The 2003 Ferrari 456 M GT belongs to the final years of Ferrari’s refined front-engine V12 grand touring coupe, combining long-distance comfort with the kind of speed and composure expected from a hand-built Italian GT. Tire selection on this car centers on a staggered 17-inch radial setup, with 255/45R17 at the front and 285/40R17 at the rear. That makes the decision less about finding one universal size and more about matching the correct position, construction, and appearance. Available choices include blackwall performance radials as well as redline and raised white letter options in the front size, so wheel fitment and intended presentation both matter.
Which Tire Size Is Right for The 2003 Ferrari 456 M GT
The 2003 Ferrari 456 M GT uses two primary tire sizes, and they are position-specific rather than interchangeable. Both are radial tires for 17-inch wheels, with 255/45R17 used on the front and 285/40R17 on the rear, so the first step is confirming which axle you are replacing and making sure the car still has its correct staggered wheel setup.
255/45R17 is a metric radial size in which 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2003 Ferrari 456 M GT, this is the front tire size and it plays an important role in preserving the car’s intended staggered fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter sidewall treatments. This size deserves careful attention if front-end appearance, steering response, and wheel-width compatibility are all part of the decision.
285/40R17 is a metric radial size where 285 is the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 17 identifies the wheel diameter. On the 2003 Ferrari 456 M GT, this is the rear tire size, giving the car the wider rear footprint that belongs with its staggered layout. The available product choice in this size is a Nitto NT555 G2 blackwall radial, which keeps the selection straightforward but still requires attention to wheel width and rear clearance. This is the size to verify carefully when replacing rear tires or checking whether the car still has its proper wheel setup.
Sub-model fitment on the 2003 Ferrari 456 M GT is straightforward because the covered front and rear positions each use one dedicated size. Checking position still matters, since the car uses a staggered setup and the front and rear tires are not the same.

2003 Ferrari 456 M GT Base Front
The 2003 Ferrari 456 M GT Base Front uses the narrower of the two primary radial sizes on a 17-inch wheel. That makes front-tire selection more about choosing the right brand, sidewall style, and wheel-width compatibility while keeping the staggered layout intact.
The 2003 Ferrari 456 M GT Base Rear uses the wider rear-specific radial size on a 17-inch wheel. Rear replacement should focus on preserving the proper front-to-rear size relationship and confirming that the wheel width and overall setup still match the car’s intended staggered fitment.
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.

Common questions for the 2003 Ferrari 456 M GT usually come down to front-versus-rear sizing, 17-inch wheel fitment, radial tire selection, sidewall appearance, and what to inspect before putting a grand touring Ferrari back on the road.
Tire Size & Fitment
What tire size fits a 2003 Ferrari 456 M GT?
The 2003 Ferrari 456 M GT uses a staggered radial tire setup with 255/45R17 on the front and 285/40R17 on the rear. Both sizes mount on 17-inch wheels, but they serve different positions on the car and should not be treated as one universal fitment.
The key step is identifying whether the replacement is for the front axle or the rear axle. A 456 M GT that has aftermarket wheels or previous tire changes should also be checked carefully so the wheel diameter, wheel width, and front-to-rear tire relationship still match the intended staggered setup.
What size rim does a 2003 Ferrari 456 M GT use?
The primary tire fitment for the 2003 Ferrari 456 M GT uses 17-inch rims. Both the 255/45R17 front tire and the 285/40R17 rear tire are built for a 17-inch wheel diameter, so rim diameter remains consistent even though the tire widths differ front to rear.
Rim diameter is only one part of the fitment picture on this Ferrari. Wheel width still matters, especially with a staggered setup, so a car with replacement wheels should be checked for proper front and rear sizing before selecting tires by size code alone.
Why does the 2003 Ferrari 456 M GT have more than one tire size?
The 2003 Ferrari 456 M GT uses two tire sizes because it has a staggered setup, with a narrower 255/45R17 front tire and a wider 285/40R17 rear tire. That arrangement is typical of performance-oriented grand touring cars that separate front and rear tire duties.
For replacement purposes, that means the first decision is tire position rather than brand or sidewall treatment. Any car that has seen wheel swaps, suspension changes, or previous nonstandard tire replacements deserves a careful check so the staggered fitment has not been altered in a way that affects sizing.
Choosing the Right Tire
What should I consider when choosing a 255/45R17 tire for a 2003 Ferrari 456 M GT?
