear position uses the wider rear radial fitment that completes the car’s staggered layout. That means rear tire selection should focus on the correct 17-inch rear size while comparing blackwall, redline, or raised white letter choices that affect both appearance and overall tire pairing.
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.

Tire Size & Fitment
What tire size fits a 1994 Ferrari 348 Spider?
The 1994 Ferrari 348 Spider uses a staggered tire setup with 215/50R17 on the front and 255/45R17 on the rear. Both sizes are radial tires designed for 17-inch rims, so this car does not use the same tire size at all four corners.
That staggered arrangement is the first thing to keep straight when replacing tires. A front replacement should stay with the 215/50R17 size, while a rear replacement should stay with 255/45R17 unless the car has been changed from its original wheel and suspension layout. Checking the wheel position before ordering helps avoid mixing front and rear fitments.
What size rim does a 1994 Ferrari 348 Spider use?
The 1994 Ferrari 348 Spider uses 17-inch rims with both of its primary tire sizes. The front 215/50R17 and rear 255/45R17 are both built around the same 17-inch wheel diameter, even though the tires differ in width and profile.
Wheel diameter is only one part of the fitment picture, so it is still worth confirming actual wheel width before choosing among available tires. The front and rear sizes are not interchangeable just because they share a 17-inch rim diameter. On a car with aftermarket wheels, verifying both diameter and width is especially important before mounting new tires.
Why does the 1994 Ferrari 348 Spider have more than one tire size?
The 1994 Ferrari 348 Spider has more than one tire size because it uses a staggered setup, with 215/50R17 at the front and 255/45R17 at the rear. The front and rear fitments are assigned by axle position rather than by separate trim levels.
For the owner, that means tire selection starts with identifying where the tire will be used. Front tires should be chosen from the 215/50R17 fitment and rear tires from the 255/45R17 fitment, while keeping wheel diameter and vehicle setup in mind. If the car has non-original wheels or suspension changes, checking clearance and wheel width becomes even more important.
Choosing the Right Tire
What should I consider when choosing a 215/50R17 and 255/45R17 tire set for a 1994 Ferrari 348 Spider?
Start with the basic layout: the 1994 Ferrari 348 Spider needs 215/50R17 front tires and 255/45R17 rear tires, both in radial construction on 17-inch rims. From there, the real comparison points are brand, tire series, sidewall style where available, and wheel-width compatibility for each axle.
A matched approach usually makes the most sense, especially on a car with distinct front and rear sizes. Front choices are centered on BFGoodrich blackwall performance radials, while the rear opens up BFGoodrich, Nitto, and Pro-Trac options, including redline and RWL styling. The best choice depends on whether the goal is a clean modern blackwall look or a more period-minded rear presentation.
What sidewall styles are available for 1994 Ferrari 348 Spider tires?
Sidewall styling for the 1994 Ferrari 348 Spider varies by tire size. The 215/50R17 front fitment is available in blackwall form, while the 255/45R17 rear fitment includes blackwall choices along with redline and RWL options.
That means sidewall appearance can become part of the decision, especially if the car is being finished with a more customized or period-flavored look. A blackwall set keeps the presentation understated and performance-oriented, while redline or raised white letter rear tires create a more noticeable visual statement. Keeping the front and rear styles coordinated usually produces the most intentional overall appearance.
What brands offer tires for the 1994 Ferrari 348 Spider?
The available brands for the 1994 Ferrari 348 Spider include BFGoodrich, Nitto, and Pro-Trac, depending on tire size and position. BFGoodrich appears in the front 215/50R17 size and also in the rear 255/45R17 size, while Nitto and Pro-Trac are offered in the rear fitment.
Brand choice should be considered alongside the size and style needed at each end of the car. BFGoodrich offers several g-Force series options, Nitto adds another blackwall rear radial choice, and Pro-Trac introduces rear styling options such as redline and RWL. The useful comparison is not just brand name, but how each offering fits the axle position and visual goal.
Restoration & Appearance
Which tire should I choose for a period-style 1994 Ferrari 348 Spider?
A period-style approach for a 1994 Ferrari 348 Spider starts with keeping the proper staggered radial sizes in place: 215/50R17 in front and 255/45R17 in the rear. From there, the choice usually comes down to whether the car should present with a restrained blackwall look or a more expressive rear sidewall treatment.
Blackwall tires tend to suit the clean, performance-focused character of an early 1990s Ferrari, while rear redline or RWL options move the car toward a more individualized appearance. Owners pursuing strict historical accuracy should compare any sidewall choice against period photos, marque references, or other Ferrari-specific documentation before settling on a final look.
How does tire construction affect the appearance of a restored 1994 Ferrari 348 Spider?
On the 1994 Ferrari 348 Spider, construction is less of an appearance debate than it is on older collector cars because the primary fitment is already radial. The visible difference comes more from sidewall treatment and tire series than from choosing between bias-ply and radial construction.
That makes details such as blackwall, redline, or raised white letter styling more important to the finished presentation. A blackwall tire keeps the look closest to a modern high-performance sports-car theme, while redline or RWL rear tires add a custom visual accent. Maintaining the correct front-and-rear size relationship is still the foundation of any restoration-minded tire choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1994 Ferrari 348 Spider?
Yes, modifications can affect tire fitment on a 1994 Ferrari 348 Spider, especially because the car uses different front and rear sizes. Aftermarket wheels, altered wheel widths, suspension changes, lowering, or body modifications can all change how a 215/50R17 front or 255/45R17 rear tire sits in the wheel opening.
Even when the tire size remains the same, wheel width and offset can influence clearance at the fender, suspension, and steering components. Any car that has been modified should have its wheel dimensions checked before new tires are installed. A quick inspection of lock-to-lock clearance at the front and loaded clearance at the rear can prevent expensive fitment mistakes.
What should I inspect before driving a 1994 Ferrari 348 Spider on new tires?
Before driving a 1994 Ferrari 348 Spider on new tires, confirm that the front 215/50R17 and rear 255/45R17 positions are correct and that the tires are mounted on the proper 17-inch wheels. It is also smart to inspect wheel condition, valve stems, and inflation pressure before the car goes back on the road.
A short follow-up inspection after initial driving is worthwhile on any collector or specialty car. Recheck pressure, look for any rubbing marks, and make sure the tire beads are seated properly with no air loss. Since older sports cars are often driven less frequently, it also helps to watch for uneven wear, vibration, or steering pull early rather than after several outings.
How often should tires on a 1994 Ferrari 348 Spider be inspected?
Tires on a 1994 Ferrari 348 Spider should be inspected regularly, especially if the car is driven infrequently or stored for long periods. A visual check before each drive is a good habit, with closer inspection for tread wear, cracking, cuts, bulges, and pressure loss performed on a routine basis.
Low-use collector cars can age tires out before they wear them out, so condition matters as much as mileage. It is wise to inspect the inside and outside sidewalls, verify that front and rear pressures remain stable, and look for signs of flat spotting after storage. Keeping the car away from prolonged heat, sunlight, and ozone sources also helps preserve tire condition.
