The 2019 Maserati Quattroporte sits in the modern grand-touring luxury sedan space, blending Italian performance character with the stance and road presence expected from a flagship four-door. Tire selection on this car is more involved than on a single-size setup because the Quattroporte uses several staggered front and rear radial sizes across 19-, 20-, and 21-inch wheel packages. That makes the real decision less about choosing any tire that looks close and more about matching the exact front or rear fitment, then sorting through available brands, series, and sidewall treatments where offered. For appearance, handling balance, and clearance, wheel size and axle position should be confirmed before moving ahead.
Which Tire Size Is Right for The 2019 Maserati Quattroporte
The 2019 Maserati Quattroporte uses six primary tire sizes, all in radial construction, and they vary by front or rear position as well as by 19-, 20-, or 21-inch wheel package. The first step is confirming both the exact sub-model and the wheel diameter on the car, because the Quattroporte uses staggered fitments and not every size belongs on every axle position.
245/35R21 is a metric radial size: 245 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 21 is the wheel diameter in inches. On the 2019 Maserati Quattroporte, this is a front-fitment size used with a large-diameter wheel package and should be treated as part of a staggered setup rather than a universal four-corner size. Product availability is tied to the exact size, so matching the axle position and wheel diameter matters before comparing tread and sidewall details. This size makes sense when the car is already equipped with the corresponding 21-inch front wheel arrangement.
245/40R20 uses a modern metric radial format, with 245 millimeters of nominal width, a 40-series profile, and a 20-inch rim diameter. On the 2019 Maserati Quattroporte, it serves as a front tire size in a staggered arrangement, so it should be matched to the correct rear companion size rather than selected in isolation. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across series such as g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III. It is the right path when the car carries the 20-inch front wheel setup and the buyer wants both fitment accuracy and meaningful product choice.
285/30R21 is a metric radial size with a 285-millimeter nominal section width, a 30-series aspect ratio, and a 21-inch wheel diameter. On the 2019 Maserati Quattroporte, this is a rear tire size used as part of a staggered fitment, so it belongs behind a matching front setup rather than as a stand-alone substitution. Its short sidewall and wide section place extra importance on using the correct wheel diameter and preserving proper clearance at the rear of the car. This size should be evaluated only when the Quattroporte is already running the corresponding 21-inch rear wheel package.
285/35R20 follows the same modern metric radial format, with 285 millimeters of nominal width, a 35-series profile, and a 20-inch rim diameter. For the 2019 Maserati Quattroporte, it functions as a rear staggered size and should be paired with the proper 20-inch front fitment rather than mixed across wheel packages. Available products include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, raised white letter, and redline presentations in series such as g-Force Comp 2 AS, NT555 G2, and Street Pro III. It is the size to consider when the car uses the 20-inch rear wheel setup and the buyer wants to compare both performance-oriented lines and appearance details.
245/45R19 is a metric radial tire size in which 245 denotes nominal width in millimeters, 45 is the aspect ratio, and 19 is the wheel diameter. On the 2019 Maserati Quattroporte, this size is used at the front on certain staggered 19-inch arrangements, making axle position just as important as wheel diameter. BFGoodrich and Nitto offerings appear in this size, including g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2, all in blackwall form. This size should be selected when the car is equipped with the 19-inch front wheel setup and the goal is to preserve the intended front-to-rear tire relationship.
275/40R19 is a metric radial size with a 275-millimeter nominal section width, a 40-series profile, and a 19-inch rim diameter. On the 2019 Maserati Quattroporte, it serves as a rear size in a staggered 19-inch combination, so it is meant to complement the correct 19-inch front tire rather than replace other rear sizes across the lineup. Available options come from BFGoodrich and Nitto, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2, all with blackwall styling. This is the relevant choice when confirming a 19-inch rear wheel package and comparing road-use priorities within the proper rear fitment.