A 255/45R17 front tire for the 2003 Ferrari 456 M GT should be chosen first by correct size and radial construction, then by the kind of presentation and product character you want. Available options include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter sidewall treatments.
After narrowing the visual style, compare wheel-width compatibility and product details that matter for your intended use. A touring-focused owner may prioritize a clean blackwall appearance, while a buyer looking for a more customized visual statement may lean toward redline or raised white letter styling in the same front fitment.
What sidewall styles are available for 2003 Ferrari 456 M GT tires?
Sidewall choices for the 2003 Ferrari 456 M GT include blackwall, redline, and raised white letter styles, though the variety is concentrated in the 255/45R17 front size. The 285/40R17 rear fitment is available here as a blackwall radial, so sidewall matching deserves attention on a full set.
That means appearance can influence product selection almost as much as brand in the front size. Anyone trying to create a consistent overall look should think about how the rear tire presentation will pair with the front, especially if the goal is a clean factory-inspired look or a more personalized period-style treatment.
What brands offer tires for the 2003 Ferrari 456 M GT?
Tire choices for the 2003 Ferrari 456 M GT include BFGoodrich, Nitto, and Pro-Trac. The broadest brand selection appears in the 255/45R17 front size, while the 285/40R17 rear size is represented here by Nitto, making the rear fitment more focused than the front.
Brand choice should still start with the correct axle position and proper wheel compatibility. After that, compare series, sidewall style, and any product specifications that matter to how the car is used, whether the goal is a restrained blackwall look or a more distinctive front-sidewall presentation.
Restoration & Appearance
Which tire should I choose for a period-style 2003 Ferrari 456 M GT?
A period-style approach for a 2003 Ferrari 456 M GT starts with preserving its staggered 17-inch radial sizing: 255/45R17 in front and 285/40R17 in back. From there, the visual decision leans toward whether you want a restrained blackwall performance look or a more noticeable custom-style front sidewall treatment.
Blackwall radials usually keep the presentation closest to the understated grand touring character many owners prefer. If strict originality matters, the exact sidewall appearance should be checked against marque-specific references and the car’s own history, since a correct size alone does not settle every restoration-detail question.
How does tire construction affect the appearance of a restored 2003 Ferrari 456 M GT?
Tire construction is simpler on the 2003 Ferrari 456 M GT because its primary fitment is already radial front and rear. The appearance difference comes less from choosing between bias-ply and radial, and more from choosing the right size, sidewall treatment, and overall visual balance across the staggered setup.
A blackwall radial keeps the look clean and contemporary to the car’s era, while redline or raised white letter styling changes the visual tone of the front fitment noticeably. For a restoration-minded result, matching the car’s character often matters more than selecting the most attention-grabbing sidewall available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2003 Ferrari 456 M GT?
Yes, modifications can affect tire fitment on a 2003 Ferrari 456 M GT even when the replacement tire sizes appear correct. Aftermarket wheels, altered wheel widths, suspension changes, or body adjustments can change how 255/45R17 front and 285/40R17 rear tires sit within the car’s intended staggered layout.
A modified car should be checked for wheel diameter, wheel width, and clearance at both steering lock and normal ride height before new tires are chosen. That extra step matters because a staggered grand touring Ferrari can be more sensitive to setup changes than a vehicle using one tire size at all four corners.
What should I inspect before driving a 2003 Ferrari 456 M GT on new tires?
Before driving a 2003 Ferrari 456 M GT on new tires, inspect the wheels for damage, confirm that the front and rear sizes are mounted in their proper positions, and verify inflation is set correctly for the installed tires. It also helps to check valve stems, balance, and general suspension condition.
A careful walkaround after installation is worthwhile on any low-use grand touring car. Look for fender or inner-clearance concerns, make sure the steering turns cleanly without contact, and recheck pressure after the first few drives so the new tires settle in without a preventable fitment or maintenance issue.
How should tires on a collector 2003 Ferrari 456 M GT be maintained?
Tires on a collector 2003 Ferrari 456 M GT should be maintained with regular pressure checks, visual inspections for cracking, bulges, cuts, and uneven wear, and periodic attention even if the car is driven sparingly. A low-mileage car can still age its tires significantly through time, storage conditions, and inactivity.
Storage habits make a real difference on a V12 grand tourer that may spend long periods parked. Keep the car away from prolonged heat, direct sunlight, and ozone sources, and inspect the tires before any longer outing so age-related condition issues are caught before they affect road use.
