2018 Ferrari Tire Fitment Guide

2018 Ferrari vehicles use eight sizes across seven models: 245/35R20, 305/30R20, 275/35R20, 315/35R20, 245/40R19, 285/35R20, 285/40R19, and 295/35R20. The 488 GTB and 488 Spider use 245/35R20 front and 305/30R20 rear; the 812 Superfast uses 275/35R20 front and 315/35R20 rear; the California T uses either 245/40R19 and 285/40R19 or 245/35R20 and 285/35R20; the GTC4Lusso and GTC4Lusso T use 245/35R20 front and 295/35R20 rear; and the Portofino uses 245/35R20 front and 285/35R20 rear.

Most of the range uses 20-inch wheels, but the California T also appears with a 19-inch stagger, so year and make alone are not enough. If your Ferrari has mixed front and rear sizes, match the stagger exactly and confirm the wheel diameter before comparing brands or sidewall styles. Rim-width guidance is published for several front and rear sizes, including 245/35R20 and 245/40R19 at 8.0 to 9.5 inches, 275/35R20 at 9.0 to 11.0 inches, and 285/35R20 or 285/40R19 at 9.5 to 11.0 inches.

On a 2018 Ferrari, 245/35R20 is a metric radial size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. This size appears as a front fitment on the 488 GTB, 488 Spider, GTC4Lusso, GTC4Lusso T, Portofino, and some California T applications, so it is one of the most widely shared front sizes in the 2018 range.

That broad use does not make 245/35R20 a universal Ferrari tire, because the matching rear size changes from model to model. A 488 pair uses a much wider 305/30R20 rear, while a Portofino uses 285/35R20 and a GTC4Lusso uses 295/35R20. If you are replacing only the fronts, verify that your car’s wheel diameter is 20 inches and check whether the tire you want carries the speed symbol and sidewall style that suit your intended use.

No. 2018 Ferrari models do not use one common size across the lineup. Even though 245/35R20 is shared by six models, the rear sizes split into 305/30R20 for the 488 GTB and 488 Spider, 295/35R20 for the GTC4Lusso and GTC4Lusso T, 285/35R20 for the Portofino and some California T applications, and 315/35R20 for the 812 Superfast. The California T also stands apart by appearing with either a 19-inch or 20-inch setup.

That means model identification comes before any brand comparison. Ferrari’s 2018 range includes a mid-engine supercar, a front-engine V12 flagship, open grand tourers, and a four-seat shooting brake, and the tire packages reflect those different missions. Check the model name and wheel diameter on the car first, then verify whether you are replacing a front, a rear, or a full staggered set so the sizes stay matched to the vehicle’s original fitment pattern.

2018 Ferrari tire options include mostly Blackwall products, with select sizes also offering RWL or Redline sidewall treatments. 245/35R20, 275/35R20, 245/40R19, 285/40R19, and 295/35R20 stay in Blackwall form, while 305/30R20 and 285/35R20 add white-letter or redline choices through Pro-Trac. That means sidewall appearance depends on the exact size, not just the year and make.

For a modern Ferrari, Blackwall is usually the most natural visual match because it keeps attention on the wheel design and bodywork rather than the sidewall. RWL and Redline choices create a custom look that some owners may want, but they shift the presentation away from the understated late-model exotic style Ferrari typically carried in 2018. If appearance matters as much as fitment, choose the tire only after confirming which sidewall treatments exist in your exact front and rear sizes.

BFGoodrich, Nitto, and Pro-Trac all cover portions of the 2018 Ferrari size range. BFGoodrich appears in 245/35R20, 275/35R20, 245/40R19, and 285/35R20, Nitto appears in 245/35R20, 305/30R20, 275/35R20, 315/35R20, 285/35R20, and 295/35R20, and Pro-Trac appears in 305/30R20, 275/35R20, and 285/35R20. Brand coverage is strongest in the shared mainstream performance sizes and narrower in the more specialized Ferrari-specific rear fitments.