Sub-model fitment on the 2019 Maserati Quattroporte depends on both axle position and wheel package, so tire choice is not the same across the entire range. Checking the exact front or rear sub-model designation matters first, followed by confirming whether the car is on 19-, 20-, or 21-inch wheels.

2019 Maserati Quattroporte GTS Front
The 2019 Maserati Quattroporte GTS Front uses either a 245/35R21 or 245/40R20 radial front tire, depending on the wheel package on the car. That means the key selection step is confirming whether the GTS has 21-inch or 20-inch front wheels before comparing available tire lines.
The 2019 Maserati Quattroporte GTS Rear uses either 285/30R21 or 285/35R20 radial rear fitment, matched to the corresponding front setup. Rear tire choice should follow the actual wheel diameter already on the car so the staggered relationship stays consistent.
The 2019 Maserati Quattroporte S Front can use 245/45R19, 245/40R20, or 245/35R21 radial tires depending on its wheel package. Tire selection starts by identifying the front wheel diameter, then matching the tire to the rear size that belongs with that same package.
The 2019 Maserati Quattroporte S Q4 Front shares the same three possible front sizes as the S Front, with 19-, 20-, and 21-inch radial configurations. The practical step is confirming the actual wheel setup on the car before narrowing the choice to brand, tire series, or sidewall treatment where available.
The 2019 Maserati Quattroporte S Q4 Rear uses 275/40R19, 285/35R20, or 285/30R21 radial rear fitments depending on the wheel package. Matching the rear tire to the correct front size and wheel diameter is essential before comparing specific product options.
The 2019 Maserati Quattroporte S Rear follows the same rear fitment pattern, using 275/40R19, 285/35R20, or 285/30R21 depending on the package in place. Choosing correctly means confirming the car's actual rear wheel diameter first, then selecting within the proper size family.
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 2019 Maserati Quattroporte?
The 2019 Maserati Quattroporte uses six primary radial sizes: 245/35R21, 245/40R20, 285/30R21, 285/35R20, 245/45R19, and 275/40R19. These are not universal four-corner sizes, because the car uses staggered front and rear fitments and different wheel packages across the Quattroporte range.
The important next step is identifying the exact front or rear position and confirming whether the car has 19-, 20-, or 21-inch wheels. A front size and a rear size may look close in overall diameter, but that does not make them interchangeable on the same axle or across different Quattroporte configurations.
What size rim does a 2019 Maserati Quattroporte use?
The 2019 Maserati Quattroporte uses 19-inch, 20-inch, and 21-inch rim diameters, depending on the specific front or rear setup. Tire sizes in this fitment range are built around those wheel diameters, so the rim size must match the final number in the tire size code.
Confirming wheel diameter should be done before comparing brands or tread designs, especially on a Quattroporte with staggered fitment. A 245 front tire may exist in more than one profile, but a 19-inch tire does not belong on a 20-inch or 21-inch wheel, and the same rule applies at the rear.
Why does the 2019 Maserati Quattroporte have more than one tire size?
The 2019 Maserati Quattroporte has more than one tire size because fitment changes by sub-model, axle position, and wheel package. Front sizes are narrower than rear sizes in the staggered combinations, and the car appears with 19-, 20-, and 21-inch wheel diameters across the covered configurations.
That means tire selection starts with the exact configuration already on the car, not with a single Quattroporte-wide answer. Looking at the wheel diameter and whether the tire is mounted on the front or rear axle will prevent mixing front and rear sizes or selecting a tire intended for a different package.
Choosing the Right Tire
What should I consider when choosing a 2019 Maserati Quattroporte tire?
Start with the correct size for the exact axle position and wheel diameter, because the 2019 Maserati Quattroporte uses staggered radial fitments in 19-, 20-, and 21-inch forms. After that, compare the available tire series, sidewall styling, rim-width compatibility where stated, and any published load figures that apply to the exact size.
