2020 Maserati Tire Fitment Guide

2020 Maserati vehicles in this range use six sizes: 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. Both the 2020 Maserati Ghibli and 2020 Maserati Quattroporte use the same full group of sizes, with the narrower 245-section tires serving the front fitment and the wider 275- or 285-section tires serving the rear fitment.

That means year and make alone are not enough to choose correctly, even though the two models share the same size family. The practical check is wheel diameter first, then axle position, then the exact size already fitted to the car. Where published rim-width guidance exists, 245/45R19 spans 7.5 to 9 inches, 275/40R19 spans 9 to 11 inches, 245/40R20 spans 8 to 9.5 inches, and 285/35R20 spans 9.5 to 11 inches depending on the tire.

On a 2020 Maserati tire, 245/40R20 means the tire is 245 millimeters wide, has a 40-series aspect ratio, uses radial construction, and mounts on a 20-inch wheel. That size appears on both the 2020 Maserati Ghibli and 2020 Maserati Quattroporte as part of a staggered setup, so it should be understood as a position-specific fitment rather than a universal all-around tire for every wheel on the car.

The code matters because it tells you more than wheel diameter alone. A 245/40R20 belongs with a specific overall diameter and sidewall height, and changing only one part of that code can upset front-to-rear balance or electronic calibrations. If your car currently wears 20-inch wheels, confirm whether you are replacing the front tire in a staggered package before choosing among the available Blackwall or RWL products in that size.

Yes and no. Both the 2020 Maserati Ghibli and 2020 Maserati Quattroporte share the same six tire sizes overall, but they do not use one single size in every position. Instead, Maserati uses three staggered pairings built around 19-, 20-, or 21-inch wheels, with a narrower front size and a wider rear size in each wheel-diameter package.

That shared size family is helpful because either model can point you to the same size pages, but you still need to match the exact wheel package on your own car. A buyer comparing model names alone could easily choose the wrong rear size or the wrong wheel diameter. Checking the tire sidewall on the car, the wheel itself, and the front-versus-rear arrangement will narrow the choice quickly.

Sidewall style depends on the size. The 245/45R19 and 275/40R19 products are Blackwall only, while 245/40R20 and 285/35R20 are available in both Blackwall and RWL form. For a 2020 Maserati, Blackwall is the more natural visual fit with the car's modern luxury-performance character, while RWL gives a more overtly performance-oriented aftermarket look.

Most owners trying to preserve a factory-like appearance will lean toward Blackwall, especially on a late-model Italian sedan where clean sidewall presentation suits the original design language. RWL can make sense if the car already carries a custom visual theme and the owner wants that detail repeated at the tire. Sidewall style does not change the size code, so the visual decision comes only after diameter and axle position are confirmed.

The supported 2020 Maserati sizes with active product coverage come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across 245/40R20, 245/45R19, 275/40R19, and 285/35R20, Nitto covers those same four sizes, and Pro-Trac appears in 245/40R20 and 285/35R20. All of them are radial offerings aimed at modern road use rather than vintage-style reproduction construction.

Brand choice for a 2020 Maserati is less about authenticity and more about matching the tire's intended use, sidewall appearance, and speed rating to the way the car is driven. BFGoodrich offers the broadest spread within the covered sizes, including W- and Y-rated examples, while Nitto and Pro-Trac add alternatives in selected sizes. Once the correct size is settled, comparing series details becomes more useful than comparing brand names alone.

For the 2020 Maserati sizes where both appear together, the BFGoodrich g-Force Comp 2 A/S and g-Force Phenom T/A differ most clearly in speed rating, published load detail, and slight weight variation. In 245/40R20, the Comp 2 A/S appears as a 99W tire at 29 pounds, while the Phenom T/A appears as a 99Y tire at 28.06 pounds with a published maximum load of 1,709 pounds at 50 psi. In 245/45R19 and 275/40R19, the same pattern continues, with the Phenom T/A carrying Y ratings and published load figures while the Comp 2 A/S versions shown carry W ratings.

That comparison helps owners who want to separate appearance from specification. Both belong to the same basic modern radial category and both suit a late-model Maserati's driving mission, but the details are not identical from one series to the other. If your decision is between those two BFGoodrich lines, verify the exact size, the speed category you want, and whether the published rim-width and load figures align with your wheel and intended use.

