The 2021 Maserati Quattroporte carries the long-running Italian formula of a full-size luxury sport sedan with genuine performance character, and tire fitment plays a major role in preserving that balance. On this model, tire selection centers on staggered front and rear radial sizes, with 19-, 20-, and 21-inch wheel combinations depending on the exact Quattroporte configuration. That makes the first step identifying whether the car is an S, S Q4, or Trofeo, then confirming front versus rear sizing. From there, the choice becomes one of correct dimensions, wheel compatibility, and the sidewall and tire-series presentation that best suits the car's intended road use.
Which Tire Size Is Right for The 2021 Maserati Quattroporte
The 2021 Maserati Quattroporte uses six primary tire sizes, and the correct choice depends on the exact sub-model, axle position, and wheel diameter. All of the primary fitments are radial, but they span 19-, 20-, and 21-inch rims in a staggered front-and-rear layout. Before choosing a tire, confirm whether the car is an S, S Q4, or Trofeo and verify the wheel diameter already on the vehicle.
245/35R21 is a metric radial size in which 245 identifies the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 21 is the rim diameter in inches. On the 2021 Maserati Quattroporte, this is a front fitment used with 21-inch wheels rather than a universal size across every configuration. Its lower-profile format suits buyers who are matching an existing 21-inch setup. The practical step is confirming that the car's current front wheels are 21-inch rims and that the tire remains paired with the correct rear size for the staggered arrangement.
245/40R20 follows the modern metric radial format, with a 245-millimeter nominal width, a 40-series profile, radial construction, and a 20-inch rim diameter. For the 2021 Maserati Quattroporte, it serves as a front tire size on 20-inch wheel packages. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, raised white letter, and Redline sidewall treatments depending on the tire series. It is the right size to evaluate when the car carries 20-inch front wheels and you want to compare appearance as well as tire-series differences.
245/45R19 uses the same modern metric radial sizing system, with 245 millimeters of nominal section width, a 45-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2021 Maserati Quattroporte, this size appears as a front fitment on certain 19-inch wheel combinations rather than across the entire model range. BFGoodrich and Nitto offerings are available here, primarily in Blackwall performance-oriented series. This size deserves attention when maintaining a 19-inch front setup and when making sure the front tire remains correctly matched to the appropriate rear tire size.
275/40R19 is a metric radial size with a 275-millimeter nominal width, a 40-series profile, radial construction, and a 19-inch rim diameter. For the 2021 Maserati Quattroporte, it is a rear tire size used on 19-inch staggered combinations behind the narrower 245/45R19 front. Product choices in this size include BFGoodrich and Nitto, with Blackwall sidewalls across several g-Force and NT555 G2 series options. It is the correct rear size to evaluate when the car has a 19-inch setup and when preserving the intended front-to-rear stagger is part of the goal.
285/30R21 is a modern metric radial size in which 285 is the nominal section width in millimeters, 30 is the aspect ratio, R indicates radial construction, and 21 identifies the wheel diameter. On the 2021 Maserati Quattroporte, this is a rear fitment for 21-inch staggered wheel combinations, paired with a narrower front tire. Its role is specific to that axle and wheel package, so it should not be treated as a stand-alone replacement choice. Buyers considering this size should first confirm a 21-inch rear wheel and then verify that the companion front size matches the same setup.
285/35R20 uses the metric radial system, combining a 285-millimeter nominal width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2021 Maserati Quattroporte, it serves as a rear fitment on 20-inch staggered combinations and is commonly paired with 245/40R20 at the front. Available products include BFGoodrich, Nitto, and Pro-Trac choices, with Blackwall, raised white letter, and Redline sidewall treatments depending on the series. This is the rear size to examine when the car runs 20-inch wheels and appearance is part of the decision along with correct fitment.
Sub-model fitment on the 2021 Maserati Quattroporte varies by both trim and axle position, so tire selection is not as simple as choosing one size for the whole car. The key is confirming the exact Quattroporte version and then matching the correct front and rear sizes to the wheel diameter already in use.

