1994 Ferrari Tire Fitment Guide

1994 Ferrari vehicles use six sizes across three model families. The 348 GTB, 348 GTS, and 348 Spider use 215/50R17 front and 255/45R17 rear. The 512 TR uses 235/40R18 front and 295/35R18 rear. The F355 Berlinetta and F355 GTS use 225/40R18 front and 265/40R18 rear. Rim-width guidance is available for 215/50R17 at 6.0 to 7.5 inches, 255/45R17 at 8.0 to 9.5 inches, 235/40R18 at 8.0 to 9.5 inches, 225/40R18 at 7.5 to 9.0 inches, and 265/40R18 at 9.0 to 10.5 inches.

The practical takeaway is that year and make alone are not enough for a 1994 Ferrari. You need the exact model first, and then you need to keep the correct front-and-rear stagger for that model family. A 348 owner is dealing with 17-inch tires, while 512 TR and F355 owners are in 18-inch fitments, but those two cars still do not share the same widths and profiles. Checking the wheel diameter and the current front and rear sidewall markings before ordering is the safest starting point.

On a 1994 Ferrari, 215/50R17 is a modern metric radial size. The 215 is the nominal section width in millimeters, 50 is the aspect ratio, meaning the sidewall height is 50 percent of that width, R identifies radial construction, and 17 is the wheel diameter in inches. Within the 1994 Ferrari range, this size is used on the front of the 348 GTB, 348 GTS, and 348 Spider.

That decoding matters because it tells you this is not a universal Ferrari size from the period. It is the narrower front half of a staggered 348 package, and it belongs with a 255/45R17 rear rather than with any of the 18-inch fitments used on the 512 TR or F355. If your car has aftermarket wheels or a previous owner changed tire brands, confirm both sidewall markings and wheel diameter before you assume the car still wears its intended setup.

No, 1994 Ferrari models do not all use the same tire size. The 348 family shares one staggered 17-inch pairing, the 512 TR uses its own staggered 18-inch pairing, and the F355 Berlinetta and F355 GTS share a different staggered 18-inch pairing. Even where two model families both use 18-inch wheels, the actual widths and aspect ratios are different.

That means model identification is the first fitment step on a 1994 Ferrari page like this one. A buyer shopping only by year and make can easily land on a size that looks close but is wrong for the car’s intended balance. Once you confirm whether the car is a 348, 512 TR, or F355, keep the proper front-and-rear combination together instead of selecting one axle size in isolation. That preserves wheel-diameter compatibility and avoids mismatched proportions.

Most 1994 Ferrari sizes are available as blackwall radials, which suits the understated, high-performance look expected on 1990s Ferraris. The 215/50R17, 235/40R18, 225/40R18, and 265/40R18 options stay in blackwall form. The 255/45R17 and 295/35R18 sizes add redline and raised white letter choices through Pro-Trac, giving those rear sizes a more visual, custom-oriented appearance than the blackwall options.

For a factory-style presentation, blackwall is the natural choice for a 1994 Ferrari. Redline or RWL treatment changes the look more dramatically and tends to appeal to owners building around personal style rather than strict Ferrari presentation. If appearance matters as much as fitment, choose the sidewall style only after confirming your model’s correct size pair, since those alternate sidewall treatments are not available across every front and rear size used in the 1994 Ferrari range.

1994 Ferrari tire coverage here comes from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across every size except the 295/35R18, Nitto covers 255/45R17, 235/40R18, and 225/40R18, and Pro-Trac supplies 255/45R17 and 295/35R18. That means a 348 owner has access to all three brands at the rear, a 512 TR owner sees BFGoodrich or Nitto at the front and Pro-Trac at the rear, and an F355 owner finds BFGoodrich or Nitto at the front with BFGoodrich at the rear.

