2023 Maserati Tire Fitment Guide

2023 Maserati vehicles use eight sizes across three models. The Ghibli uses 245/45R19 and 275/40R19 on 19-inch wheels, 245/40R20 and 285/35R20 on 20-inch wheels, and 245/35R21 and 285/30R21 on 21-inch wheels. The Quattroporte uses 245/40R20 and 285/35R20 on 20-inch wheels, plus 245/35R21 and 285/30R21 on 21-inch wheels. The MC20 uses 245/35R20 at the front and 305/30R20 at the rear, both on 20-inch wheels.

That means 2023 Maserati fitment is strongly model-specific and often staggered front to rear. A buyer should verify the exact model first, then confirm whether the car is on its 19-, 20-, or 21-inch wheel package before choosing a tire. For the sizes with published rim-width guidance, 245/40R20 fits 8.0 to 9.5 inches, 245/45R19 fits 7.5 to 9.0 inches, 275/40R19 fits 9.0 to 11.0 inches, 285/35R20 fits 9.5 to 11.0 inches, and 245/35R20 fits 8.0 to 9.5 inches.

On a 2023 Maserati, 245/40R20 is a metric radial size. The 245 is the section width in millimeters, 40 is the aspect ratio, R means radial construction, and 20 is the wheel diameter in inches. That size appears on certain Ghibli and Quattroporte front applications, not across every 2023 Maserati model.

Understanding the code helps separate fitment from product preference. Once you know the size is correct, you can compare available tires by sidewall style, brand, speed rating, and rim-width compatibility rather than guessing by appearance alone. In this size, the available speed ratings include W and Y, so even within the same nominal size, the intended operating envelope can differ between products.

No, 2023 Maserati models do not use the same tire size. The Ghibli and Quattroporte share several sedan fitments, including 245/40R20 with 285/35R20 and 245/35R21 with 285/30R21, but the Ghibli also has its own 19-inch pair of 245/45R19 and 275/40R19. The MC20 stands apart with 245/35R20 in front and 305/30R20 in the rear.

That difference matters because year and make alone are not enough to choose correctly on a 2023 Maserati page like this. A Quattroporte owner can often narrow the choice by wheel diameter, while an MC20 owner must match a very specific front and rear pairing. If the car has been upgraded with different wheels, confirm the actual wheel diameter and the tire size already mounted before replacing anything.

2023 Maserati tire choices include more than one sidewall appearance, but availability depends on size. Blackwall is the most common style across 245/40R20, 245/45R19, 275/40R19, 285/35R20, 245/35R20, and 305/30R20. RWL appears in 245/40R20, 285/35R20, and 305/30R20, while Redline appears in 305/30R20.

For a modern Maserati, Blackwall is the most natural visual match if you want to stay closest to the factory-era appearance. RWL or Redline choices create a more custom look and may appeal more to an owner building a personalized car than one preserving an original presentation. The best way to decide is to match the sidewall treatment to the personality of the specific car, especially if wheel finish and brake hardware are already visually prominent.

BFGoodrich, Nitto, and Pro-Trac cover the available 2023 Maserati sizes that currently have product support here. BFGoodrich appears in 245/40R20, 245/45R19, 275/40R19, 285/35R20, and 245/35R20. Nitto appears in 245/40R20, 245/45R19, 275/40R19, 285/35R20, 245/35R20, and 305/30R20, while Pro-Trac appears in 245/40R20, 285/35R20, and 305/30R20.

That brand spread gives buyers a useful mix of mainstream performance-oriented radials and visual alternatives in selected sizes. If your priority is keeping the look understated, Blackwall options are widely available across the range. If your priority is appearance on a custom build, Pro-Trac adds RWL and, in 305/30R20, a Redline option that changes the visual character of the car much more than a standard Blackwall tire.

On several 2023 Maserati sizes, both the BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A are available, but their published details are not identical. In 245/40R20, the Comp 2 A/S appears with a 29-pound weight and an 8.0 to 9.5 inch rim-width range, while the Phenom T/A appears at 28.06 pounds, the same 8 to 9.5 inch rim-width range, and a 1709-pound maximum load at 50 psi. Similar pairings appear in 245/45R19, 275/40R19, and 245/35R20, with the Phenom T/A carrying Y ratings where the Comp 2 A/S carries W in those overlapping sizes.

For a buyer, that means the comparison is not just branding but also details such as speed rating, load information, and small changes in weight. If you are choosing between those two series in the same size, compare the exact sidewall marking and the wheel width on your car before deciding. That approach matters more than treating all performance radials in the same nominal size as interchangeable.

Published rim-width guidance is available for several 2023 Maserati sizes. The 245/40R20 fits 8.0 to 9.5 inches, 245/45R19 fits 7.5 to 9.0 inches, 275/40R19 fits 9.0 to 11.0 inches, 285/35R20 fits 9.5 to 11.0 inches, and 245/35R20 fits 8.0 to 9.5 inches. Those ranges apply to the specific sizes rather than to every wheel that might appear on a Ghibli, Quattroporte, or MC20.