Published rim-width guidance varies by size and sometimes by tire within the same size. For 2020 Maserati applications, 245/45R19 fits 7.5 to 9 inches, 275/40R19 fits 9 to 11 inches, 245/40R20 fits 8 to 9.5 inches, and 285/35R20 fits 9.5 to 11 inches where that measurement is stated. The 275/40R19 group also includes an example concentrated at 9.0 to 9.5 inches, so the acceptable range is not always identical across every tire in the same nominal size.

That is why wheel diameter alone is not enough when replacing tires on a 2020 Maserati. Two tires can share the same size code and still differ slightly in their recommended wheel-width window. If your car has factory wheels, the wheel itself usually points you in the right direction, but any aftermarket wheel should be measured and compared against the specific tire's range before final selection.

The supported 2020 Maserati tires are modern radial products, and one 285/35R20 BFGoodrich version is explicitly marked TL for tubeless use. Other products in these sizes do not always spell that out in the same way, so tubeless marking can vary by product rather than reading exactly the same across every tire in a given size. Nothing in these covered sizes points toward a traditional tube-type collector application.

For a late-model Maserati with contemporary one-piece road wheels, tubeless fitment is the normal expectation, but the smart move is still to verify the sidewall marking on the exact tire and inspect the wheel condition before installation. If the car has been modified with aftermarket wheels, that extra check matters even more. Valve stems, wheel sealing surfaces, and TPMS-compatible service work deserve the same attention as the tire itself.

A 2020 Maserati should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, battery chargers, welders, or other ozone-producing equipment. Keeping the tires clean and properly inflated helps the casing hold its shape during downtime, and moving the car periodically can reduce the chance of long-term flat spotting. Modern radial tires resist storage-related deformation better than old bias-ply designs, but they still age when left parked for long stretches.

If the car will sit for months at a time, many collectors either roll it occasionally or support it in a way that reduces constant load on one small patch of tread. That is especially worthwhile on low-profile 19-, 20-, and 21-inch fitments, where any pressure loss becomes noticeable more quickly. Good storage habits preserve ride quality and sidewall condition and make the first drive after layup much less eventful.

Tire life on a 2020 Maserati is usually judged more by age, environment, and maintenance than by mileage alone, especially on cars that are driven seasonally or as second vehicles. A sound rule is to begin evaluating tires closely once they are around five to seven years old and to treat about ten years as a serious replacement point regardless of remaining tread. The DOT date code on each tire is the starting place for that timeline.

Performance-oriented radial tires can still look usable while age hardening, internal deterioration, or heat-cycle history begins to affect road behavior. A car that is seldom driven may age out its tires long before it wears them out. If your 2020 Maserati still has older tires with good tread depth, inspect the date code, check for surface cracking or stiffness, and use age as part of the replacement decision rather than tread alone.

Tires on a 2020 Maserati deserve a quick inspection before every drive and a more thorough inspection before any longer trip. Look for cuts, bulges, punctures, unusual shoulder wear, cracking, and any sign that one tire is losing pressure faster than the others. Because these cars often use staggered sizes with low-profile sidewalls, uneven wear can also reveal alignment or suspension issues sooner than on a taller-profile touring setup.

A short pre-drive walkaround catches many problems before they become roadside interruptions. On a longer outing, check cold pressures, inspect the spare if the car has one, and make sure valve stems and sensors are in good shape. Keeping inspection routine and simple is often more effective than waiting for a service interval, especially on a performance sedan that may not be driven every day.

A 2020 Maserati Ghibli belongs to the modern era, so original fitment was based around radial performance tires rather than bias-ply or vintage numeric sizing. Within this year and make range, the Ghibli uses the same six radial sizes shared with the Quattroporte: front sizes of 245/45R19, 245/40R20, or 245/35R21 paired with rear sizes of 275/40R19, 285/35R20, or 285/30R21 depending on wheel package. The important original-fitment principle is matching the correct staggered combination and wheel diameter.