Brand choice on a 1994 Ferrari often comes down to how closely you want to balance appearance, speed rating, and size availability across a staggered setup. Some owners prefer to stay with a single brand where possible, while others prioritize the correct dimensions first and then work within the brands available for each axle. Because the 512 TR and F355 rear sizes are more specialized than the fronts, it helps to start at the rear axle and then choose the matching front accordingly.

On 1994 Ferrari front sizes where both brands appear, BFGoodrich and Nitto overlap closely in fitment but differ in range and speed-rating spread. In 235/40R18, BFGoodrich offers W-rated options and a Y-rated g-Force Phenom T/A, while Nitto’s NT555 G2 is W-rated. In 225/40R18, BFGoodrich and Nitto both offer blackwall radials, with rim-width coverage centered around 7.5 to 9.0 inches. In 255/45R17 rear fitment, Nitto reaches a higher load figure than the BFGoodrich option shown there.

For a 1994 Ferrari owner, those differences matter less as brand hierarchy and more as specification detail. If you are comparing otherwise similar front tires, the useful questions are whether you want the available speed-rating ceiling in a given size, whether the recommended rim-width range matches your wheel, and whether you prefer to keep the same brand across both axles. Those are smarter comparison points than brand name alone on a staggered Ferrari fitment.

Rim-width guidance varies by size on a 1994 Ferrari. The 215/50R17 front size fits 6.0 to 7.5-inch rims, 255/45R17 fits 8.0 to 9.5-inch rims, 235/40R18 fits 8.0 to 9.5-inch rims, 225/40R18 fits 7.5 to 9.0-inch rims, and 265/40R18 fits 9.0 to 10.5-inch rims. Some products express the same range with a preferred measuring width inside parentheses, but the usable spread stays within those general bounds.

That range matters because a tire can share the correct diameter and still be wrong for the wheel if the rim is too narrow or too wide. Ferrari owners also need to remember that many cars in this era have seen aftermarket wheel changes. Before you settle on a tire, verify the actual wheel width on the car rather than assuming it remains factory spec. That check is especially important on rear tires, where the widths are much more substantial.

The 1994 Ferrari tires covered here are radial fitments without tube-type markings in the size descriptions. That strongly points to tubeless-style application across these modern 17-inch and 18-inch sizes rather than a tube-type setup associated with much earlier wheels and tire constructions. No size here shows the kind of TT marking that would identify an all tube-type application.

Even so, wheel condition still matters. A tubeless radial depends on a clean bead seat, a sound valve stem, and a wheel that seals properly. If your 1994 Ferrari still has original wheels, inspect for age-related corrosion, prior repairs, or finish damage before mounting new tires. That is a much more relevant setup question here than tube fitment, since the sizes themselves belong to an era when tubeless radial construction was standard practice on exotic road cars.

Original 1994 Ferrari wheels can only be used with the tire sizes intended for that specific model family and axle. The 348 sizes are both 17-inch, while the 512 TR and F355 sizes are all 18-inch, so there is no cross-compatibility between those wheel diameters. Even among the 18-inch cars, the front and rear widths differ enough that the full range should not be treated as interchangeable.

That means the wheel question has two parts: first confirm diameter, then confirm width. A 348 owner can stay within the correct 17-inch front-and-rear pair, but that does not mean those tires belong on a 512 TR or F355 simply because the brand names overlap elsewhere in the range. If your car has replacement wheels, measure them directly and compare that width to the recommended range for the exact size you plan to use.

A 1994 Ferrari should be stored in a cool, dry space away from direct sunlight, electric motors, welders, furnaces, and other ozone sources that can age rubber. Keep the tires clean, maintain proper inflation, and avoid leaving the car parked on damp surfaces for long periods. Because these are low-profile radials rather than bias-ply tires, they are generally less prone to severe flat-spotting than older constructions, but long static storage can still affect ride quality.

Collectors who leave a Ferrari parked for extended stretches usually benefit from moving the car periodically or supporting it in a way that reduces continuous load on one contact patch. The goal is to preserve both the tire and the wheel finish while avoiding stress from underinflation. If the car is stored for months at a time, include the spare in your inspection routine as well, since a spare that has aged out can leave you stranded even if the road tires still look presentable.

