The 2015 Maserati Quattroporte blends Italian luxury-sedan character with the kind of long, low stance that makes wheel and tire fitment a major part of the car’s presence. By this point in the Quattroporte’s evolution, buyers were looking at a modern performance-oriented chassis with staggered front and rear sizing across several wheel diameters. This application uses radial tires in 19-, 20-, and 21-inch fitments, with different front and rear sizes depending on setup. Available choices include blackwall performance tires as well as RWL and redline options in certain 20-inch sizes. The key is matching the exact front or rear sub-model position before comparing appearance, series, and wheel compatibility.
Which Tire Size Is Right for The 2015 Maserati Quattroporte
The 2015 Maserati Quattroporte uses six primary tire sizes, and the right one depends first on whether you are replacing a front or rear tire and which wheel diameter the car carries. All of these are radial metric fitments, but the front and rear sizes differ, and the car appears with 19-, 20-, or 21-inch wheels. Before choosing a tire, confirm the exact position on the car and the actual rim diameter already installed.
The 245/35R21 size uses a 245-millimeter section width, a 35-series aspect ratio, radial construction, and a 21-inch rim diameter. On the 2015 Maserati Quattroporte, this is one of the front fitments used in the staggered setup, so it works as part of a matched front-and-rear pairing rather than as a stand-alone size choice. Its role is tied to the 21-inch wheel package, making wheel confirmation especially important before replacement. Choose this size only when the Quattroporte is equipped with the corresponding 21-inch front wheel and matching rear companion size.
The 245/40R20 size identifies a 245-millimeter-wide radial tire with a 40-series profile for a 20-inch rim. For the 2015 Maserati Quattroporte, it serves as a front fitment and offers one of the broadest product selections, including BFGoodrich, Nitto, and Pro-Trac choices with blackwall, RWL, and redline sidewall treatments. Series differences such as g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III give the buyer meaningful appearance and product-character options. This size deserves close attention when the goal is balancing modern road use with a more tailored visual presentation.
The 245/45R19 code denotes a 245-millimeter-wide radial tire with a 45-series profile on a 19-inch rim. On the 2015 Maserati Quattroporte, this is a front-position size used with the 19-inch wheel setup, so it should be matched to the correct rear size rather than selected in isolation. Available products in this size come from BFGoodrich and Nitto, primarily in blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. It is the right choice when the car retains its 19-inch front wheel configuration and the buyer wants to compare brand and series differences within that fitment.
The 275/40R19 size means a 275-millimeter section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. For the 2015 Maserati Quattroporte, this is one of the rear tire sizes, paired with the 19-inch front fitment in a staggered arrangement that gives the rear a broader footprint. BFGoodrich and Nitto options are available here, with blackwall sidewalls and several g-Force and NT555 G2 series choices that vary in specification and rim-width compatibility. Select this size only after confirming the car is using the 19-inch rear wheel setup rather than the 20- or 21-inch alternative.
The 285/30R21 code identifies a wide 285-millimeter radial tire with a 30-series profile for a 21-inch rim. On the 2015 Maserati Quattroporte, it functions as the rear component of the 21-inch staggered setup, so its fitment meaning is closely tied to matching the corresponding 21-inch front size. The very short sidewall and large rim diameter make it especially important to verify the actual wheel package already on the car before ordering replacements. This size is appropriate when preserving the 21-inch rear configuration rather than converting from another wheel diameter.
The 285/35R20 size combines a 285-millimeter section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2015 Maserati Quattroporte, it is a rear fitment for the 20-inch staggered setup and has strong product variety, including BFGoodrich, Nitto, and Pro-Trac offerings. Blackwall, RWL, and redline sidewall treatments appear in this size, along with series such as g-Force Comp 2 AS, NT555 G2, and Street Pro III. This is the rear size to evaluate when the car is already on 20-inch wheels and the buyer wants both performance-style and appearance-driven options.
Sub-model fitment matters on the 2015 Maserati Quattroporte because the covered applications are split by front and rear position and span three wheel diameters. Tire selection starts with identifying both the exact sub-model and whether the tire being replaced is on the front or rear axle.