A Quattroporte that keeps its original wheel package usually benefits from staying within the intended front and rear size pairing. Selection then becomes a matter of balancing appearance, road use, and product character rather than trying to force one tire size to cover every configuration in the lineup.
What sidewall styles are available for 2019 Maserati Quattroporte tires?
Blackwall is the most common sidewall style offered for 2019 Maserati Quattroporte tire sizes. In the available 20-inch fitments, selected Pro-Trac Street Pro III tires also add raised white letter and redline sidewall treatments, giving the buyer a more customized visual option than a standard blackwall presentation.
Sidewall style does not change the need to match the correct axle size and wheel diameter first. Once fitment is confirmed, the sidewall becomes an appearance decision, and that can matter if the goal is to keep the Quattroporte understated or give it a more performance-oriented visual accent.
What brands offer tires for the 2019 Maserati Quattroporte?
Available Quattroporte tire options in the covered sizes come from BFGoodrich, Nitto, and Pro-Trac. Depending on the exact size, those brands appear in series such as g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, NT555 G2, and Street Pro III.
Brand choice should come after size confirmation, since not every series is offered in every Quattroporte fitment. Once the correct size is established, comparing brand and series options can help narrow the selection by sidewall look, stated rim-width range, and the general character suggested by each tire line.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2019 Maserati Quattroporte?
On the 2019 Maserati Quattroporte, construction is straightforward because the primary fitments are all radial. That means appearance differences come less from bias-ply versus radial decisions and more from profile, wheel diameter, and sidewall presentation within the correct modern tire size.
A Quattroporte kept close to its original visual theme will usually look most cohesive when the installed tire size matches the wheel package actually on the car. Sidewall choices such as blackwall, redline, or raised white letter can noticeably change the car's presentation even when the fitment itself remains correct.
Does correct tire fitment matter for a 2019 Maserati Quattroporte restoration?
Correct tire fitment matters on a 2019 Maserati Quattroporte because wheel diameter, front-to-rear stagger, and tire profile all influence the car's stance and overall presentation. Using the wrong axle size or mixing wheel-package fitments can make the car look visually off even before any driving concerns enter the picture.
For restoration-minded work, the safest starting point is the exact size family that belongs to the wheel package installed on the car. Buyers chasing a highly accurate outcome should also compare their wheel setup to vehicle-specific literature or marque references before changing profiles or sidewall appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Maserati Quattroporte?
Yes, modifications can affect tire fitment on a 2019 Maserati Quattroporte. Aftermarket wheels, offset changes, suspension alterations, or body and fender modifications can all change how a 19-, 20-, or 21-inch tire sits in the wheel opening, even when the basic tire size looks correct on paper.
A modified Quattroporte should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and full suspension travel before selecting replacement tires. That is especially important on staggered setups, where front and rear sizes are already different and tolerances can be tighter than on a square layout.
What should I inspect before driving a 2019 Maserati Quattroporte on new tires?
Before driving a 2019 Maserati Quattroporte on new tires, inspect the wheels for damage, confirm the tire sizes match the correct front and rear positions, and make sure inflation pressure is set appropriately for the tires being installed. A quick look for valve-stem condition and even seating around the bead is also worthwhile.
The first miles are a good time to watch for rubbing, vibration, or any sign that the tire is not matched properly to the wheel package. Rechecking pressure and visually confirming clearance after a short drive can catch issues early, especially on low-profile staggered tire combinations.
How often should tires on a 2019 Maserati Quattroporte be inspected?
Tires on a 2019 Maserati Quattroporte should be inspected regularly, not just when tread looks worn. A routine check should cover pressure, tread condition, uneven wear, cuts, bulges, and sidewall damage, with extra attention paid to the inside shoulder area that can be easier to miss on wide rear tires.
Inspection matters even more on cars that are driven less often, because age and long stationary periods can affect tire condition. Checking the Quattroporte before longer drives and at normal service intervals helps catch air loss or wear patterns that may point to alignment, suspension, or wheel-related issues.