Rim width matters because two tires with the same wheel diameter can still be wrong for the same wheel if the wheel is too narrow or too wide for the tire’s intended shape. Before replacing tires on a 2023 Maserati, verify both the wheel diameter and the actual wheel width, especially if the car has aftermarket wheels or a previous owner changed the package. That check can prevent clearance, handling, and appearance issues.

The available 2023 Maserati products are radial performance tires, and one 285/35ZR20 tire is explicitly marked TL for tubeless use. The remaining sizes use modern radial size markings without tube-type markings in the tire designation. Nothing in these fitments suggests a traditional tube-type collector-tire setup like you would see on older bias-ply applications.

That said, wheel condition still matters. A 2023 Maserati owner replacing tires should confirm that the wheels are appropriate for tubeless radial service, that the valve stems are in good condition, and that no wheel damage or bead-seat corrosion is present. On a modern high-performance car, those basic checks are as important as the tire size itself because sealing integrity and balance quality directly affect road manners.

A 2023 Maserati should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, furnaces, welders, and other ozone-producing sources that can age rubber prematurely. Keep the tires clean, maintain proper inflation, and move the car periodically so the same footprint is not carrying the load for months at a time. Modern radials resist storage flat-spotting better than old bias-ply tires, but long static storage is still hard on any low-profile performance tire.

If the car will sit for an extended season, many collectors either roll it occasionally or support it in a way that reduces long-term stress on the tires and suspension. The practical goal is preserving casing shape, sidewall condition, and ride quality so the car feels normal again when it returns to use. Tire care during storage is especially important on a Maserati because the low-profile sizes used here have less sidewall cushion than a touring-car tire.

On a 2023 Maserati, age usually matters as much as mileage, and often more. A good rule is to begin evaluating tires closely once they are in the five- to seven-year range and to treat around ten years from the DOT date code as a serious replacement point even if tread depth still looks acceptable. That guideline is especially relevant for performance cars that may be driven seasonally rather than daily.

Low annual mileage can create a false sense of security because rubber compounds still age from heat cycles, time, and storage conditions. A tire that looks presentable can still harden, lose wet-weather confidence, or develop cracking as it ages. Checking the date code and inspecting the tire regularly gives a far clearer picture than basing replacement decisions on tread wear alone.

Tires on a 2023 Maserati should be inspected before every drive and again before any longer highway outing. Look for sidewall cracking, punctures, cuts, bulges, irregular shoulder wear, and any pressure loss that suggests a slow leak. Because these are low-profile high-performance sizes, impact damage from potholes or sharp road edges deserves especially close attention.

A quick inspection takes only a few minutes and can prevent much larger problems once the car is at speed. On a Maserati with staggered sizing, compare front and rear wear patterns separately rather than assuming they will age the same way. If the steering feels different, the car starts tramlining, or one tire loses pressure faster than the rest, address it before the next outing instead of driving around the symptom.

Yes, the available 2023 Maserati tires are modern radial performance tires, and the speed ratings shown here are well within normal U.S. highway use. W-rated tires carry a 168 mph ceiling, while Y-rated tires carry a 186 mph-or-higher ceiling in the overlapping sizes where both appear. Those ratings are far above legal interstate speeds, though they do not override the condition of the tire, the wheel, or the car itself.

Real-world highway safety depends on inflation, alignment, age, damage history, and the mechanical condition of the Maserati as much as on the speed letter molded into the sidewall. A Ghibli, Quattroporte, or MC20 with worn suspension parts or underinflated tires will not behave as intended even if the size is technically correct. Treat the rating as one part of the picture, not as a substitute for a full pre-drive check.

Inflation pressure on a 2023 Maserati should follow the vehicle’s factory placard or owner’s manual for the exact model and wheel package, not a generic number carried over from another size. Some available tires also publish maximum-load figures at 50 psi, including 1709 pounds for one 245/40R20, 1874 pounds for one 245/45R19, 1819 or 2039 pounds for certain 275/40R19 products, and 1521 pounds for one 245/35R20. Those figures are tire-capacity references, not a universal recommended running pressure for every Maserati application.

The practical takeaway is to separate manufacturer load capacity from the carmaker’s operating recommendation. Your Maserati’s ideal cold inflation setting depends on the exact model, axle, and wheel package, especially on staggered setups where front and rear needs may differ. Use the vehicle guidance first, then make sure the selected tire is capable of carrying the required load at its rated pressure.

Before a longer drive in a 2023 Maserati, inspect all four tires for cracking, punctures, sidewall bulges, exposed cords, uneven wear, and proper cold inflation. Confirm that the front and rear sizes match the intended staggered setup, and inspect valve stems and wheel lips for damage. If the car has a spare or mobility kit, check that as well before leaving.

Tires are only one part of a sound pre-trip routine on a modern Italian performance car. It also makes sense to check fluid levels, brakes, battery condition, and any warning messages before heading out, especially if the car has been sitting. Starting with the tires is smart because they are the car’s only contact with the road, and a long drive will quickly expose any weakness in pressure, age, or impact damage.