2015 Maserati Quattroporte GTS Front
The 2015 Maserati Quattroporte GTS Front uses three possible front radial sizes tied to 19-, 20-, or 21-inch wheel setups. Tire selection here is mainly about confirming wheel diameter first, then comparing the available brand, series, and sidewall choices within the correct front size.
The 2015 Maserati Quattroporte GTS Rear uses three rear radial sizes that correspond to the matching staggered front packages. Rear replacement should follow the existing wheel diameter and pairing, with attention to whether the goal is a straightforward blackwall performance tire or a more distinctive sidewall presentation in the 20-inch setup.
The 2015 Maserati Quattroporte S Q4 Front shares the same front fitment pattern, with radial tire choices in 19-, 20-, and 21-inch diameters. The practical step is matching the installed front wheel size before comparing product series and appearance differences among the available tires.
The 2015 Maserati Quattroporte S Q4 Rear uses rear radial sizes that correspond to the car’s staggered 19-, 20-, or 21-inch wheel arrangement. Choosing correctly means confirming the existing rear wheel diameter and keeping the front-to-rear sizing relationship intact rather than selecting a rear tire by width alone.
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.
Best 2015 Maserati Quattroporte Tires for Sale
Available Quattroporte tire choices center on 19- and 20-inch radial fitments from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare blackwall performance tires across several g-Force and NT555 G2 series, with RWL and redline sidewall options appearing in select 20-inch sizes.
Quattroporte buyers usually need to sort out front versus rear sizing, wheel diameter, and the differences between available radial tire lines. The questions below focus on exact fitment, product selection, appearance choices, and practical road-use checks for this 2015 Maserati application.
Tire Size & Fitment
What tire size fits a 2015 Maserati Quattroporte?
The 2015 Maserati Quattroporte uses staggered radial tire sizes rather than one universal fitment. 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 both axle position and wheel diameter. A front 245 size does not answer the rear fitment question, and a 19-inch setup is different from a 20- or 21-inch package. Check the existing wheel size on the car before replacing tires, especially if the Quattroporte has been fitted with aftermarket wheels or a non-original wheel-and-tire package.
What size rim does a 2015 Maserati Quattroporte use?
The 2015 Maserati Quattroporte appears with 19-inch, 20-inch, and 21-inch rim diameters across the covered fitments. The 245/45R19 and 275/40R19 sizes use 19-inch rims, the 245/40R20 and 285/35R20 sizes use 20-inch rims, and the 245/35R21 and 285/30R21 sizes use 21-inch rims.
Rim diameter is the first measurement to confirm because tire size must match it exactly. A 20-inch tire cannot be mounted on a 19-inch or 21-inch wheel. On a Quattroporte, that check matters even more because the car also uses different front and rear widths, so proper replacement starts with the actual wheel diameter already installed at each end.
Do all 2015 Maserati Quattroporte sub-models use the same tire size?
No. The covered 2015 Maserati Quattroporte sub-model positions share the same overall front-and-rear fitment pattern, but they do not use one single tire size. Front applications use one of three 245-section sizes, while rear applications use one of three wider companion sizes.
That means sub-model name alone is not enough unless the axle position is also clear. A GTS Front and an S Q4 Front follow the same front sizing range, but neither uses the rear sizes. Confirm whether the tire being replaced is on the front or rear axle, then verify whether the car is on 19-, 20-, or 21-inch wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Maserati Quattroporte?
Start with the exact size, wheel diameter, and axle position. The 2015 Maserati Quattroporte uses staggered radial fitments, so the correct front tire may be 245/45R19, 245/40R20, or 245/35R21, while the rear uses a different companion size.
After the fitment is confirmed, compare the available tire series, sidewall style, and wheel-compatibility details in that exact size. Some Quattroporte sizes are offered only in blackwall, while certain 20-inch options also add RWL or redline styling. It also helps to check load figures, rim-width guidance, and whether the car still carries its original wheel package or a modified setup.
What sidewall styles are available for 2015 Maserati Quattroporte tires?
