2013 Maserati blended grand touring character with modern high-performance engineering, giving buyers a choice between the two-door GranTurismo and the four-door Quattroporte. Both carried the brand’s familiar mix of Italian style, powerful drivetrains, and large-diameter wheel packages that make tire selection more model-specific than year-specific. Across 2013 Maserati vehicles, four distinct radial sizes appear, with only the 245/35R20 shared between both models while the remaining sizes depend on whether you have a GranTurismo or a Quattroporte. The first thing to confirm is your exact model and wheel diameter, because 19-inch and 20-inch fitments are both in play before you narrow the choice to the correct front or rear size.
Which Tire Size Is Right for Your 2013 Maserati
Four tire sizes are used across 2013 Maserati vehicles, and they vary by model rather than being universal across the full range. The main decision is confirming whether your car uses a 19-inch or 20-inch wheel package first, then matching the correct front or rear size for your GranTurismo or Quattroporte. Understanding that distinction before choosing a product saves time and ensures the right match.
Year(s): 2013|Fit(s): GranTurismo, Quattroporte|Construction: Radial|Rim: 20 in
245/35R20 is a radial metric size with a 245-millimeter section width, a 35-series aspect ratio, and fitment for a 20-inch wheel. It is available from BFGoodrich and Nitto in blackwall form, with W speed ratings appearing across the range and rim-width guidance centered around 8.0 to 9.5 inches where published. Because this size is shared by both 2013 Maserati models, it is one of the key crossover fitments for buyers comparing wheel packages across the year. Choose it when your car calls for a 20-inch front fitment and you want a modern radial in a contemporary performance size.
Year(s): 2013|Fit(s): GranTurismo|Construction: Radial|Rim: 20 in
285/35R20 is a radial metric size with a 285-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. It is specific to the 2013 Maserati GranTurismo, and it is available from BFGoodrich, Nitto, and Pro-Trac in blackwall and RWL sidewall styles, with speed ratings varying by product between W at 168 mph and Y at 186+ mph. Rim-width guidance reaches 9.5 to 11.0 inches where published. This is the size to focus on for GranTurismo rear fitment when you want to stay with the correct 20-inch staggered setup.
Year(s): 2013|Fit(s): Quattroporte|Construction: Radial|Rim: 19 in
245/40R19 is a radial metric size that denotes a 245-millimeter section width, a 40-series aspect ratio, and fitment for a 19-inch wheel. It is specific to the 2013 Maserati Quattroporte and comes from BFGoodrich in blackwall form, with speed ratings varying by product between W at 168 mph and Y at 186+ mph. Published rim-width guidance falls in the 8.0 to 9.5 inch range, and load figures reach 1,653 pounds at 50 psi on certain versions. Choose this size when your Quattroporte uses the 19-inch front fitment rather than the 20-inch package.
Year(s): 2013|Fit(s): Quattroporte|Construction: Radial|Rim: 19 in
285/35R19 is a radial metric size with a 285-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. It is specific to the 2013 Maserati Quattroporte, with BFGoodrich and Pro-Trac offerings in blackwall and RWL styles, and speed ratings varying by product between W at 168 mph and Y at 186+ mph. Published rim-width guidance spans from 9.5 inches up to 11.0 inches depending on the tire, and load figures reach as high as 1,930 pounds at 50 psi on certain versions. This size suits Quattroporte rear applications that retain the 19-inch staggered arrangement.
Year(s): 2013|Fit(s): Quattroporte|Construction: Radial|Rim: 20-in rim
295/30R20 is a radial metric size with a 295-millimeter section width, a 30-series aspect ratio, and fitment for a 20-inch wheel. Its role within the 2013 Maserati range is Quattroporte-specific, pairing the largest section width here with the lowest profile sidewall of the group. The practical takeaway is straightforward: this is a model-specific 20-inch rear fitment, so it should be matched to a Quattroporte that already uses the corresponding wheel package. Confirm the exact wheel and axle position before choosing a tire in this size.
Two Maserati models are covered for 2013. Tire size does vary by model, so identifying whether you have a GranTurismo or a Quattroporte is the first step before narrowing to the correct wheel diameter and front-to-rear fitment. Select a model below to explore model-specific tire history, sizing, and available products in more detail.