On a 1994 Ferrari, tire age matters more than mileage in most collector use. A sensible rule is to evaluate tires closely once they reach five to seven years of age and to give serious replacement consideration by around ten years, even if tread depth still looks strong. The DOT date code on the sidewall is the quickest way to determine the actual age of the tire rather than the age of the car or wheel.

That approach is especially important on exotic cars that may see only occasional driving. Heat cycles, storage conditions, and long periods of inactivity can age a tire without wearing it out in the usual sense. A 1994 Ferrari that spends most of its life indoors can still be riding on rubber that has hardened beyond what you want for confident road use. Age out the tire by condition and date, not by mileage alone.

Tires on a 1994 Ferrari should be inspected before every drive and more thoroughly before any extended outing. Look for sidewall cracking, cuts, bulges, uneven wear, punctures, and any sign that the tire has been run underinflated. Because these cars use staggered fitments, compare both front tires to each other and both rear tires to each other rather than assuming a problem will show up evenly across the whole set.

That habit is valuable because a lightly used Ferrari can develop problems while standing still, not just while accumulating miles. Pressure loss, age cracking, and wheel-seal issues can all appear between drives. On a longer trip, include the valve stems and the spare in the inspection and verify pressures when the tires are cold. Catching one weak tire early is far easier than dealing with a problem after the car is fully loaded and away from home.

Yes, the radial tires used on 1994 Ferrari models can be appropriate for highway driving when they are the correct size, in good condition, and inflated properly. Most of the sizes here appear in W-rated form, which carries a 112 mph ceiling, while some BFGoodrich g-Force Phenom T/A applications in 235/40R18 and 265/40R18 are Y-rated at 186+ mph. Those ratings are well above normal U.S. highway speeds, provided the tires are not aged out or damaged.

The more meaningful limit on many older exotic cars is often the condition of the whole vehicle rather than the speed symbol alone. Brakes, suspension bushings, alignment, and the state of the wheels all matter on a 1994 Ferrari, especially one that has spent years in collector storage. Highway use becomes a question of overall readiness, not just whether the tire carries an exotic-looking speed code. Confirm the tire age and condition before relying on any speed rating.

Inflation pressure on a 1994 Ferrari should start with the vehicle manufacturer’s recommendation for the exact model and axle, then be checked against the tire’s own sidewall information and load rating. Some sizes here show maximum load figures at 50 or 51 psi, including 215/50R17 at 1,521 pounds at 50 psi, 255/45R17 up to 1,874 pounds at 50 psi, 235/40R18 up to 1,521 pounds at 50 psi, 225/40R18 up to 1,389 pounds at 50 psi, and 265/40R18 at 1,819 pounds at 50 psi.

Those maximum load-and-pressure figures are not the same thing as the pressure you should automatically run on the car. They tell you the tire’s capacity ceiling, not the chassis setting Ferrari intended for ride, handling, and wear. Use the original owner’s manual or factory placard for the target pressure by axle, then verify the tire is suitable for that use. Do not transfer one size’s pressure assumption to another, because the front and rear tires are doing different jobs on these cars.

Before a longer drive in a 1994 Ferrari, inspect each tire for cracking, cuts, bulges, punctures, unusual wear, and any sign of prior curb or pothole damage. Check cold pressures, confirm the front and rear sizes match the car’s intended stagger, and make sure the valve stems and wheel sealing surfaces are in good shape. Include the spare if the car carries one, because long-stored spares often age unnoticed.

That tire inspection should be part of a broader pre-drive routine on any 1990s Ferrari. A longer trip places sustained heat and speed into the tire, and it also tests cooling, braking, and suspension components that may seem fine on short local drives. If the car has recently changed hands or has sat for a long period, a wheel-off inspection by a knowledgeable technician is a smart precaution. Good tires help, but they are only one part of roadworthiness.
