1998 Ferrari Tire Fitment Guide

1998 Ferrari vehicles use six sizes across three fitment families. The 456 GT and 456 GTA use 255/45R17 front and 285/40R17 rear on 17-inch wheels. The 550 Maranello uses 255/40R18 front and 295/35R18 rear on 18-inch wheels. The F355 F1, F355 GTS, and F355 Spider use 225/40R18 front and 265/40R18 rear on 18-inch wheels. Where rim-width guidance is available, 255/45R17 fits 8.0 to 9.5-inch rims, 285/40R17 fits 9.5 to 11.0, 255/40R18 fits 8.5 to 10.0, 225/40R18 fits 7.5 to 9.0, and 265/40R18 fits 9.0 to 10.5.

That means year and make are only the starting point for a 1998 Ferrari. You need to identify the exact model first, then confirm whether you are choosing the front or rear tire, because every fitment here is staggered. If the car has aftermarket wheels, verify the actual rim width before selecting a tire, especially on the wider rear applications where acceptable wheel width matters just as much as diameter.

On a 1998 Ferrari, 255/45R17 is a metric radial size. The 255 is the nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On 1998 Ferrari applications, that size belongs to the 456 GT and 456 GTA as the front tire, and available tires fit rim widths from 8.0 to 9.5 inches.

Reading the code correctly helps you avoid one of the most common mistakes on late-1990s exotics: matching diameter but missing width or profile. A 255/45R17 is not interchangeable with the 255/40R18 used on the 550 Maranello, even though both share the same nominal width. The sidewall height and wheel diameter are different, so the correct model identification matters before you compare brands or sidewall styles.

No. 1998 Ferrari models break into three distinct size groups. The 456 GT and 456 GTA share 255/45R17 and 285/40R17, the 550 Maranello uses 255/40R18 and 295/35R18, and the F355 F1, F355 GTS, and F355 Spider share 225/40R18 and 265/40R18. Every one of those combinations is staggered, so front and rear sizes are different even within the same model family.

That split has a practical effect when you begin tire research. A buyer with a 1998 Ferrari cannot safely shop by year alone, and even two V12 cars from the same year do not share the same wheel diameter. The quickest path is to confirm the model badge, then check the actual tire mounted at each axle so you can compare the right products for the correct front and rear positions.

Sidewall style varies by size on 1998 Ferrari applications. Blackwall choices cover 255/45R17, 285/40R17, 255/40R18, 225/40R18, and 265/40R18, while the 255/45R17 and 295/35R18 also offer Redline and RWL versions through Pro-Trac. That means cosmetic choice is widest on selected 456 and 550 Maranello sizes, while the F355 sizes stay firmly in modern Blackwall territory.

For a late-1990s Ferrari, Blackwall is the most era-appropriate visual direction for an original-style presentation. Redline or raised white letter sidewalls create a more custom look and can significantly change the appearance of the car even when the size remains correct. If authenticity matters, keep the car's period and market character in mind before choosing a decorative sidewall treatment.

BFGoodrich, Nitto, and Pro-Trac cover 1998 Ferrari fitments. The 255/45R17 for the 456 is available from BFGoodrich, Nitto, and Pro-Trac; the 285/40R17 rear 456 size comes from Nitto; the 255/40R18 and 265/40R18 sizes are covered by BFGoodrich; the 295/35R18 rear 550 size comes from Pro-Trac; and the 225/40R18 front F355 size is available from BFGoodrich and Nitto.

Brand choice often comes down to how closely you are trying to match your intended use and visual preference within the correct size. Some sizes offer a broader spread of tread lines and sidewall treatments, while others are far more concentrated. It is wise to compare both front and rear availability together so you do not commit to one axle before making sure the matching staggered partner is covered as well.

In 225/40R18 for a 1998 Ferrari F355, BFGoodrich and Nitto both offer Blackwall radial tires, but their spec details are not identical. BFGoodrich appears in multiple series, with W-rated versions and maximum load figures of 1,235 pounds at 51 psi and 1,389 pounds at 50 psi depending on the tire. Nitto's NT555 G2 in the same size is also W-rated to 168 mph, carries a 1,389-pound maximum load at 50 psi, and fits 7.5 to 9.0-inch rims with an 8.0-inch measuring width reference.

For the buyer, that means the decision is less about basic fit and more about the exact tread line and specification set you want within the correct F355 front size. Since the rear 265/40R18 has a narrower product spread, compare the full front-and-rear combination before settling on a front tire. Keeping both axles in balance matters more on an F355 than making a decision from one size alone.

