Ferrari F40 Tires

Ferrari F40 uses three listed tire sizes across the 1990, 1991, and 1992 model years: 235/45R17, 245/40R17, and 335/35R17. All three are metric radial sizes designed for 17-inch rims, and each appears within the same production years rather than being tied to a simple early-versus-late model change.

That means the correct choice depends on the specific wheel position and the exact setup on the car, not just the year on the title. Start by reading the size on the existing tire, then confirm the wheel width and compare it to the intended fitment range before replacing anything on a Ferrari F40.

On a Ferrari F40, 235/45R17 means the tire is 235 millimeters wide, has a sidewall height equal to 45 percent of that width, uses radial construction, and fits a 17-inch wheel. The same metric radial logic applies to the other listed Ferrari F40 sizes as well, with the first number showing width, the middle number showing profile, and the final number showing rim diameter.

That decoding matters because a small change in width or aspect ratio can alter clearance, stance, and overall balance on a high-performance car like the Ferrari F40. Treat the size molded on the car now as the starting point, then verify the wheel and position before deciding that another listed size is interchangeable.

A 1990 Ferrari F40 has 3 tire sizes listed because the model uses more than one fitment within the same production year: 235/45R17, 245/40R17, and 335/35R17. The split is not a wheel-diameter change, since all of those sizes fit 17-inch rims, so the difference comes down to configuration rather than a year-based wheel change.

On a Ferrari F40, that makes it important to identify the specific setup on the car rather than relying on the model year alone. Check the tire size currently fitted, confirm the wheel width, and keep front and rear fitment logic in mind before selecting replacements for any 1990 Ferrari F40.

A 1991 Ferrari F40 can be associated with 235/45R17, 245/40R17, and 335/35R17, all on 17-inch rims. Since those sizes overlap within the same year, the right answer comes from the actual wheel position, wheel width, and the size already fitted to the car rather than from the year alone.

Begin with the sidewall marking on the tire currently installed, then compare the wheel width to the tire's intended rim-width range. That approach is especially important on a Ferrari F40 because a mismatched width or profile can upset the car's appearance and handling balance even when the rim diameter is correct.

Ferrari F40 tires in the listed sizes are available with Blackwall sidewalls. That sidewall style is consistent across the available 235/45R17, 245/40R17, and 335/35R17 products, so the visual choice here is straightforward compared with many earlier collector cars that offered wide whitewall or other period styles.

For a Ferrari F40, the practical selection question is less about sidewall appearance and more about choosing the right width, profile, and tire series for the car's use. If the goal is to preserve the clean late-1980s and early-1990s supercar look, Blackwall is the style represented across the available fitments.

Ferrari F40 tires in the listed sizes are available from BFGoodrich, Nitto, and Michelin. BFGoodrich appears in both 235/45R17 and 245/40R17, Nitto appears in 235/45R17, and Michelin appears in 335/35R17, which gives the Ferrari F40 a mix of brand options depending on the exact size needed.

Because brand choice changes with size, start with correct fitment first and brand second. Once the proper Ferrari F40 size is confirmed, compare the available series within that size so the tire's intended character aligns with how the car is driven and presented.

Ferrari F40 fitments are represented by several radial performance series, including g-Force Sport Comp 2, g-Force Comp 2 AS, Nitto NT555 G2, Michelin Pilot Sport PS2, and g-Force Phenom T/A. Those series differ by manufacturer line and intended performance character, even though they share the same basic role as modern radial tires for 17-inch Ferrari F40 wheel sizes.

For a Ferrari F40 owner, the useful comparison is within the correct size rather than across the full page. Once the size is settled, look at each series as a separate approach to road performance, then keep the car's intended use in mind so the tire choice supports the way the Ferrari F40 will actually be driven.

A Ferrari F40 should be stored on clean, properly inflated tires in a cool, dry, dark environment away from direct sunlight, ozone sources, and major temperature swings. If the car will sit for an extended period, keeping weight distribution stable and moving the car occasionally can help reduce flat-spotting and stress on the tires.

Because Ferrari F40 uses low-profile performance radials, long idle periods can affect ride quality and shape even when tread wear is minimal. Use storage practices that protect both the tire carcass and the wheel finish, and check inflation pressures before the car is returned to regular road use.