2021 Maserati Quattroporte S Front
The 2021 Maserati Quattroporte S Front uses three possible front radial sizes tied to 19-, 20-, or 21-inch wheel packages. Tire selection here starts with confirming wheel diameter, then comparing available product lines and sidewall treatments only within that matching front size.
The 2021 Maserati Quattroporte S Q4 Front follows the same front-fitment pattern, with three radial sizes across 19-, 20-, and 21-inch setups. That means the right choice depends on the wheel package already on the car, not simply the Quattroporte name alone.
The 2021 Maserati Quattroporte S Q4 Rear uses wider rear radial sizes that correspond to the 19-, 20-, or 21-inch staggered combinations. Rear tire selection should stay tied to the existing wheel diameter and matched to the correct front size so the staggered setup remains consistent.
The 2021 Maserati Quattroporte S Rear shares the same rear-fitment pattern as the S Q4, using three wider radial sizes depending on wheel diameter. The important step is choosing the rear tire that belongs to the car's current 19-, 20-, or 21-inch setup rather than mixing sizes across packages.
The 2021 Maserati Quattroporte Trofeo Front uses two front radial sizes, each tied to either a 20-inch or 21-inch wheel package. Tire selection is therefore more straightforward than on the S models, but wheel diameter still needs to be confirmed before comparing available tires.
The 2021 Maserati Quattroporte Trofeo Rear uses two rear radial sizes that correspond to the Trofeo's 20-inch or 21-inch staggered wheel combinations. The practical goal is matching the rear size to the existing wheel package and keeping it properly paired with the correct Trofeo front 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.

The FAQs below focus on those decisions and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2021 Maserati Quattroporte?
The 2021 Maserati Quattroporte uses staggered radial tire sizes, with front fitments of 245/45R19, 245/40R20, or 245/35R21 and rear fitments of 275/40R19, 285/35R20, or 285/30R21. The exact combination depends on whether the car is an S, S Q4, or Trofeo and on which wheel package the car carries.
The main fitment job is matching the tire size to both the sub-model and the axle position. A front size should stay with its corresponding rear size, and the wheel diameter on the car should be confirmed before replacing anything, especially on vehicles that may have seen wheel changes since new.
What size rim does a 2021 Maserati Quattroporte use?
The 2021 Maserati Quattroporte uses 19-inch, 20-inch, and 21-inch rims depending on the specific tire package. Front and rear tire sizes are tied to those wheel diameters, so the rim size is part of the fitment, not a separate detail that can be overlooked.
Checking the wheel diameter is the first step before choosing replacement tires. On a staggered setup, the front and rear wheels also carry different tire widths, so the safest approach is to read the size on each tire and confirm that the wheel package on the car still matches the intended Quattroporte configuration.
Why does the 2021 Maserati Quattroporte have more than one tire size?
More than one tire size appears on the 2021 Maserati Quattroporte because different sub-models and wheel packages use different staggered front-and-rear combinations. The S and S Q4 can be found with 19-, 20-, or 21-inch setups, while the Trofeo uses 20- or 21-inch combinations with separate front and rear sizes.
That means the correct tire is determined by the exact version of the car and the wheels actually installed on it. Rather than choosing by model name alone, confirm sub-model, axle position, and current rim diameter so the replacement tire matches the Quattroporte's existing setup.
Choosing the Right Tire
What should I consider when choosing a 2021 Maserati Quattroporte tire?
Start with the correct front or rear size for the exact 2021 Maserati Quattroporte sub-model, then confirm the wheel diameter already on the car. All primary fitments are radial, so the decision usually comes down to matching the proper staggered size combination and choosing among the available tire series in that size.
After size is confirmed, compare sidewall style, rim-width compatibility where stated, and any visible differences in load capacity or tire weight that matter to your use. A Quattroporte kept close to its original presentation may call for a different visual choice than one focused mainly on contemporary road driving.
What sidewall styles are available for 2021 Maserati Quattroporte tires?