Rim-width ranges depend on the exact 1998 Ferrari tire size. The 255/45R17 fits 8.0 to 9.5-inch rims, 285/40R17 fits 9.5 to 11.0, 255/40R18 fits 8.5 to 10.0, 225/40R18 fits 7.5 to 9.0, and 265/40R18 fits 9.0 to 10.5. Those ranges cover the core sizes used by the 456, 550 Maranello, and F355 family.

This becomes especially important when a 1998 Ferrari has aftermarket wheels or a wheel from another variant. A tire may share the right diameter and still be wrong for the wheel's actual width, which can affect sidewall shape and overall behavior. Checking the stamped wheel size or measuring the wheel before purchase is the cleanest way to avoid mismatches on staggered Ferrari fitments.

The 1998 Ferrari sizes covered here are modern radial fitments, and none of these products carry a tube-type marking in the size description. That points to tubeless radial use across the available 17-inch and 18-inch Ferrari applications. The fitment families for the 456, 550 Maranello, and F355 all follow that modern late-1990s pattern.

Even so, the wheel itself still matters. If a wheel has been restored, repaired, or replaced, confirm that it is in proper tubeless condition and that the valve stems are correct for the application. On a collector Ferrari, slow leaks are often just as likely to come from aging stems or wheel-sealing issues as from the tire itself, so the full wheel-and-tire assembly deserves attention.

No single original wheel fits every 1998 Ferrari tire size, because the year spans both 17-inch and 18-inch applications as well as different front and rear widths. The 456 family uses 17-inch front and rear tires, while the 550 Maranello and F355 family use staggered 18-inch combinations. Even within the same diameter, the acceptable rim-width range changes significantly from front to rear.

That means original wheels can be reused when they belong to the correct model and axle position, but they are not universal across the entire 1998 Ferrari range. Before mounting a replacement tire, confirm both the wheel diameter and the wheel width at that corner of the car. That is especially important on rear Ferrari fitments, where the tire and wheel package is much wider than the front.

A stored 1998 Ferrari should be kept in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Tire pressures should be maintained, and the car should either be moved periodically or supported in a way that reduces long-term static loading if it will sit for an extended period. These are radial tires, so they generally tolerate storage better than older bias-ply designs, but age and environment still matter.

The practical goal is to prevent cracking, flat spotting, and casing stress while preserving an expensive wheel-and-tire package. Clean the tires with mild soap and water rather than harsh dressings, and avoid leaving the car on a damp surface for months at a time. If the Ferrari is driven only seasonally, a brief inspection and pressure check before and after storage helps catch problems before they become roadside issues.

On a 1998 Ferrari, tire age is usually more important than mileage. Collector and exotic cars often accumulate miles slowly, so a tire can look usable while still aging out internally. A sensible rule is to begin evaluating tires closely around five to seven years of age and to treat around ten years as a serious replacement threshold regardless of tread depth. The DOT date code on the sidewall is the starting point for that timeline.

That approach matters on Ferraris because the cars may spend long periods parked, then return to service at speeds and cornering loads that expose old rubber very quickly. If a tire shows sidewall cracking, hardening, repeated pressure loss, or uneven aging between front and rear, replacement moves from preventive maintenance to priority work. Age-based thinking is the safer standard for a low-use performance car.

Tires on a 1998 Ferrari should be inspected before every drive and again before any longer outing. Check inflation pressure, sidewall condition, tread wear, embedded debris, punctures, and any bulges or impact damage. Because these cars use staggered high-performance fitments, it is also worth watching for uneven wear patterns that may point to alignment or suspension issues rather than a tire defect.

A quick walkaround catches problems that are easy to miss on a car that has been sitting in a garage looking pristine. If the Ferrari has not been driven recently, pay extra attention to valve stems, pressure retention over several days, and the condition of the spare if one is carried. Short inspections done consistently are far more useful than occasional deep checks after a problem has already developed.

A 1998 Ferrari 456 GT belongs to an era when radial construction was standard, and its correct fitment family uses 255/45R17 at the front and 285/40R17 at the rear. That tells you the key originality points are the proper stagger, the proper wheel diameter, and a modern radial profile appropriate to a late-1990s V12 grand tourer. Original-equipment brand details can vary by market and period, so brand should be confirmed through Ferrari literature or marque specialists when absolute historical accuracy matters.