2013 Maserati GranTurismo
The 2013 Maserati GranTurismo was the brand’s elegant front-engine grand touring coupe, known for combining exotic styling with long-legged road manners. Its tire fitment centers on 20-inch wheels, using a staggered setup that separates the shared front size from a model-specific rear size. That makes wheel diameter easy to confirm, while front-versus-rear position remains the key detail before choosing tires.
The 2013 Maserati Quattroporte carried Maserati’s traditional formula into a high-performance luxury sedan, offering Italian character in a full-size four-door package. For 2013, it appears with both 19-inch and 20-inch wheel fitments depending on configuration, which is why model identification alone is not enough without confirming the wheel package as well. Front and rear sizing remains staggered, so the exact axle position matters once the wheel diameter is verified.
Sixteen products are available across five tire sizes for 2013 Maserati vehicles. 245/35R20 has four BFGoodrich and Nitto radial blackwall choices, 285/35R20 has four BFGoodrich, Nitto, and Pro-Trac radial options in blackwall and RWL, 245/40R19 has three BFGoodrich radial blackwalls, and 285/35R19 has four BFGoodrich and Pro-Trac radial choices in blackwall and RWL. Confirm the exact size first, and check each product’s speed rating before selecting.
These FAQs cover how 2013 Maserati tire sizing changes between GranTurismo and Quattroporte, what the metric performance sizes mean, which brands and sidewall styles appear in each fitment, and what to inspect on a low-use modern exotic before driving.
Size Basics & Fitment
What tire sizes fit 2013 Maserati vehicles?
2013 Maserati vehicles use five fitments across the GranTurismo and Quattroporte range: 245/35R20, 285/35R20, 245/40R19, 285/35R19, and 295/30R20. The shared size is 245/35R20, which appears on both the GranTurismo and Quattroporte. The GranTurismo uses 20-inch tires, pairing 245/35R20 with 285/35R20, while the Quattroporte can use either a 19-inch combination of 245/40R19 and 285/35R19 or a 20-inch combination of 245/35R20 and 295/30R20.
The practical takeaway is that year and make alone are not enough on a 2013 Maserati. You need the model, wheel diameter, and axle position before choosing a tire. Rim-width guidance where published runs 8.0 to 9.5 inches for the 245-section sizes, 9.5 to 11.0 inches for the 285-section sizes, and should always be checked against the actual wheel on the car before moving forward.
What does 245/35R20 mean on a 2013 Maserati tire?
On a 2013 Maserati, 245/35R20 is a modern metric radial size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. That size appears on both the GranTurismo and Quattroporte, making it the shared 20-inch fitment in the 2013 Maserati range.
That code matters because it tells you more than overall fit. A 245/35R20 belongs to a low-profile, large-diameter performance package, so it needs to be matched to the correct wheel and axle position rather than treated as a generic 20-inch tire. On a 2013 Maserati, it is most useful as a starting point when confirming a 20-inch front fitment before narrowing to brand, speed rating, and sidewall style.
Do all 2013 Maserati models use the same tire size?
No. The 2013 Maserati range does not share one universal tire size. The GranTurismo uses 245/35R20 and 285/35R20, while the Quattroporte uses either 245/40R19 with 285/35R19 or 245/35R20 with 295/30R20, depending on wheel package. Only the 245/35R20 appears across both models, and even then it does not replace the other front or rear fitments used elsewhere in the lineup.
That means a buyer cannot choose by year and make alone with confidence. GranTurismo versus Quattroporte is the first split, and 19-inch versus 20-inch wheels is the second. Once those are confirmed, the remaining choice is simply the proper front or rear size for that setup. Checking the sidewall of the current tires and measuring wheel diameter are the quickest ways to verify what the car actually uses.
Buying the Right Tire
What sidewall styles are available for 2013 Maserati tires?
2013 Maserati fitments are primarily available in blackwall form, with raised white letter options appearing in some 285-section rear sizes. Blackwall choices are available in 245/35R20, 245/40R19, 285/35R20, and 285/35R19, while RWL appears in the Pro-Trac versions of 285/35R20 and 285/35R19. The 245-section sizes stay visually understated, which aligns with the factory appearance most buyers expect on a modern Maserati.
For a Quattroporte or GranTurismo intended to keep a clean OE-style look, blackwall is usually the natural visual match. RWL changes the personality of the car and can appeal more to buyers who want a more customized or period-performance look rather than a contemporary luxury-sport presentation. Sidewall style does not replace size verification, so appearance should be the final decision after model, wheel diameter, and speed rating are already settled.
What brands make tires for 2013 Maserati vehicles?
