2019 Maserati Tire Fitment Guide

2019 Maserati vehicles use seven radial sizes across three models. The Ghibli and Quattroporte use 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 GranTurismo uses 245/35R20 and 285/35R20 on 20-inch wheels. Rim width guidance appears within some 19- and 20-inch products, including 7.5 to 9 inches for 245/45R19, 8 to 9.5 inches for 245/40R20 and 245/35R20, 9 to 11 inches for 275/40R19, and 9.5 to 11 inches for 285/35R20.

That means there is no single 2019 Maserati tire size. Buyers need to identify the model first, then confirm whether the car is on a 19-, 20-, or 21-inch wheel package before choosing a tire. If you are replacing only one axle, confirm that the front and rear sizes still match the existing staggered setup. If you are changing wheels, use the rim-width guidance for the exact size rather than assuming one Maserati fitment transfers directly to another.

On a 2019 Maserati, 245/35R20 is a metric radial tire size. The 245 is the nominal section width in millimeters, the 35 is the aspect ratio, meaning the sidewall height is 35 percent of the width, the R identifies radial construction, and the 20 is the wheel diameter in inches. Within the 2019 Maserati range, that size appears on the GranTurismo.

Reading the code correctly helps separate fitment from appearance. A 245/35R20 is not interchangeable with a 245/40R20 or 245/45R19 just because the section width starts with the same number. The sidewall height and rim diameter both change, which affects whether the tire will mount properly and maintain the intended stance. For a GranTurismo owner, the code tells you immediately that you are looking for a low-profile radial on a 20-inch wheel rather than one of the sedan sizes.

No, 2019 Maserati models do not all use the same tire size. The Ghibli and Quattroporte share six sizes across 19-, 20-, and 21-inch wheel packages, while the GranTurismo uses a model-specific 245/35R20 and shares only 285/35R20 with the other two models. Every size in this year and make is radial, but the fitments themselves remain model-dependent.

That is an important distinction for anyone searching by year and make alone. A GranTurismo owner should not assume Ghibli or Quattroporte front sizes will cross over, and a sedan owner should not assume a GranTurismo front size belongs on a 19- or 21-inch package. Start with the model badge and actual wheel diameter, then confirm whether you are matching a front or rear position on a staggered setup before narrowing the product options.

2019 Maserati tire options are mainly Blackwall, which is the dominant sidewall style across 245/45R19, 275/40R19, and 245/35R20, and also available in 245/40R20 and 285/35R20. RWL, or raised white letters, appears in 245/40R20 and 285/35R20 through Pro-Trac Street Pro III. The 21-inch Maserati sizes do not have product coverage shown here, so the sidewall variety centers on the 19- and 20-inch fitments.

For most Ghibli, Quattroporte, and GranTurismo owners, a Blackwall tire will look the most natural on a modern Maserati. RWL creates a more overt performance appearance and changes the visual character of the car even when the size is correct. If appearance matters as much as fitment, choose the sidewall style before narrowing to a brand. That keeps you from selecting a tire that mounts correctly but does not suit the car’s intended presentation.

BFGoodrich, Nitto, and Pro-Trac cover the currently available 2019 Maserati sizes with products. BFGoodrich appears across every size that has product coverage here, including 245/40R20, 245/45R19, 275/40R19, 285/35R20, and 245/35R20. Nitto is also available in each of those same sizes, while Pro-Trac appears in 245/40R20 and 285/35R20 with RWL sidewalls.

Brand choice on a 2019 Maserati often comes down to the mix of sidewall look, speed rating, and the exact size you need. A buyer staying with a Blackwall performance radial has the broadest selection, while someone specifically wanting raised white letters will be focusing on the 20-inch sizes where Pro-Trac is present. It is worth comparing the same size across brands instead of comparing two different sizes, since the car’s fitment requirements come first and the brand decision comes second.

On several 2019 Maserati sizes, BFGoodrich offers both g-Force Comp 2 A/S and g-Force Phenom T/A, and the differences show up in speed rating, weight, and published load information. In 245/40R20, the Comp 2 A/S carries a 99W rating while the Phenom T/A carries 99Y and shows 1,709 pounds at 50 psi; in 245/45R19, the Comp 2 A/S is 98W while the Phenom T/A is 102Y with 1,874 pounds at 50 psi; in 275/40R19, the Comp 2 A/S is 101W while the Phenom T/A is 105Y with 2,039 pounds at 50 psi.

For a 2019 Maserati owner, that means two tires in the same nominal size can still differ in their stated speed ceiling and rated load. The W rating carries a 112 mph ceiling, while Y indicates 186+ mph. Those figures do not mean the car should be driven at those speeds, but they do help separate one product from another when you are comparing like-for-like sizes. Use those published distinctions, along with sidewall preference and wheel package, to narrow the right fit.

Several 2019 Maserati sizes have clear rim-width guidance. 245/45R19 fits rims from 7.5 to 9 inches, 245/40R20 fits 8 to 9.5 inches, 245/35R20 fits 8 to 9.5 inches, 275/40R19 fits 9 to 11 inches, and 285/35R20 fits 9.5 to 11 inches. Those ranges apply to the specific tire sizes rather than to every wheel fitted to every 2019 Maserati model.

That distinction matters if your car has aftermarket wheels or if a previous owner changed the wheel package. Two tires may share the same rim diameter but still want different wheel widths for proper section shape and support. Before mounting a new set, compare the actual wheel width stamped on the wheel against the acceptable range for the size you plan to run. That is especially important on staggered Maserati setups, where front and rear wheel widths are often different.

