2017 Maserati Tire Fitment Guide

2017 Maserati vehicles use seven sizes across three model lines: 245/35R21, 245/40R20, 245/45R19, 275/40R19, 285/30R21, 285/35R20, and 245/35R20. Ghibli and Quattroporte share the 19-, 20-, and 21-inch sedan sizes, while GranTurismo uses 245/35R20 at the front and shares 285/35R20 at the rear. Rim diameters span 19, 20, and 21 inches, so these are not interchangeable as a single universal fitment.

The practical takeaway is that year and make alone are not enough for 2017 Maserati fitment. You need the exact model and the front or rear position before choosing a tire, especially because the sedan range can appear with different wheel diameters depending on package. If your current tires are missing or the car has changed wheels over time, verify the wheel diameter directly before moving on to width, profile, or brand choice.

On a 2017 Maserati, 245/40R20 is a metric radial size. The 245 is the nominal section width in millimeters, 40 is the aspect ratio, meaning the sidewall height is 40 percent of that width, R identifies radial construction, and 20 is the wheel diameter in inches. On this year and make, that size appears on Ghibli and Quattroporte applications.

That code matters because it tells you far more than just overall size. It identifies the wheel diameter you must match, the basic sidewall profile, and the tire family you should compare against when reviewing brands and speed ratings. On a 2017 Maserati sedan, 245/40R20 is a front fitment, so pairing it correctly with the corresponding rear size is just as important as matching the size itself.

No. 2017 Maserati models do not all use the same tire size. Ghibli and Quattroporte share the same six sizes across 19-, 20-, and 21-inch staggered setups, while GranTurismo uses only two sizes here: 245/35R20 in front and 285/35R20 in the rear. The only size shared by all three model lines is 285/35R20.

That makes model identification essential before you narrow the choice further. A GranTurismo owner can quickly focus on a 20-inch staggered setup, while a Ghibli or Quattroporte owner may need to sort out whether the car is on 19-, 20-, or 21-inch wheels first. If the car has aftermarket wheels, checking the actual wheel and current tire size is the safest starting point.

2017 Maserati tire options are primarily Blackwall, which suits the modern luxury-performance look of the Ghibli, GranTurismo, and Quattroporte. RWL styling appears in 245/40R20 and 285/35R20 through Pro-Trac, while 245/45R19, 275/40R19, and 245/35R20 stay Blackwall only among the available products. That means sidewall choice depends partly on size, not just brand preference.

For most owners seeking an appearance closest to how a contemporary Maserati would normally present, Blackwall is the natural fit. RWL can create a more aggressive custom or muscle-inspired look, but it changes the visual character of a late-model Italian sedan or coupe more noticeably than it would on an earlier American performance car. Choose sidewall style with the same care you use in choosing wheel finish and stance.

2017 Maserati sizes are covered by BFGoodrich, Nitto, and Pro-Trac in the product range available here. BFGoodrich appears across every size that has product coverage, Nitto also spans each covered size, and Pro-Trac appears in 245/40R20 and 285/35R20. Brand choice therefore depends on your exact size first, then on sidewall style and speed-rating preference within that size.

For a buyer comparing options, it helps to treat each size as its own market rather than assuming the same lineup repeats perfectly from one fitment to another. A 20-inch front or rear size may offer a broader cosmetic spread because RWL enters the mix, while the 19-inch sizes keep the focus on Blackwall performance radials. Once the size is fixed, comparing series details becomes much easier.

For 2017 Maserati applications where both appear, BFGoodrich g-Force Comp 2 A/S and BFGoodrich g-Force Phenom T/A share the same basic radial sizing but differ in their stated speed ratings and, in some sizes, published load information. In 245/40R20, for example, the Comp 2 A/S is W-rated while the Phenom T/A is Y-rated, and the Phenom T/A carries a published 1,709-pound maximum load at 50 psi. Similar W-versus-Y differences appear in 245/45R19 and 275/40R19.

That makes the comparison less about whether either tire fits and more about the character of the specific product within the same size family. If you are matching a vehicle that sees regular highway use and you want to compare like-for-like details, look closely at the exact speed letter, load figure where published, and any rim-width guidance attached to the size you need. Those specifics matter more than the brand name alone.

Published rim-width guidance for 2017 Maserati sizes varies by tire size. 245/40R20 fits 8.0 to 9.5 inches, 245/45R19 fits 7.5 to 9.0 inches, 275/40R19 fits from 9.0 to 11.0 inches depending on the product, 285/35R20 fits 9.5 to 11.0 inches where that guidance appears, and 245/35R20 fits 8.0 to 9.5 inches. Those ranges apply to the tire size and product family, not automatically to every wheel that might physically bolt onto the car.

Before choosing a tire, compare the wheel width stamped on the wheel itself against the acceptable range for your exact size. This matters most on performance-luxury cars like 2017 Maserati models, where wheel packages and aftermarket changes are common. Staying inside the proper width range helps preserve sidewall shape and intended handling behavior, and it avoids forcing a tire onto a wheel that is too narrow or too wide.

