The 2018 Maserati Ghibli blends Italian luxury-sedan styling with a distinctly performance-oriented stance, and tire fitment is a big part of how that character comes through on the road. This is a modern Ghibli, so the tire decision is less about vintage-style construction and more about matching the exact front and rear setup to the wheel package on the car. The 2018 Maserati Ghibli uses staggered radial sizes across 19-inch, 20-inch, and 21-inch combinations, with narrower front sizes and wider rear sizes. Available choices include blackwall, redline, and raised white letter treatments in select sizes. The key is confirming wheel diameter and whether the car needs front or rear fitment before comparing brands and tire series.
Which Tire Size Is Right for The 2018 Maserati Ghibli
The 2018 Maserati Ghibli uses six primary tire sizes, and the correct choice depends first on whether you are replacing a front or rear tire and which wheel diameter is on the car. All of these are radial sizes, but they span 19-inch, 20-inch, and 21-inch rims in a staggered setup, so confirming the exact wheel and axle position is the first step before comparing tire series, sidewall style, or brand.
245/35R21 is a metric radial size where 245 identifies section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 21 is the rim diameter in inches. On the 2018 Maserati Ghibli, this size serves as a front fitment in the 21-inch staggered setup and maintains the modern low-profile look expected from a large-diameter wheel package. It sits alongside wider rear sizing rather than functioning as a stand-alone all-around fitment. This is the size to evaluate when the Ghibli has 21-inch front wheels and you want to preserve the intended front-to-rear relationship.
245/40R20 is a metric radial size with a 245-millimeter section width, a 40-series profile, and a 20-inch rim diameter. For the 2018 Maserati Ghibli, it is a front tire size used with the 20-inch staggered arrangement, giving buyers a direct front-axle size with meaningful product choice. Available options include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter sidewall treatments represented in this size. It is the right size to compare when replacing front tires on a Ghibli equipped with 20-inch wheels and a wider rear companion size.
245/45R19 follows the same metric radial format, with 245 as the nominal section width in millimeters, 45 as the aspect ratio, and 19 as the wheel diameter. On the 2018 Maserati Ghibli, this is the front tire size used with the 19-inch staggered setup, making it the front-side counterpart to a wider 19-inch rear tire. BFGoodrich and Nitto options are available in this size, mainly in blackwall sport-oriented radial lines. This size matters when the car is riding on 19-inch wheels and the goal is keeping the proper front fitment rather than choosing by width alone.
275/40R19 is a metric radial size with a wider 275-millimeter section width, a 40-series profile, and a 19-inch rim diameter. On the 2018 Maserati Ghibli, this size is used at the rear in the 19-inch staggered configuration, pairing with the narrower 245/45R19 front tire. Product choices in this size include BFGoodrich and Nitto, with blackwall sidewalls and several g-Force and NT555 G2 series options. This is the size to focus on when replacing rear tires on a 19-inch-equipped Ghibli and maintaining the proper staggered front-to-rear setup.
285/30R21 is a metric radial size where 285 denotes section width in millimeters, 30 is the low-profile aspect ratio, and 21 is the required rim diameter. For the 2018 Maserati Ghibli, this is the rear fitment used with the 21-inch wheel package, complementing the 245/35R21 front size in a wide staggered arrangement. Its role is specifically rear-axle fitment on that wheel diameter, not a general replacement for the other rear sizes. This is the size to confirm when the car carries 21-inch rear wheels and the goal is preserving the intended stance and size relationship.
285/35R20 is a metric radial size with a 285-millimeter section width, a 35-series profile, and a 20-inch rim diameter. On the 2018 Maserati Ghibli, it serves as the rear tire in the 20-inch staggered setup and offers one of the broadest product selections among the applicable sizes. BFGoodrich, Nitto, and Pro-Trac options appear here, with blackwall, redline, and raised white letter treatments available across different series. This is the rear size to compare when the car is equipped with 20-inch wheels and you want to match the proper staggered fitment rather than mix rear diameters.