2013 Maserati tire fitments are covered by BFGoodrich, Nitto, and Pro-Trac. The shared 245/35R20 size is available from BFGoodrich and Nitto. The GranTurismo-only 285/35R20 is available from BFGoodrich, Nitto, and Pro-Trac, while the Quattroporte-only 245/40R19 comes from BFGoodrich and the 285/35R19 comes from BFGoodrich and Pro-Trac.
That brand spread gives buyers different ways to approach the same basic fitment. Some will prioritize a familiar performance-tire name, while others may focus on a particular sidewall appearance in the rear sizes. The best approach is to start with the exact size and wheel diameter your 2013 Maserati uses, then compare the available brands within that fitment instead of trying to choose a brand first and forcing the size decision afterward.
What is the difference between BFGoodrich g-Force Sport COMP-2 and BFGoodrich g-Force Phenom T/A for the 2013 Maserati?
On the 2013 Maserati fitments where both appear, the BFGoodrich g-Force Sport COMP-2 and BFGoodrich g-Force Phenom T/A share the same basic radial size but differ in some published details. In 245/35R20, the Sport COMP-2 is shown at 28 pounds while the Phenom T/A is 27.14 pounds, and both fit 20-inch wheels with an 8.0 to 9.5 inch rim-width range. In 245/40R19, both use the same 19-inch diameter and 8.0 to 9.5 inch rim-width range, with the Phenom T/A carrying a Y speed rating where the Sport COMP-2 is W-rated.
That makes the comparison a matter of spec preference within the same size rather than a change in fitment category. If you are comparing two tires for the same 2013 Maserati front application, details like speed rating, weight, and how the tire complements your driving style become more important than basic dimensions. Always keep the comparison inside the exact same size code, because a strong spec difference never overrides the need for the correct wheel diameter and section width.
Fitting & Setup
What rim width do 2013 Maserati tires require?
Published rim-width guidance on 2013 Maserati fitments varies by size. The 245/35R20 and 245/40R19 sizes center around 8.0 to 9.5 inches. The 285/35R20 and 285/35R19 sizes reach from about 9.5 inches up to 11.0 inches depending on the tire, with one 285/35R19 version shown as narrowly suited to 9.50 to 10.00 inches. Those numbers belong to the tire size itself and should not be transferred across the range.
That matters because the GranTurismo and Quattroporte both use staggered sizing, and the rear wheel is not automatically interchangeable with the front just because the bolt pattern may be similar. A tire can have the right overall size code but still be a poor match for a wheel that falls outside the approved width range. Confirm the actual wheel width before mounting, especially when replacing only two tires on a 2013 Maserati.
Do 2013 Maserati tires require inner tubes?
2013 Maserati tires in these fitments are modern radial performance sizes, and one 285/35R19 product is explicitly marked TL for tubeless use. The rest of the range follows the same contemporary performance-tire pattern, with no tube-type markings appearing among these sizes. That places the 2013 Maserati firmly in the tubeless era rather than the collector-era tube-type world associated with older bias-ply fitments.
Even so, tubeless construction does not eliminate the need to inspect the wheel and valve hardware carefully. On a used Quattroporte or GranTurismo, bead-seat condition, valve-stem age, and wheel damage can cause air-loss complaints that look like a tire problem at first. If a 2013 Maserati has aftermarket wheels, confirm that the wheel itself is intended for tubeless service before mounting a new set.
Can the original 2013 Maserati wheels be used with both or all tire sizes?
No single original 2013 Maserati wheel setup covers all five fitments, because the range includes both 19-inch and 20-inch diameters. A GranTurismo uses 20-inch sizes only, while the Quattroporte can be found with either 19-inch or 20-inch staggered combinations. That means a 20-inch wheel cannot accept a 19-inch tire, and a 19-inch wheel cannot accept a 20-inch tire, even when section widths appear close.
Within a given diameter, the next question is wheel width and axle position. A front wheel sized for a 245-section tire is not automatically suited to a 285- or 295-section rear tire simply because the diameter matches. On a 2013 Maserati, wheel diameter gets you into the right category, but front-versus-rear width is what determines whether the original wheel can actually support the tire you want to mount.
Maintenance, Storage & Longevity
How should I store a 2013 Maserati when the tires are fitted?