Sidewall style depends on tire size. Blackwall choices are available in multiple 19- and 20-inch Quattroporte fitments, while some 20-inch sizes also offer raised white letter and Redline sidewalls through Pro-Trac Street Pro III tires.
That makes appearance part of the buying decision, especially on the 20-inch front and rear sizes where more visual variety is available. The practical step is to choose the correct size first, then decide whether a cleaner Blackwall look or a more distinctive sidewall treatment better suits the car.
What brands offer tires for the 2021 Maserati Quattroporte?
Available 2021 Maserati Quattroporte tire options include BFGoodrich, Nitto, and Pro-Trac, depending on the size. Within those offerings, buyers will see series such as g-Force Comp 2 AS, g-Force Phenom T/A, g-Force Sport Comp 2, NT555 G2, and Street Pro III.
The choice between brands is really a choice between the products offered in the exact size your Quattroporte uses. Comparing series, sidewall treatment, and any stated rim-width or load details will be more useful than choosing by brand name alone, particularly on a staggered front-and-rear application.
Restoration & Appearance
Which tire should I choose for a period-style 2021 Maserati Quattroporte?
A period-style approach on a 2021 Maserati Quattroporte starts with keeping the correct staggered front and rear size combination for the car's existing 19-, 20-, or 21-inch wheel package. Because this is a modern luxury performance sedan, the visual decision is usually less about vintage construction and more about sidewall presentation within the proper radial size.
For a cleaner contemporary look, Blackwall options keep the focus on the wheel design. On certain 20-inch sizes, raised white letter or Redline sidewalls can create a more expressive presentation, but appearance preferences should follow correct sizing and wheel compatibility rather than override them.
How does tire construction affect the appearance of a restored 2021 Maserati Quattroporte?
On the 2021 Maserati Quattroporte, primary fitment remains radial across all listed sizes, so construction choice is less about bias-ply versus radial appearance and more about the shape and visual character of the specific tire line. Sidewall treatment and profile are the main appearance factors a buyer will actually notice.
That means a restoration-oriented owner should focus on preserving the correct size, front-to-rear stagger, and wheel diameter first. Once those basics are right, the visible difference usually comes from choosing Blackwall, Redline, or raised white letter styling where available in the exact Quattroporte fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Maserati Quattroporte?
Yes. Wheel changes, altered offsets, suspension lowering, and other modifications can affect tire fitment on a 2021 Maserati Quattroporte even when the tire size itself matches a known Quattroporte application. That matters because this car uses staggered front and rear sizes tied to specific 19-, 20-, or 21-inch wheel packages.
A modified car should have its actual wheel diameter, width, and clearance checked before replacement tires are chosen. Steering clearance at the front and fender or suspension clearance at the rear are especially worth confirming if the Quattroporte no longer sits on its original wheel and suspension setup.
What should I inspect before driving a 2021 Maserati Quattroporte on new tires?
Before driving, inspect the wheel for correct diameter and visible damage, confirm that the front and rear tires are mounted in the proper staggered positions, and check inflation pressure carefully. It also makes sense to look over valve stems, tread seating, and any signs of rubbing once the car is back on the ground.
A short initial drive should be followed by another visual check for clearance issues and any unexpected air loss. On a performance-oriented sedan like the Quattroporte, making sure the correct front and rear sizes were installed on the proper wheels is just as important as choosing the right tire model.
What should I check before a longer drive in a 2021 Maserati Quattroporte?
Before a longer drive, confirm tire pressure, inspect tread and sidewalls for cuts, bulges, or cracking, and make sure the car is still wearing the correct staggered front and rear sizes. Any Quattroporte that has been stored for extended periods also deserves a careful look for aging or flat-spotting before highway use.
It is also wise to recheck wheel torque and look for any signs of uneven wear that could point to alignment or suspension issues. Since the Quattroporte uses multiple wheel diameters across its sub-model range, verifying that all four tires match the intended package can prevent problems before the trip begins.