Sub-model fitment on the 2018 Maserati Ghibli is driven more by front-versus-rear position and wheel diameter than by a single all-around size. Checking the exact sub-model and axle location matters because the covered configurations share staggered radial sizing with different front and rear dimensions.

2018 Maserati Ghibli Base Front
The 2018 Maserati Ghibli Base Front uses the narrower front tire sizes within the 19-inch, 20-inch, or 21-inch wheel packages. Tire selection here starts with confirming wheel diameter, then comparing the available radial options that suit the front axle setup.
The 2018 Maserati Ghibli Base Rear uses the wider rear tire sizes that complete the staggered fitment. Choosing for this position means matching the correct rear size to the wheel diameter already on the car and avoiding front-size substitutions.
The 2018 Maserati Ghibli S Front follows the same front-size pattern used across the covered front applications. The practical step is identifying whether the car has 19-inch, 20-inch, or 21-inch front wheels before narrowing the choice by brand, series, or sidewall style.
The 2018 Maserati Ghibli S Q4 Front uses the same group of front radial sizes found on the other front-position configurations. Wheel diameter is the deciding factor first, after which tire choice becomes a matter of selecting the right product within that front size.
The 2018 Maserati Ghibli S Q4 Rear uses the wider rear sizes associated with the staggered 19-inch, 20-inch, or 21-inch combinations. That makes rear tire replacement a wheel-diameter and axle-position decision before any comparison of tire series or sidewall treatment.
The 2018 Maserati Ghibli S Rear shares the same rear fitment pattern as the other covered rear applications, with wider tires than the front. The right choice comes from matching the exact rear wheel diameter and keeping the intended staggered relationship intact.
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.

Tire Size & Fitment
What tire size fits a 2018 Maserati Ghibli?
The 2018 Maserati Ghibli uses staggered radial tire sizes rather than one universal size. Front sizes are 245/45R19, 245/40R20, and 245/35R21, while rear sizes are 275/40R19, 285/35R20, and 285/30R21.
The right choice depends on two things before anything else: whether the tire is for the front or rear axle and what wheel diameter is on the car. A front 245 size and a rear 275 or 285 size are not interchangeable just because they belong to the same model year, so checking the mounted wheel and current tire sidewall is the safest starting point.
What size rim does a 2018 Maserati Ghibli use?
A 2018 Maserati Ghibli uses 19-inch, 20-inch, or 21-inch rims, depending on the wheel package on the car. The applicable tire sizes match those diameters exactly, so each tire must stay on its corresponding 19, 20, or 21-inch wheel.
That makes rim-diameter confirmation the first fitment check before comparing brands or tread styles. Even when the overall tire diameters are close across the different packages, a 19-inch tire cannot be mounted on a 20-inch wheel, and a 20-inch tire cannot be mounted on a 21-inch wheel, so the wheel itself has to be verified first.
Why does the 2018 Maserati Ghibli have more than one tire size?
The 2018 Maserati Ghibli has more than one tire size because it uses staggered front and rear fitment across multiple wheel-diameter packages. The front axle uses 245-width tires, while the rear axle uses wider 275-width or 285-width tires depending on whether the car has 19-inch, 20-inch, or 21-inch wheels.
That means tire selection is tied to the car's actual wheel setup, not just the model name. A buyer should confirm the axle position, read the current tire size, and verify the wheel diameter before replacement. This prevents mixing front and rear sizes or choosing the correct width on the wrong rim diameter.
Choosing the Right Tire
What should I consider when choosing a 2018 Maserati Ghibli tire?
Start with the exact size, axle position, and wheel diameter already on the car. The 2018 Maserati Ghibli uses radial tires in staggered front and rear combinations, so the first decision is not brand but whether you need the correct front or rear size for a 19-inch, 20-inch, or 21-inch setup.
After size is confirmed, compare construction details such as rim-width specification where shown, load information where available, sidewall style, and tire series. A sport-oriented blackwall may suit a modern performance look, while redline or raised white letter options in certain 20-inch sizes may appeal to buyers who want a more customized presentation.
What sidewall styles are available for 2018 Maserati Ghibli tires?