The practical effect is that some models have more room to compare series and sidewall looks than others. A California T or Portofino owner may see more overlap in available brands, while an 812 Superfast rear or GTC4Lusso rear fitment is naturally more limited. Start by identifying the exact size at each axle, then compare brand choices within that size rather than assuming the same options carry across the entire 2018 Ferrari lineup.

For 2018 Ferrari applications where both appear, BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 share the same basic modern radial format but differ in coverage and some published details. In 245/35R20, both appear in Blackwall form with W speed ratings, while BFGoodrich publishes an 8.0 to 9.5 inch rim-width range and weights around 29 pounds, and Nitto carries a similar weight at 28.21 pounds. In 285/35R20, BFGoodrich and Nitto again overlap, with BFGoodrich publishing a 9.5 to 11.0 inch rim-width range and W or Y speed-rated variations in that family.

That comparison matters most when you are choosing among tires that already fit the same Ferrari size correctly. One buyer may care more about matching a certain sidewall look or published rim-width window, while another may focus on whether the available tire in that size carries a W or Y speed symbol. Compare the exact front and rear size separately, because the same two brands do not overlap evenly across every 2018 Ferrari application.

Published rim-width guidance for 2018 Ferrari sizes varies by tire size. 245/35R20 and 245/40R19 are paired with 8.0 to 9.5 inch rim ranges, 275/35R20 is paired with 9.0 to 11.0 inches, and 285/35R20 plus 285/40R19 are paired with 9.5 to 11.0 inches on the products that state it. Every size does not carry a published rim-width figure, so the wheel-and-tire relationship still needs to be checked size by size.

That matters because Ferrari uses staggered setups with very different front and rear section widths, and a tire that fits the front wheel correctly may be completely wrong for the rear wheel. Use the exact size mounted on each axle as your starting point, then compare the tire manufacturer’s approved rim-width range against the wheel actually on the car. This is especially important on cars that may have aftermarket wheels or multiple factory wheel packages.

2018 Ferrari tires in these sizes are modern radial products, and the fitments here are not tube-type applications. One 285/35R20 product carries an explicit TL tubeless marking, while the rest use modern performance sizing conventions without tube-type markings. That points buyers toward tubeless use rather than inner-tube installation for these Ferrari applications.

The key step is to verify the exact marking on the tire you choose and make sure the wheel is in proper condition for tubeless service. On late-model exotic wheels, valve-stem condition, bead-seat cleanliness, and wheel integrity matter just as much as the tire itself. If a car has been stored for long periods or has aftermarket wheels, inspect the wheels closely before mounting new tires and avoid assuming every 20-inch wheel is equivalent.

No single set of original 2018 Ferrari wheels works with all sizes across the model range, because wheel diameter and stagger change by model. Most applications use 20-inch wheels, but the California T also appears with a 19-inch front-and-rear stagger. Even among the 20-inch cars, the rear widths differ substantially, so a 488 rear tire, an 812 rear tire, and a GTC4Lusso rear tire are not interchangeable just because they share the same diameter.

Original wheels can usually remain in service when you stay with the exact front and rear sizes intended for that specific Ferrari model and wheel package. The right approach is to confirm the wheel diameter first, then verify that the tire’s approved rim-width range matches the actual wheel. That check becomes especially important if the car has replacement wheels, optional wheel packages, or a history that makes the original equipment uncertain.

A 2018 Ferrari should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber. Keep the tires clean, maintain proper inflation, and avoid letting the car sit for long periods in one exact position if possible. Modern radials generally tolerate storage better than older bias-ply designs, but low-profile performance tires can still develop temporary flat-spotting and sidewall aging if neglected.

Move the Ferrari periodically or support it appropriately if it will sit for an extended season, especially if the car carries wide rear tires with a large contact patch. A breathable indoor cover helps the body, but tire care still depends on environment and pressure stability. Before returning the car to regular use, inspect all four tires for cracking, hardening, punctures, and pressure loss rather than assuming low mileage means the tires are still road-ready.