For most restorations, getting the correct front and rear size relationship is the first priority, followed by choosing a sidewall appearance that suits the car's intended presentation. A blackwall look aligns most naturally with the period, while more decorative sidewalls push the car toward a custom aesthetic. If the car will be judged, consult Ferrari club resources and event-specific standards before finalizing the tire choice.

Yes, correct tire fitment matters on a shown 1998 Ferrari because judges and knowledgeable enthusiasts notice size, construction, and sidewall presentation. On a late-1990s Ferrari, the expected foundation is radial construction in the correct staggered sizes for the model. A 456 on F355 sizes, a 17-inch fitment on a 550 Maranello, or a sidewall style that feels out of character for the era can all stand out immediately.

The level of scrutiny depends on the event. A casual cars-and-coffee crowd may focus more on condition, while marque judging can be much stricter about details that affect visual authenticity. If the car is being prepared for concours-level review, verify not just the size code but also the sidewall treatment and overall stance. Ferrari club judging guides and model registries are the best places to confirm event-specific expectations.

In the 255/40R18 front size for a 1998 Ferrari 550 Maranello, BFGoodrich offers both the g-Force Sport Comp 2 and the g-Force Phenom T/A. Both are Blackwall radials fitting 8.5 to 10.0-inch rims, but they differ in speed rating and load figure. The g-Force Sport Comp 2 appears with a 95W specification and a maximum load of 1,521 pounds at 51 psi, while the g-Force Phenom T/A carries a 99Y specification with a maximum load of 1,709 pounds at 50 psi.

That makes the choice a matter of selecting the specification set that best matches how you use and present the car while staying within the correct size. Because both tires keep the same fundamental fitment envelope, the comparison is more refined than simply deciding whether one will fit. It is wise to consider the rear tire pairing at the same time so the full 550 setup remains coherent front to rear.

Yes, the 1998 Ferrari tires covered here are modern radial performance sizes suitable for highway use when they are in good condition, correctly inflated, and matched to the proper model and axle. Speed ratings in this group include W, which is rated to 168 mph, and Y, which is rated to 186-plus mph. Those ceilings are well beyond normal U.S. highway speeds, so in ordinary driving the larger question is usually tire age, pressure, and overall vehicle condition rather than the tire's raw speed symbol.

A late-1990s Ferrari is still a specialized performance car, and roadworthiness depends on the complete chassis package. Suspension bushings, alignment, brakes, and wheel condition all influence how secure the car feels at speed. If the tires are older, recently acquired, or mounted on a car that has been dormant, a careful inspection and road test at modest speed are smarter than assuming a high speed rating alone makes everything ready for travel.

Inflation pressure for a 1998 Ferrari should start with Ferrari's model-specific recommendation, since the 456, 550 Maranello, and F355 all use different tire sizes and front-to-rear weight distributions. Tire pressure figures tied to the tires themselves appear as rated maximum load and pressure values on some products: for example, 255/45R17 reaches 1,653 pounds at 51 psi or 1,874 pounds at 50 psi depending on the tire, 285/40R17 reaches 1,984 pounds at 50 psi, 255/40R18 reaches 1,521 pounds at 51 psi or 1,709 pounds at 50 psi, 225/40R18 reaches 1,235 pounds at 51 psi or 1,389 pounds at 50 psi, and 265/40R18 reaches 1,819 pounds at 50 psi.

Those figures are not the same thing as the pressure you should automatically run on the car. They describe the tire's rated capacity ceiling, not Ferrari's ideal cold inflation target for ride, wear, and handling balance. Use the owner's manual or factory pressure placard first, then confirm that the chosen tire's specifications support that setting. Never transfer a pressure from one Ferrari model or size to another just because the cars share the same year.

Before a longer drive in a 1998 Ferrari, inspect each tire for cracking, cuts, bulges, punctures, uneven tread wear, and proper cold inflation. Make sure the front and rear sizes match the model's intended stagger, and check that each tire is seated on an appropriate wheel width. If the car has been sitting, verify that none of the tires have developed a slow leak or vibration-causing flat spot.

Tires are only one part of the pre-drive check on an older exotic. Look at brake feel, fluid levels, wheel fastener security, suspension response, and the condition of the spare or mobility plan you carry with the car. A 1998 Ferrari can cover distance very well when prepared correctly, but a small tire issue or pressure loss becomes more serious when combined with the speeds and loads these cars are capable of carrying.