Sidewall style depends on the exact size. Blackwall options are available across the supported 19-inch and 20-inch sizes with product choices from BFGoodrich and Nitto, while 20-inch sizes also include Pro-Trac Street Pro III options with raised white letter and redline sidewall treatments.
That makes sidewall choice part of the appearance decision once fitment is settled. A buyer replacing 245/40R20 or 285/35R20 has more visible style variation than someone replacing 19-inch sizes, so it helps to decide whether the goal is a clean modern blackwall look or a more assertive customized sidewall presentation.
What brands offer tires for the 2018 Maserati Ghibli?
Applicable product options for the 2018 Maserati Ghibli include BFGoodrich, Nitto, and Pro-Trac, depending on the tire size. BFGoodrich appears across several supported 19-inch and 20-inch sizes, Nitto is also represented in both front and rear sizes, and Pro-Trac appears in select 20-inch fitments.
Brand comparison should come after confirming the exact front or rear size needed. Once that is settled, buyers can compare tire series, sidewall treatment, and any stated rim-width or load details within that size rather than assuming every brand offers the same fitment across all six Ghibli tire sizes.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Maserati Ghibli?
A 2018 Maserati Ghibli is a modern luxury performance sedan, so a period-style approach usually means preserving the car's intended staggered radial layout and wheel-diameter package rather than moving toward vintage-style construction. The correct starting point is keeping the proper front and rear metric radial sizes for the 19-inch, 20-inch, or 21-inch setup already on the car.
Appearance then comes from the product style within that fitment. Blackwall choices keep the presentation closest to a contemporary factory-inspired look, while redline or raised white letter options in certain 20-inch sizes create a more personalized visual statement. For exact originality questions, vehicle-specific documentation and marque guidance remain the best references.
How does tire construction affect the appearance of a restored 2018 Maserati Ghibli?
On a 2018 Maserati Ghibli, construction is straightforward because the applicable primary fitments are all radial. That means the visual difference comes less from bias-ply-versus-radial decisions and more from preserving the correct low-profile metric sizing, front-to-rear stagger, and the overall proportion created by 19-inch, 20-inch, or 21-inch wheel packages.
The strongest appearance changes come from sidewall treatment and maintaining the intended wheel-to-tire relationship. A blackwall keeps the look understated and contemporary, while redline or raised white letter options on certain 20-inch sizes change the visual tone more noticeably. Keeping the proper front and rear widths is just as important to the car's stance as the sidewall style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Maserati Ghibli?
Yes. If a 2018 Maserati Ghibli has aftermarket wheels, suspension changes, lowered ride height, or body modifications, tire fitment can change even when the tire size is one of the standard front or rear sizes for the model. Wheel diameter, wheel width, and available clearance all matter once the factory setup has been altered.
That is especially important on a staggered car with low-profile tires. A size that works on a stock wheel package may need closer checking if offset or suspension travel has changed, so the smart approach is to confirm wheel dimensions and inspect steering, fender, and inner-clearance areas before committing to a replacement tire.
What should I inspect before driving a 2018 Maserati Ghibli on new tires?
Before regular road use, inspect the tire size, axle position, wheel diameter match, and inflation condition, then look over the tires for any visible cuts, bulges, or mounting issues. It also helps to confirm that the front tires are mounted on the front axle and the wider rear tires are mounted on the rear axle.
A quick walk-around should also include checking for clearance at full steering lock, especially if the car has non-stock wheels or suspension changes. After the first few drives, recheck air pressure and watch for uneven wear or contact marks. Catching a fitment or pressure issue early is much easier than troubleshooting it after extended use.
How often should tires on a 2018 Maserati Ghibli be inspected?
Tires on a 2018 Maserati Ghibli should be inspected regularly, especially because the car uses low-profile staggered fitments that can show wear patterns differently front to rear. A visual check before longer drives and a more careful inspection at routine service intervals is a sensible habit.
Look for tread wear, air loss, sidewall cracking, punctures, and any signs of contact with suspension or bodywork. Cars that sit for long periods deserve extra attention, since age and storage conditions matter as much as mileage. Keeping inflation consistent and watching each axle separately helps preserve the intended handling balance of the staggered setup.