For owners pursuing factory-correct presentation, the best approach is to confirm the exact wheel package the car left the factory with rather than assuming any of the six sizes belongs on every example. A window sticker, build sheet, dealer literature, or marque specialist can help sort out market- and option-specific combinations. Since authenticity here is about modern specification accuracy rather than vintage construction, sidewall appearance and exact size pairing matter most.

Yes, correct tire fitment still matters when showing a 2020 Maserati, even though the standards differ from a prewar or muscle-car restoration. Judges and knowledgeable enthusiasts will notice if the car sits on the wrong wheel diameter, carries a mismatched front-to-rear pairing, or wears an obviously non-factory visual treatment such as a sidewall style that clashes with the car's original luxury-performance character. On a modern Maserati, accuracy usually means preserving the intended staggered stance and contemporary radial look.

That does not mean every show requires one exact tire brand, but it does mean proportion and presentation count. A Blackwall tire generally reads more factory-like on a 2020 Italian sport sedan than a more conspicuous sidewall treatment. If the event has marque-specific judging, consult its rules before making a visual change, because the line between tasteful personalization and incorrect presentation can vary from one club or concours to another.

For 2020 Maserati applications where both appear in the same size, BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 overlap closely in basic mission but differ in some published details. In 245/40R20, the BFGoodrich version weighs 29 pounds and fits 8 to 9.5-inch rims, while the Nitto version weighs 28.88 pounds. In 245/45R19, BFGoodrich weighs 29 pounds with a 7.5 to 9-inch rim range and Nitto weighs 29.65 pounds, while in 275/40R19 and 285/35R20 the Nitto examples carry XL markings and W speed ratings.

That means the decision is less about one being universally right for every 2020 Maserati and more about which exact specification suits your wheel and driving pattern. If you are comparing the two brands in one size, check the sidewall marking, the speed category, any XL designation, and the rim-width window before narrowing the choice. Those details are more useful than broad brand reputation when the car already demands a precise staggered fitment.

Yes, the covered 2020 Maserati tires are modern radial performance tires intended for normal road use, and the products with visible speed symbols carry W or Y ratings. A W rating corresponds to 168 mph, while a Y rating corresponds to 186 mph or higher. Those ratings are well beyond ordinary highway speeds, so in normal driving the more important safety factors are correct size selection, proper inflation, sound wheel condition, and the car's overall mechanical state.

A 2020 Maserati is also a high-performance sedan with suspension, brakes, and electronic systems calibrated around specific staggered tire dimensions. Even a tire with a very high speed category is not a substitute for choosing the right front and rear sizes or keeping the car aligned and maintained. For highway confidence, match the exact size, inspect the tires regularly, and remember that real-world safety depends on the entire vehicle, not the speed letter alone.

Inflation pressure for a 2020 Maserati should begin with the factory placard or owner's manual for the exact wheel and axle configuration on the car. Some supported tires also publish maximum load and pressure figures, but those are tire capacity references rather than a blanket cold-pressure setting for every Maserati application. Examples include 245/40R20 at 1,709 pounds at 50 psi, 245/45R19 at 1,874 pounds at 50 psi, and 275/40R19 values up to 2,039 pounds at 50 psi depending on the tire.

Use those numbers to understand the tire's capability, not to replace Maserati's own recommended service pressure. A staggered luxury-performance sedan can call for different front and rear pressures, and those recommendations may also change with wheel package or load condition. Check the placard first, adjust when the tires are cold, and keep the four corners matched to the car's intended setup rather than borrowing a pressure figure from another size.

Before a longer drive in a 2020 Maserati, inspect each tire for cuts, punctures, bulges, cracking, and abnormal wear, then verify cold pressure at all four corners. Because these cars use staggered sizes, make sure the front and rear tires are in the correct positions and that no recent service swapped unlike sizes by mistake. Wheel condition, valve stems, and any pressure-monitoring alerts deserve attention at the same time.

A longer trip is also a good reason to widen the inspection beyond the tires themselves. Check fluids, brakes, lights, and the spare or roadside support plan, since a performance sedan with low-profile tires is less forgiving of neglected maintenance. Taking a few extra minutes in the garage is usually enough to catch the kind of pressure loss, wear pattern, or sidewall damage that would be easy to miss on a quick local drive.