A 2013 Maserati stores best in a cool, dry, dark garage away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate sidewall aging. Keep the tires at proper pressure, avoid prolonged contact with petroleum products, and move the car periodically so one section of tread is not carrying the same load for months at a time. These are low-profile radial tires, so they generally resist storage flat-spotting better than vintage bias-ply tires, but static storage still affects ride quality and casing shape over time.
For a GranTurismo or Quattroporte that sits through part of the year, a monthly roll-forward or roll-back is better than letting the car remain planted in one position indefinitely. If the storage period will be long, some owners also use stands or cradles to reduce sustained load. The goal is to protect both the tire and the wheel finish, since cosmetic and structural deterioration often begin during inactivity rather than while the car is being driven.
How long do tires on a 2013 Maserati typically last?
On a 2013 Maserati, tire age usually matters more than mileage because many grand touring and specialty-performance cars are driven less than daily commuters. A sound rule is to inspect tires closely once they reach the five- to seven-year window, then treat ten years as the point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the sidewall is the most reliable way to establish the tire’s age.
A lightly driven GranTurismo or Quattroporte can fool an owner into thinking low mileage means long service life, but rubber hardens and ages even when the tread still looks deep. Heat cycles, storage conditions, underinflation, and long periods of inactivity all affect service life. If a 2013 Maserati still wears older tires, replacement may be the smarter decision even before wear bars become the issue.
How often should tires on a 2013 Maserati be inspected?
Tires on a 2013 Maserati should be inspected before every drive and again before any extended highway trip. Look for sidewall cracking, punctures, unusual shoulder wear, tread damage, bulges, and any sign that one tire is losing pressure faster than the others. Because these fitments are low-profile and performance-oriented, damage from potholes and curb contact also deserves close attention.
A quick visual check is valuable, but periodic hands-on inspection matters too. Run your hand across the tread to feel for cupping or feathering, and pay attention to changes in steering feel that could point to alignment or pressure issues. On a 2013 Maserati with staggered sizing, uneven wear cannot always be corrected through rotation, so early inspection is the best way to catch a problem before it ruins an expensive tire.
Safety & Road Use
Are 2013 Maserati tires safe for highway driving?
Yes, the 2013 Maserati tire fitments here are modern radial performance sizes intended for real road use, and the speed ratings shown are well into highway territory. W-rated versions carry a 168 mph ceiling and Y-rated versions carry a 186+ mph ceiling, depending on size and tire choice. At ordinary U.S. highway speeds, the vehicle’s overall mechanical condition, alignment, brake health, and suspension condition are usually more relevant safety factors than the published speed symbol alone.
The important point is to match the exact size and use a tire with a speed rating appropriate to the car’s performance character. A GranTurismo or Quattroporte with old, underinflated, or damaged tires is a bigger concern than one wearing a properly selected modern radial. Safe highway use starts with fresh rubber, correct pressure, careful inspection, and a full chassis check on a performance car of this type.
What inflation pressure should I use for 2013 Maserati tires?
Inflation pressure on a 2013 Maserati should be based first on the factory recommendation for the exact model and wheel package, then checked against the tire’s own published limits. Some fitments here carry max-load figures such as 1,521 pounds at 50 psi for 245/35R20, 1,653 pounds at 50 psi for 245/40R19, and up to 1,930 pounds at 50 psi for certain 285/35R19 versions. Those figures are load-capacity limits for the tire, not a universal running pressure to apply across every size.
That distinction matters because front and rear pressures on a staggered Maserati are often not the same, and a 19-inch Quattroporte setup should not be inflated by copying values from a 20-inch GranTurismo tire. Use the placard or owner’s manual for the baseline, then verify that the tire itself is in good condition and holding pressure evenly. Recheck after seasonal temperature swings, which can noticeably affect a low-profile tire.
What should I check before taking a 2013 Maserati on a longer drive?
Before a longer drive in a 2013 Maserati, inspect all four tires for cuts, bulges, exposed cords, sidewall cracking, embedded debris, and uneven tread wear. Confirm cold pressure, check the valve stems, and make sure the spare or mobility equipment is present and usable. Since these are staggered performance sizes, also verify that each tire is mounted on the correct axle position and that no one has mixed an incorrect size into the set after a previous replacement.
A longer-trip inspection should also include the rest of the car because tire safety and vehicle safety work together. On a GranTurismo or Quattroporte, pay close attention to brakes, fluid levels, battery condition, and suspension behavior before heading out. If the car has been sitting, a short local shakedown drive is wise before committing to distance, since storage-related issues often appear only once the tires and driveline are fully warmed up.