2017 Maserati tire options here are overwhelmingly modern radial applications, and the one explicit tube marking appears on a 285/35ZR20 BFGoodrich product as TL, meaning tubeless. Other products do not consistently repeat a tube marker in the size line, but nothing here suggests a traditional tube-type fitment. On a modern Maserati wheel and tire combination, tubeless construction is the normal expectation.

Even so, the right approach is to confirm the sidewall marking on the exact tire you choose and to make sure the wheel itself is appropriate for tubeless service. That is especially important if the car has aftermarket or repaired wheels. A sound valve stem, a clean bead seat, and an undamaged wheel barrel are just as important to air retention as the tire’s own tube or tubeless designation.

A 2017 Maserati should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, welders, battery chargers, and air compressors. Keep the tires properly inflated, move the car periodically if possible, and avoid letting it sit for long stretches on one contact patch without attention. Modern radials tolerate storage better than older bias-ply designs, but they still age from time, environment, and inactivity.

For seasonal or low-mileage use, a clean, dry garage and a routine of checking pressure every few weeks go a long way toward preserving tire shape and sidewall condition. If the car will sit for an extended period, some owners use tire cradles or stands to reduce flat spotting and load concentration. Good storage habits protect not only tread life, but also the ride quality and appearance expected from a Maserati.

On a 2017 Maserati, tire age usually matters more than mileage because many of these cars see enthusiast or seasonal use rather than daily commuting. A sound rule is to begin evaluating tires closely once they reach about five to seven years of age and to treat around ten years as a point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the sidewall is the best starting point for establishing age.

Performance-oriented low-profile tires can look usable long after age has begun to affect the rubber compound. That means a Maserati with plenty of tread may still need replacement if the sidewalls are cracking, the rubber has hardened, or the tire no longer rides and grips as it should. Age-based inspection is especially important when buying a pre-owned car that may have spent years on older tires.

Tires on a 2017 Maserati should be inspected before every drive and again before any longer road trip. Check inflation pressure, look for cuts, bulges, punctures, irregular wear, and sidewall cracking, and make sure the tread is wearing evenly across the contact patch. Because these cars often use staggered front and rear sizes, inspect each axle on its own rather than assuming all four tires should wear the same way.

A more deliberate inspection every few months is worthwhile even if the car is driven rarely. That is the time to look at date codes, valve stems, bead areas, and any signs that storage conditions are affecting the rubber. Catching a problem early is especially valuable on low-profile Maserati fitments, where impact damage, underinflation, or age-related deterioration can show up before the tire has accumulated much mileage.

Yes, 2017 Maserati tires in these sizes are built as modern radials and several carry W or Y speed ratings, depending on the exact product. W-rated tires are rated to 168 mph, while Y-rated tires are rated to 186+ mph. Those ceilings are well beyond ordinary highway use, so the more relevant issue for most owners is matching the correct size and maintaining the tire properly rather than chasing maximum speed potential.

Roadworthiness still depends on the condition of the individual tire, the wheel it is mounted on, and the overall state of the car. Even on a modern Maserati, suspension condition, alignment, and brake health matter every bit as much as the speed letter on the sidewall. Choose a tire with the correct rating for the application, then make sure age, pressure, and wear condition support the way the car will actually be used.

Inflation pressure for a 2017 Maserati should start with the vehicle placard or owner’s manual, because factory pressure targets are vehicle-specific and often differ front to rear on staggered applications. Some tire products also publish maximum load and pressure figures, such as 245/40R20 at 1,709 pounds at 50 psi, 245/45R19 at 1,874 pounds at 50 psi, 275/40R19 at 2,039 pounds at 50 psi, and 245/35R20 at 1,521 pounds at 50 psi. Those numbers are tire capacity references, not a blanket recommendation to inflate every tire to 50 psi.

The right approach is to use the Maserati factory recommendation for normal driving unless the tire manufacturer directs otherwise for the exact product and application. Do not transfer a pressure figure from one size to another just because the tires look similar, and do not assume front and rear settings should match. Correct pressure affects ride, steering response, wear pattern, and the tire’s ability to carry its intended load.

Before a longer drive in a 2017 Maserati, inspect all four tires for cracking, cuts, punctures, bulges, and uneven wear, and confirm cold pressures before the car leaves the garage. Check that the front and rear sizes are correctly paired for the vehicle’s staggered setup, and look at the spare or mobility kit if the car still carries one. Any sign of vibration, repeated air loss, or curb-impact damage deserves attention before the trip begins.

Tires are only one part of the preparation on a performance-luxury car, but they are one of the easiest places to prevent trouble. A pre-drive check should also include brakes, fluids, battery condition, and suspension feel, especially if the car has been sitting. On a low-profile Maserati fitment, a tire that looks acceptable at a glance can still be the weak link if it is old, underinflated, or damaged at the sidewall.