2019 Maserati tire options here are radial modern-performance sizes, and the 285/35R20 range includes a product explicitly marked TL for tubeless use. The other available products in these sizes are modern radial tires without tube-type markings. There is no sign of tube-type fitment in the covered 19- and 20-inch Maserati sizes, so buyers should treat them as tubeless applications unless a specific wheel condition or specialist recommendation says otherwise.

The more important question on a 2019 Maserati is usually wheel condition rather than whether the tire itself is a tube-type design. A damaged bead seat, corrosion, or a bent wheel can create sealing problems even with a tubeless tire. If the wheels are original and have seen years of service, inspect the valve stems and wheel sealing surfaces during installation. That approach is more useful than assuming every modern radial mounts the same way on every used wheel.

Original 2019 Maserati wheels can only be used with tire sizes that match their wheel diameter. A 19-inch wheel takes the 245/45R19 or 275/40R19 sizes, a 20-inch wheel takes the 245/40R20, 245/35R20, or 285/35R20 sizes, and a 21-inch wheel takes the 245/35R21 or 285/30R21 sizes. The shared 285/35R20 size spans all three Maserati models, but that does not make every factory wheel interchangeable.

Diameter is the first gate, and width is the second. Even within the same 20-inch family, a front fitment and rear fitment can call for different wheel widths, so moving tires around without checking can create mounting or handling issues. If you are reusing original wheels, confirm both the wheel diameter and the wheel width before selecting a new size. That is the safest way to keep the fitment true to the car’s intended wheel package.

A stored 2019 Maserati should sit in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that accelerate rubber aging. Keep the tires clean, maintain inflation, and move the car periodically if practical so the same contact patch is not carrying the load for months at a time. Because every fitment here is radial, long static storage is still a concern, but the flat-spotting behavior is generally different from older bias-ply tires.

Collector cars that spend long stretches parked often age out their tires before they wear them out. If the car will sit for an extended season, use a clean surface under the tires and avoid parking on bare ground or oily concrete. Some owners also reduce stress with cradles or stands placed correctly under the chassis, but the suspension should be supported properly if that route is used. Good storage habits preserve both ride quality and appearance.

Tires on a 2019 Maserati should be judged by age and condition as much as by tread depth. A practical collector-car rule is to start evaluating them closely once they are around five to seven years old and to treat about ten years as the outer edge for replacement consideration, even if the tread still looks healthy. The DOT date code on the tire sidewall tells you when each tire was manufactured.

That age-based approach matters because many performance cars accumulate low mileage but still experience rubber hardening, sidewall cracking, or internal aging. A 2019 Maserati that only comes out on weekends can still need tires sooner than the odometer suggests. If one axle was replaced at a different time, check all four date codes rather than assuming the set is the same age. Consistency in age and condition helps preserve balanced road manners on a staggered setup.

Tires on a 2019 Maserati deserve a quick inspection before every drive and a more thorough check before any longer outing. Look for pressure loss, outer or inner shoulder wear, punctures, sidewall cracking, cuts, bulges, and any sign that a tire has contacted a curb or pothole. Because these are low-profile performance sizes, wheel damage and hidden sidewall stress can be more significant than they appear at a glance.

A closer inspection is especially worthwhile if the car has been parked for weeks or months. Check the inside sidewalls as well as the visible outer face, since uneven wear often shows up where it is easiest to miss. If the tires feel unusually harsh, noisy, or unsettled after storage, have them checked before continuing to drive. Regular inspection is one of the simplest ways to catch an aging issue before it becomes a roadside problem.

2019 Maserati tires in these available sizes are modern radial performance tires, and the products with published speed ratings range from W to Y. A W rating carries a 112 mph ceiling, while Y indicates 186+ mph. Those ratings are well above normal U.S. highway speeds, so for typical road use the tire’s speed category is rarely the limiting factor when the tire is in good condition and matched to the correct wheel.

Highway safety still depends on more than the speed letter. Inflation, alignment, wheel condition, suspension health, and tire age all matter, especially on a performance-oriented Maserati with staggered fitments and short sidewalls. A fresh, properly mounted W-rated tire is generally a more meaningful safety advantage than an older, cracked tire with a higher speed letter. Choose the correct size first, then compare ratings within that size rather than treating the speed symbol as the whole story.

Inflation pressure on a 2019 Maserati should follow the vehicle manufacturer’s recommendation for the exact model, axle position, and wheel package, not a generic number from another Maserati size. Some available tires also publish maximum load and pressure figures, including 245/40R20 at 1,709 pounds at 50 psi, 245/45R19 at 1,874 pounds at 50 psi, and 275/40R19 at up to 2,039 pounds at 50 psi. Those figures are tire capacity ratings rather than day-to-day inflation targets.

Use the factory placard or owner’s manual as your starting point, then confirm that the selected tire is suitable for that application. Do not transfer a pressure recommendation from a 19-inch sedan fitment to a 20-inch or 21-inch setup, and do not assume front and rear pressures are the same on a staggered car. If a replacement tire has a different load index from the outgoing tire, that is worth reviewing before installation to keep the setup appropriate.

Before a longer drive in a 2019 Maserati, inspect each tire for visible cracking, punctures, bulges, uneven wear, and any signs of impact damage on the sidewall or wheel lip. Confirm cold inflation pressures, check that the valve stems are in good condition, and make sure the spare or emergency mobility equipment is present and serviceable if the car is equipped that way. On low-profile Maserati fitments, a wheel that looks only lightly scuffed can still deserve a closer look.

Tires are only one part of the preparation, but they are the part that meets the road. A longer drive is also the right time to check alignment-related wear, since an inner shoulder problem can go unnoticed during casual use. If the car has been in storage, take a short local drive first and pay attention to vibration, pull, or unusual road noise. That brief shakedown can reveal tire and wheel issues before you commit to distance.