Blackwall is the most common sidewall style across the available 2015 Maserati Quattroporte tire selections. In select 20-inch sizes, especially 245/40R20 and 285/35R20, RWL and redline versions are also available through Pro-Trac Street Pro III.
That gives the car two different visual directions. Blackwall keeps the presentation modern and understated, while RWL or redline adds a more custom performance look. Because those appearance choices are tied to specific sizes, confirm the Quattroporte’s actual 20-inch front or rear fitment before choosing a sidewall treatment simply for style.
What brands offer tires for the 2015 Maserati Quattroporte?
Available Quattroporte tires come from BFGoodrich, Nitto, and Pro-Trac in the supported 19- and 20-inch sizes. Depending on the exact fitment, buyers may see BFGoodrich g-Force series options, Nitto NT555 G2 choices, and Pro-Trac Street Pro III tires.
Brand comparison works best after the exact size is settled, because not every brand or series appears in every Quattroporte fitment. Some sizes are limited to blackwall performance tires, while others add RWL or redline sidewalls. Once the proper front or rear size is confirmed, compare each brand by size availability, series character, and wheel-compatibility details rather than by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Maserati Quattroporte?
A period-style approach on a 2015 Maserati Quattroporte still begins with the correct modern radial size for the car’s actual front or rear wheel position. Since this is a contemporary luxury-performance sedan rather than a bias-ply-era application, the visual choice is more about wheel package and sidewall presentation than construction type.
For a restrained appearance, blackwall tires keep the car close to the clean, modern look expected of the Quattroporte. In certain 20-inch sizes, RWL and redline options create a more customized statement. Buyers focused on exact original-delivery appearance should compare any styling change against marque-specific references and the car’s existing wheel setup before making a cosmetic switch.
How does tire construction affect the appearance of a restored 2015 Maserati Quattroporte?
On the 2015 Maserati Quattroporte, construction is not a bias-ply-versus-radial decision because the covered primary fitments are all radial. Appearance is shaped more by wheel diameter, tire profile, and sidewall treatment than by switching between construction types.
That places the visual emphasis on whether the car sits on 19-, 20-, or 21-inch wheels and whether the tire is blackwall, RWL, or redline where offered. A lower-profile 21-inch setup presents differently from a 19-inch package even when overall tire diameter stays close. Matching the existing front-and-rear combination keeps the Quattroporte’s stance more coherent during restoration or cosmetic freshening.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Maserati Quattroporte?
Yes. Wheel changes, suspension lowering, spacer use, or non-stock offsets can all affect tire fitment on a 2015 Maserati Quattroporte, even when the tire size looks close to one of the standard front or rear sizes. Staggered setups leave less room for guesswork because axle position already matters.
A Quattroporte with aftermarket wheels should be checked for actual rim diameter, width, and clearance at both the front and rear before ordering tires. Steering lock, inner-fender space, and suspension travel all deserve attention. Matching the original size code alone does not confirm compatibility when the wheel package or ride height has been altered.
What should I inspect before driving a 2015 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 is set appropriately for the installed tires and vehicle use. It is also wise to check valve stems, balance quality, and basic alignment condition before putting miles on a fresh set.
A Quattroporte can be sensitive to setup because of its staggered arrangement and low-profile tire choices. Look over the suspension and steering for looseness, then verify there is no rubbing at full lock or over suspension movement. A short road test should include checking for vibration, pulling, and any sign that front and rear fitment was mixed or mismatched.
How often should tires on a 2015 Maserati Quattroporte be inspected?
Tires on a 2015 Maserati Quattroporte should be inspected regularly, not just at replacement time. Check them monthly for pressure loss, visible cuts, cracking, uneven tread wear, bulges, or impact damage, and give them a closer look before longer drives or after the car has spent extended time parked.
Low-profile performance radials can hide problems until ride quality or handling changes, so visual inspection matters. Pay special attention to inner shoulder wear, curb damage, and rear-tire condition on staggered setups where rotation options may be limited. Cars that see occasional use should also be checked for age-related deterioration and flat-spotting from long storage.