Tires on a 2018 Ferrari should be evaluated by age as much as by tread wear. For collector and low-mileage use, a practical rule is to inspect closely once tires reach the five- to seven-year range and to treat around ten years as a serious replacement threshold, regardless of remaining tread. The DOT date code on the sidewall tells you when the tire was built, and that age matters even on cars that spend much of their time indoors.

A Ferrari that sees occasional weekend use can wear out tires chemically long before it wears them out mechanically. Heat cycles, storage conditions, and underuse all matter, especially on wide low-profile rear fitments. If the car still has older tires that look presentable at a glance, check the date codes and inspect the inner sidewalls as carefully as the outer ones. Aging performance tires can lose confidence and consistency well before they look obviously worn.

Tires on a 2018 Ferrari deserve a quick inspection before every drive and a more thorough inspection before any longer outing. Check inflation, tread depth, shoulder wear, cuts, bulges, and any signs of sidewall cracking, and make sure the valve stems are in good condition. On a staggered Ferrari setup, compare front and rear condition separately because the wider rear tires often age and wear differently from the fronts.

That routine matters because performance cars can mask tire problems until speeds rise or road conditions worsen. A quick driveway check takes only a few minutes and can catch a puncture, pressure drop, or developing sidewall issue before it becomes a ruined trip or a damaged wheel. If the car has been parked for weeks, pay special attention to temporary flat-spotting during the first miles and recheck pressures once the tires have stabilized.

Yes, the 2018 Ferrari tire sizes here are covered by modern radial products suitable for highway use when they are the correct size, in sound condition, and inflated properly. Speed ratings in these sizes include W, which carries a ceiling of 168 mph, and Y, which carries a ceiling of 186 mph. Those ratings are already beyond normal U.S. highway use, and in real driving the car’s condition, alignment, braking system, suspension health, and tire age matter as much as the speed symbol itself.

The practical point is to match the tire to the exact Ferrari model and axle position, then verify that all four tires are healthy enough for sustained road use. A modern exotic with old or damaged tires is less confidence-inspiring than one on fresh, correctly matched rubber, even if the tread still looks deep. For longer interstate driving, focus on age, pressure stability, and uniformity across the axle pair rather than chasing the highest speed symbol alone.

Inflation pressure for a 2018 Ferrari should follow the vehicle’s factory recommendation first, because the correct cold pressure depends on the specific model, axle, and wheel package. Tire load-and-pressure information appears on some of these sizes: 245/35R20 carries up to 1521 pounds at 50 psi, 245/40R19 carries up to 1653 pounds at 50 psi, and 275/35R20 carries up to 1874 pounds at 50 psi on the products that publish that figure. Those numbers are tire capacity references, not a universal Ferrari setting.

Use the door-jamb label, owner’s manual, or Ferrari service information for the starting cold pressure, then compare that with the tire manufacturer’s published limits for the exact tire you choose. Do not transfer a pressure figure from one Ferrari size to another, and do not assume a front-engine grand tourer wants the same pressures as a mid-engine 488. Recheck pressures when ambient temperatures change sharply, since low-profile performance tires are sensitive to even small pressure swings.

Before a longer drive in a 2018 Ferrari, inspect all four tires for cracking, punctures, cuts, bulges, embedded debris, uneven wear, and cold inflation pressure. Confirm that the front and rear sizes still match the car’s intended stagger, and inspect the spare or mobility kit if the car has one. Because these are tubeless modern radial fitments, valve stems, bead sealing, and wheel condition deserve the same attention as tread and sidewalls.

Tires are only one part of a sensible pre-drive check on a modern Ferrari that may spend much of its life parked. Also look over brakes, fluids, battery condition, and any warning lights before committing to a long trip. If the car has sat for a while, start with a shorter local drive to feel for vibration, pull, or flat-spotting, then recheck pressures and temperature consistency before heading out for sustained highway mileage.