Tires on a Ferrari F40 should be visually inspected before every drive and examined more closely at regular service intervals. Look for cracking, bulges, punctures, uneven wear, impact damage, and any sign that the tire is aging differently from its mate on the same axle.

That routine matters on a Ferrari F40 because high performance and limited annual mileage can hide problems until the car is driven hard. A careful inspection habit helps catch age-related issues, alignment problems, or wheel-width mismatches before they become expensive or dangerous.

Tires on a Ferrari F40 should be replaced when age, cracking, hardening, structural damage, or repeated loss of air shows that the tire has deteriorated, even if tread depth still appears usable. Collector cars often wear out tires by time and condition rather than by mileage, especially when they spend long periods parked.

A Ferrari F40 rewards fresh, properly matched tires more than a low-mileage but aging set. If the car's tires feel hard, show sidewall checking, or have an uncertain service history, replacement is usually the more sensible path than trying to stretch additional years out of them.

Ferrari F40 is represented here by three size families used across 1990 through 1992: 235/45R17, 245/40R17, and 335/35R17, all on 17-inch rims. The available products are modern radial tires from BFGoodrich, Nitto, and Michelin, so the key original-fitment reference points here are size and overall specification rather than a single universal tire listed for every Ferrari F40.

For an authenticity-minded Ferrari F40 owner, matching the car's correct size arrangement is the first priority. If the goal is concours-level accuracy, compare the car against factory literature, period photographs, and Ferrari marque expertise so the selected tire aligns with the exact configuration being restored.

Correct tire fitment can absolutely affect how a Ferrari F40 is viewed in both judging and the collector market. On a landmark car of this level, the right size, proper staggered setup, appropriate sidewall appearance, and an overall period-consistent presentation all contribute to whether the car looks properly sorted.

Even when modern replacement tires are necessary, keeping the Ferrari F40 in the proper size family preserves proportions and supports credibility. Owners pursuing top-level presentation should cross-check the exact fitment against period references and Ferrari-specific judging standards before finalizing a tire choice.

Ferrari F40 tire options here are all Blackwall, which suits the late-classic supercar character of the model. That appearance is in keeping with the clean, purposeful presentation expected on a Ferrari F40, where decorative sidewall treatments would look out of place next to the car's competition-influenced design language.

For restoration work, the practical aim is to pair Blackwall sidewalls with the correct size arrangement and a balanced front-to-rear appearance. On a Ferrari F40, visual correctness comes from getting the full fitment package right rather than treating sidewall style as a separate cosmetic decision.

These Ferrari F40 tires are modern radial road tires in the listed 17-inch sizes, so they are intended for public-road use when they are the correct size for the car, properly mounted, and in sound condition. Safety depends on more than the printed size alone, because the Ferrari F40 uses multiple widths and profiles that need to match the correct wheel position.

Before road use, make sure the Ferrari F40 has a properly matched set, correct inflation, and no age-related defects or damage. A car with this level of performance should also be checked for alignment, suspension condition, and wheel integrity so the tire can do its job as intended.

Before driving a Ferrari F40, check that each tire matches the intended size, inspect for visible cracking or puncture damage, verify inflation pressure, and confirm that tread wear is even across the axle. On a Ferrari F40, it is also wise to look at wheel condition and make sure there is no sign of rubbing, impact damage, or unusual shoulder wear.

Those checks are especially important when the car has been parked for stretches of time or recently had wheels or tires changed. A brief pre-drive inspection helps ensure the Ferrari F40 feels stable, communicates properly, and is not being asked to perform on compromised rubber.

Appropriate speed for a Ferrari F40 depends on the exact tire fitted, its age, and its present condition rather than on the car's capability alone. Even when a tire carries a high-speed service description, that does not override the need for sound condition, correct sizing, proper inflation, and professional installation on a Ferrari F40.

On any collector-performance car, and especially on a Ferrari F40, the sensible approach is to build speed gradually only after confirming that the tires are fresh, correctly matched, and fully sorted. If there is any doubt about age, storage history, vibration, or sidewall condition, keep speeds conservative until the tires are evaluated.
